Danfoss Power Solutions uses the KELCH KENOVA set line H3

Horizontal tool presetting – versatile table layout

Following comprehensive advice by the system manufacturer KELCH GmbH, Danfoss Power Solutions II GmbH opted for a tool presetter KELCH KENOVA set line H3: a horizontal tool presetter with an innovative swivel table, which can be flexibly integrated into the company’s production. A KELCH “Trabant” series tool presetter was previously used for around 30 years in the production of components for hydraulic pipe connection systems.

The need for a new tool presetter arose at the Danfoss production site in Lohmar. The manufacturer produces steel and stainless steel cutting rings and connector pieces for pipe connection systems at this site. Danfoss uses various machines, including single-spindle automatics, multi-spindle automatics and also rotary transfer machines. The tool presetter used up to now was starting to show wear on the spindle and rotary table after three decades of use. Its computer technology was outdated and its use required a lot of manual work, among other things to set the crosshair.

Horizontal tool measurement with a swivel table

KELCH consultant Bastian Birkenfeld presented the latest tool presetters to the workforce and recommended continuing to use a horizontal unit for the company’s existing tools. To minimise the set-up times through the simultaneous setting-up of multiple adaptors, Danfoss ultimately opted for the KELCH KENOVA set line H3 model. The horizontal tool presetter provides for a versatile table layout with tool holders with diverse interfaces (VDI, HSK, PSC, Index etc.), manual spindle and customised fixings. The variant of the tool presetter with swivel table offers additional possibilities for equipping it with tool holders or spindles. The rectangular design of the swivel table enables adapters to be positioned from different directions.

Precision and durability

The compact tool presetter KENOVA set line H3 features a stable, durable grey cast iron body and, with measuring lengths of up to 420 (X) x 350 mm (Z), is a perfect fit for Danfoss tools. Moreover, the axes are conveniently adjusted by means of a pneumatically actuated quick adjustment mechanism, and there is also endless fine adjustment in both axes. The tool presetter boasts a CCD camera including various control and analysis programs, offering greater precision than the existing unit. It is also available with various software versions and can be extended as required in future.

Simple and fast operation

Danfoss used KELCH’s offer to test the manual variant of the KENOVA set line H3 free of charge for some time. The operation of the unit persuaded the employees from the outset. “The different adapters can be changed quickly and seamlessly, even if the employees come from different departments. Above all, its simple and fast operation, for instance by the automatic setting of the crosshair, and the intuitive, self-explanatory operation of the software convinced us from the start,” reports Production Manager Marvin Janzen.
