DMG / Kessler motor spindle repair in 5 working days

Our mission

This week we were able to repair a Kessler motor spindle from a DMG system for a large automotive supplier within five working days, including a new stator, overhauled clamping system and reworked tool mounting.

In conjunction with our machine service for DMG systems, we were able to offer the customer full service, including the installation of the spindle and a completely overhauled spindle equivalent to a new spindle.
