Precihole BSP Series – Shaft & Barrel Straightening Machines

Barrels need to be straightened during various stages of conversion between rod to a finished barrel. Precihole‘s BSP Series provides a compact and precise solution for this operation. Barrel blank straightness is a critical factor that determines the final accuracy of the weapon system. Barrels are long and slender shafts that bend during heat treatment, machining, or stress relieving. This press helps to correct the deflection by holding the barrel in a simply supported configuration and pressing the area with the bend in the opposite direction.

Precihole’s barrel straightening machines are very simple to use and do not require any special operator skills.

Machine 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
