Induction tooth hardening with mechanical straightening of carbon band saw blades

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.

Inductors
The inductors are made of copper tubing and can be custom made for different pitches and band gauges. The inductors are interchangeable and can easily be replaced from one type to another.

Mechanical straightening device
The straightening device consists of a pair of rolls situated between the hardening and tempering inductors. The rolls are driven and are mechanically adjustable in height for different band widths.

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.
