The working surface of a component has a direct relationship with mechanical contact. Burrs, rough areas or inconsistent finishing can increase friction or interfere with smooth movement.

For precision sewing components, appropriate finishing can help create more predictable interaction between mating parts. This is particularly relevant for components that move continuously during sewing.

A supplier with controlled machining and finishing processes can provide greater consistency than a supplier that focuses only on basic dimensional compatibility.
