①The spindle motor is diven by the electric spindle with superior output torque,symmetric with 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 ofthemotor.
②Integrated servo hydraulic tool rest,with more compact structure,and more stabe and reiable 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 intemal stressis eliminated through multi-channel aging and heat treatment process,so that the machine tool can maintain the optimum precision and rigidty 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 avis of the machine tool adopts theinclined 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.
