Machine tool for the machine, electricity, liquid integrated layout, 45 ° overall inclined bed, with a compact structure, high rigidity, smooth chip, easy to operate, etc.; rail type for the rolling guide, drive parts using high-speed silent ball screw, With fast speed, less heat, high positioning accuracy of the advantages of machine tools for the whole closed protection, automatic chip removal, automatic lubrication, automatic cooling.
the whole resin sand and gray cast iron bed, the casting structure by the finite element analysis and optimization, casting by the second aging treatment, with high rigidity and high stability; finishing high precision gantry machining center processing, high geometric accuracy ; Inclined bed layout, with high rigidity, compact structure, smooth chip, easy to operate the advantages of bed guide rail for the rolling guide, the friction coefficient is small, moving fast, high positioning accuracy.
Spindle and Headstock
The robust headstock casting is mounted on the same ground surface as the tailstock to maintain perfect alignment and center height. The heavy- duty spindle is supported by 3 sets angular contact bearings in the front and 2 sets at back, and duplex angular thrust bearings in between. Cylindrical roller bearings feature a large contact surface which ensures the highest rigidity for heavy loads and high surface finishes. All spindle bearings are precision NSK class P4 and are permanently grease lubricated.

The lathe features a 25 HP spindle motor with a gear transmission in (1:5) gear ratio. The speed is up to 1,000rpm. It has a 106 mm (4.2”) of spindle bore and bar through draw tube is 94 mm (3.7”) in diameter. The maximum spindle torque is 880 NM (650) ft.-lbs of torque at 200 rpm spindle speed.
Ball screws
βiSc series AC servo motor, high-speed silent ball screw, flexible coupling directly connected, moving fast, positioning accuracy and repeat positioning accuracy; built-in absolute encoder, no cumulative error, no memory, no need to find a reference point , The location information is not lost after power is removed. Double nut and C3 level high accuracy ball screws.
Screw diameter x pitch: 32x8/40x10
C3 level 0.008mm/300mm
The ball screw adopts the pre-load process, which effectively reduces the back lash in the ball screw and helps reduce the heat transfer and friction. This improves the accuracy and strengthens the rigidity and heat deformation resistance
Hydraulic tailstock
The machine features a hydraulic tailstock that can be activated by the program, or controlled via the standard foot switch. The tailstock features an MT5 taper, and provides up to 6.5kN of thrust.
