The calibrating spindles are mounted to a robust cast iron monolithic structure which practically eliminates vibrations generated when operating even during intensive work cycles.
A recirculating ball screw assembly positions the diamond plate guaranteeing constant precision and performance reliability. This system also automatically raises the spindle in the event the conveyor belt shuts down preventing the diamond tool from excessively machining the workpiece, and then when restarted the spindle automatically returns to its preset machining depth.
The machining depth for each spindle is visualised on a digital display with a precision to hundredths. To guarantee such highprecision machining encoders detect and monitor the position of the spindle rather than the ball screw assembly which moves the spindle.
The recirculating ball screw assembly system adopted for raising the spindle guarantees fast and precise spindle movements without wear, unlike conventional trapezoidal screw systems which in emergency conditions only allow for controlling vertical positioning of the spindle and do not raise and lower spindle.
Dynamically balanced large diameter and dimensioned diamond tools combined with high-powered motors, ensure high-speed machining performance. The diamond are fitted with a removable external crown that allows for quick diamond segment assembly and fitting.
