SPINDLE TAPER GRINDING

Our mobile spindle service company performs spindle taper grinding to restore, repair and service machine tool spindle condition. The range of services include:

  • Mobile, on-site, in-plant machine spindle taper grinding or regrinding service for worn, damaged, crashed and wrecked spindles with 40, 50, 60, CAT40, CAT50, CAT60 tapers and larger, including Big Plus
  • Conventional, NC and CNC spindle taper grind, regrind, grinding, regrinding of worn, damaged, crashed and wrecked spindles in mobile, in-plant, on-site locations

On site spindle taper grinding 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.

Wear 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 ID taper. This can cause tool chatter, tool run out, poor machine performance and repeatability. Occasionally, a 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.
