Abstract

The utility model relates to a diamond grinding disc which comprises a knife head 1 and a base 2; wherein, the knife head 1 is formed from diamond particles and metal powder evenly mixed through hot pressing and sintering; the base 2 and the knife head 1 are welded together; the knife head 1 is circular; an arc or straight lug boss 1a is arranged on one of the planes of the knife head 1; a lug boss 2b embedded and fixed with the internal circular arc of the knife head 1 is arranged on the base 2; a screw 2a connected with en electric tool is arranged on the base 2; a circular hole 2c for chip discharging and weight reducing is arranged on the base 2; a flat 2d to fix the grinding disc is arranged on the base 2 and the diameter of the base is smaller than the diameter of the knife head. The utility model solves the shortcomings that the welding of the existing knife head and the base is not stable in welding quality; the knife head is easy to fall off; the grinding disc is short in service life, long in producing period, and low in producing efficiency and the chips are not easy to discharge, and provides the diamond grinding disc with firmness, stability, sharpness, long service life, stable quality, simple producing technology, short producing manufacturing period and high producing efficiency, and can be used for the grinding processing of brittle and hard materials like granite, marble and terrazzo as well as various kinds of artificial stones.

Description

Single face turbine type diamond disk

Technical field

The utility model relates to a kind of diamond disk, and particularly a kind of welded type single face turbine 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, and emery wheel is made abrasive particle with carborundum, corundum, and cement or pottery are as binding agent, cost is lower, but the adhesion between abrasive particle and the binding agent is poor,, hardness is little, abrasive particle is easy to come off during grinding, grinding performance is poor, and 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 grinding tool 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; The processing of stone that discloses number of patent application 88201202.9 on the modern utility model patent communique adopts the sulfate liquor of nickeliferous composition that diamond dust is electroplated onto on the bistrique steel body and forms with diamond grinding head, its feature is to be symmetrically distributed with two circular holes on the mill steel matrix, flexibly connect with abrasive material side's body, be used for the processing of stone industry, be convenient to change, but have shortcomings such as being not easy to the heat radiation cooling.

The utility model content

The purpose of this utility model is that the defective and the deficiency that overcome prior art provide a kind of sturdy and durable, and the sharp life-span is long, and manufacture craft is simple, 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 after Thermocompressed sintering and forming by metal dust and diamond particles, matrix welds together with cutter head after machining, it is characterized in that: cutter head is annular, and one face is provided with parabolic type or linear pattern boss 1a, and another side is the plane; Face of matrix is the annular pedestal, and the annular pedestal is provided with round ring boss 2b, and this boss cooperates with the cutter head inner arc surface, another face of matrix is provided with the connecting thread 2a with electric tool, be provided with the flat 2d that is used for fastening mill, be provided with the circular hole 2c of chip removal and loss of weight in the middle of the matrix.

The beneficial effects of the utility model are: solved existing cutter head and matrix welding quality instability, cutter head easily comes off, and abrasive disk life-span is short, production cycle is long, production efficiency is low, is difficult for deficiency and defectives such as chip removal, provides a kind of sturdy and durable, the sharp life-span is long, constant product quality, processing technology is simple, and the manufacturing cycle is short, the diamond disk that production efficiency is high can be used for the grinding as hard brittle materials such as granite, marble, terrazzo and various artificial stones.
