①The spindle motor sdrven by the electrik spindle with superior output torque,and the integrated cooling fan is adopted,so as to ensure the operating temperature ofthe motor and guarantee the service life and machining predslon of themotor.
②Straight Y-axis dynamic milling cutter turet drilling,miling,tapping and other composite machining can be performed for the Y aksi on the end face or the side surface,which can realize the machining concept of one-time damping and all completions.
③The guide rail of the machine tool body is deskgned with high and low rails,the machine tool body is cast as a whole,and the intemal stress is eliminated through mult-chanmel aging and heat treatment process,so that the machine tool can maintain the optimum predsion and rigidity for a long time.
④For the hydraulc test and adjustment,the panel is installed in front,with mechanical rotation operation,and it is easy tomonitor and adjust the hydraulic system pressure from the front of the machine.
⑤The X axis of the machine tool adopts the indined deslgn of 30°,RG35 roller linear guide rail and RG32 roller screw,with the advantages of strong abilty to offset heavy cutting vibration and high precslon.
