    摘要： A method of manufacturing brake drums or the like and apparatus therefor that minimizes scrap rates by improving as-manufactured balance. In accordance with the disclosed method, the casting rim of the brake drum is located in a press by centering the drum relative to its outer surface. Locating holes are then accurately formed in the drum center by the press prior to machining of the drum inner surface. The subsequent machining operation on the drum inner surface is accomplished by locating the drum accurately via the locating holes formed in the press operation.

    摘要： A method of making a composite brake drum having an axially perforated sintered metal drum ring and a stamped steel mounting back attached to one end of the drum ring. The drum ring is compacted from ferrous powder in an annular cavity of a compacting press while a plurality of tapered core pins are disposed in circumferentially spaced relation in and extending axially through the cavity. The compact is stripped from the cavity and pins by movement of the compacting punches relative thereto. The compact is sintered to complete the drum ring and thereafter a stamped steel back is secured to the ring by arc welding a continuous welded seam between the ring and back.
