Finish requirements on machined components have become a big concern for OEM’s around the world. The smoother the surface the higher the price, the reason for this is because manufacturing is slowed down. Not only does the machining process slow down, but inspection time also increases. When designing your component keep in mind to only require what is needed to make the part function. Sometimes a call-out for a smooth surface finish does not guarantee that the part will last longer or seal better.
