GMN TS180X318 Spindle Repair

The GMN TS180X318 is a grease lubricated and belt driven grinding spindle that can run up to 1,000 rpm.



CHALLENGE

We received this GMN TS180X318 spindle with a complaint that the spindle had play in the bearings and it made noise. Upon evaluation of the spindle it was found that the inner bearing spacer had been manufactured larger than the outer shoulder of the housing causing the spindle bearings to have no preload. The V ring seal made very little contact. Once the seal wore it no longer made contact after a short period of operation. The front shaft journal was undersized by -12/-16 (ISO at +/-5). The shaft taper and face both had high run out.

 

SOLUTION

The following actions were performed on this GMN TS180X318 spindle:

  • Clean all parts of the spindle
  • Replace all bolts and o-rings
  • Replace bearings
  • Manufacture new spacers to increase pressure
  • Upgrade the v-ring seals to Viton
  • Kiss grind shaft taper and face
  • Grind-chrome plate-finish grind the front shaft journal

 

RESULT

After reassembly of all components, adjusting bearing preload, and undergoing break-in and testing procedures, this spindle passed our final quality inspection before being returned to our customer with a 1-year warranty.

DETAILED CAUSE OF FAILURE

  • GMN TS180X318 Spindle Repair

    Bearing failure from coolant contamination. This was caused by the poorly fitted seal.

  • GMN TS180X318 Spindle Repair

    Contamination in the housing from the bearing failure.

Both of the spindles that you repaired are on the machines and running great. We don’t have any spares for those grinders. We probably will not be purchasing a spare, as you have been able to turn around the repairs quickly and the price of a spare is cost prohibitive.

I am writing to thank Northland Tool for going the extra mile and saving my company from expensive machine downtime and expensive repairs. We have always sent our Chiron spindles for repair as a shaft with bearings. None of our previous rebuilders pointed out the bearing fretting or the fact that the housing in the machine was out of tolerance and causing premature failure to the spindles. After Northland fixed the housings the spindles have never sounded as good or run as well! Great job guys!

The detailed cause of failure reports and the expert technical advice that Northland Tool provides is bar none the best I have ever seen. We struggled to keep two of our large our milling spindles running for longer than 6 to 12 months. Northland Tools evaluation showed that the hydraulic nuts were not holding the assembly together causing premature spindle failure. We discussed this in detail and mutually decided to modify the spindle shaft to prevent this from occurring again. The first spindle we performed this on is still in the machine running like new after 3 years. That’s over three times the life of previous repairs and it’s still going strong. Easily over $40,000.00 of savings so far on that one machine and counting.

Your people go above and beyond the call of duty when it comes to spindle repair. When we had difficulty with the spindle installation and we were able to talk directly to a spindle technician that helped us troubleshoot the issue it helped us out of a bind. We have sent several spindles to you and have nothing but great things to say.

Thank you for your attention with my quick turn spindle repair. Your status updates allowed me to plan around machine downtime and I now know that you deliver on your promises. In the past other spindle repair vendors talked a big game and consistently failed to deliver. You not only delivered my spindle before the due date but you kept me informed throughout the entire repair process.
— Northland Customer
You performed a miracle with my BIG PLUS spindle. After crashing the spindle severely damaging the taper we found that a replacement spindle was not only cost prohibitive but had a long delivery. Your repair was a fraction of the cost of new and you never would know that the spindle was damaged to the extent it was.
