FEATURES:
Axial shaving and plunge-in shaving operations are avaiable.
Crowned gear and tapered gear can be shaved on the machine.

The machine is 2-axis controlled(radial and axial motions)and driven by a servo motor system.

High precision and high-rigidity bearings are adopter for the spindle and the tailstock.
The worktable and crowning mechanism are of high rigidity.
High-rigidity and high-precision ball screws are used for the radial,axial and tangential motions.
Rversible magnetic chip conveyor.
