Abstract

The universal range of tool bits for supporting optical glass during grinding, serve to fix the glass in position on a rotating spindle, are all of the same dimensions with the plan area only of the support head (10) varying, and are suitable for suction, fusion or adhesion type support heads. Each unit of the range has a short length of shaft or stock (2) with a flat (3) for locking in a hollow spindle end via a radial locking screw, and an enlarged disc plate (5) locating normally on the outer end of the shaft to form the support for the suction cup. The cup or support head can be oval or rectangular (10), and a specific adhesion head is relatively plastic and to a medium index curve, with a right annular support surface.
