Swiss Machining Service
Our precision swiss machining services surpass standard CNC turning. The Swiss screw machine design enables ultra-tight tolerances by feeding bar stock through a guide bushing while stationary tools cut very close to the support point, delivering exceptional accuracy and finish for small, complex parts like surgical instruments, connectors, and aerospace components.

FAQs
What is Swiss machining, and how does it differ from standard CNC turning?
Swiss machining (also called Swiss-type or Swiss screw machining) uses a specialized CNC lathe with a guide bushing that supports the bar stock close to the cutting tools, minimizing deflection and vibration. This allows for ultra-high precision on small, slender, or complex parts in a single setup, unlike conventional CNC turning where longer stock exposure causes more deflection and often requires secondary operations.
What tolerances and part sizes are achievable with Swiss machining?
Tolerances routinely reach ±0.0001″ to ±0.001″ (or even tighter in controlled conditions), far superior for slender or small-diameter parts compared to standard methods. Typical part sizes focus on diameters from about 1mm to 32–38mm (up to ~1.25–1.5″), with lengths often up to several inches (or more with high L/D ratios), making it perfect for miniature to small precision components.
What are the typical part size ranges for Swiss machining?
Focused on small to medium parts: diameters from ~1mm to 32mm (up to 1–1.25″ max on many machines), lengths up to 8–12″ or more per chucking (e.g., long slender shafts up to φ32×950mm in some cases). Excels at high length-to-diameter ratios.
Is Swiss machining suitable for prototypes, small batches, or high-volume production?
Toggle Conten
Yes—all quantities work. It often excels with smaller runs, prototypes, or short lead times due to efficiency and automation, but also supports high-volume via bar feeders and lights-out operation for consistent, cost-effective medium-to-large batches.
t
What operations or capabilities are included in Swiss machining services?
Multi-axis (up to 7–8+ axes) turning, milling, drilling, boring, threading, slotting, knurling, grooving, tapping, C-axis indexing, live tooling, sub-spindles for simultaneous front/back operations, and more—all in one setup to minimize handling.
What factors affect lead times, costs, or quoting for Swiss machining?
Lead times vary (e.g., 1–10 days for small batches, faster for prototypes); costs benefit from small/medium runs and reduced secondary ops. Quotes typically require CAD drawings (2D/3D), material specs, surface treatments, quantity, and delivery needs. Certifications (ISO 9001, AS9100, etc.) and automated quoting are common.
