Abstract
The efficiency of the grinding wheel is reduced due to the use in the manufacture of grains with
arbitrary shape and random orientation. It is proposed to improve the performance of grinding
wheels due to the target bean in their body. Describes the experimental design of grinding wheel,
which is composed of grains oriented with the electrostatic field. The experimental range is tested in
a comparative test with a standard circle on a special stand mounted on the base of the grinding
machine model 3G71. The results of the tests, the main content of which is that the performance of
grinding wheels can be significantly improved by a differentiated approach to the choice of the
shape and orientation of the grains used in their manufacture.
