500mm swing over bed CNC lathe –2000mm machining length1
Main performance（CN-K50B-2000）:
1. One piece casting base and bed, keep high rigidity, good accuracy and stable performance.
2. Swing over bed diameter :500mm
3. machining length 2000mm
4. Distance between guild way on Z-axis of the bed:420mm
5. Distance between guild way on X-axis of the bed:230mm
6. Centre of height: 265mm.
7. Spindle bore 82mm.
8. Spindle without gear box, motor driving directly
9. Beijing 11kw servo motor.
10. Spindle head model: 1:20 / Ø90
11. Independent spindle, it is very better to machine casting work piece and heavy duty.
12. GSK 980 controller
13. Servo motor, thread device, automatic lubrication, full cover protection for ball screw and lead rails.
