Abstract
An improved brake drum and method for machining and balancing a brake drum are provided. The inner facing surface and the outer facing surface of the brake drum are machined. The inner and outer faces of the hub end of the brake drum are also machined. The machining is accomplished in a single operation that results in a radially balanced brake drum.
Claims10
A method of machining and balancing a brake drum comprising the steps of:
- providing a brake drum having a generally cylindrical body having a central radial axis and an open end and a hub end,
- the hub end comprising an inner facing surface and an outer facing surface,
- the brake drum body including an outer radial surface and an inner radial surface,
- the outer radial surface including a radial edge,
- holding the radial edge of the open end in a chuck assembly, machining the inner facing surface and outer facing surface of the hub end, and machining the outer radial surface and inner radial surface of the brake drum body in an operation to radially balance the brake drum about the central radial axis.

A method of machining and balancing a brake drum comprising the steps of:
- providing brake drum having a generally cylindrical body having a central radial axis and an open end and a hub end, the hub end comprising an inner facing surface and an outer facing surface,
- the brake drum body including an outer radial surface and an inner radial surface, holding the brake drum in a chuck assembly, machining the outer radial surface and inner radial surface of the brake drum body and machining the inner facing surface and outer facing surface of the hub end, in an operation to balance the brake drum about the central radial axis.
A brake drum comprising
- a generally cylindrical body having a central radial axis and an open end and a hub end, the hub end comprising an inner facing surface and an outer facing surface,
- the brake drum body including an outer radial surface and an inner radial surface,
- wherein substantially all of the inner facing surface and outer facing surface of the hub end and substantially all of the outer radial surface and inner radial surface of the brake drum body are machined in an operation while the brake drum is held in a chuck assembly,
- the brake drum being balanced about the central radial axis at the conclusion of the machining.
