①The spindle motor is driven by the electric spindle with superior output torque,and the integrated cooling fan is adopted,so as to ensure the operating temperature of the motor and guarantee the service life and machining precision of the motor.
②Integrated servo hydraulic tool rest,with more compact structure,and more stable and reliable mechanical precision
③The guide rail of the machine tool body is designed with high and low rails,the machine tool body iscastasa whole,and the internal stressis eliminated through multi-channel aging and heat treatment process,so that the machine tool can maintain the optimum precision and rigidity for a long time.
④For the hydraulic test and adjustment,the panel is installed in front,with mechanical rotation operation,and it is easy to monitor and adjust the hydraulic systempressure from the front of the machine.
⑤The X axis of the machine tool adopts the inclined design of 30°,RG35 roller linear guide rail and RG32 roller screw,with the advantages of strong ability to offset heavy cutting vibration and high precision.
⑥Sub-spindle:the spindle adopts the built-in synchronous electric spindie structure with high power,torque,speed and precision,suitable for machining various parts,with low speed characteristics,suitable for C-axis cutting.The sub-spindle can be moved at high speed and butt with the main spindle to realize the machining of the positve and negative sides of the parts under one-time camping
