が終わる。Next, the operation of this embodiment will be described. The initial setting for the workpiece W is about to be performed. The workpiece W is supported by both the centers 4 and 5, and the table 3 is positioned at the Z-axis direction position where the grinding end face of the flange portion of the workpiece 17 does not interfere with the left side of the filler 17 and is supplied to the turning actuator 18. The fluid pressure is switched and the feeler 17 is turned to the measurement position. Then, use the pulse handle or manual operation button on the NC operation panel to move the table 3 to the feeler side in the Z-axis direction.
When the grinding end surface is brought into contact with the contactor 7a of the filler and the table is further fed by a small amount, a voltage is output from the detector 16 in accordance with the displacement of the filler. If they are compared and match, the match signal
It is sent to the NC device, and the Z-axis position of the table at this time is stored in the storage unit in the NC device as the reference position a. The fluid pressure is then switched, the filler is lowered to the retracted position, and the workpiece is rotated. Then, the grindstone base 7 in the retracted position in the X-axis direction is moved toward the workpiece side in the X-axis direction by the pulse handle or the manual operation button so as to approach the workpiece, and the left side surface (second grinding surface) and outer periphery (first grinding surface) of the grindstone are moved. The workpiece W is positioned at the approach position facing the ground end surface of the workpiece W with a small gap corresponding to the variation in the outer diameter of the workpiece and the grinding allowance of the ground end surface. Then, the table is moved toward the grindstone side in the Z-axis direction and stopped at the position C where the grinding end surface of the workpiece and the left side surface of the grindstone contact each other. At this time, the coordinate values of the table Z-axis position b and the X-axis position C of the grindstone are stored, and the grindstone of the grindstone is calculated from the X-axis coordinate value of the retreat end of the grindstone and the X coordinate value at the contact point C in the NC device. The forward distance Xl is calculated, and Xl × Cosθ is further calculated to calculate the distance Zl between the left side surface of the grinding wheel at the retracted position and the Z-axis position b.
Calculate the distance between a and b from the Z-axis coordinate value of the b position, add the distance between the Z-axis positions a and b to this Zl, and calculate the distance from the left side surface of the grindstone at the retracted position to the work locator measurement end surface, that is, the reference position a. It is obtained, and this is stored as an offset value l. In this way, the initial setting is completed to measure the grinding end surface of the workpiece with the work locator.

開始される。Initially, when a new grindstone is attached, prior to the grinding process, the distance between the retracted end position of the dressed grindstone left side and the reference position a on the Z-axis is determined. It is constant unless changed. By storing 1 as an offset value before grinding, it is not necessary to change it until the rear grindstone is changed, and the subsequent dressing amount is automatically added to 1 in the NC device. The first product grinding is started by the cutting (cutting) feed of the wheel head 7, and when the predetermined outer diameter is reached, the wheel head 7 moves to the backward end position in the X-axis direction by the sizing signal of the direct sizing device (not shown). The rotation of the workpiece is stopped. In this way, when the grinding accuracy of the workpiece W that has been machined for the first time has passed the inspection, the filer 17 is automatically swung to the measurement position according to the program by pressing the machining start button from the second piece, and the table 3 is moved. The reference position a in the Z-axis direction of the table is stored by moving rightward in the Z-axis direction and the ground surface of the workpiece comes into contact with the contact of the filler 17. Next, when the filer rotates and the workpiece is rotated and the grindstone 7 moves toward the cutting feed start position along the X-axis at the rapid feed rate, the NC control synchronizes the table 3 and multiplies the X-axis movement amount by Cos θ. The left side in the Z-axis direction. When the grindstone base 7 is positioned at the cutting feed start position,
The table 3 that has moved synchronously is positioned at the left side position with respect to the reference position a in the Z-axis direction, and is automatically offset and positioned to the right side in the Z-axis direction by the offset value l obtained by initial setting. . In this state, the left side surface and the outer periphery of the grindstone 8 face the grinding end surface and the grinding outer diameter of the workpiece W with a small gap in consideration of the variation in the grinding allowance. Next, the table 3 maintains this Z-axis position,
Cutting feed in the X-axis direction is given to the grindstone base 7 to start grinding.
