Frequently Asked Questions About Swiss Machining
Swiss machining uses a guide bushing to support material close to the cutting tool, reducing deflection and allowing for higher precision on small parts. The material moves through the guide bushing while cutting tools work on the portion outside the bushing. This design helps make small, complex parts with tight tolerances and excellent surface finish.
Our Swiss machines typically work with material diameters from 0.5mm (0.020") up to 32mm (1.26"), with common sizes between 3mm (0.118") and 20mm (0.787"). Maximum part length depends on the specific machine, but we can machine parts up to 1,200mm (47.24") long.
Our Swiss machining operations typically hold tolerances as tight as ±0.0001" (0.0025mm) on diameter dimensions. For length dimensions, we typically keep tolerances of ±0.001" (0.025mm) or better depending on part geometry.
We machine many materials on our Swiss lathes including stainless steel, carbon steel, alloy steels, aluminum alloys, brass, bronze, titanium, and superalloys like Inconel and Monel. Our material knowledge covers both common and exotic metals for demanding applications.
Swiss machining works best for small, precise parts that have:
- Small diameters (typically under 1.25")
- Tight tolerances
- Complex features or geometries
- Need for excellent surface finish
- Long length-to-diameter ratios Common examples include precision fasteners, medical device components, electronic pins/connectors, and small hydraulic fittings.
Swiss machines can run multiple tools at once, perform front and back operations in one setup, and use continuous bar feeding for unattended operation. This design cuts cycle times, reduces setup needs, and improves part consistency compared to conventional turning.
Multi-axis Swiss machines (like our 8-axis Citizen L32) can perform complex milling, drilling, and contouring operations without moving parts between machines. This helps keep tight tolerances, reduces handling damage, and cuts overall production time.
Yes, we provide detailed inspection reports showing critical dimensions and features. For aerospace and other high-reliability components, we offer complete First Article Inspection Reports (FAIRs) meeting industry standards.
Our Swiss machines use 12-foot bar feeders that automatically feed material into the machine. This system allows for continuous production with minimal operator intervention. The bar feeders work with our Swiss machines to keep tight diameter tolerances throughout the bar length.
Yes, we coordinate many secondary operations including heat treating, plating, anodizing, passivation, and other surface treatments through our Outside Process Management services. This gives you one point of contact for complete, ready-to-use components.
