| ZCK50 efficient CNC (bearing) lathe is designed specially for automation machining of external/internal bearing rings from blank process to process before grinding. The machine has the following features: |
 60° slant bed, very rigid. |
| Side mounting chip conveyor conveys chips fluently. |
| High torque and double spindle structure ensures high productivity at large feed. Precision cartridge type main spindle rotates without vibration. |
| Rectangular guide ways are used for X-axis, Z1/Z2 axes. 3-5 station comb type tool rest offers fast tool change. |
| Frequency inverting spindle and centralized operator's panel; |
| Auto parts loading and catching makes it possible for one person to operate several machines. Production cost is reduced. |
