Abstract
The utility model relates to the field of alloy grinding tools, in particular to a diamond grinding wheel. The design key points of the diamond grinding wheel are as follows: the diamond grinding wheel comprises a diamond layer and a grinding wheel matrix, and is characterized in that a dovetail groove is arranged on the grinding wheel matrix, and the diamond layer and the grinding wheel matrix are linked through the dovetail groove and bonded through a bonding agent. The diamond layer comprises diamonds, the bonding agent and filling material, wherein the diamond is selected from No.100-No.120, the bonding agent is selected from polyimide resin, and the filling material is selected from No.200 copper powder, zinc oxide and dichromium trioxide. The material of the grinding wheel matrix is selected from ZAl501, the grinding wheel matrix is in the shape of a bowl, and the dovetail groove is arranged on the surface on the upper edge. The diamond grinding wheel can solve the problem that the diamond layer is easy to fall off, and simultaneously provides the high-quality diamond layer; furthermore, the grinding efficiency and the service life of the diamond grinding wheel using a resin bonding agent are improved.
Description
Technical field
The utility model relates to alloy grinding tool field, is specifically related to a kind of diamond-impregnated wheel.
Background technology
Diamond-impregnated wheel is mainly used in the processing rigid alloy.With respect to other grinding tools following advantage is arranged: (1) grinding efficiency is than common grinding tool height; (2) the very high capacity of heat transmission is arranged, thermal conductivity is about 9～10 times of silicon carbide abrasive particles; (3) has less radius of corner, than being easier to cut machined material.
Diamond-impregnated wheel generally is divided into three kinds: i.e. resinoid bond diamond-impregnated wheel, metal-bonded diamond emery wheel and ceramic bond diamond emery wheel.Wherein two kinds of emery wheels of resinoid bond diamond-impregnated wheel and other are compared, and have that grinding heat is little, self-sharpening good and characteristics such as grinding efficiency height, therefore are applied in widely in the grinding of hard brittle materials such as carbide alloy, pottery and glass.
The resinoid bond diamond-impregnated wheel generally is made up of three parts: abrasive wheel substrate, non-diamond layer and diamond layer.The effect of abrasive wheel substrate is to bear, and supports diamond layer; The non-diamond layer connects abrasive wheel substrate and diamond layer; Diamond layer is the working portion of diamond-impregnated wheel, also is to guarantee the diamond-impregnated wheel grinding efficiency and the key stratum in grinding life-span.If connection is bad between this three, in the emery wheel course of work, each several part just comes off easily, often occurs between diamond layer and the non-diamond layer and come off.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art, design a kind of diamond-impregnated wheel, when the solution diamond layer comes off problem easily, a kind of gem grade diamond layer is provided, improve the grinding efficiency and the service life of resinoid bond diamond-impregnated wheel.
The technical scheme that realizes the utility model purpose is:
Abrasive wheel substrate by a diamond layer and a bowl type structure is formed, and main points are that abrasive wheel substrate wall upper surface is provided with rectangle filling mouth and annular dovetail slot, and the bottom surface is provided with a pilot hole;
It is 5mm that described rectangle is filled mouth long, and wide is 4mm, the wide 2mm of annular dovetail slot, dark 1mm, the dovetail angle is 20 °, diamond layer be filled into that rectangle on the abrasive wheel substrate is filled mouthful and annular dovetail slot in and bond the material selection ZAl501 of abrasive wheel substrate by binding agent;
Described binding agent is selected the polyimide resin powder for use;
Described diamond layer is made up of diamond, bond and filler, and wherein diamond is selected 100#～120# for use, and bond is selected polyimide resin for use, and filler is made up of 200# copper powder, zinc oxide and chrome green.
Compared with prior art, characteristics of the present utility model and beneficial effect thereof are:
(1) the utility model makes abrasive wheel substrate and diamond layer rely on the dovetail groove on the abrasive wheel substrate to be linked together, and has avoided coming off between non-diamond layer and the diamond layer;
(2) diamond layer of the utility model design improves resinoid bond emery wheel grinding efficiency, prolongs 10～30% service life.
