Apparatus for grinding a workpiece

摘要

An improved apparatus for grinding a workpiece (W) includes a base (10) upon which a headstock (21) and a tailstock (23) are mounted to support a workpiece for rotation about axis (A). A carriage (300) is movable along the base. A light weight wheel slide (400) is mounted on the carriage and is movable toward and away from the workpiece. A grinding wheel (501) is rotatably supported on the wheel slide. In order to provide a solid support for the light weight wheel slide, the carriage has a plurality of guideways (901, 902, 903) which are enclosed by the carriage. The carriage extends throughout the length of the guideways and provides a solid support for the guideways.
