  • These Heavy Duty Lathes are for turning of cast iron and steel workpieces, turning of non–ferrous metal parts of big or medium sizes. It can do external cylindrical surface turning, inner hole and end face turning. It can also turn various internal and external metric, inch, module and diametrical pitch threads, the top slide can be used independently for turning of short taper.
  • These lathes are of high power, high rigidity and wide rotating speed range, so it can be used for high speed and strong force turning.


  • The side wall of bed is constructed of double-rib plates and internal rib plate employs combined structure of box- type and bevel ribs. Rigidity of machines increases a factor of by 1/3 times compared with that of n-type ribs of single wall.
  • On the apron, there is a device which can move rapidly and safely, and is operated by a single handle which can prevent damage from overload. Braking and rotating direction change of spindle is visualized controlled by hydraulic system.
  • Both rigidity of construction and rigidity of transmission are high, so precision is stable and heavy cut can be carried out.
  • Owing to the saddle guideway which is inlaid with TSF wear-resisting material plate, the carriage moves lightly and nimbly. The service life of the guideway is extended. Lubricating system circulates from the external independent storage tank, thus cutting precision is increased.
  • The tailstock is equipped with a graduated disc and graduated line. The machine is characterized with elegant appearance and easy to be cleaned and maintained.
