ABSTRACT:
A method of cutting and finishing a cylinder bore surface yields a highly polished finish having substantially no tool marks. The method includes removing a first thickness of surface material using a diamond-tipped rough cutter disposed on a rotating milling tool head. A second thickness of material is then removed by a diamond-tipped finish cutter also disposed on the same rotating head. The finish cutter removes between 0.0015 to 0.002 inches of material, which corresponds to the majority of the material left in the compressive state after the rough cut step.
