1, The CK450 CNC lathe adopts the overall casting 45 degree inclined bed and disc plate structure. The headstock and other main parts are made of high strength cast iron with reasonable distribution of thick tendons.

2 the whole machine and main parts are designed and analyzed by advanced software to optimize the structure and parameters.

3 The main main parts are processed by the imported five face machining center, with high precision and small error, and the aging treatment of stress is eliminated two times. It has high strength,stiffness,precision retention,impact resistance and seismic resistance.

4, The guideway of the saddle is combined with hardening and sticking. Good dynamic performance,combined with ball screw C3 (JIS), can greatly improve the machining accuracy and production efficiency of the equipment.

5. Spindle motor and two axis servo motor are driven by high power and superior servo motor. The driving motor with strong torque is directly connected with the ball screw without any gap. The rotation is stable and reliable, and the positioning accuracyis improved.

6 the spindle unit adopts the first three columns and the latter two columns of high-precision bearing support. Ensure maximum axial, radial rigidity and optimum surface machining quality of spindle. The spindle motor uses AC servo spindle motor to realize CVT in full speed range, and equipped with mechanical hydraulic automatic locking fixture.

7. The hydraulic turret is fast, accurate and stable. Can achieve two-way rotation, near the knife. Hydraulic clamping, large clamping force, suitable for powerful cutting;
