Method of and machine for reprofiling a railroad-car wheel |
摘要 |
A railroad-car wheel is rotated continuously about its central axis. A tool having three axially and radially spaced cutting portions is first displaced along the wheel so as to remove high spots at the inner and outer edges thereof by means of the two end cutting portions. Thereafter the tool is backed up and again axially displaced over the rotating wheel so that the cutting portions sequentially take more material off the workpiece constituted by the wheel and impart to it the desired profile in a single second pass.
