Need very smooth I.D. of OFE Copper tubing
2007
My application requires less than 4 micro inch Ra finish of the inner surface of the copper tubing. (OD 6 mm, ID 5 mm, 12 ft long, OFE copper)
Does any tubing supplier provide this level of surface finish?
What kind of finishing process can help to achieve this surface roughness of the inner surface of commercially available drawn copper tubing (12~14 micro inch Ra based on the drawn copper tubing sample)?
Any comments are welcomed.
