ABSTRACT:
Sizing apparatus for an internal grinder having an oscillation motor for oscillating a grinder wheel contacting the inner peripheral surface of an annular work piece, a sizing device to generate sizing signals for measuring the bore of the work piece, a measuring probe connected to the sizing device, a probe position sensor for sensing positions of the measuring probe in an axial direction of the bore of the work piece with reference to a rotation angle of a drive shaft of the oscillation motor, and a sizing signal sampler for sampling sizing signals when positions of the measuring probe are inside the bore of the work piece. The sizing apparatus for an internal grinder is capable of measuring the bore of the work piece during an oscillation machining despite the smallness of the bore and size in the axial direction of the work piece.
