動装置。(1) A grinding wheel pivotally supported on a base, and a grinding wheel mounted on the base so as to be slidable in a direction perpendicular to the axis of the grinding wheel, and capable of being moved near and far with respect to the grinding wheel by an appropriate moving device. The workpiece is ground without center by sandwiching the workpiece between the grinding wheel and the adjusting wheel pivotally supported on the sliding bed, and rotating the grinding wheel and the adjusting wheel by an appropriate driving means. In the centerless grinding machine, a work discharge chute is supported on a sliding plate attached to the base so as to be able to slide parallel to the sliding bed, and one of the opposing parts between the sliding plate and the base; and a linear engagement member facing the moving direction of the sliding plate is provided on one of the opposing parts of the sliding plate and the sliding bed, and on the other of the opposing parts,
Centerless grinding characterized in that it is provided with an engaging/disengaging member that connects the opposing parts to each other by engaging with an arbitrary part of the engaging member, and an actuator that engages/disengages the engaging/disengaging member from the engaging member. A device for moving the chute for discharging workpieces on the board.

排出用シュートの移動装置の使用方法。(2) A method of using the device according to claim (1), in which the adjusting wheel is moved near and far with respect to the grinding wheel for supplying and discharging the workpiece, when the sliding plate and the base are engaged at the opposing portion. The sliding plate is fixed to the base and adjusted by engaging the engaging member and the engaging member with each other and separating the engaging member and the engaging member at the opposing portion of the sliding plate and the sliding bed. When moving the wheel toward the grinding wheel by the amount of diameter reduction due to modification of the grinding wheel, the engaging member and the engagement member at the opposing portion of the sliding plate and the base are separated, and the sliding plate and the sliding bed are separated. Use of a moving device for a chute for discharging a workpiece in a centerless grinding machine, characterized in that the sliding plate is moved integrally with the sliding bed by engaging the engaging member and the engaging/disengaging member in opposing parts of the machine. Method.
