Swiss-Style CNC Turned C36000 Brass Small Parts
These are small precision brass parts made by Swiss-type style CNC turning from C36000 free-cutting brass, such as contact pins, bushings, carburetor jets, sensor pins and miniature fasteners. Swiss-style turning supports the bar close to the cutting tool, holding tight diameters on long, slender parts. They are made for electronics and instrumentation buyers needing accurate small parts in volume.

Manufacturing
How we make this part
Process, material options and inspection for swiss-style cnc turned c36000 brass small parts.
On a Swiss-style lathe, the bar moves through a guide bushing while the tool cuts right next to it, so the part is always supported near the cut. That prevents deflection on long, thin parts such as pins and probes. Sub-spindles finish the back side and live tools add cross holes, flats or slots, so even complex small parts come off the machine complete.
C36000 brass is the benchmark for machinability, giving clean chips, long tool life and fine surface finishes. It conducts electricity well, making it a common choice for pins and contacts. Plating options include nickel for corrosion resistance and tin or gold-type coatings for solderability and contact reliability. For lead-free requirements, alternative brass grades can be used.
Diameters and lengths are measured with micrometers and optical comparators, and thread fits are checked with gauges. Critical dimensions are inspected on every batch, with documented sampling plans for larger production runs and full checks on critical features. Typical parts include PCB contact pins, connector sockets, carburetor jets, miniature bushings, spring-probe barrels and watch or instrument components.
FAQ
Frequently asked questions
When should I use Swiss-style turning instead of a normal CNC lathe?
Use Swiss-style turning for small, long or slender parts, generally where length is several times the diameter, and for repeat batches of small parts. The guide bushing supports the bar near the cut, preventing deflection. Larger or short, stubby parts are usually more economical on conventional CNC lathes.
What plating is best for brass contact pins?
Nickel underplate with a gold-type finish is common for low-resistance, high-cycle contacts. Tin plating is cheaper and solders well for fixed connections. Plain nickel offers good corrosion resistance where contact resistance is less critical. Specify plating thickness on the drawing.
