FIELD: working metals by cutting, bearing making industry branch. ^ SUBSTANCE: cam is divided by annular turning along its symmetry axis by two members whose symmetry axes coincide with axis of recess. In order to enhance accuracy of working, outer surface of said members designed for engaging with generatrices of inner recess having V-shaped profile is in the form of toroid of revolution whose radial section has contour of ovoid with symmetry axis coincided with axes of annular turnings of cam and recess. ^ EFFECT: improved accuracy of working with use of such chuck. ^ 5 cl, 5 dwg, 1 ex |
