CK7520 CNC Turning Machine

Product Description

CK7520 CNC Turning Machine
Main feature:
CK7520 series CNC lathes, its strength, dynamic and static rigidity, mechanics 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, one piece of bed base, slant guideways, a high precision through-hole spindle driven by large-field AC main motor. Key parts like bearings of main spindle and of feeding screw are all famous foreign products. The multi-station turret indexes fast and continuously with a high repeatability and changes tool proximately. The lathe can be equipped with FANUC 0I-TD, FANUC 0I Mate-TD, Siemens 810D, 802D, DASEN 3I and etc on request. Or other top brand control systems from both China and foreign countries (hydraulic parts, lubrication units and chucks that are 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.
