Swiss-Type CNC Auto Lathe Gives Kansas Manufacturer Two Machines in One

Veteran-owned Natoma Corporation produces precision parts for the aerospace, energy, and medical industries, as well as the Department of Defense. The company's recent search for new equipment to lessen a heavy workload led them to Eurotech Elite, where they found a machine that can do double duty.

The geographic center of the United States, Kansas, is the home of Amelia Earhart, Pizza Hut, the helicopter, the rotary-dial telephone and the Natoma Corporation.

Natoma's vast facility of 70,000 square feet is run by a team with a personal commitment to understand, meet, and, whenever possible, exceed their customer's requirements.



Founded in 1982, Natoma is a precision CNC contract manufacturer with an over 70,000 square foot facility. Natoma has customers in many industries, including aerospace, medical, electronics, communication, energy and environmental.

In 2014 Natoma began to search for new machinery to help meet and exceed their customers' requirements.

The "want list" search for new equipment had several key items. They needed to alleviate the heavy workload from the swiss style machines as well as the mill turn style machines. In addition they wanted to increase their capacity for single set-up part completion.

Natoma's Shop Manager Brandon Peterson and Lathe Foremen Travis Chisham meet with Jake Stalder, Eurotech's lead setup tech, next to the new Polygim machine.



Initially, Natoma considered buying two machines: one swiss style and one mill turn style. But their search led them to the unique CNC hybrid screw machines offered by Eurotech that solved both requirements in one machine.

"Our search led us to Eurotech and their Polygim Zeit 42SLY model with 42mm bar capacity. This machine fit our needs perfectly as it could bridge a gap between the swiss style and mill turn style machines and alleviate the workload for both. With the addition of the proprietary B-axis feature, we greatly increased our capacity...we now have the ability to include parts with angled holes or milled features," said Brandon Peterson, Natoma's Shop Manager.

"We are dedicated to delivering defect-free products on time at the most competitive prices possible, so for the price point, looking at buying two different machines versus one, the Eurotech Polygim, the decision was easy.

"The Eurotech Polygim could accomplish everything we were looking for in two machines. Furthermore, this machine now gives us the capacity to run some swiss style parts without the need for ground bar stock with the interchangeability of the spindle/guide bushing or fixed collet," said Gail Boller, Natoma's Owner.

Natoma maintains ISO 9001:2008 and AS9100 certifications and strictly adheres to their standards.



Their equipment goal being achieved, Natoma is working on utilizing the Eurotech Polygim to its full capacity. "We are still learning about the capacity of this machine and are looking forward to the free training program Eurotech gives to their customers," said Peterson.

The Polygim machines can be set up to receive most major brand collets and guide bushings. The Zeit model comes in 25mm, 32mm or 42 mm turning diameter and with the proprietary, fully programmable B-axis on the main and sub spindle. The machine also comes with gang static and driven tooling, Y-axis, C-axes on main and sub-spindle and is available with up to 8 tools on the B-axis.
