those  machins is a special-purpose deephole drilling machine with properties of high efficiency,high accuracy 

and  high automation.It adopts external-chip removing method (gundrill method),Other equipment requires drilling,

Expanding, reaming processes to achieve the machining accuracy and surface roughness, the machine  through once 

Continues drilling can be achived.   

    those machines is controlled by CNC system with function of both single action and automatic machining,so that it can

Meets the requirements of Small Batch and large batch machining. three servo axis(x,y,z),using servo motro drive ball

Screw pair,the feed of the three servo axis and cutter rotation are stepless.

    They can drill through hole,blind hole and step hole.Eccentric hole and inclined oil hole can also be processed

When special tooling is used.                             

    those machines can be widely used in the line of automobile and motorcycle,mould,military and aeronautics.
