Product Description

Performence Features:

Four different work speeds are obtainable by making use of a double-speed motor and the belts in the headstock.
Union chucks are used in the headstock and tailstock for an adjustable eccentricity up to 120mm.
Friction coupling is used in the headstock transmission chain for its easy adjustment.
Table traverse is operated either by hand or by power.
Rolling guideways are used on wheelhead. And made by high quality material, the wheel spindle being of 80mm
in diameter has good rigidity and strength.
The wheel spindle being of 80mm in diameter has good rigidity and strength.
Plastic coated bed ways with less friction.
The bed ways and wheelhead ways are lubricated in automatic cycle by means of oil pump.
Additional synchronizer for headstock and tailstock, i.e. the gears of headstock drive the tailstock to run in
synchronism through the connecting spindle, thus. Four different speeds are obtainable. The length of
works is ranged from 800mm to 2000mm.
The digital display device can be optional
