Product Description
FEATURES:
The machine is suitable to drilling\boring\turning workpiece, it can turning outside of workpiece and thread cutting,and also drilling, boring, trepanning the workpiece.
The deep hole drilling and trepanning
(trepanning less than 300mm) adopt BTA inner chips removal, and boring and trepanning size 300-500 adopt the outside chips removing method.

1.
The machine is composed of machine bed (deep hole part), headstock, drilling box, chuck, steady rest, boring bar support, feeding system, machine bed(for turning), feeding system for turning, turning carriage, coolant system, electric system, and so on.
2.
Machine bed for deep hole process: machine bed width is 1250mm, and double square type guide way,the surface of guide way be quenched, the rack be mount on the back side of machine bed, it can drive the steady rest and support by manual or motorized device.
3.
Mach
i
ne bed for turning, the machine bed width is 900mm, the rack
mounted on the middle part of machine bed for the lon

itudinal of the
carriage feeding
.
Toolpost for turning:
The turning toolpost can move on the whole length of the machine bed guide way, the toolpost can turning the outside and end surface of workpiece, the X direction feeding is realized by the servo motor and ball screw.
