Material machining for friction knots of moving parts for agricultural machines

Žitňanský J., Žarnovský J., Mikus R., Kovac I., Andrassyova Z., 2011. Material machining for friction knots of moving parts for agricultural machines. Res Agr. Eng., 57 (Special Issue): S61–S68. The study deals with the effect of the cutting parameters such as the cutting speed, feed and cooling on the quality of machined surfaces in the process of hole drilling for the sliding bearings used in agricultural technique. This effect has been studied on various metals such as copper, brass, dural and leaded bronze, which are commonly used for their friction knots of the moving parts for agricultural machinery. The results suggest the use in the design of collection parts, scything strips, as well as lifting equipment of agricultural technique, where particular linear and rotary movements of the friction parts are slow, as well as for the design of appropriate drilling procedures.
