The Friction and Wear of Plastics, with Special Reference to Machine Tool Slideways
A range of plastics have been tested under conditions simulating those commonly encountered on machine tool slideways. The resultant information is assessed, together with published data, to enable specific design recommendations to be promulgated. Aspects considered include the effect of velocity, load, and sliding distance on friction and wear.
It is suggested that a bronze-filled PTFE composite is likely to give good compromise between friction and wear when employed on machine tool slideways under dry conditions. In the lubricated state, the main function of such material would be to provide a backup in case of lubricant failure.
