Claims

[Claims for Utility Model Registration] A grinding wheel having a cylindrical grinding surface parallel to the spindle axis and a shoulder grinding surface orthogonal thereto on a grindstone head guided so as to be movable in a direction perpendicular to the spindle axis. A grindstone having a wheel mounted on the shaft, and represented by the position of the cylindrical grinding surface in the X-axis direction perpendicular to the main shaft axis, and the position of the shoulder grinding surface in the Z-axis direction parallel to the main shaft axis. It has first and second current position registers that respectively store the position coordinates of the grinding tip point of the wheel, and the distance between the grinding wheel head and the workpiece table is determined based on the contents of the first and second current position registers. In a numerically controlled grinding machine, the cylindrical grinding surface and the shoulder grinding surface of the grinding wheel can be corrected by a grinding wheel correction tool provided on the workpiece table by controlling relative movement, wherein the grinding wheel head and the workpiece table are controlled relative to each other. an original position return means for returning to the original position, a movement amount detection means for detecting the movement amount of the grindstone head and the workpiece table, and a register update means for updating the current position register according to the movement amount. After preparing and returning the grindstone head and the workpiece table to their original positions,
The first step when the grinding wheel head and workpiece table are moved until the cylindrical grinding surface and the shoulder grinding surface of the grinding wheel respectively abut the grinding wheel correction tool.
A numerically controlled grinding machine characterized by being provided with a grindstone correction tool coordinate setting means for storing the values of the second current position register and resetting each of the positions to "0" as the origin.
