Precihole manufactures a compact and precise straightening press for gun barrels. Barrel blank straightness is a very important factor that determines the accuracy of the weapon system. Barrel is a long slender shaft that is likely to bend during many stages of heat treatment and machining as it goes through all the way from bar stock to a gun ready profiled and chambered barrel. It is very simple to use and does not require any special operator skills.

Salient Features
  • Compact and robust design to accommodate all varieties of barrel steels and shaft Ods
  • Use of linear motion rails for adjusting lengths and movement of precision dials
  • Precise control over straightness achieved over the entire length of the barrel
  • Simple operator friendly controls
