those  machines 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.   

     the machine is controlled by CNC system with function of both single action and automatic machining, inorder to provide processing 

Efficiency,the machine is  equipoed with 2or4 power head,so that it can meets the requirements of 

Small Batch and large batch machining.

    the machine 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 automobile andmotorcycle,moule,military and aeronautics.
