摘要
The cutting machine according to the invention comprises a frame (11) supporting at one end (11.1) a drive unit (12) with a stationary drive pulley (12.1) turned by a motor/gearbox assembly (12.2). Two idle deflection pulleys (13) are able to travel along respective straight rails (14) fixed to the frame (11). Each deflection pulley (13) is mounted on its own motorized carriage (13.1), which is able to move along the corresponding rail (14). To make the cut, the frame (11) is placed with the drive unit (12) in a proximal position to the material to be cut. A diamond wire (17) is introduced into holes specially made in the material and is formed into an endless loop, running it partly around the drive pulley (12.1), and deflecting it around the deflection pulleys (13), while correct tension is applied to it; the motor/gearbox assembly (12.2) is then turned, and with it the drive pulley (12.1), which sets the diamond wire (17) running, which wire, as it cuts its way through the material, tends to slacken, but is maintained at tension by moving at least one of the deflection pulleys (13) in such a way as to take up the excess length of wire.
