Before each delivery, the repaired spindle is subjected to an extensive test run of approx. 8 hours. The star-up cycle of the bearings is carried out and the residual vibration is measured at maximum speed. Should it be necessary, the spindle – according to DIN-ISO 1940 – can be re-balanced, so that only a small residual imbalance remains. The spindles are tested by us depending on the spindle mounting position in the machine: horizontal or vertical! Nothing is left to chance.

Of course, all functions and parameters are monitored and measured during the final check. The measurement results are electronically documented and archived. For each spindle, an individual, detailed test protocol is created. It will be handed out to the customer. Deuschle is DIN EN ISO 9001: 2015 and DIN EN ISO 14001: 2015 certified.
