Finishing of aluminium alloy flat products

Abstract

The possibility of improving the surface quality of flat products made of aluminium alloy AMc is considered by using the method of magnetic abrasive processing in the finishing stage of manufacturing. The influence of the main technological parameters of magnetic-abrasive processing, temperature factors and the composition of the cooling lubricant on the quality of the processed surface has been investigated. The results obtained from experimental studies have shown significant improvements in surface quality, which allow us to conclude on the effectiveness of the magnetic abrasive blasting method for finishing products made of the AMc aluminium alloy.
