Abstract

PURPOSE:To prevent a workpiece from running out by providing a spherical bearing means allowing the whole body to oscillate around an inner ring section so as to enable jaws to cut into the workpiece uniformly in the case of the run out of a workpiece end face. CONSTITUTION:A spherical bearing body id composed of an inner ring 34 sliding on an are shaped contact surface and outer ring 35 being doublecut. The outer ring is fitted into the notch of the front end section of a spherical bearing bracket 18 holding the inner ring 34. Jaw bodies 38 for holding a workpiece are held in a body by the inner ring 34 and are provided with a tooth section K surrounding a center 13 made of cemented carbide in the center section. The jaw bodies 38 can be slidden freely by the spherical bearing body and cut into the workpiece uniformly in the case of the run of a workpiece end face preventing the workpiece from bending. This leads to the improvement of machining accuracy.
