ABSTRACT:
A grinding apparatus has a tool support radially offset from a workpiece axis, rotatable about a support axis radially offset from and substantially parallel to the workpiece axis, and having a forwardly axially directed front support face formed at the support axis with an axially forwardly projecting centering formation formed a forwardly convex and part-spherical end surface. An annular grinding tool centered on a tool axis has an annular axially forwardly directed grinding surface engaging the workpiece surface and an axially backwardly directed rear tool face axially confronting the front support face and formed centered on the tool axis with an axially backwardly open recess engaging the end surface of the projection and of part-spherical shape complementary to the projection end surface. This tool is spaced from and out of direct contact with the support except at the recess and projection end surface. The support is rotated about the support axis with the grinding surface engaging the workpiece surface and projecting radially outwardly past the workpiece surface. An elastically compressible rear body is directly engaged between the rear tool face and front support face offset from the formation and recess. The tool is pressed axially backward to compress the body between the rear tool face and front support face for limited rocking of the tool axis relative to the support axis.
