“…The basic causes of grinding wheel imbalance include the tolerance of the clamping wheel, the inhomogeneity of the wheel, the parallelism and centering of the wheel. In the case of clamping the grinding wheel on the grinding mandrel, the imbalance of the initial imbalance of the clamping mandrel and the grinding wheel / wheels is created [7][8][9]. The term unbalanced tool set means a rotating body whose central axis of inertia does not coincide with the axis of rotation [10].…”

The article examines the effect of balancing the grinding wheel set on the accuracy and roughness of the machined surface during the production of cutting tools. Screw drills with a diameter of 12 mm were manufactured as well as test specimen in the shape of a recess with a width of 20 mm and a diameter of 18 mm. The workpiece material was sintered carbide (WC+Co). Properly balanced and unbalanced sets of cubic boron nitride (CBN) and synthetic diamond grinding wheels were used in the production of the tools and test specimens. A WZS 60 Reinecker tool grinder was used as the machine. The parameters of surface roughness and dimensional accuracy were measured in the experiment. Surface roughness was evaluated on a Zeiss Surfcom 5000 shape and contour measuring machine. Dimensional accuracy measurement was performed on an optical measuring machine Zoller Genius 3. In terms of dimensional accuracy, tools and test specimen s produced by wheel balancing to a lower level of balance quality G show greater dimensional inaccuracy than tools and test specimen s produced by wheel sets that were balanced to a higher quality level of balance G. From the point of view of evaluating the surface roughness, the results were not clear, but the tools and test specimens produced by CBN grinding wheels showed better surface roughness, regardless of the quality level of balance G.

Solid cutting tools are widely applied in the machining of shape parts and mainly fabricated using the grinding operations. Solid cutting tools are of specific geometry and shape. The tool geometry is created by mutual movement grinding wheels and stock. In the grinding of its manufacturing, grinding wheels are worn out gradually with the grinding number increasing. The wearing grinding wheel has a significant influence on the accuracy geometry of the tool produced. The paper focuses on the wear of the grinding wheels based on diamonds, and the grinding wheels based on cubic boron nitride. The wear rate of the grinding wheels is affected by the properties of a grinding wheel, grinding conditions, and type of cutting material. A measure of the ability of a grinding wheel to remove material is given by the Grinding ratio. The grinding ratio (G ratio) is defined as the volume of material removed (Vw) divided by the volume of wheel wear (Vs). Periphery grinding wheels were used in the experiments. Cylindrical face grinding was used for the machining of sintered carbide stock with a diameter of 20 mm. The results of the experiment show that the diamond-based grinding wheels are more suitable for grinding sintered carbide.
