What Sets Swiss Screw Machining Apart?
Swiss screw machining delivers unmatched precision, efficiency, and control compared to traditional CNC lathes or automatic screw machines. The process minimizes deflection by supporting the workpiece close to the cutting tool, enabling ultra-precise operations even on very small parts.
Abbott-Interfast uses advanced CNC Swiss machining systems that combine high spindle speeds with multi-tool capabilities. This allows us to complete intricate geometries in a single setup, reduce cycle times, and achieve tight tolerances.
Key advantages of our Swiss screw machining capabilities include:
- Precision tolerances down to ±0.0002 inches
- High-speed turning with multiple tools operating simultaneously
- Ideal for micro-sized components and intricate part designs
- Reduced need for secondary operations
- Enhanced material flexibility and fast changeovers
Swiss Screw Turning for Critical Applications
Swiss screw turning plays a vital role in the production of cylindrical components used in high-performance assemblies. Abbott-Interfast machines a wide variety of threaded and unthreaded parts, including screws, shafts, bushings, pins, and spacers. These components are essential to applications that demand durability, accuracy, and compliance with strict industry standards.
CNC Swiss Machining for High-Volume OEM Production
With fully integrated CNC Swiss machining capabilities, Abbott-Interfast is equipped to handle production volumes ranging from short runs to millions of parts annually. Our facility in Wheeling, Illinois, houses state-of-the-art equipment and bar-fed Swiss turning centers designed for continuous operation and lights-out manufacturing. This enables us to offer fast turnaround, reliable scheduling, and competitive pricing for custom-machined fasteners.

Materials and Capabilities
Abbott-Interfast works with a wide array of materials to support diverse application requirements. Our Swiss screw machining equipment accommodates various metal and plastic stock shapes, allowing us to manufacture components that meet strength, conductivity, corrosion resistance, or weight reduction goals.
Commonly machined materials include:
- Stainless Steel: Grades such as 303, 304, and 316 are frequently used for their corrosion resistance and strength in aerospace, marine, and medical applications.
- Carbon Steel: Ideal for structural strength and cost-effectiveness, carbon steel is used in automotive and industrial components that may require secondary heat treating or plating.
- Aluminum: Lightweight and corrosion resistant, aluminum is often chosen for electronic housings, connectors, and automotive parts that require thermal conductivity and low mass.
- Brass and Copper: These conductive materials are commonly used for electrical terminals, fittings, and decorative hardware, offering excellent machinability.
- Engineering Plastics: Nylon, Delrin (acetal), PTFE, and other polymers can be precision machined to tight tolerances for insulating or lightweight components in fluid power, medical, and electronic systems.
- Specialty Alloys: We also machine harder-to-process materials such as Inconel, titanium, and Monel for high-temperature, corrosive, or high-strength environments.
Our advanced bar-fed CNC Swiss lathes can process diameters up to 1.25 inches (32 mm) and support continuous, lights-out production for maximum efficiency. Every part is machined to customer specifications and verified using in-process quality control, material traceability, and, when needed, custom packaging or part marking.
Frequently Asked Questions About Swiss Screw Machining
Swiss screw machining is a highly specialized process that raises many important questions when selecting a manufacturing partner. Below are answers to common inquiries we receive from OEMs and engineers.
Swiss screw machining offers greater precision and stability, especially for small or slender parts. Unlike traditional CNC lathes, Swiss machines guide the workpiece through a guide bushing, reducing deflection and allowing tighter tolerances.
Our Swiss screw machining equipment can maintain tolerances as tight as ±0.0002 inches, depending on the material and part design. This level of accuracy supports critical applications in medical, aerospace, and electronic assemblies.
This process is ideal for high-volume, precision cylindrical components such as spacers, shafts, connectors, screws, pins, and bushings—especially when the design includes fine features or long, slender shapes.
Yes. While Swiss screw machining excels at high-volume production, we also support short-run and prototype projects depending on complexity and timeline. Our in-house team will help determine the most efficient path to production.
We are ISO 9001:2015 certified and ITAR registered. Our quality systems, material traceability, and inspection processes meet the demands of regulated industries like aerospace, medical, and defense.
