Single Axis Gun Drilling Machines
Single Axis Gun Drilling Machine

These machines are built to manufacture high precision parts and can be customized to suite high volume requirements. These machines provide excellent straightness, surface finish and bore tolerance. Length to diameter ratios of up to 125 is possible.

Machine Features
  • Component counter Rotation to ensure excellent straightness
  • Use of ball screw and servo drives for linear motion.
  • Multiple tool steadies to provide tube support.
  • Rotating cone / Self centering chuck for part clamping.
  • High pressure coolant filtration system
  • Oil chilling and automatic lubrication.
  • Mitsubishi / Siemens PLC controls with touch screen HMI.
  • Integrated design to reduce overall machine footprint.
  • GVN06C Model has Ultra high speed precision motorized spindle.
  • Tool monitoring system to ensure tool breakage prevention.
