Abstract

PURPOSE: To chamfer the end of steel bar efficiently, on chamfering an end of steel bar in the manufacturing line of engine valves, carrying steel bar fitted into the lead groove of screw shaft to the hand drum shaped grinding stone under a pressure.
CONSTITUTION: Steel bar 16 fitted into the lead groove of plural screw shafts 15 to rotate simultaneously is carried to the direction at right angle to the direction of the shaft, controlling movement to the direction of the shaft by stopper guide 17. Pushing steel bar 16 carried one after another by a keep plate 18 made of elastic material from above, one end of steel bar 16 is allowed to contact with the hand drum shaped grinding stone 20, the end of its is chamfered in curved surface. In this case, steel bar 16 to jump out due to grinding force is prevented by pushing force of keep plate 18.
