Micro Gun Drilling Machines
Micro Gun Drilling Machine

These machines are designed for small hole diameter drilling usually required in medical implants. They also find application in aerospace and automotive industries. Precihole’s own component manufacturing experience over 30 years helps ensure that all the necessary complexities in small hole drilling of such applications are incorporated in the design of key features on this  machine. Machine can be customized to accommodate production volume requirements and provide excellent straightness, surface finish and bore tolerance.

Machine Features
  • ‍Ultra high speed precision motorized spindle
  • ‍Component Counter rotation to ensure excellent straightness
  • ‍Use of ball screw and servo drives for linear motion
  • ‍Multiple tool steadies to provide appropriate tube support
  • ‍Three jaw self-centering chuck clamping arrangement arrangement
  • ‍High pressure coolant and fine filtration system
  • ‍Oil chilling and Automatic Lubrication
  • ‍Mitsubishi / Siemens PLC controls with touch screen HMI
  • ‍Tool monitoring system to ensure tool breakage prevention
