Surface finish and polishing of manifolds
By: Tom Rohlfs
GETTING STARTED WITH MANIFOLD DESIGN Our standard surface finish is a maximum of 32 microinch RA (.8 micrometer RA). We will finish all surfaces to that roughness unless otherwise stated. Flat areas: We can finish areas of large flat surfaces to an optical finish below 4 microinch RA (0.1 micrometer). Valve mount surface finish is maximum 32…
