HOMAG / SKF 4-075-03-0615 Electrospindle Repair

At our service center, we had the opportunity to restore full functionality to a WEINIG spindle that arrived with a severely damaged HSK 63F taper. The failure was so critical that it prevented tool release — the tool got jammed in the taper, and all disassembly attempts were unsuccessful.

The HSD ES 919 electrospindle was delivered to our service center with urgent need for repair due to bearing system failure and damaged sensors. The entire regeneration process, including disassembly and reassembly at the client’s site, took only 3 days. This fast turnaround was possible thanks to a pre-prepared rotating unit – a solution that minimizes machine downtime.

Neglecting the early signs of spindle wear can lead to very costly consequences. One of our clients experienced this firsthand when they contacted us with a spindle issue in a MAZAK NEXUS 510C-II machining center. If you want to avoid similar problems, read on to see the full spindle repair process and what caused the serious failure.

Our service received the HITECO QX-2 11/12 24 63F NC electrospindle, used in a five-axis CNC machining center. The unit, operating at 24,000 rpm with an HSK63F taper, showed signs of instability and system communication errors that made further operation impossible.

Repairing the KENTURN KC1508H spindle is a key process aimed at restoring its full operational performance. As part of our comprehensive service, we handle disassembly, repair, and reinstallation of the spindle into the customer’s machine. Each stage is carried out in accordance with the highest precision standards, ensuring long-lasting durability and reliable spindle performance.

The HSD ES 779L electrospindle, operating in a 5-axis FANUM machining center, was delivered to our service.
