Product Description

CY series GAP-BED LATHE CY6250B have all the structural and performance characteristics of conventional lathes. Saddles are attached to the bed, which expands the processing range of conventional lathes. The saddle is easy to disassemble and has high repeated positioning accuracy. After dismantling the saddle, special shape parts and large diameter disc parts can be processed. It is widely applicable to single piece or batch production in mechanical processing industry.

Characteristic

The headstock gear-box, apron and bed-ways are made of high quality casting iron, and are all casting with the resin sand foundry technology and aging process. The bed ways are induction-hardened, with hardness around HRC 52.

The spindle supported by 3-pointed high-precision bearings and all gears in headstock are precisely grinded, 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 hand-wheel 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.
