Abstract
The utility model relates to a diamond millstone, comprising a bit 1 and a basal body 2. Diamond particles and metal powders, after being mixed homogeneously, are heat pressed and sintered, forming the bit 1. The basal body 2, after being mechanically processed, is welded with the bit 1. The utility model is characterized in that: the bit 1 is fan shaped, on face of the bit is provided with a fan-shaped groove 1a, and the other face of the bit 1 is a plane and welded with an annular plane base which is arranged on one face of the basal body 2. The utility model solves the deficits and defects on the existing millstone that the welding quality of a bit and a basal is unstable, the bit is easy to abscise, the sharpness is not enough, chips are difficult to be removed, the production cycle is long, and the production efficiency is low, and provides a sharp diamond lower millstone with long service life, stable performance, short production cycle, and high production efficiency. Thus, the utility model can be used to grind and process hard and brittle materials such as granite, marble, terrazzo, and various artificial stone materials.
Description
Technical field
The utility model relates to a kind of diamond disk, and particularly a kind of welded type sector diamond disk can be widely used in the grinding of crisp hard material.
Background technology
In the prior art, the grinding-polishing instrument of crisp hard material mostly adopts emery wheel, emery wheel is made abrasive particle with carborundum, corundum, and cement or pottery are as binding agent, and cost is lower, but the adhesion between abrasive particle and the binding agent is poor, hardness is little, and abrasive particle is easy to come off during grinding, and grinding performance is poor, efficient is low, the cost height.Also usable stone is made abrasive particle in recent years, with resin, bronze, pottery, plated metal diamond disk as binding agent, wearability is good, the grinding efficiency height, but the high temperature of producing in this mold process can reduce adamantine anti-wear performance, simultaneously make the assurance ability of binding agent to diamond abrasive grain with resin, plated metal, its mill steel matrix has ring-type or the heat radiation of labyrinth-like cooling bath is relatively poor, and this mill also is not easy to the grinding corner; Disclose the processing of stone diamond disk of number of patent application 02252668.4 on the modern utility model patent communique, its feature is sturdy and durable, welding quality stable; Defectives such as but it is not enough to there is sharpness, and the manufacturing cycle is long, and production efficiency is low.
The utility model content
The purpose of this utility model is to overcome the defective and the deficiency of prior art, provides a kind of sturdy and durable, sharp, the life-span is long, manufacture craft is simple, sector diamond disk with short production cycle.
The technical solution of the utility model is: a kind of diamond disk comprises cutter head, matrix.Cutter head is mixed by metal dust and diamond particles after Thermocompressed sintering and forming, and matrix welds together with cutter head after machining.It is characterized in that: cutter head is fan-shaped, and one face is provided with scalloped recess, and another face is the plane, and the annular flat base that is provided with a face of matrix welds together, and matrix is provided with screw thread, the circular hole, flat that is connected with electric tool.
The beneficial effects of the utility model are: solved deficiency and defectives such as existing mill cutter head and matrix welding quality instability, cutter head easily come off, sharpness is not enough, chip removal is difficult, the manufacturing cycle is long, production efficiency is low, a kind of sharp, life-span length, stable performance, the manufacturing cycle is short, production efficiency is high diamond disk are provided, have can be used for grinding as hard brittle materials such as granite, marble, terrazzo and various artificial stones.
