Abstract

The invention relates to the manufacture of an abrasive tool and can be used to process various materials, in particular glass products. The purpose of the image. retention is to ensure uniform wear of the diamond layer of the circle, increase its service life, maintaining the specified profile of the circle for the entire period of its operation. To preserve the specified profile of the circle, it is necessary that the thickness of the diamond layer is variable, the circle in any area across its width relative to the section level along the axis of symmetry of the circle varies according to the law expressed by the ratio / l- (), where МС1КС S is the thickness of the diamond layer in a given transverse section; S is the maximum thickness of the diamond layer in the cross section of the circle along the axis of symmetry; R is the radius of curvature of the profile in the cross section of the circle; h is the distance from the plane of symmetry of the circle to the plane of a given cross section. 3 il.

Description

one

The invention relates to the manufacture of an abrasive tool.

The purpose of the invention is to ensure uniform wear of the profile tool.

FIG. 1 depicts a fine grinding scheme; in fig. 2 - the profile of the cavity obtained by the abrasive wheel; in fig. 3 - profile worn circle.

The abrasive wheel has an abrasive (diamond-bearing) layer 1 located on the housing 2. With this circle, a hollow is formed in the solid material 3, while different points of the surface of the diamond-bearing layer of the circle pass different paths in the material being processed. In order to ensure even wear of the circle layer, the condition of
