Deep Drilling Machine

deep drilling machine 1. Adopt gun drilling method 2.Especially for big diameter holes and special workpieces

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.    Main Technical Parameters:
