①The spindle motor is driven by the electric spindle with superior output torque,symmetric wth the submerged spindle box for water cooling and heat dissipation to ensure the operating temperature ofthe motor and guarantee the service life and machining precision of the motor.
②Integrated servo hydraulic too rest,with more compact structure,and more stabe and reiable mechanical precision
③The guide rail ofthe machine tool body isdesigned with high and low rails,the machine tool body iscast as a whole,and theinternal stresss eliminated through muti-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 panelis installed in front,with mechanical rotation operation,and it is easy to monitor and adjust the hydraulic system pressure from the front of the machine.
⑤The X axis of the machine tool adopts the inclined design of 30°,RG45 roller linear guide rail and RG40 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 spindle structure with high power torque,speed and precision,suitable for machining various parts,with low speed characteristics,sutable for C-axis cutting.The sub-spindle can be moved at high speed and butt with the main spindle to realize the macining of the positive and negative sides of the parts under one-time clamping.
