Application

The machine which is a universal style and multi-purpose use engine lathe, can perform various kinds of working such as internal and external cylindrical surface, tapered surface, facing and grooving, threads of metric, withworth, module and diametral pitch system, as well as drilling, reaming, and thread tapping processing and etc. In the gap-bed lathe can machine large diameter disk of irregular shape workpieces. The machine has the performance reliable quality and easy to operate, and it is an ideal equipment for cutting processing.

Featured

  • The headstock, gear–box, apron 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. High rigidity spindle system, with absolute temperature rising no higher than 35oC.
  • 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, 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.
