UNIVERSAL LATHE CY-6140B CY-6240B, CY-6150B,6250B,6166B,6266B Lathe Features ★ High rigidity spindle system, with absolute temperature rising no higher than 35℃.
★ 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. The bed ways are induction-hardened, with hardness around HRC 55.
★ The spindle supported by 3-pointed high-precision bearings and all gears in headstock are precisely grinded, the spindle turns smoothly at high speed.
★ Rapid feed system to improve efficiency. Wide range of feed and pitch are available without changing gears.
★ When rapid feeding is on, the tool slide longitudinal travel handwheel will be automatically disfunctioned.
★ 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.
★ With capacity of swing over bed 660mm, swing in gap 830mm, distance between centers 1000 – 5000mm, this lathe covers wide range of working pieces.
