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 upper part of the lead screw and polished rod of the machine tool is designed with a stainless – steel protective cover (a national patent). The protective cover can prevent iron chips from entering and also protect the safety of operators, fully complying with national safety standards.
3. The spindle has 12 manual speed grades, with a speed range of 37–1600 r/min and a large spindle bore (Φ102 mm).
4. The lathes are supplied with two systems, both metric and inch.
5. Electrical systems with different frequencies and voltages can be designed to meet the requirements of users.
