The burnishing process of the stainless steel in aspect of the reduction roughness and surface hardening
In the article were presented influence of technological parameters of burnishing process on the degree of
hardness and reduction roughness. Burnishing process carried out for stainless steels X2CrNiMo17-12-2. The
experimental research were obtained in the surface layer increase in hardness and the material ratio curve a convex
shaped, which, taking into account the load capacity of the surface will be directly affected by its resistance to wear
and corrosion. The experimental research by application of the burnishing rolling – pressuring process (BRP) method
were made in the Laboratory of Production Engineering at the Department of Marine Maintenance at the Faculty of
Marine Engineering at the Gdynia Maritime University. After the studies it was found that the hardness of the surface
layer and the roughness of the shaft necks an important influenced by technological parameters of processing
(burnishing speed, feed and depth of burnishing). The objective of applying burnishing process may be, for example,
the need to increase surface smoothness and dimensional accuracy of part. To achieve the objectives strengthen and
smooth of burnishing stainless steel should be used the one pass burnisher roller and feed fn = 0.2 mm/rev and disk
burnishing tool feed an = 1.0 mm and burnishing speed vn = 70 m/min.
