Small Precision Components
Small precision components are miniature machined parts, often under 10 mm in size, such as pins, nozzles, contacts, screws and instrument parts, held to fine tolerances. They need sliding-head (Swiss-type) or precision lathes, careful tooling and gentle handling.
What it is
Tiny parts are commonly turned on sliding-headstock (Swiss-type) CNC lathes, where the bar is supported right next to the cutting tool. This keeps slender parts from deflecting and holds tight diameters along their length.
Burr control, cleaning and handling matter as much as machining: small parts are deburred carefully, washed, and packed to prevent damage and mixing.
Typical applications
- Electrical and electronic contacts
- Nozzles, jets and orifices
- Watch, instrument and meter parts
- Medical and dental components
- Micro pins, shafts and screws
Suitable materials
- Brass (free-cutting)
- Stainless steel (303, 304, 316)
- Phosphor bronze and copper
- Aluminium
- Plastics such as POM and PEEK
Points to consider
- Free-machining grades (such as CZ121 brass or 303 stainless) machine faster and cleaner on small parts.
- Very small holes and threads (below about M1.6) limit material choice and tool life; discuss early.
- Specify cleanliness and packing needs for electronics or medical parts.
- Batch quantities matter; sliding-head lathes are most economical from a few hundred pieces upward.
Frequently asked questions
What is Swiss-type turning?
A sliding-headstock CNC lathe that feeds the bar through a guide bushing so cutting always happens close to support. It is ideal for long, slender and very small precise parts.
What is the smallest part you can supply?
Parts down to around 0.5 mm diameter are routine on suitable machines. Share the drawing and we will confirm the best route.
How are small parts protected in delivery?
They are deburred, cleaned and packed in trays, bags or separators as required, so they arrive clean and undamaged.
