摘要： A grinding machine comprises a base, a wheelhead (10) with grinding wheel (12) and wheel drive mounted thereon, a workholder (22,23,36) and drive means for rotating a workpiece mounted therein about at least one axis (24), workholder drive means for moving the workholder and therefore a workpiece carried therein relative to the machine base, wheelhead drive means for moving the wheelhead relative to the machine base, and a programmable computer base control system (46) for independently controlling the drives to perform a grinding operation by engaging the wheel with the workpiece. The way in which a workpiece is ground is determined by the control system in that the wheelhead is movable along two orthogonal X and Z linear axes in a first plane in which movement along the X axis moves the wheel towards or away from the workholder, and the workholder is rotatable about a C axis which is parallel to and in the same plane as the axis (18) of rotation of the wheel, the common plane being coincident with or parallel to the said first plane, and during engagement between wheel and workpiece the control system controls the rotational movement of the workpiece about the C axis and the movement of the wheelhead along the X and Z axes, so as to determine how the workpiece is to be ground. After grinding is completed the control system is programmed to move the wheelhead along at least one of the X and Z axes to move the wheel into engagement with a wheel-dressing tool. The system may be programmed to grind a slot in an end face of the workpiece.
