Characteristic

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 induction hardened bedways is around HRC52. 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. 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.
