Abstract
This paper introduces some results of the researches that the authors conducted in the field of using plastic materials for plating the surfaces of the guideways for heavy duty machine tools. There are mentioned theoretical aspects about the calculation and selection of these guideways and the results of the experimental researches performed on the occasion of the remanufacturing of a rotary table intended for the machining on two axes of large mass and overall size workpieces, specific to heavy industry. It is also shown the technology of assembling and machining the plates made of plastic materials. It is about the translational sliding guideways and about the rotational guideways too. They operate with intermittent, continuous or hydrostatic lubrication. The research results can be also applied in the case of remanufacturing of other heavy duty machine tools such as: standard or vertical lathes, Gantry type milling machines, grinding machines or table type HBM-s and floor type HBM-s etc.
Keywords: guideways; plastic materials; heavy duty machine tools; manufacturing; remanufacturing
