Monitoring automated induction hardening. (technology trends).

Until lately shops had no way to monitor the accrues of induction surface hardening in real time. on the other hand a new process is changing that, flat avoiding testing where sample parts are wound and polished before measuring their hardness.

Robotron Corp., Southfield, Mich., has disentangleed the Robotron-Elotherm system for real-time measurement of workpiece quality during the induction-hardening proces With induction surface hardening individual first heats a workpiece with medium or high-frequency strength and then cools it at a controll rate. the two aspects of the process are well understood,
