Abstract
An apparatus for tempering the surfaces of mutually displaced cams of a cast-iron camshaft in which heat energy sources are movably disposed at a distance from each cam. The apparatus holds the camshaft to be tempered in a vertical orientation for rotation about its axis and the heat sources are positioned about the camshaft axis at relative angles of rotation equal to the relative angles of rotation of the corresponding cams so that the cams may be heated simultaneously and syncronously with the rotation of the camshaft.
