Main features:
1. A dynamic sliding bearing is adopted at the spindle nose. These bearings offer superior precision and have obtained a national patent.
2. The spindle has 18 speed changes, with a speed range of 30–1000 r/min and a large spindle bore (Φ120 mm).
3. High – power, low – noise servo motors and precision ball screws are employed on the X and Z axes, granting the machine high positioning accuracy, good stability, and high reliability.
4. The machine is outfitted with a four – position automatic rotary turret featuring intermittent automatic lubrication, which users can adjust as needed. It fully ensures the lubrication of the rail surface and effectively enhances the machine’s accuracy.
5. The machine boasts a double – door and semi – protective structure, resulting in an attractive appearance and ease of operation.
