CNC Swiss Machining
Resolute Precision Manufacturing operates six Swiss CNC machines in 20mm, 32mm, and 38mm sizes, producing highly complex small-diameter components for medical device, fluid power, aerospace, automotive, and fastener manufacturers. Our Swiss CNC machining capabilities allow us to produce Swiss machined parts with threading, grooving, cross-drilling, and milling completed in a single uninterrupted cycle. For manufacturers seeking reliable Swiss machining services, we provide finished components directly to you with no distributor markup. Request a QuoteWhat Makes Swiss CNC Machining Different?
Swiss-type turning uses a guide bushing positioned directly at the cutting zone to support the workpiece as it feeds through the machine. Unlike conventional lathes, where the part is clamped at one end and may deflect during cutting, the guide bushing keeps the workpiece stable at the exact point where material is being removed. This provides exceptional dimensional consistency for long, slender, and small-diameter Swiss machined parts that can be difficult to produce accurately on a conventional lathe.
Our Swiss CNC machining process incorporates multiple operations OD turning, ID boring, threading, grooving, cross-drilling, and live milling into a single uninterrupted program. This reduces secondary operations, re-fixturing, and the potential for setup-related variation between features. The result is a completed part ready for inspection and shipment.
Our Swiss machining services are designed for manufacturers requiring precision, repeatability, and efficient production of complex small-diameter components.
Our Swiss CNC Machine Sizes
We operate Swiss CNC machines in three capacity classes, matching machine size to part requirements for optimal efficiency and precision.
- 20mm Swiss CNC — Fine small-diameter components such as pins, micro-fasteners, and miniature valve components
- 32mm Swiss CNC — Mid-range production for fittings, fasteners, valve spools, and other precision components
- 38mm Swiss CNC — Largest Swiss capacity for more substantial cross-sections while maintaining the precision advantages of Swiss machining

Typical Swiss Machined Parts
Swiss CNC machining is ideal for parts that are long relative to their diameter, require tight tolerances, and need multiple features completed in a single cycle. Common Swiss-machined parts from Resolute Precision include:
- Medical devices: Implant screws, instrument components, cannulas, surgical fasteners
- Fluid power: Valve spools, metering pins, poppets, hydraulic fittings
- Aerospace and defense: Lightweight aluminum and titanium structural fasteners
- Automotive: Injector components, sensor housings, threaded inserts
- Electronics: Connector pins, contact bodies, precision housings
- Custom fasteners: Specialty screws, socket head cap screws, precision bolts
Frequently Asked Questions
What is the bar stock diameter range for RPM's Swiss CNC machines?
Our Swiss machines handle bar stock from approximately 1mm to 38mm (1-1/2 inches) diameter. For parts larger than 38mm, our conventional CNC lathes with live tooling provide comparable complexity capability.
How does Swiss machining compare to conventional CNC turning for small parts?
Swiss machining supports the workpiece at the cutting zone via a guide bushing, virtually eliminating deflection. Conventional lathes clamp at one end — parts under 1/2 inch diameter in long lengths will deflect during cutting, degrading accuracy and surface finish.
What tolerances do RPM's Swiss CNC machines achieve?
Our Swiss machines routinely achieve tolerances of ±0.0005″ or tighter. For critical diameter and length dimensions, even tighter tolerances are achievable with appropriate process controls.
Does RPM produce Swiss-machined prototypes?
Yes. We produce Swiss-machined parts from single-piece prototypes through high-volume production runs. Prototype and production use identical machines and processes, ensuring your prototype accurately represents production part quality.
