Repair procedure

Repair procedure

  • Running an inspection on received spindles is able to reduce repair costs, and also help us know how to approach the servicing process. First of all, run-out, axial clearance, clamping power and electrical tests are performed. This is followed by more detailed and exact analysis.

  • Detailed analyses are performed while taking photos on every step, and obtaining precise measurements for all vital parts of the spindle. This shows exactly where the parts are damaged. Spindle failure cause and repair cost is estimated. With the data gathered, we can suggest technical advice for better using the spindle. e.g. Suggestions about improving the clamping system, using better quality of cooling water, using additive for anti-bacteria, etc.
  • Repair is performed after getting repair acceptance with cost estimate. So a faster acceptance means faster repair.

  • All spindle parts are cleaned perfectly with the best cleaning solutions. Damaged parts are refurbished. Sensitive parts like the shaft, bearing flange, etc. are cleaned with special solutions and devices. Other special parts like the oil lubrication system are cleaned with ultra-sonic cleaning device.

  • Parts that are needed are ordered or prepared. If needed, bearing seat for shaft taper (HSK, SK, BT, etc.) is coated and re-grinded like a new one. Grinded parts are grinded to a precise tolerance of 2μm!

  • All rotated parts are balanced by German balancing machines with ISO 1940 standard. This allows for smooth spindle running without any vibration. All balancing results are saved and filed.

  • The essence of spindle repair is seen during assembling. Measuring and adjustment for all parts must be performed by well-trained engineers. We have highly qualified engineers who are responsible and detail-oriented. Re-checking procedure is performed after finishing mechanical and electrical assembling, and before and after test-run.

  • Detailed grinding is sometimes needed even after very high precise assembling. In this case, run-out should have less than 2μm tolerance. This precise work removes the tool’s vibration which in turn elongates spindle life.

  • Every spindle must have a final test-run for more than 8 hours. Temperature, vibration, and run-out are measured and improved with our sensor system. Final inspection is performed and every spindle has its own test report. Every spindle that we have ever serviced has its own record. If we get the same spindle later, a faster and more efficient repair is possible because of the records.
  • Together with the final test report, we deliver spindle to customer as good as new.
