Abstract

The utility model relates to a diamond millstone comprising a knife head 1 and a basal body 2. Wherein the knife head 1 is thermal sintering molded of metal powders and diamond particles after being evenly mixed, the basal body 2 is directly molded on the knife head 1 through a casting pattern; the knife head 1 is circular, a parabolic lug boss 1a is arranged on one surface of the knife head, and a swallowtailed lug boss 1b embedded and fixed with the basal body 2 is arranged on the other surface, a swallowtailed slot 2b embedded and fixed with the swallowtailed lug boss of the knife head 1; and a screw thread 2a is arranged on the basal body 2. The beneficial effects of the utility model is that deficiencies such as instable wielded quality of the existing knife head and the basal body, caducous knife head, the millstone of short service life, long production period and low productivity effect are solved; and a diamond millstone which is firm and durable, sharp and has long service life, with simple processing technique, short production period and high productivity effect is provided. The utility model is applicable to abrasive machining of hard brittle materials such as the granite, the marble, the waterstone and various rostones.

Description

Diamond disk

Technical field

The utility model relates to a kind of diamond disk, and particularly a kind of aluminium base sintered type diamond disk can be widely used in the grinding of crisp hard material.

Background technology

In the prior art, its mill of the grinding-polishing of crisp hard material mostly uses 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 drop 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 grinding tool process can reduce adamantine anti-wear performance, it is poor to the purchase capabilities of diamond abrasive grain simultaneously to make binding agent with resin, plated metal, and it is relatively poor to have the heat radiation of ring-type or labyrinth-like cooling bath on its mill steel matrix, 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 the diamond powder 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 casts directly on the cutter head through casting mould, it is characterized in that: cutter head is annular, one of them face is provided with parabola shaped boss, another face is provided with the dovetail boss with the matrix build-in, be provided with on the matrix with cutter head on the dovetail groove of dovetail boss build-in; Parabola shaped boss on first face of described cutter, the center, top is a boss, the boss both sides are the boss step, parabola shaped boss quantity is 3-50, another face of cutter head is provided with the dovetail boss of annular, stop column on uniform counterbore in dovetail boss center and the matrix is joined work, and counterbore quantity is 3-30; Be annular cutter head pedestal on face of described matrix, annular cutter head pedestal is provided with the annular dovetail groove, the stop column of the uniform projection in dovetail groove center, and the counterbore at stop column and dovetail boss center is joined work, stop column quantity is 3-30, and matrix is provided with screw thread.

Deficiency and defectives such as 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, the production cycle is long, and production efficiency is low; Provide a kind of sturdy and durable, the sharp life-span is long, constant product quality, and processing technology is simple, and the manufacturing cycle is short, and the diamond disk that production efficiency is high can be used for the grinding as crisp and hard materials such as granite, marble, terrazzo, artificial stones,
