Stainless steel thin wall parts Product Name: stainless steel thin wall parts Material: SUS430 Product requirements: outer diameter 23.0mm, wall thickness 0.4 + / - 0.015mm, requirements: parallelism 0.03, perpendicularity 0.03, concentricity 0.015, bright surface of outer end face. Product features: thin wall, easy to deform during cutting; The clamping force of the fixture is large, the end face will bulge out, and the clamping force is small, and the product cannot be clamped; The shaving tool has small tip arc, non bright surface, large tip arc, large turning resistance, out of tolerance parallelism and other technical difficulties Our solution result: 0.4 wall thickness can meet the dimensional tolerance requirements. We control the parallelism within 0.01, perpendicularity within 0.015, flatness within 0.015, concentricity within 0.01, and the surface brightness also meets the customer's requirements. Wall thickness we have a challenge to 0.28 + / - 0.02
