The article presents the results of research on the grinding of the technological grinding of the tooth surface of toothed wheel cylinders. The toothed teeth with straight teeth, modules m = 2÷6 mm, bore width b = 26÷94 mm, number of teeth with z = 12÷48 made of 40H and 12H2N4A steel with a hardness of 60 HRC. For grinding, T1Q grinding wheel has the following parameters: D = 350 mm, H = 25 mm, δ = 140°, grains 99A, grain size 60, hardness H, structure 5, binder V. The results of tests show the dependence of grinding scales on the parameters used machining and thickness of the sliced layer and this means the heat effects in the cutting zone.
