Induction tooth hardening with bend straightening and mechanical pinch roller straightening unit

The machine is fast and has an easy start up and change over. The air-cooled oscillator tubes make the generators high in efficiency and low in energy consumption. It has a high reproducibility due to accurate digital/analogue settings of power, speed and work coils.

Bend straightening unit
A section of the bench are hinged in such manner that the band can be bent over a high point to counteract camber effect during teeth hardening on the most narrow bands, typically 6-12mm width.

Mechanical pinch roller straightening unit
The second straightening device consists of a pair of rolls situated after the quench tank. The mechanical straightening unit are best suited to work within the band widths of 12-20 mm, thickness of 0.45-0.6 mm with TPI between 3-6 TPI.

Band feed system
The band feeder consists of two units, one acting as a feeder, the other as an adjustable brake to control the band tension. The system is designed for accurate speed and guiding and electromagnetic friction brake for optimal control of band tension.
