Swiss-type turning for small-diameter precision components.
Swiss-style turning supports small-diameter parts with tight concentricity, repeatable surface finish, and long-running production cycles. Common applications include medical components, electronics hardware, and fluid system parts.

Engineering FAQs
The questions engineering and procurement teams ask most often before a first quote.
What's the maximum bar diameter?
20 mm. For diameters above 20 mm, parts move to the Mazak or Okuma turning centers.
Are Swiss parts suitable for medical applications?
Yes — Swiss turning is widely used for medical components. Material lot control and traceability are available for qualified programs.
Do you offer secondary finishing?
Yes. Common secondaries include grinding, deburring, and outsourced surface treatments such as passivation or anodizing.
What's a typical Swiss production run size?
Anywhere from a few hundred to many thousands of pieces. Volume affects setup amortization — discuss your expected annual volumes at RFQ.
