no. 1 example

[0029] The first step is to weigh 20 grams of iron-silicon pre-alloyed powder, 40 grams of iron-copper pre-alloyed powder, 15 grams of nickel powder, and 25 grams of copper-tin pre-alloyed powder to prepare a mixture; then weigh 4.5 grams of diamond , the particle size of diamond is 70 / 80. Put diamonds into the mixture to make a mixture, then add liquid paraffin to the mixture, and finally mix evenly in a three-dimensional mixer to prepare the material to be used, wherein the amount of liquid paraffin is 0.2% of the total weight of the mixture. ~0.4%.

[0030] The second step is granulation, adding a granulating agent to the above-mentioned ready-to-use material mixed with diamonds, and then making granules with a particle diameter of 0.4 mm to 1.2 mm. The material components of the granulation agent include isopropanol, acetone and granulation forming agent GB600. Wherein, the weight percent of isopropanol, acetone and granulation forming agent GB600 is 25-40:3-7:0.5-1.5. ...

no. 2 example

[0036] The first step is to weigh 15 grams of iron-silicon pre-alloyed powder, 42 grams of iron-copper pre-alloyed powder, 8 grams of nickel powder, and 35 grams of copper-tin pre-alloyed powder to prepare a mixture; then weigh 4.2 grams of diamond , the diamond particle size is 100 / 120. Put diamonds into the mixture to make a mixture, then add liquid paraffin to the mixture, and finally mix evenly in a three-dimensional mixer to prepare the material to be used, wherein the amount of liquid paraffin is 0.2% of the total weight of the mixture. ~0.4%.

[0037] See the first embodiment for the rest of the undescribed parts, and will not repeat them here.

Abstract

The invention relates to a diamond rubbing block which comprises a tool bit arranged on a clamping seat, wherein the tool bit comprises the following raw materials in percent by weight: 10-25 percent of iron-silicate pre-alloyed powder, 30-50 percent of iron-copper pre-alloyed powder, 10-40 percent of copper-tin pre-alloyed powder, 1-15 percent of nickel powder and the balance of diamond. The diamond rubbing block is fabricated by the steps of: mixing the iron-silicate pre-alloyed powder, the iron-copper pre-alloyed powder, the copper-tin pre-alloyed powder and the nickel powder into a mixture, and based on the total weight of the mixture, charging 3.5-5.5 wt% of the diamond into the mixture. The weight ratio of iron and silicate in the iron-silicate pre-alloyed powder is 8-9:1, the weight ratio of iron and copper in the iron-copper pre-alloyed powder is 2-3:1, and the weight ratio of copper and tin in the iron-tin pre-alloyed powder is 4-6:1. The invention has the characteristics of simple and reasonable structure, short sintering time, high production efficiency, long service life, good quality stability and wide application range.

Description

technical field [0001] The invention relates to a diamond grinding block and a manufacturing method thereof. Background technique [0002] Chinese Patent Document No. CN 101407045A disclosed a diamond grinding block and its preparation method on April 15, 2009. It is characterized in that: the preparation process is: a. material selection, the matrix powder is selected from Fe-Cu-Sn ultra-fine pre-alloyed Powder, the Fisherman's particle size is 2-5μm, and the composition is as follows in terms of mass percentage: 30%-60% Fe content; 30%-40% Cu content, 10%-30% tin content; use type I material, II The low-grade diamond used as the molding material or a mixture of the two, according to the coarse grinding or fine grinding grade of the grinding block, the diamond particle size is 100 mesh to 500 mesh; b. Mixing, mix the matrix powder and diamond in proportion with a mixer, Diamond accounts for 2.5%-4.5% of the mass of the mixture; c.. Gel injection molding, first configure th...
