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.

Features

  • The headstock, gear–box, apron and bed–ways are made of high quality cast iron! and they are all cast with the resin sand foundry technology. The hardness of induction hardened bed–ways is around HRC 55.
  • The lathe is featured of high efficiency! high precision, high rigidity and excellent cutting performance.
  • The base of the bed is cast into mono–block with a chip space. The structure ensures high rigidity of the whole machine and convenient chip disposal.
  • The spindle supported by 3–pointed high–precision bearings and all gears in headstock are precisely grinded the spindle turns smoothly at high speed. The noise is lower than 76db at 2000rpm.
  • Foot brake, overload protection, chip guard! longitudinal automatic stop device, point–to–point control in spindle, manual lubrication pump, ensures easy operation and good performance of the machine.
  • When DRO is equipped (GS Model), the lathe is capable of CSS (Constant Surface Speed) function which ensures optimum cutting conditions and surface finish.
