A cam of a camshaft has its surface hardened by rotating the camshaft about its axis while maintaining a TIG torch at a fixed spacing from the surface, and while relatively axially reciprocating the torch and the camshaft so the torch heats the surface along an undulating path. The pitch or crest-to-crest spacing of this path is maintained constant for uniform hardening either by varying the angular rotation rate of the camshaft or by varying the axial reciprocation frequency between the camshaft and torch. The radial spacing of the portion of the surface being heated at a given instant from the axis is measured to control the rotation or reciprocation rate.
A method of surface-hardening an object having an axis and an eccentric surface, said method comprising the steps of: rotating said object about said axis at an angular speed rate; juxtaposing a torch-type heat source with and directing same radially at said surface; displacing said heat source radi
A method of surface-hardening an object having an axis and an eccentric surface, said method comprising the steps of: rotating said object about said axis at an angular speed rate; juxtaposing a torch-type heat source with and directing same radially at said surface; displacing said heat source radially of said axis relative to said eccentric surface during rotation thereof to hold said heat source at a substantially fixed radial distance from said surface; relatively axially reciprocating said heat source and said object during rotation thereof at a reciprocation rate so that said heat source heats said surface along an undulating path; and varying one of said rates in such a manner that the pitch of said path remains substantially constant.
