Ultra precision grinding of spherical convex surfaces on

22/09/2003 The rotational grinding of spherical surface with cup wheel was first used by Taylor .By tilting the cup wheel to an angle α, and by properly positioned the cup wheel such that contact line runs through workpiece’s rotational axis (), a convex spherical surface with radius R can be generated, which is described as (1) R = D m-2 r sin α 2 sin α where r is the lip radius of the cup wheel, D

Spherical surface generation mechanism in the grinding of

01/04/2000 To produce ultraprecision ball bearings, it is necessary to clarify spherical surface generation mechanism in the grinding of balls. This paper is the first attempt to investigate the contact trace distribution on the ball surface, which is crucial to spherical surface generation. The kinematic analysis of the contact trace shows that the contact trace is a fixed circle on the ball surface and
