ABSTRACT:
The method of grinding the tapered bore of a rotary spindle, to true the bore while the spindle rotates about a spindle axis, the steps that include providing structure including a master plate having a surface facing the bore, the surface having a predetermined boundary to define a center; providing an angled slide on the structure, the slide being movable endwise relative to the structure and at a predetermined angle to the spindle axis, the angle corresponding to the spindle bore taper; providing a rotary grinder on the angled slide to be movable endwise therewith while the grinder rotates; adjusting the structure to bring the master plate surface into perpendicularity to the axis and to bring the center into coincidence with the axis, and; operating the grinder to grind the tapered bore as the spindle is rotated and as the angled slide is moved endwise.
