Professional Overhaul, Bearing Replacement, and Taper Repair
The photo shows a spindle from a Mazak HT5000 machining center, reaching a rotational speed of 12,000 rpm. This high-performance spindle is used in advanced precision machining applications that demand maximum accuracy, rigidity, and stability.
The presented spindle comes from a Lithuanian manufacturing facility, which entrusted FUMAK with a complete service and regeneration. This is yet another proof that Polish precision and FUMAK’s expertise are recognized and appreciated not only in Poland but throughout Europe.
Mazak Spindle Bearing Replacement – Precision and Durability
During the regeneration process, a complete bearing replacement was performed using high-grade precision bearings from reputable manufacturers.
The process included:
- disassembly and thorough cleaning of the housing and drive components,
- measurement of raceways, bores, and spindle shaft wear,
- installation of new bearings with factory-specified clearances and torque values,
- dynamic rotor balancing to accuracy class G1.0,
- final high-speed testing and temperature monitoring.
As a result, the spindle regains full operational performance, smooth running, and durability comparable to a brand-new unit.
Spindle Taper Reconditioning – Perfect Tool Clamping Accuracy
In many cases, poor machining quality results not only from worn bearings but also from taper runout or wear. At FUMAK, we perform Mazak spindle taper reconditioning, restoring its original geometry and coaxial alignment with the shaft.
Our process includes:
- precision grinding of HSK / BT / ISO tapers,
- coaxiality inspection on precision measuring systems,
- runout and ovality testing,
- restoring parameters according to OEM standards.
Through taper regeneration, we achieve perfect tool clamping, ensuring higher machining accuracy and extending the spindle’s overall service life.
