Description

CK7520 series CNC lathes——its strength, dynamic and static rigidity, mechanical structure of main parts, guard and coolant system are all advanced in design. This series lathe, designed with high vibration strength, adopts high grade cast iron, integrated bed and base, slant guide ways, a high precision through-hole spindle driven by large-field AC main motor. Key parts like bearings of main spindle and that of feeding screw are all famous foreign products. The multi-station turret rotates fast and continuously with a high repeatability and changes tool in nearest path. The lathe can be equipped with FANUC 0i-TD, FANUC 0i Mate-TD, Siemens 810D, 802D, DASEN 3i etc on request, or other top brand controls from both China and foreign countries. The hydraulic parts, lubrication units and chucks are all good-quality from both domestic and foreign markets. The lathe is designed with unique appearance, easy-operated panel, full-enclosed guard, which can prevent the leakage of water, power and oil effectively. It is the most powerful product in its class due to the large power, excellent accuracy and high performance. Features (1) Integrated base and bed made of high grade cast iron is of high rigidity with wide rectangular hardened ways. (2) High grade cast iron saddle and slide, plastic-coated ways, small dynamic and static friction force. Rapid traverse rate of X and Z axis is up to 12m/min and 16m/min. Wide span saddle and slide ensure large-loaded and heavy cut.
