Abstract

Modern applications of pneumatic and hydraulic systems in extreme subsea production increased emphasis on long life and minimum maintenance cycles. For this reason, are constantly developed new sealing elements. These sealing elements require very low surface roughness at the contact surfaces. High geometrical and dimensional accuracy is not required because the inaccuracies are compensated by sealing elements. The aim of this paper is to propose a production technology that can achieve the surface roughness Ra = (0,1 ÷ 0,4) µm and geometric accuracy H11. Machined material is chrome-nickel austenitic stabilized steel F304L according to EN 10088-3 marked 1.4307. This article includes applications of ball diamond finishing machining to turning surface. Appropriate technological conditions have been established. These conditions correspond to the specified surface roughness criterion.
