Product Description

CNC  Deep hole  barrel  drilling and boring machine tool

Product Description

Machine brief :

  The machine is special equipment for machining deep cylindrical hole of workpieces.It can be perfectly suited for drilling and boring through holes,blind and step holes in workpieces;Such as ,spindle of various kinds of machines,many kinds of hydraulic oil cylinders and cylinders and drill collars in the gas and oil field.

   It adopts BTA processing method,it can not only drill the deep holes,but also bore the deep holes. When drilling the workpiece,it adopts BTA chip remove method,that is: the coolant liquid arrive the drilling parts through oil supply device,the iron chips and coolant oil return to the drain back tank and chips removal device through the drilling bar hole.through the above method to realize the drilling purpose.

  When boring the workpiece,we adopts pull boring front chip removal method(pull the boring head go ahead,and remove the front chips by that way) , the headstock spindle front equips chips removal device,used for boring and chips remove. When boring the workpiece,the workpiece rotary,so as to enhance the boring accuracy. The workpiece adopts double taper plate fasten Position,workpiece fasten easily. Position liable
