Embodiment 1

[0047] (1) Adopt mechanical mixing method to mix matrix powder and diamond particle for 1h to make it uniform, so as to obtain mixed powder; The volume of ~50 mesh diamond particles accounts for 50% of the total volume of the diamond particles, and the diamond concentration is 35%; the matrix powder is composed of the following components by weight percentage: pre-alloyed powder FeCuCoSnTiCr: 55%, Ni: 5%, Cu : 30%, Sn: 9%, graphite powder: 1%; the weight percentage content of each element in the pre-alloyed powder FeCuCoSnTiCr is: Fe: 69%, Cu: 10%, Co: 13%, Sn: 7% , TiCr alloy (in TiCr alloy, Ti: 50wt%, Cr: wt% 50): 1%. The FeCuCoSnTiCr pre-alloyed powder is first prepared by a conventional water atomization method, and then the above matrix powder is prepared by a conventional water atomization method.

[0048] In the hooking processing step, the hooking on the outer surface of the base is processed on the pre-substrate by using a drill to drill holes and remove the burrs. ...

Embodiment 2

[0056] Except that the component content of the carcass powder is different from that of Example 1, other steps are the same as in Example 1. The composition content of the matrix powder in this embodiment is: pre-alloyed powder FeCuCoSnTiCr: 50%, Ni: 10%, Cu: 25%, Sn: 10%, graphite powder: 5%.

[0057]The properties of the 10 floor grinding wheels obtained in this embodiment were tested, and the specific properties are shown in Table 2.

[0058] Table 2 head performance

[0059]

[0060] During the use of the 10 floor grinding wheels in this embodiment, there is no phenomenon of cutter head falling off, chips can be removed smoothly, and there is no phenomenon that the floor grinding wheels cannot be used due to the inability to remove chips. The surface of the workpiece has no burrs, no scratches, no fog and chatter marks.

Embodiment 3

[0062] Except that the component content of the carcass powder is different from that of Example 1, other steps are the same as in Example 1. The composition content of the matrix powder in this embodiment is: pre-alloyed powder FeCuCoSnTiCr: 60%, Ni: 6%, Cu: 24%, Sn: 9%, graphite powder: 1%.

[0063] The properties of the 10 floor grinding wheels obtained in this embodiment were tested, and the specific properties are shown in Table 3.

[0064] Table 3 head performance

[0065]

[0066] During the use of the 10 floor grinding wheels in this embodiment, there is no phenomenon of cutter head falling off, chips can be removed smoothly, and there is no phenomenon that the floor grinding wheels cannot be used due to the inability to remove chips. The surface of the workpiece has no burrs, no scratches, no fog and chatter marks.

Abstract

The invention discloses a terrace grinding wheel and a manufacturing method thereof. The terrace grinding wheel comprises a base body and a plurality of tool bits sintered to the outer circle surfaceof the base body. Each tool bit comprises a front part and a rear part, wherein the top end of the front part is a sharp corner, and a groove is formed in the bottom end of the rear part. The tool bits are fixed to the base body through a hot press sintering method. According to the technical scheme, rapid cutting and smooth cutting removing are achieved, and the purpose of removing a terrace coating is achieved.

Description

technical field [0001] The invention relates to the field of diamond tools, in particular to a floor grinding wheel and a manufacturing method thereof. Background technique [0002] With the development of material technology and manufacturing technology, various high-performance new materials are constantly emerging, which requires cutting tools to have high hardness, thermal stability, chemical inertness and appropriate toughness, thus bringing great challenges to traditional diamond tools . [0003] There is a strong adhesion between the floor paint and the concrete floor. Generally, the thick layer is sheared and torn off the surface layer first, while the thin layer of paint directly adhered to the concrete is removed by grinding with a coarse-grained diamond grinding wheel; When the grinding wheel removes the thin coating, due to friction and heat, the organic coating tends to soften and adhere to the diamond grinding disc segments, making the cleaning work difficult....
