One of the leading differences between Northland Tool and Electronics and our competition is our grinding department. While many other spindle rebuilders send their grinding work to outside vendors we have made the investment in the machinery and the technology required to keep this vital service under our control. If our incoming evaluation shows a bearing shoulder that is not true we can place it on one of several grinding machines and kiss grind it true. Other rebuilders do not have that option and may repair your spindle with out of spec parts.
We often use our grinders to evaluate shafts and housings for straightness and perpendicularity. This is not always possible to determine with the standard method of using V-blocks.
Of course the main role of the grinding department is to grind-plate-grind any surface we have deemed out of specification. The quality that they provide to our customers in this area is bar none the best that I have ever seen. When you are talking about holding micron tolerances on spindle parts our guys are the best in the business!
Our grinding/machining department supervisor was also our head technician for over a decade. This gives us a unique perspective on grind work as he knows exactly what can influence the performance of the spindle and he has trained all of his employees to look for any issues that may effect the spindle repair quality and longevity. He also works closely with the assembly team to share information and continue the teaching process. Not many of our competition have a team of people that work so closely together and have the amount of individual input we have regarding the repair process.
One of the most important steps in the rebuilding process is the breakdown and evaluation of the spindle. This is the phase where the cause of failure is determined. NTE pays particular attention to this function so we can help you identify problems early and work with you to find effective solutions. Have you ever had a problem spindle? Did your spindle run great for years but now it has inadequate performance after it has been serviced? More than likely something that is affecting its operation has been overlooked. NTE’s breakdown and evaluation process can help identify these problems before they wind up back in your machine and on your production floor.
Every customer is important to NTE. We have a professional sales and technical staff to assist you with your individual spindle needs. Our goal is to find solutions to your spindle problems. This may involve a conversation or on-site visit from one of our sales engineers to explore solutions to your machine problems.
NTE has comprehensive, in-house OD and ID grinding capabilities that are used specifically to bring parts back to OEM specifications. This allows NTE to maintain tolerances up to .00005” along with providing for shorter turnaround times and greater control over our repair processes.
When you receive your spindle back from NTE, not only will you get the highest quality spindle repair, you will also receive a detailed report that includes run-out measurements, temperature readings, vibration analysis, break-in procedures, and other pertinent information.
NTE has several unique and proprietary programs for customer support. You are provided with operational cost savings, extended spindle life, decreased machine down time, and, as a result, increased productivity. NTE goes far beyond repairing your spindle. Our support includes spindle care seminars, vibration analysis, lubrication system inspection and evaluation, contamination prevention analysis, cause of failure tracking, spindle upgrades, and much more. We provide comprehensive reports on what we have observed along with recommended corrective actions.
When is a warranty not a warranty? When it is not honored! Along with having one of the most all-encompassing warranties in the industry, NTE is proud of the integrity it applies to ensure that you, our customer, are completely satisfied with the service you have been provided.
To receive the maximum benefit from your BIG PLUS tooling your spindle must meet the same high quality standards you have come to expect from BIG PLUS. Northland Tool has worked closely with the engineers at BIG Kaiser to develop a repair program exclusively for your BIG PLUS spindles.

I really didn’t expect this; You guys really pulled it off! My many thanks to Sandy, Louis and your outstanding crew for helping us get back into production.
Lou all in all everything is running good. Just had a call from Sandy just the other day, its funny great minds think alike. 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 Debbie 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.
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.
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.
Catastrophic bearing failure was the main cause of this spindle malfunction
