Screw/Swiss machined parts often have very small features called micro-features. Screw/Swiss style machines are similar to CNC lathes or turning centers, only on a smaller scale. Screw/Swiss turning machines are often faster and more accurate than traditional CNC turning centers. The ideal parts for Screw/Swiss turning are made from stainless steel, titanium, brass, aluminum, platinum and iridium. NOTE: Low volume turned parts should be categorized under machining-turning.
