Features:

This series extra heavy duty horizontal lathe is the most advanced lathe adopted with the famous Germany technology. Adopting the most advance technology in both domestic and worldwide, the lathe owns the features of high precision, high rigid, high stability, and long term precision keeping, on the top level of the same type machines. The main transmission system and feeding system adopts separate type structure. It can finish the high precision and high efficiency turning work for the workpiece like cylindrical, inner hole, end surface, cone surface, screw(outer & inner), round arc, groove, etc.

1. The overall thick-walled closed headstock, large diameter, short spindle, high precision spindle rotation system, and the use of independent thermostat oil cooling.

2. The bed is one piece type bed with three or four guideways. There are telescope type protection covers.

3. High precision spindle rolling bearings effectively guarantee the accuracy of rotation.

4. Tailstock sleeve and spindle are large diameter and high-precision structures, and center is large diameter and short taper forming, heavy carrying capacity and high precision turning.

5. Main parts structure was designed by finite element analysis, with good static and dynamic characteristics, to optimize state. The main castings are resin sand molding, high-frequency electric furnace smelting iron with high strength and low stress, and pass annealing, vibrating, and times aging stress relief methods, allowing the machine to get a very good stiffness, maximize the elimination of the material and structural stress, long-term stability of the machine precision can be guaranteed.

6. Headstock and feed box are processed on imported CNC boring and milling machines and machining centers, its roundness, concentricity, parallelism of axes have been strictly controlled.

7. Bed guideways, shafts, gears and other parts are all after heat treatment, and precision ground, which improves the transmission accuracy of the machine.

8. The machine can come with DRO system as requirement, which can display the longitudinal and cross moving distance.

9. The machine can be equipped with close open type steady rest according to user needs.
