Abstract (en)
[origin: EP0270117A2] A lens grinding tool having a cylindrical shank and a radial shoulder is secured to the shaft of a motor for rapidly rotating the tool, by means of a drawbar extending the length of the shaft and threaded into an axial threaded bore in the cylindrical shank. The location of the tool is precisely fixed by means of ring-shaped shims adapted for placement about the cylindrical shank of the tool between the shoulder and either a mating surface on the shaft or intermediate means for securing the tool to the shaft.
