Abstract
A method of rough finishing a piston, including removing gates and sprues, while the piston is rotated at a relatively slow speed. A rotating milling cutter provided with a multiplicity of cutting elements is positioned relative to the rotating piston such that the cutting elements successively engage and remove stock (chips) from the surface of the rotating piston. The milling cutter is rotated sufficiently rapidly to produce enough surface speed to generate the heat necessary to render the chips molten. An apparatus for carrying out the method is also disclosed.
