Split type diamond grinding wheel and manufacturing technology thereof

Abstract

The invention discloses a split type diamond grinding wheel which comprises a grinding ring tightly clamped between a pressing plate and a base plate. The grinding ring is composed of a plurality of singe teeth in a splicing mode, an anti-flying mechanism which limits the radial direction, the axial direction and the circumferential degree of freedom of each single tooth is arranged between each single tooth and the pressing plate and the base plate. Each anti-flying mechanism comprises a clamping embedded structure which is formed by matching of a convex strip and a concave groove and an embedded body with moderate hardness and deformation, the convex strips and the concave grooves are placed between the single teeth and the pressing plate or / and the base plate, the embedded bodies are arranged between the splicing grinding ring and the clamping face of the pressing plate or the clamping face of the base plate or between the clamping face of the pressing plate and the clamping face of the base plate in squeezed and deformed modes. A manufacturing technology of the diamond grinding wheel comprises the steps that all the single teeth with equiform abrasion structures are manufactured first, then all the single teeth are spliced into the grinding ring, at last the spliced grinding ring is tightly clamped between the pressing plate and the base plate, and the anti-flying mechanisms are arranged to limit the radial direction, the axial direction and the circumferential degree of freedom of each single tooth. According to the split type diamond grinding wheel and the manufacturing technology thereof, the equiform abrasion structures which are difficult to machine on the entire grinding ring are machined conveniently by being split into single teeth to be spliced.

Description

(1) Technical field: [0001] The invention relates to a metal bonded diamond grinding tool, in particular to a split diamond grinding wheel and a manufacturing process thereof. (2) Background technology: [0002] At present, the metal bond diamond grinding wheel generally adopts the powder metallurgy sintering process to manufacture the diamond working ring. The first method is often used: directly sintering the diamond working ring to the substrate. Method 2: Consolidate the sintered diamond working ring on the substrate by mechanical or gluing. Method 3: For some special-shaped wheels with intermittent teeth, brazing is usually used to weld and consolidate the diamond teeth to the steel matrix. [0003] In order to improve the efficiency level of the diamond grinding wheel and the surface finish of the processed material, it is necessary to improve the chip removal and cooling capacity of the diamond grinding wheel during the working process. The effective way is to use t...
