The New Generation System Of Vertical Machining Centers550

The base parts are made of high-strength cast iron and aged to ensure the stability of accuracy; X, Y, Z three direction feed using large pitch, high precision and high strength ball screw, feed speed is high; The servo motor is directly connected with the lead screw using the elastic coupling to ensure the positioning accuracy of the machine. The lead screw is pre-drawn structure, which greatly reduces the influence of thermal deformation on the positioning accuracy;
