Northland Tool & Electronics has several customers with large Shigiya machine installations. We provide service to their spindles reducing costly machine downtime. Spare parts, such as hydrostatic bearings, are machined and ground to exacting specifications in our facility. We test run every Shigiya spindle on our specialized test stands and put them through a rigorous QC inspection before shipment back to our customers.

Upon arrival, every spindle is logged into our production tracking software system. Any issues associated with incoming condition as related to transit are noted.[...]

The spindles are prioritized and moved to either the disassembly technicians or to the spindle run-up room, depending on the circumstances. Our techs carefully break down the spindle into its component parts while meticulously noting their general condition as well as specific damage to them. They also photograph the process and perform a full dimensional inspection to identify excessive wear which may help identify the cause of failure.

Once the initial disassembly and evaluation are completed, the spindle is given a second look by our production manager who reviews & completes the evaluation. He will identify the mode of failure and all pertinent issues, as well as recommended corrective actions. Many evaluations are not complete until the production manager consults with the head of our grinding & machining department. We often have recommendations for additional steps the customer can take to prevent premature spindle failure in the future. We call on our 30 plus years of experience rebuilding spindles to come to these conclusions.

After our purchasing department sources all replacement part costs & lead times, the quote is generated, given a final check and communicated to the customer for approval. Once we have received the approval, production is scheduled and parts are ordered. All spindle parts are carefully cleaned and any grinding or machining operations are completed. Only when all components are available and qualified does the spindle proceed to our spindle assembly technicians. These highly trained professionals assemble all the spindle components and then perform a rigorous break-in process which may include dynamic balancing as well as thermal & vibration analysis depending on the type of spindle. After a final quality control check is performed, the spindle is given back to our shipping department, carefully boxed to minimize the possibility of in-transit damage and shipped back to you, our customer.

Its great not to be sending spindles out on a regular basis since you addressed my problems, but I know they will still be coming sooner or later. Never a problem when we get them back , run better than new. Hope everything is ok there. Please tell everyone there that we here appreciate everything that you do to keep us up and running and the quick turnarounds. Have delt with the rest now deal with the best. Have a great week end and up and coming holiday.

Thank you NTE just received spindle today and WOW ! what a nice job. Can’t wait to use it. Thank the Northland team for us for a job well done 

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.
— Northland Customer
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.
