What Is Swiss Turning?
Swiss turning uses a sliding headstock lathe where the bar stock feeds through a precision guide bushing — a bore that supports the workpiece directly at the cutting point. As the bar advances, the guide bushing moves with it, maintaining continuous support regardless of how long or slender the part is.
This is the fundamental difference from standard CNC turning — the workpiece is always supported where the tool cuts, eliminating deflection, vibration, and the dimensional errors they cause.

Why Swiss Turning for Petits composants de précision
Standard CNC turning breaks down on small, slender, high-volume parts. Swiss turning was built precisely for these.
↔
No Deflection on Long Slender Parts
Slender parts deflect under cutting force on a conventional lathe — causing vibration, taper, and inconsistent finish. The Swiss guide bushing eliminates deflection at the source, enabling parts with L/D ratios up to 100:1 that would be impossible to turn accurately any other way.
Ra
Superior Surface Finish on Small Diameters
Swiss turning consistently achieves Ra 0.4 μm and below on small-diameter parts. Stable workpiece support, minimal vibration, and short tool reach produce a finish quality that is difficult to match on small features with standard turning.
±
Tight Tolerance on Micro Features
Medical cannulas, dental implant bodies, and connector pins require ±0.005 mm and below on diameters measured in fractions of a millimeter. Swiss turning delivers this repeatably — across thousands of parts — because workpiece stability is built into the process itself.
HV
Built for High-Volume Repeatability
Bar-fed Swiss lathes run lights-out with consistent cycle times and stable process parameters. Ideal for recurring production of small precision components — the same quality, same dimensions, and same cost on the 50,000th piece as the first.

FAQ
Foire Aux Questions
All you need to know about Swiss turning — what it is, when to use it, and how it differs from standard CNC turning.
Le tournage suisse est un processus de tournage CNC de précision effectué sur un tour de type suisse, où une tête de fixation glissante alimente la barre d'alimentation à travers un guide-bouton qui supporte directement la pièce à l'endroit de l'usinage. Cela permet l'usinage de pièces de très petit diamètre, longues et fines sans déviation de la pièce, offrant une précision dimensionnelle supérieure et une finition de surface meilleure par rapport au tournage CNC conventionnel pour les composants de petit diamètre.
Les pinces de tournage CNC standard bloquent la pièce dans un mandrin et usinent d'une extrémité, limitant les rapports L/D pratiques à environ 5:1–10:1 avant que la déflexion ne devienne un problème. Le tournage suisse fait passer la barre à travers un manchon guide qui la soutient à quelques millimètres du point de coupe, permettant des rapports L/D allant jusqu'à 100:1 sans déflexion. Le tournage suisse est le procédé approprié pour des diamètres de Ø0,5 à 32 mm ; le tournage CNC standard couvre des diamètres plus grands jusqu'à Ø600 mm.
Le tournage Swiss est optimisé pour des diamètres de barre allant de Ø0,5 mm à Ø32 mm, avec des rapports longueur/diamètre allant de 5:1 à 100:1. Les pièces de diamètre supérieur à Ø32 mm doivent utiliser le tournage CNC standard.
On a conventional CNC lathe, slender workpieces bend under cutting forces, causing vibration, dimensional error, and poor surface finish. Swiss turning's guide bushing supports the bar at the exact cutting point at all times — the workpiece cannot deflect regardless of length.
Nous utilisons l'acier inoxydable (303, 304, 316L, 17-4PH), le laiton (C360, C260), l'aluminium (6061, 7075), le titane (Grade 2, Grade 5/TC4), le cuivre et les plastiques techniques (PEEK, Delrin/POM, PTFE) sur nos tours de tournage suisse. Les grades à coupe facile comme l'acier inoxydable 303 et le laiton C360 sont préférés pour la production en grande série en tournage suisse en raison d'un excellent contrôle des copeaux.
Yes. Swiss turning is the primary production process for medical small-diameter components — cannulas, bone screw blanks, surgical pins, catheter parts, and implant-adjacent hardware. For electronics, Swiss turning produces micro connector pins, terminal contacts, and sensor components at the volumes and tolerances required by medical and electronics OEMs.
Yes. Swiss lathes with bar feeders run unattended for entire shifts. Stable cycle times, fast bar changes, and in-process gauging make Swiss turning the ideal platform for 10,000-piece to 500,000-piece production runs.
Our Swiss turning capacity covers Ø0.5 mm to Ø32 mm. For parts above Ø32 mm, please refer to our CNC Turning Service which handles outer diameters up to Ø600 mm.
