Grinding of the spindle head taper on CNC machines

The grinding angle is set automatically on our machine, which means that high repeatability is guaranteed. In doing so, the device relies on an optical encoder with an accuracy of ±1.5″ to ±3″-> with a repeatability of 0.001°. The device is controlled via an HMI (human machine interface) display and the processing is done by a PLC (programmable logic controller). Adjustments can be made to the stroke length during grinding, to the various feed speeds and rotational speeds and, if necessary, to the micro-adjustments of the grinding angle.

The device operator is able to use the device independently after relatively short training.

Repairing the geometry of a CNC machine’s taper can be performed in an extremely short time, which means significant savings for the machine owner.
