~Introduction

CH75 series CNC turning center, based on foreign advanced technology which is introduced and absorbed by us, has drilling, milling and tapping functions. Its strength, dynamic and static rigidity, mechanics of main parts, guard, coolant system and safety are all advanced in design. The integrated base and slant bed guideways provide the machine an excellent rigidity and flute chip removal. A high precision through-hole spindle driven by powerful AC main motor and dampening design enhance the running stability. Key parts like bearings of main spindle and of feeding screw are the products of SKF made in Sweden and NSK made in Japan, which make low noise during operation, ensuring the higher machining accuracy and longer service life. The 12-station power turret indexes fast continuously in bi-direction with a high repeatability.

The machine standard configuration is FANUC 0i-TD system. The hydraulic parts, lubrication units and chucks of the machine are all good-quality foreign or domestic products.

The machine is designed in unique appearance, with easy-operated panel and full-enclosed guard, which prevents 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.
