ABSTRACT:
A spindle brake mechanism for a milling machine which includes a plurality of brake shoes that are pivotally mounted about the machine spindle. The brake shoes are pivoted for movement into and out of frictional braking contact with the machine spindle and are circumferentially encompassed by a freely rotatable ring which carries thereon a plurality of actuating members that associate with each of the brake shoes. At the completion of the work cycle, the driving force is removed from the spindle and the ring is rotated thus causing the actuating members to forcibly cam the brake shoes into contact with the spindle thus applying a frictional braking effect thereon.
