Machine bed adopts the box-shaped structure, one-piece moulding casting technology, and 75-degree slant bed base. Turret uses 12-station imported high rigidity hydraulic turret. The spindle motor adopts two-speed AC servo motor which is stepless speed change, matched with imported 1: 1 and 1: 4 two-speed reducer, which ensures big torque output and is suitable for heavy cutting. X, Z, E axis feed drive using brand-name high-precision ball screw, three-axis guide by the intermediate frequency quenching to ensure that the machine feeds precision and rigidity of the best combination. The sub-spindle is driven by the FANUC feed servo motor, hydraulic power is used to lock and release, and the motor shaft is directly connected with the ball screw. With the hydraulic power to lock and unlock, the motor shaft and ball screw directly connected. Equipped with hydraulic self-centering steady rest which layout with vertical opening up, can achieve the workpiece vertical loading, but also can achieve cutting workpiece from the opening of the steady rest. Sub-spindle installs φ400mm self-centering dead hole chuck, also can be with the axis type centre.
