CNC Spindle Rebuild

What is a CNC Spindle Rebuild?

At Superior Spindle we provide precision CNC spindle rebuild, spindle replacement, remanufacturing and spindle repair. We also do spindle taper grinding. CNC stands for “computer numerical control” and it refers to machining processes aided by computers. The spindle is a key mechanical component of the CNC that is designed for rotary motion. As an integral part of the CNC machine, the spindle does a lot of the work and can take a beating. With over 100 years of experience, you can trust Superior Spindle service to repair or remanufacture your machine spindles getting you back to work.

What to Expect From a CNC Spindle Rebuild

Superior Spindle Service is a state-of-the-art spindle repair and remanufacturer. That’s all that we do, and we make it a point to be the best at high speed spindle repair. Here is an overview of how we rebuild, remanufacture and replace the spindles that keep your business running smoothly.

1. Inspect, Analyze and Document the Condition of the Spindle as It Was Received

Once the spindle is unpacked, it is subjected to a cleaning, inspection and analysis. At the completion of this process, a failure analysis and repair report is prepared. This report, complete with pictures and computer-generated analytical graphs, shows the damage that the spindle has sustained. It also includes a detailed list of what it will take to rebuild or repair the spindles. This list is the basis for the quote and estimated time to repair.

2. Acquire, Manufacture and Repair All Parts Required for Assembly.

Our in-house capabilities include:

  • Machining to tolerances of 1 micron.
  • Bearing repair.
  • Vibration analysis.
  • Spindle balancing.
  • Electronics analysis and repair.

3. Assemble the Spindle Components in a Class 10,000 HEPA Clean Room.

Any dirt that is introduced at assembly time could substantially shorten a spindle’s operating life. We virtually eliminate this problem by assembling each spindle in one of our two clean rooms.

4. Test the Spindle in a Run-in Test

Once the assembly is complete, the spindle undergoes a run-in test. In this step, the spindle is run the way you would run it on your equipment. It’s at this point that last minute fine-tuning and balancing would be performed.

5. Prepare a Final Report

This report describes the key metrics and operating characteristics of the spindle after it has been rebuilt. It should show your spindle to be as good as or better than new. It will carry the same warranty that it had when it was new.
