Suhner presents new SUNmic 60 Micro Motor System

SUHNER presents new grinding, milling and polishing system

Intelligent technology for tool and mold making

In many technical fields, ultrafine grinding is one of the tasks that gives the product its final polish – in the truest sense of the word. This applies equally to both precision and the visual appeal.

The new SUHNER SUNmic 60 micro motor drive system

One of the leading manufacturers of professional surface treatment tools and machines for over a hundred years, SUHNER now offers an innovative grinding, milling and polishing system, SUNmic 60.

The central element is an intelligent control unit with touch panel that can accept a range of micro motors and tool hand pieces depending on the application. The control part has modern features such as touch screen operation on a glass display, the option to save settings and a rotation speed regulator with tangible resistance.

Key settings are easily legible on a large digital display.



Micro motor system

The actual tools are driven by powerful micro motors whose 280 W place a lot of power in the user’s hand. The compact, brushless BL/DC motors provide an extraordinarily wide speed range of 1000–60,000 rpm and deliver a high torque. In practice, they can be compared with pneumatic technologies but do not need a compressed air supply, operate at lower energy levels and emit virtually zero noise, without exhaust air or oil mist emissions.

One further benefit is that they run virtually free of vibration. The high concentricity safeguards clean and reproducible results in all areas of operation. A special heavy-duty clamping system prevents the millers from shifting. Chuck diameters range from 2.35, 3.0 and 6.0 mm to 1/8 and 1/4 inch.

 
Flexible applications

The new SUNmic 60 micro motor system can be connected to a 90–240 V source, and can therefore be used anywhere in the world. It offers a large number of combinations. The tools range from straight, angle and filing hand pieces to belt grinders. The control unit can be connected to two BL/DC motors and an AC motor.

Advantage: The new control unit is compatible with available micro motors. This is a true multi-purpose tool for many applications.

The new system can be used everywhere a precision finish is desired – for instance, grinding, milling, brushing and polishing in tool and mold making; in aircraft, engine and motor building; in engine tuning; and much more. SUHNER offers a range of matching machines, tools and abrasives that have been tailored specifically to each of these applications. Also an illustrated mold making tool catalog is available.
 

The new SUNmic 60 micro motor system has been designed for complex milling, grinding, brushing and polishing work in tool and mold making; in aircraft, engine and motor building; and similar applications.

Together with the brushless BL/DC motors, the hand pieces deliver the maximum in performance.
The high concentricity and low-vibration running can only benefit the final results.

 

The most important properties of SUNmic 60:

  • Robust control unit with intelligent features and uncluttered digital display
  • Touch screen operation on glass display
  • Rotation speed regulator with tangible resistance
  • Two sockets for hand pieces with the new BL/DC motors and one for conventional motors with carbon brushes
  • Separate, nonvolatile rotation speed memory for each connection
  • Wide, continuous range of rotation speeds of 1000–60,000 rpm
  • High torque
  • Low-vibration running and noiseless operation
  • High concentricity of 0.01 mm
  • Manual and automatic workpiece clamping under high forces
  • Overload protection, dust and spray water protection
  • Option for connecting a pedal

Machining Long Aluminum Profiles

Aluminum profiles are produced in all shapes and sizes.

Often, these profiles can be very difficult to machine, because of the various shapes, sizes, number of operations required and cycle times needed. When a profile shape will not allow the holes to be punched and cycle time makes producing the parts on machining centers impractical, Suhner, with its modular design and broad assortment of spindle options, can now offer processors an ideal solution to their machining needs.

Suhner’s line of spindles for Profile Machining includes the popular MONOmaster Electric Driven, Pneumatic Feed Units, ranging in size from the smallest BEM-3 unit, capable of drilling up to a 3mm hole in mild steel, up to the BEM-28 unit, capable of drilling up to 28mm in mild steel and having 200mm of controlled stroke.  Many of the units in the MONOmaster line are available with other options, such as inline, direct drive units for the BEM-6 and 12S, as well as 1:4 speed increasers for the BEM-6 &6D units capable of speeds up to 14,400 RPMs @ 60 Hz.  With the larger BEM12 & 12D units, the option of 4:1, or 16:1 gear reduction is available, giving RPM speeds as slow as 40 RPMs @ 60 Hz.

JAC Products Uses Flex Shaft Drills for Increased Roof Rail Production

Franklin, Georgia Tier One automotive supplier realizes up to 70% greater output from its internally designed production equipment, utilizing Suhner advanced drilling technology

See the video here!

JAC Products (Franklin, Georgia) puts 30-40 million holes into approximately 6 million pieces of extruded and formed aluminum each year. The products made at this facility are used as roof rack rails on nearly every major automobile, mini-van and truck brand. This fact translates into a majority share of the North American vehicle market for JAC.

As Mike Traylor, the JAC tool room & die shop manager notes, “We build and maintain nearly all our own machinery here in our factory. That means the whole team must keep striving to find greater efficiencies and new ideas.” As a vertically integrated manufacturer, JAC operates hundreds of drilling stations in its Franklin factory, located on the banks of the Chattahoochee River in southeastern Georgia. In the company’s extrusion department, millions of pounds of aluminum are extruded annually from 6061, 6063 and 6463 alloys. The extruded shapes then move to the fabrication department, where they are formed and drilled on highly automated equipment to produce the finished products. Following a decorative and wear-resistant finishing operation, JAC performs the final assembly of the products and ships directly to the customer’s assembly line.

A tour of this facility strikes the visitor in several ways. First, there is a steady flow of material between departments and very little wasted motion, as every station at JAC is a dedicated operation producing an average of 100,000-200,000 left- and right-side rail sets per year for each specific automobile model.

JAC-Suhner_24A1691_small

Suhner motor/drill combination allows precise repeat holes

Another point of note is the openness of the machinery. That condition results, according to Traylor, from one very important supplier to JAC, one that has been a partner to this Tier One for nearly 20 years. Suhner Automation Division, based in nearby Rome, Georgia, supplies an assortment of flex shaft and direct motor-driven drilling units to JAC, where Traylor’s team of mechanical specialists incorporates them into the company’s internally-designed production equipment. Owing to the flex shaft design on many drills, the drive motors are removed from the cutting area, making accessibility much better not only for operators and maintenance personnel. This configuration also improves access to other equipment such as laser trackers and position sensors. “The bottom line, as they say, is that we get upwards of 60-70% more output from our equipment since we began using the Suhner solutions for our drilling,” notes Traylor. The previous drills used here were also prone to breakdowns and service problems, which caused unacceptable delays in production, especially as the industry transitioned to the just-in-time philosophy. As Mike comments, “If JAC was going to keep up with JIT, we needed a more reliable supplier and better ergonomics on our equipment to improve the output.” He contacted an associate from a previous company relationship, Charles Stitcher, the regional marketing manager from Suhner, who presented his company’s solutions in flex shaft and related drilling devices. “It was a light bulb moment for our company,” says Traylor, “because we knew we’d found an answer to a lot of our challenges.”

By taking the motors out of the drilling area, the JAC operators could have much freer access to the work product, while the maintenance personnel could access a single manifold in many cases to do repairs, routine maintenance or replace components. Most of the machines designed here are dedicated pieces of equipment, used to produce a single rail set for a particular model, then retrofitted or rebuilt for the next generation, next model year design, or a completely different vehicle by Traylor’s team. The flex shaft design gave the machine building and maintenance group at JAC a significant advantage and it has continued to benefit the company in many ways, according to Traylor. “We can now use a more compact work area concept, which saves operator steps. Seems like a little thing, but when you do the math and the motion study, it represents a huge annual savings for our company, without sacrificing any safety considerations for our workforce.”

As one might guess, JAC understands the fabrication process for putting holes into aluminum, whether for roof mounting, rivet placement, or trim assembly. Often, the angle of the drill must be oriented to the surface of the workpiece, rather than in a typical x-y planar arrangement. Here again, the flex shaft design of the Suhner drills pays big dividends for the machine designers at JAC, as it allows them to position the drilling mechanisms in various configurations and tighter proximities. This allows the required accuracies, secondary counterbore operations or other processing steps to occur. After working on nearly 500 machine builds at JAC, Mike Traylor says he’s been very impressed with the flex shaft drill and its adaptability on a wide variety of applications.

“On one rail set for a Ford vehicle and another for a Toyota vehicle, the old way would have involved one operator performing all the drilling, one step at a time. Today, we have up to 11 drills and a cutoff operation, all performed at once. The savings in setup time alone are off the chart.” He cites another job where the output was previously 1200 sets per day and is currently 1200 per hour.

Not all of the drilling here is done with flex shaft models, however. On several dedicated machining operations, various Suhner motor-mounted drills are utilized, including a specially designed system for sawing.

JAC-Suhner_24A1919_small

Jeff Cavalier, Mike Traylor and Alberto Blanco of JAC Products in Franklin, GA

Senior Launch Manager at JAC, Alberto Blanco, comments, “We need to hold +/- 0.1-0.2mm tolerances on the drilling and +/- 0.5mm on our cutoff lengths for our customers, so the Suhner equipment capability has been very favorable in helping us deliver our value proposition to customers.” Traylor adds that the drills are used virtually non-stop, so wear is inevitable, further noting the availability of Suhner rebuild kits, including o-rings and seals, makes maintenance much easier for his team.

Finally, Jeff Cavalier, the JAC engineering & facilities manager notes, “With the support we get from Suhner, we know Mike and his team can make it happen, every day, creating and maintaining the machines that get the job done for our customers. That’s a nice feeling.”

Suhner and WAGNER Partner to Optimize Threading Operations

Operations for the prep on tubings and pipes generally require multiple manufacturing steps such as cutting, chamfering, face-off, turning and tapping including thread milling or thread forming.

Higher part quantities usually combined with the need for different manufacturing steps demand efficient and time saving production methods to help reduce time and cost. Special purpose machines such as rotary & linear transfer machines, offer the best solutions to help obtain shorter overall part cycle times.

Suhner and WAGNER Partner to Optimize Threading Operations | Suhner Industrial Products

The machining of tubings begins from bar stock length
The transfer machine performs OD and ID turning incl. chamfering oerations followed by thread rolling.

An extensive background of experience with operations on transfer machines allows SUHNER to optimize a manufacturing process with standard or custom solutions for each machining application. One specific application is for large & long OD threads. These operations are extremely difficult and challenging for manufacturers, when trying to obtain shorter cycle times, simply because an OD threading operation by itself will dictate the overall machine cycle time.

SUHNER, in cooperation with WAGNER, a German manufacturer for OD thread rolling heads, has developed a special process, which allows threading operations in very short cycle times. A pneumatic cylinder-activated system is used to open and close the thread rolling head, which is equipped with multiple thread cutting or forming inserts.

Special unit BEX35 ISO40 equipped with WAGNER Z27-2 thread rolling head | Suhner Industrial Products

Special unit BEX35 ISO40 equipped with WAGNER Z27-2 thread rolling head allows optimized OD thread rolling operations and shortened machine cyle times

The work piece is fed from bar stock material. After a cut to length operation, it is machined by (3) Suhner BEX15 machining units with special Weldon tool holders. Operations include OD & ID and face turning. All units are equipped with a 1.5kW motor and high precision angular contact spindle bearings.

The most interesting station on this machine is the one for an OD threading operation, which is accomplished with a BEX35-ISO40 machining unit equipped with a WAGNER Z27-2 thread rolling head. In this operation, the thread rolling head is rotating and the work piece is stationary. The feed motion for this station is done with a CNC slide unit. In order to synchronize the thread pitch, both the BEX35 spindle and CNC slide are servo motor driven.
As soon as the threading operation is finished, the WAGNER thread rolling head with integrated inserts opens quickly to allow a fast return to the home position.

Opening and closing action of the head is accomplished by an internal BEX35 drawbar, controlled by a 3-position pneumatic cylinder.

This pneumatic cylinder is designed to make an additional stroke of 10mm. This allows for head and insert adjustments or replacements, depending on thread size.

Depending on length, a typical OD thread rolling cycle time ranges between 6 -10 seconds. Illustrated work pieces are steel tubings as used in the HVAC product industry. There are 7 part variations, each with a different thread size, pitch and length requirement. Thanks to the application of CNC servo driven spindle and slide components, customers can achieve very short changeover time, as well.
