ABSTRACT:
A grinding machine wherein the grinding wheel has a profile consisting of recurrent identical sections, as considered in the axial direction of the grinding wheel. The profile of the grinding wheel is treated by a dressing tool whose profile is that of a worm and is complementary to the profile of the grinding wheel. The axial length of the dressing tool equals that of one section of the profile of the grinding wheel and the axes of the grinding wheel and dressing tool make an angle which matches the lead angle of the worm-like profile of the tool. A feed screw is used to move the dressing tool in parallelism with the axis of the grinding wheel at a rate such that axial displacement of the tool per revolution of its shaft equals the axial length of one section of the profile of the grinding wheel. The grinding wheel is used to convert blanks into toothed racks.
