Friction coupling is used in the headstock transmission chain for its easy adjustment.
Single layer table, with an oblique angle of 10 degree, longitudinal traverse can be operated either by hand or by power.
Wheel head rapid approach and withdrawal effeced by hydraulic means can be digitally displayed at a resolution of 0.005mm.
The wheel spindle being of 80mm in diameter has good rigidity and strength
The roller ways are for wheel head movement
The bed ways and wheel head ways are lubricated in an automatic cycle by means of the oil pump.
Plastic coat is adhered to the bed way.
