The paper reports the study of peculiarities in the roughness formation of conjugate cylindrical and end surfaces of machinery at their simultaneous grind-ing with the disk periphery and the end. The analytical dependences for the computation of altitude and step parameters of surface roughness at simultaneous grinding with disk periphery and butt are obtained the authenticity of which is confirmed in the course of experimental investigations. It is defined that altitude and step roughness parameters of cylindrical surfaces and end surfaces conjugate with them after their simultaneous grinding may differ up to 2-3 times. Lesser roughness is formed on end surfaces which is explained by the large number of disk grain tips contacting with given surfaces of a blank. The roughness step parameters of ground surfaces are influenced considerably by a rounding radius of abrasive grain tips at that the average step of unevenness along a middle line Sm is threefour times greater than the average step S on tips. It is shown that a considerable impact of abrasive tool characteristics and time of surface processing with a grinding disk upon parameters of roughness in conjugate surfaces of parts. Recommendations scientifically substantiated are formulated on the technological support of surface roughness parameter aggregate at simultaneous grind-ing with the disk periphery and the end.
