①The spindle motor is diven 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 predsion of the motor.
②Integrated servo hydraulic tool rest,with more compact strucure,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 is cast as a whole,and the nternal stress is eliminated through multi-chamnel aging and heat treatment process,so that the machine tool can maintain the optimum predisonand 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 system pressure from the front of the machine.
⑤The X axis of the machine tool adopts the indined design of 30°,RG35 roller linear guide rail and RG32 roller srew,with the advantages of strong ability to offset heavy autting vibration and high precision.
