Text version of the page

MAIN TECHNICAL DATA • Max. diameter of piece:275 mm • Max. diameter of thread: 225 mm. • Max. length of thread: 350 mm. • Max. helix angle: 20 º. • Pitch range to be ground: 1-300 mm. BASE • Amply sized perlitic cast iron with the internal ribs necessary to ensure good machine rigidity and vibration-free running. • Designed with large spaces for collecting coolant and a sloping outlet to facilitate coolant removal and machine cleaning. • Coolant flushing around the base to eliminate the accumulation of swarf. TABLE -"Z" AXIS • Table driven by digital type A.C. servo motor and precision ball screw. • Guides covered with antifriction blades to allow them appropriate lubrication and stick slip free stroke even at slow speeds. • Lubrication is carried out through independent circuit. • Stroke reading by high precision linear glass scale. • Max. stroke speed: 6.000 mm/min.
