A STUDY OF THE PLASTICS COATINGS USED ON PLAIN SLIDEWAYS OF MACHINE TOOLS Heber Ferreira Franco de Castro
Resumo: In this paper, several types of plastics for facing machine tool slideways are described. They are the ones based on PTFE, epoxi and acetal resins. Tribological, mechanical and chemical properties of these coatings as well as their methods of application on plain slideways are described. The stick-slip motion which may occur on plain slideways is discussed. This article also presents an application of PTFE-Zerodur slideway for nanometric positioning system.
