Gun Drilling Machines

Highest level of performance

Nagel in collaboration with our wholly owned subsidiary TBT of Germany designs and builds high-quality deep hole drilling machines primarily for smaller diameters.

Most Prepared for The Future

Every machine is custom designed specifically for the application by utilizing proven subsystems. New and re-sharpening of gun drills are supported locally by TBT.

Low volume flexible machines are designed for quick change-over and can be partially or fully automated. High Volume Production systems are fully automated and require very little operator intervention.

Equipment is built to customer specifications.

Some of the features of the equipment include:

  • Counter rotation of part for a straighter bore
  • Broken tool detection system
  • Coolant pressure monitoring
  • Siemens / AB PLC controls with ability to store up to 100 part programs
  • Fully independent spindles for multiple spindle machines with multiple HMI’s with the ability to simultaneously run different part types
  • Laser aligned for additional accuracy
