gun drilling machine

gundrilling machine,good quality

This machine is specialized in deep hole drilling purpose with properties of high efficiency, high accuracy and high automation.   It adopts external-chip removing method (gun drill method).Through one continues drilling, it can instead of traditional drilling, expanding and reaming procedure and arrive the machine accuracy and surface roughness requirement in one time

The machine is controlled by CNC system with function of both single action and automatic recycling. So that it can not only meet the requirements of small batch, but also can meet large batch.

The machine can drill through hole, blind hole and step hole.   The machine can be widely used in the line of automobile and motorcycle, mould, military and aeronautics.
