HEADSTOCK
The main spindle is forging as whole-body and sustained by precision bearings.
   The speeds of spindle have 12 steps and designed on theoretical base.
All gears and shafts are made of Ni-Cr-Mo steel and carbonize and ground.
Control of main drive through electromagnetic brake, and automatic forced lubrication.
GEAR BOX
The Gear box is entirely enclosed contruction and provide a large of feedings or thread cuttings (inch, metric, module pitch and diametral pitch). Inch and Metric threading with out changing gear.
Oil both lubrication and built in safety clutch safeguard the continuous and proper operation of the universal gear box.
CARRIAGE & APRON
The compound rest can be fixed the cross-silde anywhere, convenient cutting work application.
The apron have automatic lubrication and locked-safe device protect threads and feeding same as operation. Rapid traverse drive for longitudinal-cross feeding and forward & reverse feed are operating very light and convenience.
TAPER ATTACHMENT
