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. |
·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. |
