Abstract
PURPOSE: To completely correct the grinding end position of a keyway on a workpiece upon grinding of the workpiece with an abrasive by employing a stopper having an oblique surface formed in a forward direction to move forwardly a grinder unit moving downwardly.
CONSTITUTION: A worm gear 27 is fixed to the shaft 26 of a ratchet mechanism. A chain sprocket 31 is coupled with a worm wheel 28 engaged with the gear 27. A bolt 29 is engaged with the female threads at the center of the sprocket 31. The heat of the bolt 29 is fixed to a top plate 30. The bolt 29 is elevationally moved through threading operation upon rotation of the sprocket 31. Thus, the top plate 30 is lowered in parallel with the moving table 21. As the grinder unit is lowered, the operating position of a limit switch is moved forwardly along the inclined surface of the stopper 34 to move the grinder unit in predetermined distance forwardly. Thus, it can completely correct the grinding end position upon grinding of the workpiece with the abrasive.
