Abstract: A machine for cutting a moving object comprises a conveyor belt for carrying the object along an advancement direction at a line speed and comprises a driving and cutting unit configured to move in a cutting cycle according to a forward phase in order to perform the cutting of the moving object, and configured to move according to a return phase in order to return into the initial position of the cutting cycle. The cutting machine further comprises a processing unit configured to generate a driving signal for controlling the movement of the driving and cutting unit with an acceleration trend wherein the maximum absolute value of the acceleration within the return phase is smaller than the maximum absolute value of the acceleration within the forward phase.

Abstract: A cutting-off machine, comprising a cutting unit (2) being enabled to receive a tube (100) and to cut the tube (100) according to a plane transversal to a longitudinal axis (X) of the tube (100), movement means (8) enabled to grip stably a length (S) of cut tube (100) and move said length (S) away from the cutting unit (2) along a direction of advance (A) of the tube (100), and a cutting-off device (5) interposed between said cutting unit (2) and said movement means (8) and configured to realise cutting off of an inner welding seam (200) floating inside said tube (100).

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).
