Description

(54) SIDE GRINDING CIRCLE

one

The invention relates to the manufacture of diamond abrasive tools.

Known mechanical grinding tool, made in the form attached to the body of several abrasive layers, fastened to each other non-abrasive layer.

To put each subsequent layer into operation after the previous one has worn out, it is necessary to remove the intermediate non-diamond bonding layer, which complicates the grinding process 1.

The purpose of the invention is to create an end abrasive tool with a sufficiently thick diamond layer, without the need to introduce an additional operation to remove the intermediate layer.

This goal is achieved by the fact that the grinding face tool is made with 1 ~ a few diamond layers having a tapered cross section fixed to the wheel body using glue, for example, a VC brand, or by other means. The half angle of the cone a / 2 is 68-87 °.

With a width (5-20 mm) and a height of the diamond layer (mm) with the resulting maximum gap between the layers up to 0.1 mm

The width of a brilliant-colored (for example, glue) ribbon is 0.25-1.9 mm and practically does not affect the work of the circle. The half angle of the cone, equal to 68-87 °, is adopted from the conditions of optimal circle operation: a decrease in the angle of the cone (a / 2 68 °) will lead to a decrease in the width of the diamond layer, which goes beyond the limits recommended by the guests, and uv; 2 87) - to an excessively large width of the non-diamond layer, as a result of which the circle may lose its burning ability and form defects on the products being processed.

FIG. 1 shows the diamond wheel, a general view; in fig. 2 - section A-A-in FIG. one.

The circle consists of body 1 and diamond rings 2, 3, and 4 and adhesive bonding 5. The upper ring 2 has a flat upper working surface and a sloping bottom; inner ring 3 has both beveled 20 surfaces; the lower ring 4 has a beveled upper surface and a flat, lower one. The body of the circle 1 is shaped according to GOST. The connection of diamond rings can be adhesive 5, for example, KK VK glue, mechanical or some other .. In connection with the complexity and laboriousness of processing products from highly hard materials (diamond smoothers, carbide modular milling cutters and others), as well as the scarcity of the material of the cases of circles The proposed circle design allows high-performance processing of such products and saves the material of the wheel bodies; The invention The face grinding wheel is made in the form of a body with several diamond rings arranged in layers, characterized in that, in order to improve the performance of a multi-layer tool, the rings are coupled to each other along conical surfaces.
