Precision hard turning is a key production process in the machine tool bearings unit at myonic GmbH in Leutkirch im Allgäu/Germany. Pieces are directly turned to the final dimension with extremely tight tolerances in the micron range. Using a probe solution from Blum-Novotest, key workpiece dimensions are now measured in-process, while still clamped. The result: greater measuring accuracy, improved manufacturing process, shorter cycle times.

myonic’s machine tool bearing activities are concentrated at a fully air-conditioned facility in Leutkirch, Germany. “The high-precision roller bearings are employed, for example, in rotary and swivel tables, milling heads and swivel spindles in machine tools,” explains Christoph Sauter, who, as Production Manager, is responsible for the manufacture of these precision bearings. “The bearings are double-direction, screw-on and installation-ready precision bearing units and part of the AXRY bearing range at myonic.” The axial-radial-bearings consist of three rings: inner ring, outer ring and axial washer. Additional components include the cylindrical rollers, axial and radial cages, lubricants and retaining screws that hold the assembled bearing together. The rings are made of chromium steel, which has proven highly successful in bearing rings and rolling elements and which is hard machined at myonic exclusively on turning centres.
