Swiss Turning Parts Buyer Checklist
- Specify critical-to-function dimensions in the drawing — diameter, length, concentricity, and surface finish
- Define material grade and condition material selection affects tooling, surface finish, and unit cost
- Confirm secondary operations heat treatment, plating, thread rolling, or assembly requirements
- Share annual volume estimates high-volume runs benefit from dedicated tooling and dedicated production lines
- For tight tolerance components, review inspection method and sampling plan during quotation

FAQ
What is Swiss turning and why is it used for precision parts?
Swiss turning uses a sliding headstock and guide bushing to support the bar stock close to the cutting tool. This enables tight tolerances on small-diameter parts (typically under 25 mm) with minimal deflection, making it ideal for connector pins, medical needles, and miniature turned components.
What tolerances can VOLCRIX hold on Swiss turned parts?
±0.01 mm on critical diameters and ±0.005 mm on premium applications. Concentricity is typically held to 0.01 mm TIR or better, verified on Zeiss CMM.
What materials can be machined on Swiss turning machines?
Stainless steel (303, 304, 316, 17-4PH), brass (C36000, C26000), copper (C11000, C18150), aluminum (6061, 6063), titanium, and engineering plastics including PEEK and Delrin.
What is the minimum order quantity for Swiss turned parts?
VOLCRIX supports prototype runs as low as 100 pieces and high-volume production above 1 million pieces annually, all on the same Swiss turning platform.
