Pull Reaming Machines
Pull Reaming Machine Hero

Precihole Pull Reaming machines provide all necessary features to improve the surface finish and size consistency in the bore of a gun barrel. This operation is next after gun drilling. Pull reaming removes all irregularities in the hole by improving surface finish and preparing the hole for rifling. The machine can be configured to be robot ready. This includes automation for reamer insertion and retrieval as well as auto door opening and closing.

Machine Features
  • Robot readiness for easy integration in an automated cell
  • Automation for reamer insertion and retrieval
  • Integrated unibody design for a compact footprint
  • component indexing arrangement for ease of loading and unloading parts
  • High pressure coolant and fine filtration system
  • Oil chilling and Auto Lubrication
  • Mitsubishi PLC controls with well-designed operator friendly screens
