Problems solved by technology

[0002] Diamond materials are widely used in industry, and can be used to manufacture a variety of tools such as knives, grinding wheels, abrasive tools, etc. Due to the characteristics of diamond materials, it is difficult to combine with other materials, so it is easy to fall off from the base of the tool, resulting in the use of tools. Short lifespan and increased production costs

Embodiment 1

[0011] Embodiment 1: as shown in Figure 1, the present invention is by: a glass layer 2 is arranged on the diamond 1 surface; A cubic boron nitride layer 3 is arranged on the described glass layer 2, and a cubic boron nitride layer 3 surface layer is arranged on the described cubic boron nitride layer 3. Titanium layer 4.

Embodiment 2

[0012] Embodiment 2: Diamond 1 is granular and has an irregular and uneven surface. The glass layer 2, cubic boron nitride layer 3 and titanium layer 4 form a composite according to the irregular and uneven surface of the diamond 1. Layer, wrapping diamond 1.

Embodiment 3

[0013] Embodiment 3: A method for manufacturing a diamond surface-coated glass-coated cubic boron nitride-coated titanium-coated composite structure, the steps of which are as follows:

[0014] Step 1: Coating a layer of glass on the diamond; equipment used: ordinary resistance oven; the steps are as follows;

[0015] Step 1) Put 120g of rosin and 120ml of alcohol in the bottle to completely melt the rosin;

[0016] Step 2) Fully mix the diamond with the above solution at a ratio of 1000CTS / 60ml, then spread it out and let it dry naturally; use glass powder with a particle size 5-6 finer than diamond, for example, the coating particle size is 80 / 100 The diamond of # uses glass powder of 230 / 270~270 / 325#;

[0017] Sodium water glass: Na 20 n. SiO 2 .nH 2 O;

[0018] Step 3) Fully mix the glass powder and diamond with a ratio of 4:1 and pack into a jar;

[0019] Step 4) Preheat the oven to 110°C, put the jar in step 3) into the oven for 2 hours, take it out and cool it;

Abstract

The invention relates to a diamond surface coating glass, coating cubic boron nitride and titanizing composite structure and its manufacturing method. Diamond surface has a glass layer. The glass layer has a cubic boron nitride layer. Its surface has a titanizing layer. The main advantages of the invention are that diamond inner surface layer cubic boron nitride is inert to iron element material and surface is rough. The outer layer is coating a metallic titanium layer. It is a special abrasive grain with diamond and cubic boron nitride two abrasive material properties and rough-fine abrasive grain structural property. It is used to make resin binding-agent grinding tool to process hard alloy to reach workpiece quality special demand. The volume of the treated diamond is increasing. The abrasive grain of the grinding tool is distributed uniform, and coating glass- cubic boron nitride- titanizing. The compound coating diamond is mainly used in resin binding-agent grinding tool to realize compound grinding effect of diamond, cubic boron nitride, and rough-fine abrasive grain.

Description

technical field [0001] The invention relates to a diamond surface-coated glass-coated cubic boron nitride-coated titanium composite structure and a manufacturing method. Background technique [0002] Diamond materials are widely used in industry, and can be used to manufacture a variety of tools such as knives, grinding wheels, abrasive tools, etc. Due to the characteristics of diamond materials, it is difficult to combine with other materials, so it is easy to fall off from the base of the tool, resulting in the use of tools. The lifespan is low and the production cost increases. Utility model content [0003] The purpose of the present invention is to improve the disadvantage of difficulty in combining diamond materials with other materials in the prior art and provide a diamond surface-coated glass-coated cubic boron nitride-coated titanium-coated composite structure and a manufacturing method. [0004] To achieve the above object, the present invention adopts the foll...
