FIELD: electricity.
SUBSTANCE: device contains a built-in non-operating zone of the round cutting saws heating element connected to a power source, saw blade temperature sensor for measuring temperature in the area adjacent to the jagged edge of the saw blade and the sensor provisions of the notched edge of the saw blade. The device is provided with a control unit configured to generate a signal from a temperature sensor and a position sensor to turn on the power supply. The heating element is made in the form of inducing thermal explorer box that is at an angle to the plane of the saw blade along the radius angle with a vertex in the zone of dentate edge saws and zone widths of thermal fields through rotate it relative to the radius of the circular-saw blade.
EFFECT: ensuring the preservation of a stable form of balance of the saw blade when cutting without additional cooling.
