①The spindle motor is driven by the elecric 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 predision of the motor.
②Row tool,with fast moving speedmore compact structure,and morestable and reliable mechanical precision
③The guide rail of the machine tool body is designed with high and lowr ails,the machine tool body is cast as a whole,and the internal stress is eliminated through multi-channel aging and heat treatment process,so that the machine tool can maintain the optimum predsion and rigidity for a longtime.
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 system pressure 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.
