[Description]
1.The machine is used for machining alloy mandrel with tapers on both ends for seamless steel pipe. It can carry out cylindrical, surfacing, grooving, tapering drilling on faces,external grinding on the machine etc.The materials of workpiece is mainly X40GMV5,Its hardness is 315-360,roughness of workpiece is Ra1.6,it will be Ra 0.4-0.8 after being burnished.
2. Main drive is of two steps with mechanics, and speed adjusting is done by AC frequency changing motor.
3. Feed movement (X,Z) is driven by AC servo motor.
4. The spindle box is fixed on the bed, the carriage is of swivel long tool carrier.
5. Tailstock is adopting upper and lower parts, spindle in quill is on precision rolling bearing. pisk spring protects the quill from overload because of workpiece expanding, having features of rapid speeds .
