Heald Spindle Repair

Why Use Northland Tool?

Expedited Repairs

Due to our more extensive control of the rebuilding process, we are able to provide to you the quickest repair and delivery in the industry.

CUSTOMER SUPPORT

We assign dedicated customer representatives to your spindle who will be in constant communication with you throughout the repair process, providing status updates on a daily or even hourly basis if needed.

IN-HOUSE 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. This allows us to better control repair timelines and costs.

NO CHEAP PARTS

Many independent spindle rebuilders modify the lubrication delivery system to allow them to use cheaper bearings. Northland Tool & Electronics only uses bearings that have the same design and quality characteristics as the OEM originals.

ONE YEAR WARRANTY

We offer one of the most all-encompassing warranties in the industry. Our warranty ensures that proper workmanship and parts without defect will be used in the repairing or rebuilding of spindles. Read full warranty.

AUTHORIZED BIG PLUS REPAIR FACILITY

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.

Common Problems With Heald Spindles

From coolant contamination to bearing failure to crashes, Northland knows that there are a variety of issues that will affect the performance of your spindle-and we’re prepared to handle them all. However, the common problems associated with this brand are:

  • Worn shaft bearing journals and worn housing bearing bores: This is common because the spindle design is so good that they are still in use 10, 20 sometimes 30 years after being put in service. The spindles were sometimes rebuilt “in house” and had new bearings installed. Particular attention needs to be paid to the dimensional aspects of the bearing contact surfaces as fretting, contamination and normal wear can bring them outside of acceptable size tolerances causing poor spindle performance.
  • Pilot: Worn tooling, crashes, excessive loads and normal wear are some of the contributing factors to pilot damage. This can be easily repaired in our in house grinding department with our grind plate grind procedure.
  • Worn Treads: Over time the threads for the tooling and pulleys can wear down causing decreased holding power and in some cases run out. Northland Tool & Electronics has several different repair options for this from thread repair to replacement shafts.
  • Damaged Pulleys from Tool Change: We receive Heald spindles that have damage to the pulleys from the tool changing process. We have several options available to improve the tool change process.
  • Crashes: Yes it happens. When it does particular attention must be paid to the shaft tolerances. Pilots can be distorted, shafts bent and grind plate grinds may be necessary to bring the spindle back to proper operating condition.
  • Excessive belt tension: Excessive belt tension causes rear bearing failure in Heald spindles. As feed rates increase and materials change we find that some of our customers have increased the belt tension to avoid belt slippage. Be careful not to go to far as it will put increased tension on the rear set of spindle bearings that are not engineered to take large amounts of radial load.

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 
— Northland Customer
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.
— Northland Customer
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!
— Northland Customer
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.
— Northland Customer
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.
— Northland Customer

Downtime is money. We provide the fastest delivery in the industry.
