Abstract

PURPOSE: To make the contact surfaces of a center with a claw more difficult to be damaged than those of conventional ones, by causing line contact between the rear conical surface of the pressure contact claw for a lathe or the like and the oblique surface of a moving member.
CONSTITUTION: A center fith a with a claw 25, which is fitted in the spindle of a machine tool such as a lathe and a cylindrical grinder to support a work- piece, has a step 11 at the front end of a sliding fit hole 4. A moving member support plate 12 is put in pressure contact with the step 11. Positioning pins 31 are placed in contact with the front surfaces of slender holes 30 in the head of the center and with the rear surfaces of slender holes 30 of the shaft 21 of the center. When a moving member 19 is caused to move in the radial direction of the body of the center, moment which would rotate the claw 25 around its axis is not caused because the force acting from the oblique surface 20 of the moving member 19 to the rear conical surface 27 of the claw is oriented toward the axis of the center. For that reason, the tip of the claw 25 cannot be damaged. Since the rear conical surface 27 of the claw 25 and the oblique surface 20 of the moving member 19 are put in line contact with each other, the contact surfaces are more difficult to be damaged than those of conventional centers with claws.
