Vibration Reduction for Machine and Process Optimization in Machine Tool Manufacturing

Vibrations reduce productivity and quality

For any machine tool or production machine, the absolute goal is to achieve the highest possible output of products of impeccable quality. However, vibrations that occur during the production process usually counteract this goal. This becomes particularly problematic if such vibrations are not detected until commissioning or during operation. After all, no one can afford reduced production output or a vibration-related machine failure these days.

We calm your machines

Wölfel has been working for the mechanical engineering industry for several decades. With measurement, analysis and calculation, we have successfully supported machine manufacturers and operators in troubleshooting vibration-based problems in countless projects.

Our service portfolio in the field of machine tools:

Regenerative chatter limits the productivity of high-speed cutting processes, especially in case of milling of aluminium components for the aircraft industry.  Productivity is defined by MRR (Material Removal Rate) in liters of chips per minute. Chatter is caused by system and process instabilities, which can be avoided by applying specific damping. As passive damping methods have proved to be insufficient, Wölfel has developed a HSC milling spindle with active damping through piezo-actuators, in cooperation with an industrial partner, namely WEISS Spindeltechnologie GmbH.

The results of this technology realized by Wölfel for the first time are convincing: An increase of 50 % of the MRR - and thus of the productivity - was proven in the milling test.
