| Engine Lathe CY6250B,CY6266B Feature |
| ·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. |
