Röhm not only supplies multi-part clamping systems to manufacturers worldwide but also uses the technology extensively within its own production facilities to improve productivity, process reliability and quality. The experience gained feeds directly into the development of practical solutions for customers across a wide range of industries.

One example is at the company’s Dillingen plant, where the manually operated Duro M lathe chuck is manufactured. Used on conventional, horizontal and vertical turning and milling machines, as well as rotary tables and indexing units, the chuck is produced using specially developed multi-part clamping systems from Röhm’s own portfolio.

The objective was to reduce machining and auxiliary times while increasing machine utilisation. By introducing a self-designed four-station clamping fixture, machining time per part was cut by around 90 seconds, while loading, tool changes and pallet changes were significantly reduced. Overall, productivity increased by approximately 10%.

“We needed a power-actuated solution with higher accuracy, since the components are milled from a pre-turned blank with finished reference surfaces,” explains Magnus Strobel, production manager in Dillingen. “The specially developed four-station fixture enables secure, distortion-free clamping while allowing complete finish machining in just two setups.”

Röhm also employs multi-part clamping technology to manufacture the stepped jaws of the Duro M. An automated production cell, comprising a Chiron DZ 16 W twin-spindle machining centre, integrated industrial robot and custom eight-station clamping fixture, handles loading, machining and unloading with minimal operator intervention.

Looking ahead, Röhm plans to expand the concept further. “We’re currently planning to add power-operated centric grippers, enabling us to machine cubic parts using the same production principle in the future,” adds Strobel.
