Hardinge T42 Four Pack

Our customer wanted to requalify his Hardinge T42 spindles to make sure he continued to hold the very tight tolerances required for his customers products. As this took all four machines down at once we rush repaired them with grinding work and hand carried the spindles back within days of receiving them.

Ball Cage Manufacture

Many spindle rebuilders do not have the equipment or skill to manufacture the ball cages that are essential for proper preload of the bearings. The practice of reusing ball cages is usually done because they have no other option. They have not invested in the machinery and skill sets needed to manufacture parts correctly. One of the more common failures we see from other rebuilders is a ball cage that no longer functions freely. This causes excessive preload to the bearing set as the spindle experiences thermal growth. That eventually causes premature bearing failure. Don’t get short changed on your next repair.

Spindle Actuator Repair

This is a drawbar actuator that the walls of the ID had been scored and allowed hydraulic fluid to seep around the seals and contaminate the spindle bearings causing premature bearing failure. We were able to rework the ID in our grinding department saving our customer several thousands of dollars.

Manufacturing Spindle Parts

Since you can’t go to the local parts store and buy a front spindle housing and the lead times from the OEM can be measured in months not days, if they will even sell you the part. We manufacture replacement parts here to keep you up and running. Northland Tool manufactured this part, with micron tolerances, in 4 days and had our customer up and running in less than 7 days.

Need Your Spindle’s Drawbar Re-Qualified?

Give us a call 800-774-6353. Performing a Grind Plate Grind to your drawbar shaft in most cases is a lower cost alternative than replacing it with new. Over time the belleville washers or coil springs can wear grooves in the drawbar shaft itself. This can cause poor tool retention force and difficulty getting full travel of the drawbar during tool changes.

Why You Should Use a Third Party Repair Specialist — Don’t Let the OEM Hold a Gun to Your Head

A consumer has essentially two options when searching for a spindle repair specialist — keep the job in-house with the original equipment manufacture (OEM) or entrust it with a third party company that specializes in custom spindle repair work.

Machine Tool Spindle Bearing Lubrication: What To Know

Spindle bearings must be properly lubricated to maintain a film of lubricant between the rolling elements and the bearing raceways. Without lubrication, the rolling elements will have direct contact with the raceways, and this will result in heat, race deterioration, rolling element deterioration, cage disintegration, and ultimately bearing/spindle failure. There are several methods of lubrication used for spindles.

What Is the Spindle Repair Process?

The anatomy and functionality of a spindle is complex. And as such, it takes true expertise to understand, troubleshoot, and repair spindles correctly. From the moment a spindle repair job hits the loading dock and repair line, a spindle repair company is entrusted with making the necessary adjustments and recommendations to ensure the spindle is returned in working order—and in some cases, in even better condition than before it ever showed sign of original malfunction. However, though a spindle repair company may see thousands of repairs in any given year, each spindle repair job is different and must be treated carefully.
