Vertical Honing Machines
Precihole Vertical Honing Machine

High precision barrel manufacturing requires the bore to be honed to precision before rifling. The surface pattern, surface finish, and taper ovality achieved on these machines is excellent. Precihole vertical honing machines incorporate all the features necessary to upgrade the quality of gun barrels to make them high precision. Honing solutions offered by Precihole are complete solutions comprising of the machine, tooling, and tooling accessories, as well as recommendations on honing oil suited for this fine machining operation.

Machine Features
  • Use of servo technology for precision control over linear motion, spindle rotation and tool expansion
  • Modular design to support single or multiple spindles
  • Operator friendly self-learning controls with custom screens
  • Fine coolant filtration system with oil chilling and rare earth magnetic separator for optimal process performance
  • Option of linear indexing table and part loading fixtures for multistage high production honing requirements
