The proposed composition of solid technological lubricant applied to the working
surface of the abrasive wheel directly in the grinding process. Experimental studies have been
carried out to identify the effect of implanting on the normal and tangential components of the
cutting effort and temperature that occur when grinding with abrasive wheels with continuous
and intermittent work surfaces. It is established that when grinding with impregnated
intermittent circles, the magnitude of the ratio Fz
/Fy normal to the tangential component of the
cutting force is less than when grinding with impregnated wheels with a solid working surface.
It was established experimentally that the impregnation of the working surface of intermittent
wheels reduces the thermal stress of the grinding process and increases the number of actively
working grinding grains. The decrease in the Fz
/Fy ratio during intermittent grinding with an
impregnated wheel compared to dry intermittent grinding can be explained by a decrease in Fz
with a simultaneous increase in Fy. A decrease in temperature when using solid lubricant
indicates a decrease in the coefficient of friction of grinding grains with the processed material
and, therefore, a decrease in the tangential component of the cutting force Fz
. An increase in
the number of actively working grains during grinding with intermittent impregnated circles
compared to dry intermittent grinding indicates an increase in the normal component of the
cutting force Fy. It is established that the maximum temperature during grinding with
impregnated intermittent circles shifts towards the rear point of the contact arc compared to dry
grinding, where the temperature reaches its highest value near the front point of the contact arc
of a circle with the material being processed.
