GREATER PRECISION & TRUER BORING

Grinding the spindle taper seat, in place, while the spindle is running in its own bearings, will true up any error in concentricity. Even new spindles can achieve better concentricity by grinding after assembly, eliminating the stack up of tolerance error. Out of round and erratic sizing of bores, are commonly caused by movement between tool and spindle.

INCREASED PRODUCTIVITY

Faster feed rates and spindle speeds can be achieved, as equal cutting pressure is distributed to all cutting edges of tool, by true running spindle and tool.

REDUCED TOOL CHATTER AND BETTER BLENDS

Renewing the spindle taper seat tolerances, by regrinding in place, insures a ridged connection between tool and spindle, eliminating chatter and rock caused by poor tool seating.

INCREASED CUTTER AND TOOL HOLDER LIFE

Your cutting tools will last longer. The spindle to tool concentricity allows the work load to be equally distributed among all the cutting edges of the tool, so no one edge is broken
