Design And Manufacture Of Lathes - Big Bore Lathe and Oil Pipe Lathe
Heavy Duty Precision Lathe
● The lathe bed is made on high-strenght cast iron FC-25.
● The bed with high tensile structure for heavy catting feature.
● Lower portions of bed casting are box-shaped and with chip pan use.
● 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.
● 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.
● The taper attachment was designed for easy operate and rapid cut taper in high accuracy, the device will produce a ±10 angles.
● Electric cable in steel cover to protect wire from chips and preventing trouble with electric wires.
