Noisy gear trains have been a common problem for gear designers for a long time. With the demands for smaller gearboxes transmitting more power at higher rpm and incumbent demands for greater efficiency, gear engineers are always searching for new ways to reduce vibration and limit noise, without increasing costs.
Some popular solutions to the noisy gear problem include enlarging the pinion to reduce undercut, using Phenolic, Delrin or other noise-absorbing products, where possible, or changing to a helical gear train. Other methods include tightening specifications to insure greater gear quality or redesigning the acoustical absorption characteristics of the gearbox. Occasionally, experimentation with gear ratios can limit harmonic frequency amplification, which otherwise can cause a gearbox to amplify noise like a finely tuned stereo system. The engineer can also study material and hardness requirements, so that modifications may be made to minimize heat treatment distortion or possibly eliminate the need for heat treatment entirely.
Particular attention must also be paid to gear geometry to insure maximum contact.
Another approach to the gear noise problem that yields good results is crowning or barreling of the teeth. This technique involves changing the chordal thickness of the tooth along its axis. This modification eliminates end bearing by offering a contact bearing in the center of the gear.
A second benefit of the crowning approach to gear cutting is the minimization of misalignment problems, caused by inaccurate machining of the casting, housing, shafting, gearboxes or bearing journals. Crowning can also reduce lead problems in the gears themselves, which causes the gears to wear unevenly and bind because of eccentricities and position errors. Obviously, a gear with a center contact is less affected by discrepant manufacturing or design; furthermore, one can reduce the backlash requirements and allow the gears to wear in rather than wear out.
Shaving is a secondary gear finishing operation done after rough hobbing or shaping to create the desired crown. Crown shaving has long been a popular method, especially in manufacturing coarse pitch gears. With the recent evolution of gear equipment capable of crowning while cutting, the need for shaving just to achieve a crown has been eliminated.
Two variations of the crown shaving method will produce a gear to compensate for off-lead or misalignment conditions.
One approach produces a crown by rocking the table during the reciprocation of work and cutter. The degree of crown is readily changed by this method. The other approach is plunge feeding, which requires dressing the shaving cutter to the desired crown. Generally, it is faster to plunge feed, but the technique can subject the cutter to greater wear. Of course, it is more difficult to change the crown, provided one starts with good quality gears. Shaving improves the quality of profile and reduces error in the gear tooth, through the cutting and burnishing action of the cutters.
The crown form can be produced on gear teeth in several other ways. One method is to shape the gear by use of a crown cam in the shaper back-off mechanism. The proper radius of the gear is calculated by using the amount of crown on the flank and the pressure angle of the gear. Unfortunately, the blocks, while not complex, tend to be expensive.
The advent of the latest generation of gear equipment has made two methods of crowning while hobbing popular. Both methods produce crowns by increasing and decreasing the center distance of cutter to workpiece. The first method utilizes physical copying of a template by a hydrocopying or mechanical following device. This allows taper hobbing or even the creation of sinusoidal wave forms, if desired. More recently, the second method, CNC hobbing, has become commonplace.
Depending on software limitations, CNC allows cutting gears in almost any desired form. A disadvantage to this approach is the high cost of the equipment, though the payback has decreased considerably, in recent years.
New CNC shapers can cut a crown gear or spline without the need for buying a special crowning cam. On our Gleason Pfauter P 300 ES, for example, we can crown by cutting a slight right and left hand helix angle along the face width of the part. This leaves the root diameter straight. We also have a Bourn & Koch Fellows MS 450 with a U-axis for controlling the back-off. It can be programmed to move the cutter spindle in and out during the stroking cycle to crown the tooth by cutting deeper at the ends of the face width and more shallow at the high point of the crown.
Who is using this gear cutting technology today?
Users of heavily loaded gears have been using crowning for quite some time. Another area ripe for the use of crowning is in the manufacturer of hydraulic wobble motors. Here, the application is strictly for misalignment problems rather than for noise
reduction. An allied area involves heavily loaded pinions used in actuators for aircraft control surfaces. Generally speaking, it is more advantageous to crown the pinion because it makes more revolutions per minute and may generate more noise. In this case, it is of paramount importance to compensate for load deflection. Unfortunately, few companies in the United States have been applying this technology to commercial fine pitch gearing. However. the few manufacturers who have tried it are most pleased with the results. Some users have reported a 5x to 10x reduction in noise, accompanied by less vibration, wear and power draw.
Prime candidates for use of the crowning technique are the small fractional horsepower motor manufacturers or anyone dealing with spur or helical pinions that are susceptible to noise or misalignment. Because crowning on foreign gear hobbing equipment has been available for a greater length of time, this method has been developed to a greater extent in Europe.
American manufacturers would be wise to take advantage of the availability of this kind of technology. Exploration of crowning as a solution to noise and misalignment problems can produce a real competitive advantage for gear manufacturers and users alike.

Practical Operation
The SCHÖMA machine factory opted for a cycle turning machine with Sinumerik 840D solution line CNC for the manufacturing of individual parts and small batches of locomotive wheels; this machine also features Siemens ShopTurn with Manual Machine function. This hardware and software solution combines the flexibility and benefits of conventional machining with the productivity and efficiency of a CNC and this is what tipped the balance in its favor for one customer.
Christoph Schöttler Maschinenfabrik GmbH (SCHÖMA) is based in Diepholz, Germany. The company specializes in the development and production of diesel-engine locomotives. The model range includes tunnel and shunting locomotives; service, field and narrow-gauge locomotives; handcars, passenger carriages and gang cars. Around 90 percent of the locomotives produced each year at SCHÖMA are destined for use in tunnel construction.
Each construction project brings its own specific requirements and each country through which the locomotives travel has different environmental and safety legislation. SCHÖMA uses a modular system to meet a diverse range of customer requirements and the resulting need for a variety of equipment and product versions. One of the tasks facing the company is working out how to equip the locomotives for transportation by rail on differing track widths. Another requirement is locomotives with driving wheels featuring diameters between 600 mm and 900 mm, depending on local track usage.
The right decision
Faced with even more demanding requirements in terms of production capacity and flexibility, SCHÖMA’s Managing Director, Christoph Schöttler, last year decided to add a cycle-control Seiger Record LC 1400 lathe to his inventory of machines. “We opted for a head turning machine, as we do not need a tailstock to produce driving wheels, axle bearing housings and gear wheels. It is working just as we envisioned, so we obviously made the right decision,” says Schöttler.
SCHÖMA constructs around 120 locomotives each year, which equates to 480 wheels. In addition, there are also repair orders, which increase the workload to between 560 and 600 driving wheels per year. These wheels are produced in two mountings from forged blanks on the cycle turning machine. The first mounting is used to machine the wheel flange on the reverse side and the wheel hub. The shaft locating bore is pre-turned. In the second mounting, the first task is to pre-turn the driving wheel profile, then the rolling circle level and the wheel shaft locating bore are finished.
Careful approach
The cycle turning machine is controlled by a Siemens Sinumerik 840D sl CNC, equipped with the ShopTurn software package with Manual Machine feature. If required, ShopTurn programming can be performed on a separate PC as part of an operator’s work planning, without interrupting the work sequences on the machine. The programs are routed to the machine via the network, where they are called up as required, depending on the workpieces to be produced. The Sinumerik CNC is used for both numerically controlled machining and manual operation with the ShopTurn’s Manual Machine functions. In manual mode with electronic handwheels, the machine behaves just like a conventional lathe with an actual value display.
During face and longitudinal turning, the process operates with the entered feed and spindle speed. The real highlight of the system is that every cycle can be used straightaway, without having to create a custom program. At SCHÖMA, the option for manual intervention is used for setting the zero point or for simple contours. Diameters are determined manually, if driving wheels have been newly profiled or if driving wheel profiles require resurfacing. The wheel profiles abrade as a result of the high loads experienced in heavy-duty operation or on poor-quality tracks or as a result of the driven wheels skidding.
“With a machine that uses only CNC, it is difficult to rework the driving wheels, as it is not possible to determine how much material needs to be removed. With this optional manual mode, however, users can adopt a careful approach. This sums up the ease of control,” explains Walter Horstmann, head of mechanical production and wheel set construction at SCHÖMA.
Siemens ShopTurn with Manual Machine for the job shop
After machine start-up, the basic MANUAL screen is immediately displayed and offers direct access to choosing machining options without having to create a parts program.
Machining procedures such as “taper turning” and “straight line face and longitudinal turning” can be executed immediately. The operator simply selects tool, feed speed, spindle speed and orientation, plus, if required, machining angle, then presses “Start”. The active direction is graphically displayed in the basic screen, using a compass rose symbol. All machining steps such as entry, thread grinding and drilling can also be started in manual mode.

I had a speaking engagement today where I spoke about Social Media to a Human Resource association. I was discussing how Twitter, blogging and YouTube work best when they go hand-in-hand with each other. This topic came up here at work recently and this is how I put it into perspective:
When you develop a great video presentation and bring it to a trade-show or conference, you don’t just set it up on a table and leave it playing in a loop all by itself. You don’t just start the presentation and leave it unattended do you? Instead, you are there ready to greet people who show any interest in the presentation you are running. You are there to answer questions, make conversation and interact with others. As we all know, this is called networking. Likewise social media, when used correctly establishes this same type of interaction. Videos on YouTube need to be associated with a website, or a blog where someone interested can go and interact and ask questions. Once a connection is made and a conversation is started, it is just like you are standing together at the trade-show, or in the conference room. Here, in the discussion that evolves, whether it be virtual or in person, you will decide whether continuing a business relationship or not is in your best interest. So in both scenarios (virtual or in person) the same objective is being met.
Likewise, it’s important that once you post something on YouTube you have methods in place to draw traffic to the video. This is where your website, Facebook, Twitter and blog will play their part in this dance of getting your online presence noticed. Social Media needs to work together and be in harmony with each other. Working together is the key to the success of your social media campaign as well as your overall marketing plan.
We have a client who posts videos on YouTube, at the end of their Print Ads in the trade magazines we print: “see our videos on YouTube”… how is that for the evolution of the ad/PR world? We now have our traditional print ads referring potential clients (and anyone else who is interested) to our client’s online presence. At least for right now, it seems you can’t effectively have one without the other.

I have seen many businesses that looked at social media as a passing phase… at least they were crossing their fingers and hoping it was. Others felt it wasn’t relevant to their type of business. This way of thinking has led to them simply “dabbling” in social media. Ultimately, they end up neglecting it and concluding “it doesn’t work”. When a business chooses to simply dabble or chooses to outsource social media negative results are almost always a certainty.
It is very common for us to hear “My son (or daughter) set up our Facebook page (twitter account, blog etc) but nothing ever came of it.” You cannot have an “if you build it, they will come” mentality when it comes to social media.
Your online presence needs to be built, given life and then it needs to be nurtured so it stays alive and grows bigger and stronger.
Twitter or posting a blog once in a while. It’s not about someone who already has a full time job at your company spending a few minutes each week, “checking things out“. Here is the truth about social media: the beginning, the setting it up is actually the least time consuming and the easiest part. Why? because no one has found you yet and no one has started to communicate and interact with you yet. You are also not developing content, researching what’s being said and what are good, relevant things for you to be talking about. Getting content out into the world takes time. What are people interested in and talking about? How do you or your clients contribute to that conversation? This is not about selling products it is about participating in a conversation so you become the “go to” person for information and guidance in the world that your business is part of. I hear people say all the time, “what’s the big deal? I’ll just throw some things up on twitter once in a while and blog once in a while.” Sure, that is great if you want to use social media as an outlet for your daily ponderings… but if you want to get paying clients out of it, it’s a whole different ball-game.
In the PR/ad world, we need to maintain this knowledge for our business to grow, but we also need to be a source and knowledge base for our clients so they can to look to us for expertise and guidance. How do we do this? We need to know about, speak about and write about anything and everything that is relevant to our world as well as theirs. We also need to know where our clients need to have a presence in order for social media to work for them. They look to us for knowledge and guidance and as their ad/PR agency; we better know what we are talking about.
Fryer Easy Turn Combination Lathe with Siemens SINUMERIK 840D sl CNC lets operators at Continental Machine program, set-up and run faster; critical for one-off operations
By definition, says Josh Johnson, vice-president, Continental Machine, Rockford, Illinois, his prototype and short-run production shop must constantly run lean. There can be no tolerating excessive programming, set-up or machining time of any kind, otherwise the shop loses and, in this economy, Johnson notes, that is simply unacceptable.
Continental Machine is a seven-person, 13,000 square-foot facility that houses a variety of CNC milling, turning, wire EDM, hole popping and grinding machines, as well as various sheetmetal and plastic injection molding machinery. Therefore, the shop is well positioned to produce a wide variety of metal and plastic prototypes used by its diverse customer base, which spans markets such as window hardware, bicycle components, automotive parts, chemical processing, medical devices and foodservice equipment. Materials processed here are just as wide-ranging, including aluminum, CRS, tool steels such as A2 and D2, zinc, brass, copper, bronze, titanium and a variety of engineered plastics such as glass-filled Delrin.
Recently, this job shop purchased a Fryer Easy Turn-21 CNC Combination Lathe, controlled by a Siemens SINUMERIK 840D sl numerical control. The two operators responsible for this machine upgrade at Continental had limited experience with CNC and none whatsoever with the Siemens protocol, as this was the first of its kind at the shop.
The Easy Turn-21 was particularly appealing to Josh Johnson, who comments, “The set-up is extremely easy. Teaching the tools, altering the lengths and diameters is kept very simple. After the initial learning curve, which took only a few days, the operators picked up on the conversational programming, right away. Also, one of the best features on the machine was that you could still turn the parts by using the electronic handwheel and just one function, such as hogging off material automatically or putting on a tapered thread.” He noted this feature was not only more comfortable for the operators, but it also allowed them to quickly and efficiently prove out part programs. Johnson commented that this would not have been possible on previous machines, owing to the flexibility of the control onboard the Fryer. The result has been a minimum 20% improvement in the overall cycle time on most part programs run at Continental. For this primarily prototype job shop, that fact translates into a substantial increase in the work product possible here.
Echoing this sentiment, Sue Ostrander, sales manager, Fryer Machine Systems, explained the process that led her company to select the SINUMERIK 840D sl numerical control for all its milling and turning machines, a move that was recently formalized by the company and announced to the trade.
“Since its inception 26 years ago, family-owned Fryer Machine Systems has based its operation on three core principles: build a quality product, price it fairly and provide quality service. This philosophy has allowed Fryer’s business to grow even in challenging times,” she said.
Fryer manufactures a diverse line of over 50 models of high-quality CNC machine tools in its 50,000 square-foot facility in Patterson, New York. Over the years, Fryer has become well-respected for its quality and innovation, throughout the job shop and production machining market segments.
“Moving to the Siemens 840D sl platform was the next step in Fryer’s ongoing commitment to provide our customers with the most innovative machine tools available in the market today,” Ostrander continued. “The Siemens solution allows machine tool end-users to achieve higher productivity through easy and intuitive features and step-by-step, on-screen programming. This enables them to dramatically reduce set-up, programming, and tooling times, while significantly increasing output.”
“The SINUMERIK 840D sl modular design allows us to take full advantage of the superior mechanical features in our machines,” continued Larry Fryer, president and CEO, Fryer Machine Systems. “Fryer has always been known for our easy conversational controls and the move to Siemens has allowed us to greatly enhance this feature,” Fryer noted. “The 840D sl menu-driven system combines an advanced geometry calculator that displays the part while the operator is programming it. Sophisticated solid model graphics allow the operator to verify the part program with more clarity than ever before,” he said.
Larry Fryer has also been impressed with the automatic tool set-up and easy part set-up, made possible by the Siemens CNC. Fryer explained that auto-run mode is where many operators experience difficulty. Siemens and Fryer Machine Systems worked together to create an electronic handwheel run mode that gives the operator a safer way to prove out program execution, both forward and backward, using a standard electronic handwheel.
Fryer further stated, “Siemens provides us with a highly flexible solution that is critical to our ability to meet the specific needs of each customer. Our enhanced capability to offer the same control for both turning and milling gives Fryer machines a unified platform that is very important to customers both in the short-term and for long range expansion. Coupled with Siemens quality and reliability, they are invaluable to us in competing in today’s aggressive marketplace.”
Johnson added this comment on the service and training received by his operators at Continental. “Siemens has been helpful and very thorough in their training and after-sale service. The ShopTurn program, being integral to the control, now enables us to accurately determine tool path, potential collisions, tool changes and real world run time. This makes our operators’ jobs much easier, with the added benefit of allowing us to estimate much more accurately than ever.” Johnson further noted the CNC has substantial hard drive space, thus allowing most programs to be stored directly on the machine, though the company does maintain a back-up system.

In this struggling economy, we have clients who’ve actually gone back to Marketing 101 and decided that tough times require more aggressive presence in the market.
Old customers and prospective new ones are being courted more often, both in print ads, direct mail (making a nice comeback as it’s now unique!) and online via blast email, regular newsletters and the inexpensive if rather impersonal vid conference.
The impact of such activity has had the collateral if unintended consequence of making our agency quite busy, this year. So thanks for that, clients!
Much more important is the fundamental tenet of marketing being applied here. They can’t buy from you if they don’t know you’re on the planet, to be blunt.
And, whether they’re currently buying or not, the ones who’ll stay in business are the targets of our messages for clients.
Having lived through four major recessions in business in my time, the theory has been proven true, time and again. Namely, companies who continue to maintain a presence in their market, by whatever means, come back faster and stronger than those who don’t. This is a fact and we have the evidence to prove it, for anyone interested.

Hennig custom enclosures on generators provided through W.W. Williams to huge dairy products processing plant in Michigan.
Machesney Park, IL-On a recent installation at the Ovid, Michigan processing plant of the Michigan Milk Producers Association (MMPA), the standby power generation system supplier, W.W. Williams (WWW) of Dearborn, Michigan, required an increased level of sound and environmental protection on the three generating stations, in accordance with the specs received from their customer’s architectural firm. They turned to their enclosure suppliers for assistance, as the challenges were many. For the complete package, the project was awarded to Hennig. As WWW’s Brunswick, Ohio-based project manager on the job, Al LaManna, puts it, “We’d begun to see Hennig as our go-to guys on enclosures, owing to the continued satisfaction we’d experienced with their levels of quality, engineering and especially responsive service.”
The Ovid facility of MMPA processes over three million pounds of milk per day, specializing in the production of liquid dairy blends, dry powders and bulk butter. These dairy ingredients are offered in spray-dried, liquid, condensed and instantized forms. Fluid products are typically loaded for bulk tanker or 55-gallon drum delivery, while powders are packed in 50 lb. bags, 25 kg bags or one-ton totes. Butter is produced in 25 kg cubes. Such production processes place substantial load on the local utility company’s power generation system and also create ambient dust contaminant challenges for the plant’s equipment.
During the construction process on the three enclosures needed for the standby power generators, extra attention was given to the insulation, silencers and electrical controls for the unit, to ensure proper functioning, sound attenuation and minimized environmental impact. These enclosures and fuel tank assemblies further required additional features, as mandated by the Michigan Department of 
Environmental Quality, including overflow protection valves with a spill box for fuel containment on the remote filling apparatus, fill panel alarm system with level switch, extended vents above the roof line, a special mastic coating on the bottom of the fuel tank and stainless steel fuel supply and return lines.
Following the submission of the complete specification and winning the job, Hennig engineers Christian Grobe and Robin Moore, as well as sales rep Matt Sopchyk, led the team that produced the enclosures at the company’s manufacturing/fabricating facility in Rockford, Illinois. Al LaManna had occasion to visit the plant during the construction and was impressed by the efficiency of the vertical integration. Hennig performs all metal fabrication, finishing and the rigorous testing to UL standards in-house. “Even a midstream specification change by our customer was handled at Hennig with no upset in the production schedule,” notes LaManna.
Founded in Columbus, Ohio in 1912, W.W. Williams has evolved from one of the nation’s largest industrial distribution, repair and service companies to a highly diversified solutions provider. They provide solutions to customers with technical / mechanical service and repair, remanufacturing, warehouse / supply chain management and service a varied customer base. Their products and services include diesel engines, transmissions, heavy duty truck repair, refrigeration, power generation and third party supply chain logistics services. Their customers comprise on-highway trucking, off-highway equipment, Department of Defense OEM’s, vehicle OEM’s, U.S. Military and marine enterprises. The company represents the MTU Onsite Energy group and specializes in gas and diesel engine systems, fuel cell systems, gas turbine systems and gen-drive engines, to provide primary, standby and continuous power.
As Territory Manager for the company, Todd James Rundhaug, observes, “We are constantly looking for quality component suppliers to
complement our MTU Onsite Energy power generating equipment. We began our relationship with Hennig in 2008 and have been extremely satisfied with the quality, workmanship, delivery and especially the after-sales sales support on their enclosures and fuel tanks. Due to a variety of factors, our types of equipment require highly specialized enclosures and UL Rated fuel tanks. The total service package from Hennig on these products has been excellent.” LaManna agrees, noting his customers’ repeat satisfaction with the full package supplied by Hennig. On this Michigan Milk Producers job, Hennig supplied the enclosures, each equipped with a heater, overhead lights, powered louvers, battery back-up lighting with NiCad battery power and GFI wall outlets.
Point man on the job for Hennig Enclosure Systems was Matt Sopchyk, who noted there were three enclosures needed for the onsite generators on this project. Each generator is a 2000 KW unit, with a sub-base fuel tank holding 3480 gallons of diesel. “Hennig design standards for this application included our complete in-house powder coating process for the enclosure walls, doors and roof sections over the all galvanealled steel construction. This job was finished in MTU gray, matching their gensets.”
The UL142 approved steel fuel tanks are finished with a phosphoric pretreatment high-pressure wash and then a 2-step polyurethane process. Hennig enclosures are of a semi-monocoque design, meaning the structural integrity and inner strength are engineered and built into every panel and roof section. This allows for clean and functional design, without the need for separate framing or additional substrate supports of any kind. Also, the Hennig fuel tanks are engineered and built in a similar way, with full interior baffling and sub-structure integrity to support the genset without the need for surface mounted I-beams to support the genset or the need for an additional, costly raised floor above the tank top. The tank top is the floor within the genset.

Kimray, Inc., an Oklahoma City-based manufacturer of control valves and related equipment for oil and gas producing companies, reports an 83% increase in their machining efficiency, achieved largely as the result of recently acquired CNC production equipment.
Founded in 1948 by Garman Kimmell, Kimray operates a 274,000 sq. ft. facility and employs over 400 people to serve its expanding customer base of oil and gas producing companies. Kimray machines iron, steel and aluminum, as well as thermoplastic materials, to build its comprehensive line of control valves, thermostats, energy-exchange glycol pumps, gas-operated pilots and other process control devices. Their products are used to control vessel and lead line temperatures, liquid level inside pressurized vessels, pressure drops and liquid/gas flow.
The company maintains a turnkey manufacturing facility, including dozens of lathes, grinders, turning, milling, sawing and bore finishing/honing machine tools, nearly all with CNC systems onboard. Originally, two machines were purchased, an Emco Maier EMCOTURN 420 MC PLUS and HYPERTURN 665 MC PLUS Lathes, each equipped with Siemens SINUMERIK 840D CNCs and SIMODRIVE 611D drive packages. As their productivity greatly increased, Kimray decided to purchase two more Emco Maier machines to keep up with increased demand for their products.
The company operates a host system for file storage and back-up on all part production data. As one operator of these lathes observed, “I liked the Fanuc 18i-T CNC we used on other machines in the shop, but, with the SINUMERIK 840D, you can do so much more, such as instant programming and cut and paste operations, while the machine is running or stopped. Each screen allows you to be very detailed about what you’re doing, such as separating your mains from your subs with your part and workpiece programs. I use the Siemens CNC for axis and spindle movements on both machines (Emco Maier 420 Dual Main and Counter spindle Machine and the 665 Main and Counter Spindle Machine). My programs and data can be recessed easily and transferred back to the machines (from the company’s main host system), as needed. I can run my programs out of workpieces and sub-spindles, including milling and stenciling out of the sub-programs. I use the parts program as my way to transfer files and folders to the main system and back again.”
He further commented on the controls, “On a typical set-up, I like the sensitivity of the CNC. Being able to move the axis only a ten thousandth at a time to a hundred thousandth at a time comes in very handy for me. I also like the program test feature, especially on new programs. Each tool has its own geometry page and up to four offsets, making things much less complicated.”
Lastly, regarding the machine builder, this operator noted, “I received lots of good advice and training from the folks at Emco Maier, especially Doug Poling. He’s also assisted me a few times by phone, when needed.”
In the manufacture of its oil and gas production controls, Kimray typically machines bar stock of 303, 304, 310, 316 and 17-4 stainless, as well as D-2 tool steel, 6061-T6 aluminum, brass, Delrin and Teflon. Cast iron, ductile, steel, stainless and aluminum are also machined here. The 83% increase in machining efficiency has been achieved, due to these four Emco Maier machines with Siemens CNCs, according to Kimray sources and company production data.
In determining the increase in overall machining efficiency at Kimray, VP of Operations David Hill commented, “Our commitment to run CNC machine tools has long been in place and the addition of the Emco Maier lathes with Siemens controls onboard are the latest steps in this process. We’ve literally had no problems with these machines, the CNC’s or the drives. When Kimray operators can keep running and producing parts in such a way, the impact on our overall efficiency is immediate and substantial.”
Mike Morris, Kimray’s Plant Engineer, added that “the control is strong and easy for the operators to use”. Over the years, the CNCs have been virtually bulletproof.”
From the builder’s perspective, Emco Maier shares Kimray’s appreciation for the performance of its CNC/drive package supplier.
“Our 420 machine enables simultaneous production of two parts without interruption or collision. The digital drives (Siemens SIMODRIVE 611D) produce dynamic performance in both the main spindle and X/Z axes,” commented the company’s Director of Sales Support Operations for Emco Maier USA. “Plus, programming is just the same as on any CNC lathe. Only one program is generated. The program for the second workpiece is simply transferred to the bottom system by means of a selector switch. No additional programming is necessary. As we like to say, twice as nice.”
The 665 Hyperturn machine enables true 4-axis machining plus full c-axis capability on both the main and counter spindles. The 665 uses some of the same programming features, plus the same digital drive system as the 420, but in a larger package.
