DEEPENING KNOWLEDGE, SHARING EXPERIENCE
Schunk Carbon Technology in Bad Goisern, Austria

Our visit takes us to the toolmaking department at Schunk Carbon Technology GmbH in Bad Goisern, Austria. The company joined the TNC Club way back in 2018, and enjoys its Premium membership. The TNC Club itself is now celebrating ten years of bringing the HEIDENHAIN community together.

ADDED VALUE THROUGH TNC CLUB PREMIUM MEMBERSHIP

Christoph Schiendorfer and his team make active and regular use of the benefits offered by TNC Club Premium membership. The annual visit from regional TNC Club application expert Michael Wartbichler provides an opportunity to learn about software innovations and deepen their knowledge of specific control functions. In addition, employees regularly participate in regional user training events. Alongside
technical presentations, the opportunity to exchange experiences and practical insights with fellow users is a particularly valuable part of these events. 

TOOLMAKERS ENSURE HIGH MACHINE AVAILABILITY

With a team of 18 employees, the toolmaking department plays a key role at the Bad Goisern site. Whether producing tools at short notice or manufacturing spare parts for production equipment, its primary objective is to keep downtime to an absolute minimum. Since the production machines used at the facility are designed and built in-house, the toolmaking department is also responsible for creating numerous prototypes. Programming work is split roughly evenly between programming directly at the machine and programming via the CAM system or an external TNC programming station.

PROVEN TECHNOLOGY WITH IMPRESSIVE LONGEVITY

The toolmaking department brings together two generations, both of people and of machine technology. The HEIDENHAIN controls in use range from a TNC 355 dating back to 1990 to the modern TNC7, which has
been in operation since 2024. Hubert Mitterhauser has been with the company since 1989 and has operated a HERMLE UWF 900 equipped with a TNC 355 since 1990. In more than three decades of service, only the monitor has had to be replaced. To this day, both the machine and the control continue to operate reliably and are used almost every day. Even this control, introduced in 1987, still provides all the functionality required for repairing production tooling and manufacturing prototypes for which no CAD model exists, thanks to features such as graphic program preview and integrated cycles. The machine’s open design offers another advantage: long aluminum profiles that are often difficult or impossible to clamp in enclosed machines can be machined here without difficulty.

THE PATH TO 5-AXIS MACHINING
As the need for machining multiple sides of a workpiece continued to grow, 5-axis machining became an increasingly important topic. To evaluate its benefits and economic viability in the toolmaking department, the company initially opted for a used machine equipped with an iTNC 530, providing a cost-effective entry into the technology. Two years ago, the company also invested in a new machine featuring a TNC7, becoming the first HERMLE customer in Austria to operate a machine with the new control. The transition to the new generation of controls went smoothly. Following initial setup and OEM training, the annual visit from the TNC Club application expert was used to further deepen the team’s knowledge and accelerate the familiarization process.

OCM CYCLES DRIVE PRODUCTIVITY
Toolmaker Fabian Schweizer works primarily on the TNC7. The OCM cycles for roughing and finishing, including the integrated cutting data calculator, are his personal highlight. The calculator assists users in determining optimal machining parameters and significantly reduces the effort required for manual calculations.

Hubert Mitterhauser: “As a toolmaker producing prototypes, I like to stay close to the cutting action. That’s why I enjoy working directly at the machine.”

Schunk Carbon Technology in Bad Goisern

The company’s roots date back to 1946, when it was founded as Hoffmann & Co. Elektrokohle AG. It became part of the Schunk Group in 1999. Today, the Bad Goisern facility develops and manufactures carbon contact strips for power transmission in rail transportation, components for the automotive industry, and, increasingly, shaft grounding solutions designed to dissipate stray currents in e-mobility applications.
