Abstract

The properties of porous permeable lubricating elements fabricated from sintered metal powders were studied. It was shown that the working properties of the material are determined by its pore structure. Tests on type V TS-07/2 twisting machines revealed that the newly developed lubricating elements increase the degree of lubrication ten fold, and decrease thread breakage by 13–30%. Use of these elements permitted an increase in spindle rotation rate, leading to a 7–9% increase in machine productivity, and also decreased the extent of dusting by 57–76%.
