Flat Bed CNC Lathe SK61126Z Series |
|
|
|
FEATURES: |
◆ The SK61206Z series CNC lathe adopts German advanced manufacturing technology of CNC machines, is meticulously manufactured with high reliable parts. Apsrt from the featuresof high accuracy, large power and high rigidity, the lathe is also endowed with various functions as well. The main components and structure have been undergone a very optimized design, which makes the machine be the first choice for machining work piece like shafts, discs, special shape surfaces, worms and so on. |
|
◆ The steps less speed change of main spindle is accomplished by DC speed control system which produced by Siemens. Both Z and X axis are in semi-closed loop control, Spanish Korta ball screw makes the machine obtain excellent positioning accuracy. | |
