Wear of tool tapers, and damage of tool tapers
With thousands of tool changes, high torque usage and heavy radial loads, a spindle taper will wear to a bell mouth condition. This results in less contact between the toolholder and spindle ID taper. This can cause tool chatter, tool run out, poor machine performance and repeatability. Occasionally, an ID taper is damaged from a escaping toolholder. The raised portion of a gouge causes serous tool run out. These worn and damaged conditions can usually be corrected with a light grinding of the spindle taper.
Benefits of Spindle Taper Grinding on the Machine
On site spindle taper grinding on the machine is a cost effective way of improving the accuracy of your machine by repairing damaged or worn tool seats. This is done on the machine with respect to its geometrical condition.
The process requires an average of eight hours to complete and the taper conformity is checked by using a certified plug gage and test mandrel.
Through this process, removal and reassembly of the spindle is eliminated, thus providing considerable savings in machine down time and cost.
Hardened Spindle Taper Inserts to replace severely damaged machine spindle tapers
Occasionally machine spindle tapers become so severely damaged that regrinding the taper is insufficient to return the taper to usefulness. We can build a hardened insert to adapt to the end of the spindle so that the spindle is again useable as originally intended.

If you have an issue with a spindle taper, and the rest of the spindle seems good, contact us by phone, fax, mail, email or form below, and we’ll be pleased to help.
Keep in mind that the most common reason for dropping a toolholder is loss of drawbar force. To catch the fact that any of your drawbars have lost drawbar force you need to check the drawbar regularly – Spindle Drawbar Force Gage
If other areas of the spindle seem worn or noisy – bearings, motor, we do offer complete spindle repair service Spindle Repair & Rebuild
