GMN TSEV-100SDU Spindle Repair
There were a few things that needed repair on this spindle. The grease was washed out of the front bearings. The grippers were missing so we replaced those. A housing rod had bent threads and needed to be replaced. The HSK taper had 20 microns runout which we corrected with a grind chrome plate and regrind bringing it back to specs. The front nuts also needed to be repaired. This was all done, inspected by our quality control department and returned to the customer.

This spindle came from a customer that we have worked with extensively to develop a repair program that fits their needs. They have an inventory of spare spindles on hand but did not wish to carry the repair costs in their inventory. Together we decided that they would send in the spare spindle inventory and Northland Tool & Electronics will break down the spindles, provide a cause of failure and a repair price. Once the spindle is approved the spindle goes into our system to be repaired. Once the spindle is rebuilt it then goes onto our environmentally controlled storage room until the customer requires it. Our customer calls us when the spindle is needed and we ship and invoice it that same day.
However with this spindle the customer needed it back as soon as possible. We were able to quote and rebuild the spindle within 4 days. The customer was up and running within a week. We are always looking to help our customers out. This could be turning a spindle around within a week or holding a rebuilt spindle until it is required in their facility. Contact us if you have any special requirements with your spindle.

This spindle came to us and was needed back at the customers ASAP. We disassembled and inspected the spindle. All critical spindle components passed quality control inspections except the taper that had 4 microns of run out. Additionally, when we checked the customers tooling we found that it had 30 microns of run out. We contacted the customer and it was determined that the tooling would need a kiss grind.
We kiss ground the tooling, adjusted preload and balanced the spindle. Final quality control showed that the tooling taper now had 3 microns of run out, well within the acceptable range of our customer’s tolerances. The customer had his spindle back within 3 business days. We were able to perform such a quick turn around because we currently employee two certified technicians to run our precision Kellenberger grinders.
