Opis:: The purpose of this research is to asses the functionality of surfaces produced by CBN hard turning, ball burnishing and superfinishing for improving the surface finish of parts made of high-strength, low alloy 41Cr4 steel with a hardness of about 57 HRC. Machined surfaces were characterized usin 3D scanning techniques. A set of 3D roughness parameters and real 3D surface topographies produced by the above-mentioned machining operations were estimated and determined.This investigation confirms that sequential processes based on initial CBN hard turning allows producing surfaces with better service properties.The main conclusion is that this sequential technology can partly eliminate grinding operations when hard machining is not enough to produce the desired surface finish.

Opis:: The purpose of this research is to test the applicability of ball burnishing for improving surface integrity produced in hard machining on parts made of high-strength, low alloy 41Cr4 steel with hardness of about 57 HRC. Machined surfaces were characterized using 2D and 3D scanning techniques. Moreover, the distribution of microhardness beneath the surface was determined and the microstucture of the sublayer was examined using SEM/EDS technique. This investigation confirms that ball burnishing allows producing surfaces with acceptable surface roughness and better service properties. The main conclusion is that this sequential technology can partly eliminate grinding operations when hard machining is not enough to produce the desired surface integrity.

Opis:: This paper characterizes mechanical properties of the technological subsurface layer produced by medium milling of EM AW-AlCu4MgSi(A) aluminium alloy in hardened state T451 using a ball-end cutter and subsequent roller burnishing using a nitride ceramic ball. It was revealed that ball burnishing operations performed on curvilinear milled surfaces allow obtaining the subsurface layer with a minimum strain-hardening effect and induced compressive residual stresses without visible microstructural changes. As a result, such functional properties of the subsurface layer as fatigue strength, bearing properties and contact strength along with a very smooth machined surface of the Sa roughness of about 0.02 µm can be ensured.

Opis:: This paper characterizes surface topographies produced by medium milling of EM AW-AlCu4MgSi(A) aluminium alloy in hardened state T451 using a ball-end cutter of 8 mm diameter and subsequent finish by roller burnishing using a Si3N4 nitride ceramic ball of 8mm diameter. It was revealed that ball burnishing operations performed on curvilinear milled surfaces allow obtaining the machined surfaces of high quality and exceptional smoothness with different textures and, as a result, ensuring demanded functional properties such as fatigue strength, bearing properties and contact strength [1]. It was experimentally verified that precision ball burnishing performed with a low stepover of 0.04mm produced a very smooth with the Sa roughness of about 0.02 µm characteristic for polishing.
