Problems solved by technology

However, due to the particularity of the electroplating process, it is not easy to achieve multi-layer electroplating; as the reaction progresses, it is affected by changes in the pH value of the plating solution and the current density, which increases the difficulty of the multi-layer plating process.
Moreover, in the process of use, the abrasive grains in the coating of the electroplated diamond grinding disc with multi-layer coating are difficult to ensure continuous cutting edge, which will cause the electroplated diamond g...

[0032] see Figure 1-Figure 6 , a grinding disc used for processing crystals, including a diamond cutter head 1 arranged on a substrate 3, the substrate 3 is an aluminum substrate, and more than one assembly groove 3.1 is arranged on the substrate 3, and the diamond cutter head is connected to the substrate through a bonding layer 2 catch. The diamond cutter heads 1 are distributed in strips, and chip removal grooves 1.1 are arranged between adjacent diamond cutter heads 1 . The assembly groove 3.1 is arranged on the base body 3 in a ring shape; or the assembly groove is arranged on the base body in a spoke shape.

[0033] The material components of the diamond segment 1 include iron-copper pre-alloyed powder, copper-tin pre-alloyed powder and diamond. The material components of the diamond cutter head 1 are calculated by weight percentage, the iron-copper pre-alloy powder is 10-50%, and the copper-tin pre-alloy powder is 50-90%. When the iron-copper pre-alloy powder and the...

[0047] When making a millstone, the following steps are involved:

[0048] In the first step, first weigh 35 grams of iron-copper pre-alloy powder and 65 grams of copper-tin pre-alloy powder, and mix them uniformly to obtain a mixture; then weigh 3 grams of diamond, put the diamond into the mixture, and mix uniformly to obtain a mixture material, then add paraffin oil to the mixture, and finally mix evenly in a three-dimensional mixer to obtain the material to be used, wherein the paraffin oil is 0.2-0.4% of the total weight of the mixture.

[0049] In this embodiment, the weight ratio of iron and copper in the iron-copper pre-alloyed powder is 3:2, and the weight ratio of copper and tin in the copper-tin pre-alloyed powder is 17:3. The weight ratio of isopropanol, acetone and GB600 is 30:5:1. See the first embodiment for the rest of the undescribed parts, and will not repeat them here.

[0051] When making a millstone, the following steps are involved:

[0052] In the first step, first weigh 10 grams of iron-copper pre-alloy powder and 90 grams of copper-tin pre-alloy powder, and mix them uniformly to obtain a mixture; then weigh 3.5 grams of diamond, put the diamond into the mixture, and mix uniformly to obtain a mixture material, then add paraffin oil to the mixture, and finally mix evenly in a three-dimensional mixer to obtain the material to be used, wherein the paraffin oil is 0.2-0.4% of the total weight of the mixture.

[0053] In this embodiment, the weight ratio of iron and copper in the iron-copper pre-alloyed powder is 3:1, and the weight ratio of copper and tin in the copper-tin pre-alloyed powder is 9:1. The weight ratio of isopropanol, acetone and GB600 is 30:5:1. See the first embodiment for the rest of the undescribed parts, and will not repeat them here.

Abstract

The invention discloses a millstone for processing a crystal and a manufacturing method thereof. The millstone for processing the crystal comprises a diamond tool bit arranged on a base body; the base body is an aluminum base body; one or more assembling grooves are formed on the base body; and the diamond tool bit is connected with the base body through a bonding layer. The material of the diamond tool bit comprises components of iron and copper pre-alloyed powder, copper and tin pre-alloyed powder and diamond. The material of the diamond tool bit comprises the following components in percent by weight: 10 to 50 percent of iron and copper pre-alloyed powder and 50 to 90 percent of copper and tin pre-alloyed powder, and when the iron and copper pre-alloyed powder and the copper and tin pre-alloyed powder are mixed into a mixture, the diamond accounting for 2.5 to 3.5 percent of the total weight of the mixture is added into the mixture. The millstone for processing the crystal is mainly used for replacing a conventional electroplated diamond millstone for processing the crystal, and has the characteristics of simple and reasonable structure, longer service life than the electroplated diamond millstone, high sharpness, simple connection of the diamond tool bit, low manufacturing cost, and high production efficiency.

Description

technical field [0001] The invention relates to a grinding disc, in particular to a grinding disc for processing crystal and a manufacturing method thereof. Background technique [0002] At present, the grinding disc for processing crystal usually adopts electroplated diamond grinding disc. The electroplated diamond grinding disc uses metal as the binder and diamond as the abrasive grain. The metal and diamond particles are co-deposited on the surface of the grinding disc substrate by electroplating. For example, Chinese Patent Document No. CN 1895849A disclosed a kind of electroplated diamond grinding disc on January 17, 2007, which has a disc steel substrate, and its center has a shaft hole that can be connected with the jewel machine body or other mechanical assembly. There is an electroplated diamond abrasive layer on the top, and two kinds of diamond abrasive layers with different particle sizes are plated on the steel plate substrate of the grinding disc. One diamond a...
