    GMN TSEV-100SDU Spindle Repair

    5,000 RPM

    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.

    GMN  TSSV110 Spindle Repair

    42,000 rpm

    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.

    GMN TSSV120-60000-5  Spindle Repair

    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.

    Front bearing failure causing the inner race of the bearing to spin on the shaft.
    Northland Tool ground plate ground the front bearing journal to OEM specifications. We then rebuilt the spindle in our clean room and test ran it at speed. The spindle was trim balanced at 60,00 rpm and run on our test stand duplicating the machines set up as much as possible.

    Tool & Cutter grinding spindle
    This spindle had worn bearings and 3 to 4 microns of run out on the tapers. We are able to fix these spindles because we have our in house grinding department. The tooling interfaces need to meet micron tolerances to function properly. We have developed a process and the equipment needed to meet these tolerances.
    We repair all types of Walter Grinder spindles from older style to the newest release.

    Our customer has instituted a predictive maintenance program for their spindles at this facility. This spindles vibration characteristics exceeded the preset threshold during the last vibration testing route. Our customer pulled it from production and sent it to us for repair.
    Because the spindle was removed from service before it suffered catastrophic bearing failure it only needed a “straight” repair. The cost savings from the repairs alone will give our customer a return on their predictive maintenance investment in less than one year!

    Campbell Grinder Spindle
    This GMN spindle is used in a Campbell Grinder. Our incoming evaluation showed the bearings were contaminated with part coolant. We reviewed the different techniques we could used to help prevent contamination with our customer and decided on what would work best in their application. Years later this spindle is still running in the machine with no indication that contamination has entered the spindle.

    This spindle had run out in the taper and the front housing was fretted/over sized.
    We ground plate ground the front housing and were able to kiss grind the run out from the taper on our Kellenburger grinders. We then rebuilt the spindle, test ran and balanced it at speed.
