Running this spindle too long caused deformed ball bearings and damage to the outer race Damage to the outer race is consistent with prolonged operation after spindle exhibited initial signs of needin…
When a cylindrical surface, such as the OD of a shaft or the ID of a tooling taper, becomes worn or damaged, we use a process referred to as grind-plate-grind (GPG) to restore dimensions to original O…
How small is a micron, and why do we work in such a small scale? Precision is defined as the quality, condition, or fact of being exact and accurate.
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.
Many spindle rebuilders do not have the equipment or skill to manufacture the ball cages that are essential for proper preload of the bearings.
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.
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.
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.
We work closely with machine tool manufactures to keep up with the newest technology being used in today’s spindles.
