Double cutting mode cut-off machine

Abstract

A cut-off machine comprising: an electric motor (2) arranged for rotatingly driving a cutting tool (10); a transmission (4) which is so structured as to transmit the rotary motion of the motor (2) to the cutting tool; a control module comprising an inverter, designed to allow adjustment of the rotational speed of the motor (2). The motor (2) is so structured as to impart, to the cutting tool, a first rotational speed suitable for performing a heating and friction-based cutoff of the material to be cut; the transmission (4) is provided with an at least two-speeds gearbox, which is so configured as to vary the speed transmitted to the tool between the first speed and second speed, the latter being lower than the first speed and suitable for performing a material removal cutoff (slow-speed saw cutoff).
