Mazak Spindle Repair

First, we separate the spindle parts and clean them. We then run a thorough analysis to identify the reason for failure and inspect parts to determine their condition.

We perform a rigorous testing process that entails:

• Determining whether the drawbar pull force meets OEM specifications.
• Verifying that the sensors and encoders produce an accurate signal.
• Checking motor parts for electrical shorts and insulation issues.
• Assessing bushings, spacers, bore, caps, bearing journals, and other parts for wear and tear and damage.
• Measuring tool connection surfaces, the shaft, and housing to determine fit and size problems.

We service Mazak spindles by:

• Restoring the drawbar pull force with new seals/springs to improve machine tool safety and accuracy.
• Correcting pilot, taper, face, and other connection problems to facilitate proper tool seating.
• Returning parts to their original fit and size to ensure bearings fit correctly.
• Replacing worn parts or reverse engineering and manufacturing them in-house if they are unavailable.
• Improving surface finish and durability through chroming, laser cladding, and regrinding.

In the final phase, we reassemble the spindle and test the electrical parts to ensure they work correctly. We also precision balance the spindle in a controlled environment to verify smooth performance. 

Our team provides a report and certification of the tests and a warranty when returning the spindle.
