Problems solved by technology

The disadvantage of this method is that the temperature measurement accuracy is poor during the hot pressing process, the temperature is not uniform, and the final quality is often greatly affected by the original oxidation degree of the powder, and is also related to the accuracy of the filling weight, the dimensional stability of the mold and the pressure.
Moreover, it is difficult to break the sample block, which needs to be cut into pieces, strips and then broken, so it is difficult to produce in batches

Embodiment 1

[0030] This embodiment provides a magnetic abrasive, and the specific structure diagram is shown in figure 1 and figure 2 , the magnetic abrasive is a spherical or elliptical magnetic abrasive with a core-shell structure and a particle size of about 150 meshes. It specifically includes a magnetic induction core 1 and a grinding shell bonded to the surface of the magnetic induction core 1 by sintering, wherein the grinding casing is prepared by mixing the bonding agent 2 and the abrasive particles 3 through heating, melting and cooling. Thus, the abrasive particles 3 are bonded to the magnetically sensitive core 1 by the melted and solidified binder 2 .

[0031] The magnetic material provided in this embodiment is detected by a scanning electron microscope, and the structure is as follows image 3 and Figure 4 and Figure 5As can be seen from the figure, the external shape of the magnetic abrasive is spherical or elliptical, and there are a plurality of magnetic induction...

Embodiment 2

[0042] This embodiment provides a magnetic abrasive, and the structure of the magnetic abrasive is substantially the same as that of the magnetic abrasive in Embodiment 1, except that the particle size of the magnetic abrasive provided in this embodiment is about 100 meshes. The binding agent is prepared by the following steps: Calculated in parts by mass, firstly SiO 2 18 parts, α-Al 2 O 3 30 copies, B 2 O 3 18, K 2 O 1 part, Li 2 10 parts of O, 5 parts of ZnO, 0.5 parts of MgO, La 2 O 3 1.1 copies, Y 2 O 3 0.2 part is mixed, ground and crushed, and sieved to obtain a mixed powder with a particle size of less than 200 meshes, then the mixed powder is smelted at a temperature of 1200 ° C for 1 hour, and after cooling, it is ground and crushed, and air-selected to obtain the combination with a particle size of less than 4000 meshes. agent particles.

[0043] The abrasive particles 2 are superhard materials, preferably, the superhard materials are polycrystalline ...

Abstract

The invention provides a magnetic grinding material. The magnetic grinding material comprises a magnetism sensing core, and a core housing structure of a grinding housing which wraps the magnetism sensing core, wherein the grinding housing comprises a binding agent and grinding material particles; the grinding material particles are adhered to the magnetism sensing core by hot melting the binding agent. According to the magnetic grinding material, the surface wrapping layer of the magnetism sensing core is reasonably designed, so that the grinding efficiency of the magnetic grinding material is improved, and the self-sharpening performance remains, and as a result, the consistency and stability of the grinding process can be ensured; the magnetism sensing material is used as the core of the magnetic grinding material; the magnetic grinding material is easy to recover. The invention further provides a preparation method of the magnetic grinding material. The preparation method comprises the steps of supplying the magnetism sensing core particles and the binding agent particles, and preparing and sintering semi-finished product, namely, small balls, of the magnetic grinding materials. According to the method, the grinding material particles and the magnetism sensing core particles are sintered through the high-temperature-sintered binding agent powder, so that the oxidizing degree of the magnetism sensing core particles can be effectively reduced. The preparation method is simple in processes, and industrial production is easily carried out.

Description

technical field [0001] The invention relates to the field of abrasive materials, in particular to a magnetic abrasive and a preparation method thereof. Background technique [0002] Abrasives are widely used in industry and are known as industrial teeth, especially when machining high-precision or low-roughness parts or particularly hard parts, abrasives are essential. With the rapid development and structural adjustment of my country's machinery manufacturing industry, the abrasive industry has higher and higher quality requirements for abrasives, prompting abrasive manufacturers to continuously improve their production processes. [0003] At present, the magnetic grinding technology in the grinding process is a finishing technology, because the magnetic abrasive used in the grinding process can form a magnetic brush with self-sharpening and special adaptability. Therefore, this technology is being used more and more in the production field, especially in the field of comp...
