Main features:
1. A dynamic sliding bearing is adopted at the spindle nose. These bearings have superior precision and have obtained a national patent.
2. The spindle has 18 manual speed grades, with a speed range of 12–1000 r/min and a large spindle bore (Φ120 mm).
3. The lathes are supplied with two systems, both metric and inch.
4. Electrical systems with different frequencies and voltages can be designed to meet the requirements of users.
