This machine
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),through one
continues drilling,it can realize the machining accuracy and
surface roughness usually by the progress of drilling,expanding and
reaming.The machine is controlled by CNC system with function of
both single action and automatic recycling 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.The machine can be
widely used in the line of automobile and motorcycle,mould,military
and aeronautics.
