Abstract
An internal grinding method for grinding an inner surface of a work having a straight line generatrix shape while performing an in-process inner-diameter size measurement intermittently through oscillation synchronized between a grindstone and a measurer; wherein a circumferential surface of the grindstone is trued into a shape inclined with respect to a moving direction of a X-axis slide table moving forward/backward relative to the work so that normal grinding force when the X-axis slide table moves backward is reduced, while the work is supported with inclination with respect to the moving direction of the X-axis slide table so that the X-axis slide table is oscillated in the moving direction.
