Engine Lathe

The headstock, gear-box, apron and bed-ways are made of high quality cast iron, and are all cast with the resin sand foundry technology and aging process. The bed ways are induction-hardened, with hardness around HRC52.
The spindle supported by 3-pointed high-precision bearings and all gears in headstock are precisely ground, the spindle turns smoothly at high speed.
High rigidity spindle system, with absolute temperature rising no higher than 35°C.
Rapid feed system to improve efficiency. Wide range of feed and pitch are available without changing gears, distance between centers 1000-5000mm, this lathe covers wide range of working pieces.
When rapid feeding is on, the tool slide longitudinal travel handwheel will be automatically nonfunctional.
Reliable safety devices such as footbrake and emergency power-off switch are assembled. Adjustable overload protection device is also installed in the feed system.
The tool post adopts the structure of ratchet pawl, and can be relocked by turning the lever for just half a lap.
Tailstock are equipped with double-locked mechanism, smooth and effortless movement is ensured by the elastic scroll devices underneath.
