Abstract
A brake lathe for machining both brake drums and brake rotors wherein the tool carriage assembly is pivotable through an arc of about 90.degree. thereby allowing the tool carriage to engage the friction surfaces of either a brake drum or rotor on a fixed spindle. In the drum machining position, the tool carriage assembly is approximately parallel to the axis of the spindle and when in the disc machining position the tool carriage assembly is approximately perpendicular to the axis of the spindle. The lathe further includes alignment means to assure proper alignment of the tool carriage assembly with the spindle, and release means to remove the tool carriage assembly from the remainder of the lathe for service.
