Researches of Surface Quality Parameters of High Speed Sliding Bearings from Composite Materials for Printing Machines at DIamond Grinding

In the article the research results of defect layers formation on surface of high-speed sliding bearings made of new high-alloy composite materials from tool steels wastes and intended for printing machines have been presented. Such quality parameters of surface like cold-work strengthening and distortions of the 2-nd type are supplied by the result of interaction between force and temperature fields appearing on the top of diamond grain at fine diamond grinding of friction surfaces of sliding bearings were shown.

Effect of Diamond Honing Technological Factors for Parameters of Roughness and Exactness of Composite Sliding Bearings Surfaces for Printing Machines

In a paper the research results concerning an influence of honing process’ technological factors such as abrasive tool composition, cutting parameters, number of hones in honing head on surface roughness and surfaces’ exactness of new composite sliding bearings manufactured of new high-alloy composite alloys from tool steels wastes for high-speed printing machine have been presented.
