Product Description DESCRIPTION: CK7156/20/30 CNC lathes are the latest products manufactured with advanced thchnologies licensed by Daewoo Heavy Industries Ltd. (South Korea). Its strength, dynamic and static rigidity, mechanics of main parts, safety device and cooling system are all designed according to Turning Center. The strengthed casting base and exclusive slant bed provide excellent rigidity and dampening, coupled with con-venient chip removal. A high precision through-hole spindle driven by powerful AC main motor feature the stability and low noise during operation. Key parts like bearing on the ball screw and main spindle are all famous foreign products, ensuring the higher machining accuracy and longer part life. The multi-station turret indexed fast and nonstop bi-directionally with a high repeatability. The CNC system is optional with FANUC0-TC, 0-TDII or others as required. The hydraulic parts, lubrication unit and chuck are all famous domestic or foreign products as well. The new designed CK7516/20/25/30 feature easy panel operation and complete protection. They are undoubtedly the most powerful products in their class due to their excellent accuracy and stability.
