Swiss CNC machining, also known as Swiss turning or Swiss screw machining, uses a sliding headstock lathe where the workpiece moves along the Z-axis while tools remain stationary. This provides exceptional support near the cutting point, enabling ultra-precise machining of small diameter parts with length-to-diameter ratios up to 20:1.
Swiss CNC machines typically handle parts from 0.060" to 1.25" in diameter, with lengths up to 12". Some machines can work with diameters as small as 0.020" for micro-machining applications. The guide bushing support allows for extremely long, slender parts without deflection.
Swiss turning excels at small diameter parts (under 1.25"), long slender parts, and high-volume production. The guide bushing provides superior support, enabling tighter tolerances and better surface finishes. Conventional turning is better for larger diameters and shorter parts where the guide bushing isn't needed.
Swiss machines excel with free-machining materials like brass, aluminum, and 12L14 steel. They also handle stainless steel (303, 316), titanium, plastics (Delrin, PEEK), and exotic alloys. The key is using materials that produce good chip control for the narrow chip evacuation channels.
While Swiss machines are optimized for high-volume production (10,000+ parts), many shops accept smaller quantities. Minimum orders typically start at 100-500 pieces, though some shops offer prototype quantities of 25-50 parts. Setup costs are amortized better over larger runs.
