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.

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.

Bertsche iJet waterjet deburring system built for Linamar combines waterjet deburring with part cleaning for one inline system.
Canadian automotive part supplier realizes significant gains with Bertsche-designed multi-function system in its plant
With factory floor space at a premium and capital equipment funds scarce, Linamar, a Tier One Canadian automotive part supplier, turned to Bertsche Engineering recently for an all-in-one part deburring, final rinse and drying solution.
Typically, complex machined automotive parts with multiple intersecting holes require feature-specific part deburring to insure that parts are burr-free. After deburring, parts also need a final cleaning/washing to insure removal of microscopic particles that might adversely affect performance. They are then preserved with a rust or oxidation inhibitor and dried for shipment (transport) to be assembled. Usually, this involves separate pieces of equipment linked by conveyors or robots to transport parts to each machine.
To solve the problem of densely filled factory floor space, Bertsche Engineering developed a machine that handles all these processes in one machine, in one deburring cycle. The machine takes oil and chip contaminated parts, previously machined on CNC milling centers and mill/turn machines, then selectively deburrs critical features using high pressure water, blasting chips out of internal cavities, knocking off all feather-edge burrs and fan washing the outside of the part, using a CNC for full cycle control.
Close-up shows parts infeed and outfeed station, where considerable space savings were realized by the customer, Linamar, a major Canadian Tier One automotive parts supplier.
This process is accomplished by a series of rotating lance nozzles that probe small diameter internal holes in order to blast feather edge burrs clean at intersection points and wash chips out of dead-end passages. External features are then blasted with a series of direct nozzles that release up to 10,000 psi of water at the burr while tracing the part edges. The part is then washed with high-pressure rotating fan nozzles. Note: When required, additional mechanical wire and filament brush tooled deburring stations can be incorporated into the Bertsche system to mechanically remove burrs.
The same machine moves the deburred part to an agitated wash and rinse station, where the part is rinsed, cleaned and preserved with an aqueous rust inhibitor (providing up to 24-day protection) and is finally dried. The part is then ready for final assembly.
Close-up shows parts being indexed over high-pressure (10,000 psi) waterjet nozzles for full wash cycle and rust-inhibiting aqueous coating process
