preparation example Construction

[0021] The preparation method of light weight high-efficiency diamond grinding wheel of the present invention is as follows:

[0022] 1. Mixing: Weigh CuSn alloy powder, FeCoCu alloy powder, Co powder, and diamond according to the ratio and pour them into the mixer for 4 hours to ensure uniform mixing without color difference; among them, the diamond is used with a strength of 25-35 kg , a particle size of 35 / 40, and / or 45 / 50 in a concentration of 20-50%.

[0023] 2. Cutter head sintering: Select the required graphite mold and put it into the sintered iron mold frame. After the graphite mold is assembled as required, add a baffle on the outside, tighten the mold with a wrench, and mix it evenly with a balance with an accuracy of 0.1g. Weigh the metal powder according to the calculated weight and put it into the stone black mold, add the pressure head, tighten it with a wrench, put the assembled graphite mold into a hot press with a power of 80kw for sintering, keep it warm for...

Embodiment 1

[0029] This embodiment relates to a Φ125 lightweight and high-efficiency diamond grinding wheel, which is prepared by the following process:

[0030] (1) prepare mixed powder: choose metal powder by following percentage by weight: CuSn alloy powder 35wt%, FeCoCu alloy powder 40wt%, Co powder 25wt%; Diamond strength 30 kilograms, particle size is 35 / 40, and concentration is 25%, proportioning Then pour it into the mixer and mix it for 4 hours;

[0031] (2) Cutter head sintering: select the cutter head graphite mold, put it into the iron sintering mold frame after assembly, add graphite baffle on the outside, tighten it with a wrench, weigh 21.8 grams of mixed powder with a balance with an accuracy of 0.1 grams, and pour it into In the graphite mold, tighten the mold with a wrench after adding the graphite indenter, put the assembled graphite mold into a hot pressing sintering machine with a power of 80KW, heat to 800°C, and press 250Kg / cm 2 , keep warm for 3 minutes, cool down...

Embodiment 2

[0035] This embodiment relates to a Φ115 lightweight and high-efficiency diamond grinding wheel, which is prepared by the following process:

[0036] (1) prepare mixed powder: choose metal powder by following percentage by weight: CuSn alloy powder 40wt%, FeCoCu alloy powder 45wt%, Co powder 15wt%; Diamond strength 35 kilograms, particle size is 35 / 40, and concentration is 25%, proportioning Then pour it into the mixer and mix it for 4 hours;

[0037] (2) Cutter head sintering: select the cutter head graphite mold, put it into the iron sintering mold frame after assembly, add graphite baffle on the outside, tighten it with a wrench, weigh 21.5 grams of mixed powder with a balance with an accuracy of 0.1 grams, and pour it into In the graphite mold, tighten the mold with a wrench after adding the graphite indenter, put the assembled graphite mold into a hot pressing sintering machine with a power of 80KW, heat to 780°C, and press 250Kg / cm 2 , keep warm for 3 minutes, cool down...

Abstract

The invention relates to a light and efficient diamond grinding wheel, and belongs to the technical field of diamond cutting tools. The light and efficient diamond grinding wheel comprises an aluminum substrate and diamond tool bits. Outwards-extending protruding parts are arranged on the bottom edges of the diamond tool bits. The aluminum substrate comprises a grinding installation face. The diamond tool bits are arranged on the grinding installation face. The extending protruding parts are embedded in the grinding installation face. The light and efficient diamond grinding wheel is formed by high-strength alloy aluminum at a time, the bottoms of the diamond tool bits are embedded in the alloy aluminum, it is ensured that the tool bits do not fall in the use process, and therefore many subsequent procedures are reduced, silver solder is saved, the manufacturing cost is effectively reduced, the service life of the diamond grinding wheel is ensured as well, and the light and efficient diamond grinding wheel is particularly suitable for stone processing and concrete road face grinding.

Description

technical field [0001] The invention relates to the technical field of diamond cutting tools, more specifically, the invention relates to a light-weight and high-efficiency diamond grinding wheel. Background technique [0002] Diamond is the hardest material among known materials, so diamond cutting tools have become an indispensable material for processing various hard materials. Diamond cutting tools are made by mixing metal powder and artificial diamond particles, pressing and sintering. Moreover, with the continuous development of society, the scale of infrastructure construction continues to expand, which also provides a broader application market for diamond tools. With the acceleration of urbanization, the scale of infrastructure construction continues to expand, and the development and construction of housing and roads provide a broad market for diamond tool applications. Diamond tools have played a vital role in road cutting, stone processing, ceramics, polysilico...
