Abstract

A machine for machining brake drums wherein the cutting tool is cyclically retracted axially on its rotating spindle at a rate corresponding to the axial feed rate of the spindle and then quickly advanced on the spindle to the same extent so that the tool marks on the machined surface comprise a series of circular, rather than helical, grooves with relatively short, axially inclined grooves connecting the successive circular grooves.
