In our grinding shop we mainly grind the spindle shafts and bearing flanges that we use in the motor spindles for our machines and the machines of the DVS group. These are made to very tight tolerances and run in small batches of 1-5 pieces. The backbone of the grinding shop is two UGrind machines on which hard turning and grinding can be performed. A special feature is the WMZ spindle head grinding machine, in which the spindle heads of all our motor spindles are ground for the best possible concentricity and axial runout in the assembled state.
We machine spindle shafts up to D 200 and L 800 and bearing flanges up to D 450 in our turning and grinding shop. We achieve concentricity, runout, flatness and parallelism of 0.002 - 0.005 mm.
