The material being processed remains stationary on the cutting table while the cutting head moves in the X, Y and Z axes. This high-precision three-axis drive system consists of a double-speed Z-axis recirculating bearing screw, the helical rack-and-pinion system and the pinion slide on the X and Y axes. The result is faster workpiece machining with a quieter and smoother drive system. In combination with the guideways, both motion accuracy and positioning speeds offer outstanding performance.
