Single Axis Gun Drilling

This series is our most popular series and has 100s of applications in dozens of industries. This series covers drilling range from Ø2mm to Ø40 mm and lengths of parts up to 1500 mm. Machines are designed for 3 shift production mode and provide all the features for excellent output parameters like straightness, bore tolerance and surface finish.

Pull Reaming

Precihole’s pull reaming machine series combines high speed sizing of holes. Surface finish as well as consistency of holes across the length of the part is vastly improved after pull reaming.Primary application of this series is in firearm manufacturing for all small caliber weapon systems.

Facing & Centering

Facing, Chamfering and centering machines are specifically designed to accommodate high volume needs to face, center and chamfer cylindrical shafts at both ends in one setup. The tool plunges into the work piece ends and does all 3 operations in one shot. Cycle times are typically less than 30s. This machine is ideally suited for use in firearm and automotive industries.

Vertical Honing

Precihole’s Vertical Honing Series is versatile and incorporates all the necessary features to produce excellent sizing and surface finish in a variety of parts in various industries. Precihole also provides all the fixturing and tooling needed for sizes ranging from Ø5 mm to Ø40 mm in this series.

Button Rifling

Button Rifling Machines incorporates the latest features to form precision grooves in small caliber weapon systems. The rifling button is pulled and rotated precisely through the barrel. Precision in rifling is critical. The machine uses anti­ backlash helical guides and rotary encoder to interpolate linear and rotary motion. This produces rifling twists exactly as needed by the rifling tool. Machine features include load monitoring that graphs the rifling pull load on the HMI. Operator can monitor the rifling operation on screen, output to printer orflash disk if required.
