CK61125E(10) series heavy CNC lathe main structural features
1. Bed: Integral box-shaped structure, using high-standard cast iron (HT300) by one-time molding casting, and after second aging treatment, the guideway width is 970mm.
2. Headstock: The structure of the box body is strong, the gears are quenched and precision ground, with high precision, stable operation, and low noise. The diameter of the spindle is large, supported by precision heavy-load bearings for three-point support, and the rotation is stable, it can perform heavy cutting and finish cutting. Automatic forced circulation lubrication makes the transmission system operate flexibly and can effectively cool down. it can also realize step-less speed change and constant linear speed cutting.
3. Feeding: axis-Z sliding guideway are covered with TSF soft belt, which greatly reduces the friction coefficient and improves the servo response performance, axis-X feeding is driven by AC servo motor which is directly connected with the ball screw through the flexible servo coupling, guaranteed high machining accuracy, positioning accuracy, and accuracy retention. Each motion parts are automatically lubricated by a centralized intermittent lubrication system. 1000-6000MM specifications are driven by an AC servo motor via a high-precision planetary reducer Feeding, the specifications above 8000MM are fed by the rack and pinion drive. The machine tool has high positioning accuracy and repeated positioning accuracy.
