Rattunde Unveils New ACS + CFMtwin Machine

See Rattunde in Hall 6, Stand E-40 at Tube Fair in Dusseldorf, April 7-11, 2014!

Major German supplier of finished length tube and solid bar processing equipment offers dual tube cutting and finishing in one setup; produces up to 5000 pieces per hour with up to 40% energy savings

Rattunde ACS + CFMtwin machine for simultaneous dual tube processing; can produce up to 5000 parts per hour

Rattunde Corporation, a German-based manufacturer of finished length tube and solid bar production, today announces the introduction of the ACS® + CFMtwin machine, the newest member in the company’s family of tube production systems.  Equipped with a specially-designed twin machining head that fits onto the standard head, this new machine can cut two tube or bar sections simultaneously, then machines both ends of both workpieces, also simultaneously.   This new Rattunde machine can produce up to 5000 finished pieces per hour.  The option also exists for single tube or bar production on the same machine.

The ACS® + CFMtwin machine, when in twin mode, can process two workpieces of 10mm to 41.5mm OD each into finished lengths from 10mm to 1500mm.  Example:  21mm OD x 3.5mm wall x 45mm length cut from a 6.5 meter mill length of stock material, based on carbon steel.  When the twin head is removed, the standard machining head can process a single workpiece up to 105mm OD.

In addition to the twin workpiece processing, this new Rattunde machine offers the OEM or production house all the capabilities found on Rattunde’s ACS® family of tube and bar production systems, including secondary brush deburring, end machining (chamfering and facing), inspection, washing, drying and robotic packaging.  The entire machine and all auxiliary workstations are motion-controlled by CNC from a single operator station for maximum efficiency.  The ACS® + CFMtwin is built on the same platform as the existing and popular Rattunde ACS® + CFM and ACS + CFMcurve systems.

Even when processing in twin mode, the setup time for a new job can be under 15 minutes, according to Rattunde engineering.  Other standard features on this new Rattunde machine include data management on all workpiece parameters (approx. 10,000 workpieces), data logging of every part produced for full part traceability, material lead and end edge detection for minimized crop cut and tag end.  All operating limits are set from the control panel, with continuous tool break monitoring for the saw blade and all cutting tools.

Alec Banish, director of business development at the company, states, “This new machine clearly gives us a decided advantage in the market for high-production requirements.  Plus, with the standard machining head still in place on the machine, the ACS® + CFMtwin can be a highly flexible, adaptable production system for many types of manufacturing operations as well as a wide variety of end product producers.”  

Because the machine offers essentially double the production in the same machine footprint, up to 40% energy savings have been documented on a 25mm OD x 3mm wall x 42mm long piece from a stock length of 6 meters in a typical batch count of 45,000.

Rattunde Building New Facility to Manufacture in America

Major German supplier of  finished length tube and solid bar processing equipment to open new 30,000 square-foot facility in Grand Rapids area for tooling and component manufacturing; plans in place to expand for full machine builds

image003

New Rattunde facility underway in Caledonia Township, Michigan, near Grand Rapids, due to open in April, 2014.

Rattunde Corporation, a German-based manufacturer of finished length tube and solid bar production systems, has been operating in the North American market for over seven years.  The company’s success during that time has resulted in today’s announcement by Rattunde Corporation President Richard Stadler of plans to build a 30,000 square-foot facility near the company’s current location in Grand Rapids, Michigan.  14 acres of land have been purchased by the company in nearby Caledonia Township and work has begun on the new facility, scheduled to open in April, 2014.

The plant will continue to house the North American sales and service operations and will allow for expanded spare parts inventory and manufacturing operations, including the production of tooling and various machine components.  Area within the new facility will also house a technical center with a machine onsite at all times for demonstration and training.  Future plans call for an expansion of the building to over 100,000 square feet, enabling Rattunde to produce their entire finished length tube and solid bar production systems here.  This decision was reached, after an analysis of the current and anticipated business needs of the company, according to Stadler.  “Our growth in North America has been rapid, though not unexpected, due to the unique nature of our equipment and the reliability and performance characteristics of our machines.”   Stadler further noted that solid growth of the company into diverse markets throughout North America made the new facility a logical choice.

image002In commenting on the new facility, Richard Stadler noted, “There were several reasons why we wanted to remain in the greater Grand Rapids area, but one of the main reasons is the excellent talent base here.  Companies are built on people and, whether you are looking for an experienced veteran of industry or a fresh graduate from one of our ranking high schools, colleges, or universities, outstanding people can be found here.”

Concurrent with this development, Rattunde has expanded its workforce with technical service and administrative personnel.  As Stadler explains, “Whenever a machinery company grows quickly, there’s an ever-present need for more customer service and technical personnel.  Of course, new people must be found and trained.”  But, Stadler went on to explain that rapid growth also means working smarter.  Rather than waiting for a customer to reach out to Rattunde in a time of need, Rattunde is proactively sending technicians to the customer and performing comprehensive machine inspections, identifying and correcting small issues before they become large ones.

image004

In the end, Stadler says, “This new facility will solidify our North American presence in the high-volume tube and solid bar production markets, thus benefiting our current and future customers in many ways.  It’s a purpose-built building, with a forward-looking eye on all we will need to build our machines and systems from the ground up.”  Rattunde will continue to occupy its current facility until completion of the new facility.

IMTS Pre-show News…Rattunde Booth N-6737

Integrated Sawing and Machining Center Sets New Industry Standard

Rattunde Corporation introduces the ACS + CFMcurve integrated sawing and machining center, an exciting new technology, at the IMTS show, McCormick Place in Chicago, from September 10-15, in the North Hall Booth #6737.   A fully operational system will be producing a variety of parts, demonstrating the fully automated flexibility of this manufacturing center.

The ACS Sawing Machine is the new industry standard for cold saws.  It utilizes a proprietary sawing algorithm with servo motor controlled feed to continuously adjust critical sawing parameters during each cut.  The results are the fastest sawing times, best surface finish and longest blade life available on the market.

The CFMcurve machining center is a patented Rattunde process that simultaneously machines each workpiece end, using 12 independent servo-controlled axes.  Machining options include: threading, boring, profile turning, grooving, radius edges and angled chamfering.  Programming screens guide operators for quick setup on even the most complex part geometry.  No special programming is required.

Precision parts are made in one continuous process with no operator intervention.  Bundles of mill length stock, up to 16.5 meters (54’) long, are placed in an automatic loader, individually separated and fed to the sawing process.  Cut parts are then transferred to the CFMcurve machine for precise finishing.  Utilizing advanced CNC controls, linear ball screws and servo motors, all mechanical motion is seamlessly integrated into the machine design for full process control.

The technology incorporated on this manufacturing center delivers production rates and quality unmatched by the competition.  For example, a tubular component of 70mm diameter, wall thickness of 5mm, material type ST52-3 BK, with a length of 150mm, machined with a 30 degree chamfer on the ID & OD with a faced end has a saw time of .96 seconds, a machined time of 1.86 seconds and the machine can produce 1,820 parts per hour, inspected for length and automatically packaged.  Cut length tolerance of +/- 0.15mm at 1.67 CPK and a machined length tolerance of +/- 0.05mm at 1.67 CPK are maintained with consistency.

The operator interface saves part files for instant recall when changing parts.  Servo motors move all cutting and machining tools to their exact positions and implement saved parameters.  No tooling change is required in the ACS Saw within a diameter range of 10mm; there is a 5mm diameter range in the CFMcurve.  Tooling change for the complete system takes less than 20 minutes, when necessary.

All critical sawing and machining parameters are monitored and controlled.  Clamping forces and position, saw blade torque and vibration, plus machining insert torque are continuously displayed and monitored.  Operating limits are set and machine functions stop when they are not met.  Saw blade and tooling insert wear is predictable and consistent.  Key data for each part produced are stored in memory for statistical evaluation.  All guesswork is removed for the operator.

Rattunde sets a new industry standard for manufacturing with this machine, replacing slow and unreliable processes with a complete manufacturing center.  Bar feeding lathe machines rely on a slow cutoff process, restrict the length of incoming stock and are not always capable of finishing both part ends simultaneously.  Cutting in a conventional saw, dropping parts in a bin and eventually loading them to a conventional machining center is time consuming, labor intensive and creates excess inventory with a loss of process control.

 Additional processes, engineered and manufactured by Rattunde, are easily integrated with the ACS + CFMcurve, including: part inspection stations, washing and drying, automatic packaging and automatic container changing, all available to further automate customer manufacturing.  The system being exhibited at IMTS will include part inspection and automatic packaging.

The ACS + CFMcurve is available in three models with diameter ranges from 10mm to 102mm, 10mm to 136mm and 10mm to 169mm, with finished part lengths from 10mm to 3500 mm.  All material types can be processed.

Rattunde Utilizes Precision Motion Control For Tube and Bar Production System; Up To 11,000 Parts Per Hour Reported with Zero Rejects

Through the use of Siemens SINUMERIK CNC technology, plus PLC and HMI, on a combination servo-controlled cold saw cut-to-length and brush deburring system, Rattunde customer achieves triple the output on small engine exhaust components

Rattunde ACS + BDM tube and bar production system at Cosmos.

Rattunde Corporation of Grand Rapids, Michigan is the five-year-old subsidiary of Germany’s Rattunde & Co. GmbH, a machine tool builder of tube, pipe and bar processing equipment.  The company is already making its mark in the American manufacturing industry, as demonstrated by a recent success it had at Cosmos Manufacturing of South Chicago Heights, Illinois, a major supplier of small engine exhaust tubes to the leading outdoor power equipment manufacturers in the country.

The Rattunde system, incorporating a servo-controlled cutoff saw and brush deburring mechanism, is consistently producing up to 11,000 parts per hour at Cosmos, according to Mike Jemilo, the end user’s general manager.  “This number represents triple the output production for Cosmos.” He continues, “Better still, it’s been in operation more than a year and we have not reported a single reject, with only routine maintenance and zero downtime due to machine problems.  This is truly a win-win scenario for the machine tool builder and us alike.”

At the heart of the Rattunde system, according to Richard Stadler, company president, is the computer numerical control (CNC) system used by this builder.  It consists of a Sinumerik 840D CNC, Simatic S7 PLC with various analog and Profibus modules, plus numerous Simotics servomotors, motor protection devices, circuit breakers and other components supplied by Siemens.

Machine performs all servo-controlled saw cut-to-length, washdown, brush deburring and packing operations on a single line, controlled by Siemens CNC and HMI.

At Cosmos, this Rattunde system is used to process mill-length tubes to customer-specified dimensions, using a fully NC-controlled cold saw.  Cut-to-length parts are then automatically measured for dimensional accuracy and brush deburred.  Production of these parts runs up to 11,000 units per hour, according to Cosmos’ Mike Jemilo.  Because of the overall improvements in automation, speed and parts handling, plus the precision of the Sinumerik CNC system, Cosmos is further experiencing significant reductions in parts handling, secondary operations and final assembly.

The primary products being produced on this equipment at Cosmos include mountings, connectors and sections for muffler tubes in dozens of lengths, typically in 3/8-inch, 7/16-inch, 12 millimeter and 1/2-inch sizes.  Products are routinely run in mild steel, aluminized steel and stainless steel on the same Rattunde system, with offline pre-programming done by the Cosmos engineering team.  The final products are sold by Cosmos to leading manufacturers of chain saws, leaf blowers, lawn mowers and other small engine-powered equipment.

All machine functions and 13 axes of movement are affected by the Siemens CNC, which also provides remote monitoring capability for the builder Rattunde.

Jemilo concluded by citing the Rattunde service advantages. “From the initial contacts with their application engineering, through the build process, commissioning and on-site training, we’ve been extremely impressed with their work — very professional and responsive.  Our previous system had nowhere near the production of the Rattunde solution and we are already working with this supplier on our next system.”

From the machine tool builder’s perspective, the same relationship is echoed about Siemens.  Alec Banish, vice-president at Rattunde, commented, “We were asking Siemens to do some fairly complex operations in motion control, including 13 total axes with an articulating gearbox, plus the conveyor and part articulations, spindles and servomotors.”  He further noted the scalloped motion of the ID/OD brushing with disc transfers all presented unique motion challenges for the control hardware and software alike.  “The Siemens servo technology automated our entire process in a totally controlled, high-precision manner, allowing customers such as Cosmos to process a wide variety of materials, dimensions, shapes and lengths with easy-to-manage presets.”  Banish concluded by saying, “The Siemens support is greatly enhanced by the remote monitoring capability of the Sinumerik CNC.  About 70 percent of our issues are resolved remotely, working between us and Siemens or directly with the customer’s plant personnel.”

Prior to the implementation of the Rattunde system, all the piece part work done at Cosmos required two or three saws, with the attendant fixturing, parts handling, logistics and labor costs.  These bottlenecks in production were eliminated by the fully automated and single operation processing of the tubes provided by the Rattunde system.  Four tubes are processed per cycle, with servo control of the entire bundle, as it moves through the saw, brush and loading zones on this fully integrated machine line.

Rattunde builds various production systems for tube and bar product manufacturers.

From a factory utilization perspective, the prior system at Cosmos ran in three shifts for six days, each week.  Today, with the Rattunde system on the floor, occupying a far smaller footprint, one shift per day working just five days produces the same output with far superior quality and virtually no rework, according to company sources.

Rattunde President Richard Stadler further comments on the power of the Siemens CNC and related motion control products.  “We’re using all ten channels and pushing the axis capability to some extreme limits, but have seen absolutely no problems in signal degradation or processing speeds.”  Stadler also observed the Sinumerik CNC program storage capabilities were quite impressive.  “All the operator needs to do is provide a size range indication onscreen and all the relevant programs appear for easy selection.  Repeatability is obviously critical for our customer, who often process dozens of shapes and sizes per shift.”

He recalled meeting the Cosmos team at FABTECH in 2009.  “They approached us with their scenario and it was right in our wheelhouse.  We did some test cuts and time/motion studies for them and the results were quite impressive, both to them and to us,” Stadler muses.

Rattunde operates facilities in Grand Rapids, Michigan as well as a service center in Burlington, Ontario to better serve their North American customer base.

Rattunde markets its tube and bar production systems to makers of precision parts.  Currently selling 60 percent automotive, the company’s systems produce airbag canisters, cam shaft cylinders, steering components, rack mounts, driveshafts, frame components, seating parts, headrests, shock absorber parts, door impact devices, luggage racks and a variety of axles.  In addition to the cut-off and brush deburring system detailed here, the company also supplies production systems to perform various types of secondary machining operations, including threading, facing, chamfering and ID turning.
