● the machine tool adopts the gantry fixed beam frame structure, which can maintain good rigidity and accuracy for a long time, with large torque and good dynamic characteristics. It fully absorbs the international advanced machine tool design concept according to the processing requirements. ● key parts, including bed, column, beam, saddle, ram and workhorse, are all made of high-strength resin sand, high-strength high-quality cast iron, which can withstand heavy cutting and maintain accuracy for a long time, with high stability. ● thermally symmetric headstock, high-precision angular contact bearing is installed at the head and tail of the spindle, effectively ensuring rigidity and accuracy. The main shaft with increased diameter and thickness is adopted to further enhance the rigidity. The main shaft is driven by a high-power motor, with high horsepower and high torque. High precision heavy cutting can be realized even at low speed. ● the feed system adopts ball screw with enlarged diameter and pre stretching, which can increase the rigidity of the screw and effectively prevent the thermal deformation of the screw. ● screw type and chain type automatic chip removal structure are combined to ensure smooth chip removal. ● the X / Y axis adopts imported heavy-duty plastic guide rail, and the Z axis adopts rectangular hardened plastic guide rail, with low wear and high load, ensuring the long-term accuracy of the machine tool and greatly improving the accuracy and rigidity during cutting. ● the distance between the spindle center and the z-axis guide rail surface is short, which greatly reduces the turning moment and improves the rigidity. The spindle adopts modular design, and a variety of functional modules are available for customers to choose, suitable for various types of processing. ● the X / Y / Z axis adopts C3 imported ball screw, with fixed support at both ends. It is driven by non gear gap torque increasing synchronous belt, with large output torque, fast moving speed and good processing performance; Pre stretching structure, supported by high-precision large contact angle precision bearing, has extremely high moving accuracy and excellent thermal stability.
