The machine is noted for its high rigidity and precision.
Spindle systems of headstock, tailstock and wheelstock have the good structural property, large carrying capacity and the strong rigidity.
The rate of stepless speed regulation can be changed within 320r/min. It makes you very pleased to select the best surface rounghness and the highest cutting efficiency.
The transverse feed of wheel has two sets of devices, that is automatic periodic and manual micro-feed. It guarantees to obtain accurate and dependable feed.
The machine is equipped with many kinds of attachments, such as wheels, dogs, coolant tank, and wearing parts, and complete set of usable tools.
