Minnesota CNC shop uses Heimatec speed increaser to up RPM and feed rate; significantly reduces cycle time on aluminum engraving application
Kurt Machining (Minneapolis, Minnesota) specializes in providing precision CNC machined parts, using state-of-the-art technologies and up to 5-axis machining. Since 1952, this 110,000 sq. ft. shop has provided its customers in a variety of high-quality demand markets with components and welded assemblies. These include aerospace, defense, semiconductor, energy, automotive and more. A very flexible shop, Kurt produces parts ranging from micron-sized semiconductor components to 2000 lb. workpieces for the defense sector.
On a recent project, where 5000 pieces of 6060 aluminum were to be engraved on a Hwacheon horizontal turning center, Kurt Engineering Manager, Shawn Eisenshank, had concerns over the cycle times. He turned to his local tooling distributor, Abrasive Specialists, Inc. (ASI) and their tooling partner, Platinum Tooling, for suggestions. Leigh Kinnan of ASI worked with the local Platinum Tooling representative, Cody Papenfus, to test run a Heimatec speed increaser, with the goal of increasing RPM on the machine and decrease part cycle time, with a documentation of the potential savings. After performing the calculations in consultation with Preben Hansen, president of Platinum Tooling and exclusive importer for Heimatec products in North America, it was determined a significant savings could be realized.
Detailing the application, ASI demonstrated that a 1:3 speeder, increased the spindle RPM enough that when coupled with the nearly 3X increase in the feed rate on the machine, would produce a significant improvement to the current machining cycle. Calculating the reduction in machining cost per part and factoring the cost of the speed increaser, it was determined the use of the Heimatec product onboard the Hwacheon turning center would result in a 9X cost saving for the customer, in the first year’s production run on this engraved aluminum component.
As Shawn Eisenshank notes, “This is one of those classic scenarios, where the theoretical has proven out in practice, as we’ve seen exactly the results ASI and Platinum Tooling proposed in their test calculations.”
Cody Papenfus of Hexis in Plymouth, Minnesota, who is the area rep for Platinum Tooling adds, “We say we put our expertise to work at the spindle of the machine and, in this case, that’s exactly what happened. The speed increaser performed as expected, the customer got the results promised and it was a win-win, for all. We serve our customers for the long haul and successes like this one are the big reason.”
Kurt Machining performs both vertical and horizontal milling and turning, complex assemblies and weldments, delivering with rapid lead times. CAD compatibility is offered for web-based communications and fully interactive manufacturing engagement for its customers. The company performs contract manufacturing in high quantity as well as prototyping for new designs. Kurt also performs impact extrusion, heat treating and cleanroom operations including ultrasonic cleaning of stainless steel and aluminum components and assemblies, with cleaning to Class 1000 with 100 protocol. The company is ISO 9001:2015 and AS9100D plus NADCAP Certified. Kurt Machining is quality certified by the U.S. Government to MIL-Q-9858 and MIL-I-45208.

The following interview was conducted with Platinum Tooling’s President, Preben Hansen, at the company’s headquarters in Prospect Heights, Illinois. Hansen discusses the beginnings of Platinum Tooling, the transition period, changes, product lines and the future.
When asked what motivated him to start the company, Hansen said that it was a natural progression and that “As we added additional machine tool accessory lines to our offering, it made sense to have a name that encompassed more than just Heimatec.” He added “In our industry, it is common to have one importer representing multiple product lines.” Hansen was very pleased with the transition from Heimatec Inc., to Platinum Tooling. “As always, our main concern is the customer; their understanding of our continued presence and new image in the marketplace was essential to our success.” Furthermore, he was grateful for the acceptance of their customers during this transition period.
Regarding future changes at Platinum Tooling, Hansen isn’t going to change his main goal: making sure customer needs are met. He explained “As always, I will continue to look for new products to complement our current product offering in an effort to satisfy the growing needs of our customers. Since the transition to Platinum Tooling, we have done our best to assure our customers that we will continue to promote and support the Heimatec tooling lines as we did in the past.” Hansen clarified by saying “Heimatec tooling will always be our core business. We have several other complimentary lines including Tecnicrafts collets & guide bushings for the Swiss market, Henninger spindle speed increasers for machining centers, AMF marking tools, cleaners, and radio sensors plus Suzuki IB spindle speeders for Swiss machines.”
As for custom tooling, Hansen assures customers that Platinum Tooling will continue offering this service. “Our current manufacturers are all excellent at engineering solutions for special applications.”
Lastly, Hansen expressed excitement about the future of Platinum Tooling, saying “We are eager to see how the company will grow and evolve.”

Platinum Tooling, the importer of live tools, angle heads, marking tools, Swiss tools and multiple spindle tools manufactured by various global suppliers, is now importing Henninger Speed Increasers for North America. The announcement was made by company president, Preben Hansen, at headquarters in Prospect Heights, Illinois, near Chicago.
Henninger is a manufacturer of specialized equipment and precision machine tool accessories. Spindle speeder types including mechanical, air and electric motor driven styles are all available.
These speed increasers help maximize productivity by achieving a higher spindle rpm that is required for certain applications in today’s marketplace. Small diameter tools require rpms that are sometimes not possible to reach with existing machine tools. In addition, they allow for less wear and tear on the machine’s spindle when it is not required to run at its maximum rpm.
Mechanical speeders are available with up to a 1:8 gear ratio and a maximum speed of 50,000 rpm. Air speeders can run continuously at up to 80,000 rpm and high frequency motor spindles can maintain up to 80,000 rpm with high torque, and have variable speed options.
Many of the speeders have automatic tool change capabilities and are modular in design to offer the customer greater flexibility.
Henninger also manufactures custom angle heads, live centers, face drivers, and live chucks. In addition, Henninger is the premier manufacturer for center grinding machines.
