Abstract

The article considers the issues of increasing the efficiency of profile grinding of gears based on the use of tools made of mono-corundum of various types. Experimental studies of the gear grinding process were carried out on a HÖFLER RAPID 1250 gear grinding machine. Evaluation of the performance of grinding wheels was carried out according to the power of grinding and the accuracy of processing gears.
The analysis of the grinding results showed that the effective grinding power of gears when machining with mono-corundum wheels is 2 times lower than with white electrocorundum wheels and 1.5 times lower than with chromium electrocorundum wheels.
It was found that after gear grinding with mono-corundum wheels, gears corresponding to the 2nd class of accuracy are obtained.
