The machine has been designed to make a wide range of spiraled pieces starting with a simply sawn piece of practically endless length. The patented drive unit is of ingenious and simple conception and is the heart of the machine. The unit is driven by a gearmotor which permits selecting desired operating speed. A set of telescopic and therefore easily extended bushes, makes preparing the machine very fast. The two fitted heads permit making spiraled pieces with righthand or lefthand spirals while the pitch can be chosen by replacing the fitted rollers on the drive blocks. A drawing unit roughs the piece giving it a cylindrical section while the piece is shaped by two independent and tilting cutting units that can be adjusted lengthways and crossways. A special support, available in the various diameters, eliminates any vibrations or piece breakages even during machining of small diameters. Machine commissioning, operation and maintenance are simple operations and do not require skilled labor.
