Functional surface and symmetry are important in spherical superfinishing for tightness and high stress.

Ball machining

Superfinishing of spherical components

Spherical plain bearings and spherical components are used in diverse areas: they are installed in a wide variety of ways in the aerospace industry as well as in the automotive and agricultural industries. In all areas, however, these parts are subject to the highest quality requirements, as they must function perfectly despite high loads.

Precise machining and production are therefore imperative. In addition, long-term process reliability and low cycle times are of utmost importance for the cost-efficient production of the required quantities in constantly growing industrial sectors.


Machining of spherical plain bearings
with robotic feeding

Based on our decades of experience in superfinishing and the automation of manufacturing processes, our solutions meet these demands with precision.

In cooperation with our customers, we develop systems that meet any specific requirements.

In this way, maximum accuracy and consistent surface quality are achieved, even for individual components, with low unit costs.
