Abstract

A new principle and technology of point form grinding for quadratic surface flank of twist drill was investigated. It broke through the traditional straight-line generator grinding method for the conical and the spiral drills. The principle of implementation mechanism was given in the paper. The trueness and feasibility of the method had been approved in the experiments, and the quadratic surface twist drill such as hyperboloid, ellipsoid and hyperboloid-ellipsoid compound flank had been grinded on the mechanism.
