- Abstract
Annotation: The purpose of work is the experimental researches of fine elbor grinding of friction parts from new composite materials based on aluminium alloys wastes for machine complexes of light and food industries enterprises and also for printing equipment. Methodology. The samples were processed on plain-grinding, round-external-finishing and internal-grinding machines. Fine elbor grinding was carried out by grinding discs from elbor on bacelit-gum bond. The samples were manufactured by powder metallurgy from composite alloys based on aluminium alloys wastes, such ass AK12M2MƱH, AM4,5KД AK8M3ч and AK12MMƱH + (9-12%) MoS2. Findings. It was demonstrated the tool granulosity, elbor disc's material of bond and fine elbor grinding parameters essentially influence for surface's parameter Ra. Grinding discs from elbor Л with granulosity 14-28 µM on bacelit-gum bond and fine parameters of cutting ensure the best value of parameters Ra which satisfy the high requirements for technological complexes and machine systems' friction parts surface quality. It was shown the advantages of surfaces' treatment by elbor discs. Originality. For the first time it was shown the main regularities of fine precision elbor grinding of new composite materials based on aluminium alloys wastes agree with plain, round external and internal grinding. Practical value. It was developed the recommendations for choice of cutting parameters for elbor grinding of parts for different purposes that are manufactured from composite alloys based on aluminium alloys wastes and which ensure the requirements for necessary parameters of surface roughness.
