Swiss Machining: What Small, Long and Complex Precision Parts Can You Produce?

From our historical RFQ data, around 70% of incoming part requests fall within 1–100 pieces. We support both prototype batches and volume production with no minimum-order requirement. Submit your drawing for feasibility evaluation.

Typical Parts We Machine on Swiss-Type

Real demand from our RFQ inbox — long slender and small-diameter parts are among the most frequent requests we receive for Swiss-type work, mostly for connectors, instruments and precision hardware.

• Long slender shafts and small-diameter pins
• Fasteners and threaded precision hardware
• Connector pins and instrument components

Frequently Asked Questions

• What is Swiss machining?

  A turning method where bar stock feeds through a guide bushing so the tool cuts close to the support point. This eliminates deflection on long, thin parts — the reason Swiss-type machines are the default for small, slender components with tight tolerances.

• When is Swiss machining better than standard turning?

  For parts with a high length-to-diameter ratio (roughly above 3:1) and small diameters, standard turning centers cannot hold accuracy because the workpiece deflects under cutting force. Swiss machining supports the material within millimeters of the cut and holds the tolerance without chatter.

• What tolerances can Swiss machining hold?

  ±0.005 mm on critical diameters, verified on a CMM with a full report. General dimensions run at ±0.05–0.1 mm unless specified.

• What materials can be Swiss-machined?

  Aluminum 6061/7075, stainless 303/304/316, Ti-6Al-4V, brass, and engineering plastics such as PEEK and POM. Small diameters in these materials are routine for connector and instrument components.

• What batch sizes suit Swiss machining?

  Swiss-type capacity runs from pilot quantities to high-volume production — the process is stable across long runs, which is why it is standard for connector pins, fasteners and instrument parts.

• How do I get a feasibility check for my part?

  Send your drawing or STEP file — we review the diameter, length and features within 48h and confirm whether Swiss machining is the right process before quoting.
