Brake lathe with display

摘要

A brake lathe includes a set of rotor cutting bits and a drum cutting bit. Each bit has associated therewith an encoder for measuring the displacement of the bit. The displacements as measured by the encoder are used by a controller to digitally determine various parameters such as absolute thickness of a rotor being lathed, the depth of cut into the rotor, absolute internal diameter of a drum being lathed, and the depth of cut into the drum. The lathe includes a display for displaying the values of the parameters. The lathe includes a calibration mode for calibration of either the rotor cutting or the drum cutting function of the lathe as desired.
