When performance, reliability, and safety are on the line, every component of a firearm must meet exacting standards. At Hinz Company, we understand the high stakes of firearm manufacturing. With decades of precision machining expertise and a state-of-the-art lineup of Swiss-type CNC turning centers, we deliver custom firearm components with unmatched accuracy, repeatability, and efficiency.

From small-caliber civilian rifles to mission-critical components for defense applications, Hinz Company’s firearm Swiss machining capabilities are trusted by manufacturers who refuse to compromise.

What Is Swiss Machining — and Why It Matters in Firearms

Swiss machining is a specialized form of CNC turning that originated in the watchmaking industry of Switzerland. Unlike traditional lathes where the workpiece is stationary, Swiss-type lathes support the material very close to the cutting tool, minimizing vibration and enabling precision down to the micron level.

This makes Swiss machining ideal for producing complex, tight-tolerance parts with small diameters, often required in firearm mechanisms. Components such as firing pins, extractor components, plungers, pins, detents, triggers, and gas system parts are all ideally suited for Swiss turning processes.

Our Swiss Machining Capabilities

At Hinz Company, our advanced Swiss machining centers can produce intricate firearm components in high volumes with consistent precision. We specialize in:

• Tight tolerance parts (±0.0002” or better)
• Multi-axis machining with live tooling for complex geometries
• Bar-fed automation for high-efficiency production
• Lights-out manufacturing to meet large-scale orders with quick turnaround
• Tool life monitoring and in-process quality control for consistency

Whether you need prototypes for a new weapons platform or production runs of hundreds of thousands of parts, Hinz Company has the capacity and expertise to deliver.

Materials We Work With

Firearm components must withstand extreme conditions, including high temperatures, pressure, and mechanical stress. Our Swiss machining department is well-equipped to handle a wide range of high-performance materials:

• Stainless steels (416R, 17-4PH, 303, 304, 316)
• Tool steels
• Titanium
• Aluminum alloys
• Brass and bronze
• High-temp alloys

We know how different materials respond to machining stresses, and we adjust our tooling and cutting parameters to maintain integrity, finish, and dimensional stability.

Key Firearm Components We Manufacture

Our firearm Swiss machining services are used by manufacturers of:

• AR-style rifles and pistols
• Bolt-action hunting rifles
• Military and tactical platforms
• Handguns and revolvers
• Precision competition firearms

Some of the common parts we manufacture include:

• Firing pins – critical components where strength and accuracy are paramount
• Safety selectors and detents – requiring smooth surface finishes and exact fit
• Trigger components – precision-fitted for clean, reliable operation
• Pins, screws, and bushings – small, essential parts with tight tolerances
• Gas system components – machined for exact timing and function

We also offer custom firearm parts based on customer specifications, working closely with clients through every stage — from concept to full production.

Quality You Can Count On

At Hinz Company, quality assurance is embedded in every process. Our inspection and testing protocols include:

• First article inspection
• In-process monitoring
• CMM and optical comparator validation
• Material traceability and documentation

We are committed to delivering parts that meet or exceed industry standards, including ITAR compliance and military specifications when required.
