On Modelling and Experimental Verification of Micro-Smoothing Process in Extra Low Temperatures

Particularly good results in micro-smoothing of steel work-pieces surfaces by means of imperial micro-finishing films, and difficulties in obtaining proper machining effects for aluminium and its alloys and also for other high plasticity materials in surrounding temperature, have caused examining of this process in extra low temperatures. Carrying out the process in extra low temperature, and at the same time in vacuum, makes it possible to obtain extra smooth surfaces of elements made from aluminium. The paper presents the experimental stand which is adapted for operations in extra low temperatures and results of micro-smoothing processes.
