Abstract

PURPOSE: To improve the rectangular accuracy of the tip surface of a round steel bar by pressing the round steel bar of a plunger, etc., against a V-block and rotating a cup-shaped grinding wheel on the tip surface thereof.
CONSTITUTION: On the V-groove surfaces 11, 12 of a V-block (a), a finished round steel bar (b) is laid and pressed down from above with a small diameter roller 9. Under this pressure, the round steel bar (b) is rotated in the arrow mark direction. To the end surface 4 of the turning steel bar (b), the end rim surface 5 of a cut- shaped grinding wheel (d) is pressedly abutted and the grinding wheel (d) is rotated. By so doing, the accuracy of supporting the round steel bar (b) is improved and grinding is carried out by the relative revolution of the steel bar (b) and the grinding wheel (d), so that the rectangular accuracy of the tip surface can be improved.
