Vertical Honing Machines
Precihole Vertical Honing Machine

Precihole Honing Machines incorporate the latest features to finish and polish bores for small and medium caliber weapon systems. The choice of appropriate honing tooling and technology is made after careful evaluation of the production requirements of the barrel length and caliber. This maximizes production and reduces operator intervention. Surface finish up to 0.1 Ra is possible. Precihole honing machines can polish bore sizes from 7.62 caliber to 40 mm caliber up to lengths of 2500 mm. Precihole provides a complete solution that includes the machine along with tooling and tooling accessories.

Machine Features
  • Use of hydraulic cylinder for linear reciprocation and servo  technology for mandrel expansion
  • Special fixturing for quick component location and clamping
  • 5 micron fine coolant filtration system
  • Mitsubishi / Siemens PLC controls with touch screen HMI
  • User friendly screens and simplified machine operation
  • Air gauging to measure the bore size accurately
