Abstract
Apparatus for inductively heating and hardening diesel cam shaft lobes includes a table supporting an inductor for radial displacement relative to the lobe of a workpiece to be hardened and a master component having a lobe identical to that of the workpiece to be hardened and supported for rotation about an axis parallel to and laterally spaced from that of the workpiece. The master component and workpiece are rotated in synchronism, and a follower roll on the table engages the lobe of the master component to accurately maintain a desired air gap between the inductor and lobe of the workpiece during the hardening operation.
