At the same time, resin-bonded grinding wheels are a tool that is in greater demand. It is a tool made by gluing diamond or cubic boron nitride (CBN) abrasives and inorganic fillers using benzoic acid and polyamide or other resins as binders. This tool is being effectively used in various grinding operations, such as surface grinding, centerless grinding, slotting, and internal grinding. It is an ideal grinding tool for super heat resistant stainless steel, cermet, ceramic products, glass products, limonite, high speed steel, alloy tools and many other new superhard materials.
There are many kinds of special resin bonded diamond grinding wheels for rapid cold cutting. These grinding wheels are particularly suitable for grinding carbide tools (such as saws, cutting machines, drilling tools, end mills, etc.). In addition, these tools can also be used for precision grinding of cemented carbide molds, rollers and carbide wear parts. Resin bonded grinding wheels are the first choice for precision machining of ceramic products and for grinding tungsten carbide and thermal spray coatings on ceramic products. Resin bonded grinding wheels can also be used in combination with CBN to grind high-speed steel, tool and die steel, and super heat-resistant alloys above FtRC50.
In the production process, emery wheels are used to polish the belt. Generally, the grinding wheel should be removed and cleaned after 5-7 days of operation. (There are polished rubber crumbs on it, which adhere tightly to the surface of the emery after high temperature friction, and it is difficult to clean) Now we soak in acetone for 2 hours and then clean it with imported detergent. The effect is very good, but it is not environmentally friendly and energy-saving . Cleaning requirements: 1. To be environmentally friendly, free of ketones and not halogenated hydrocarbons. 2. Don’t damage the diamond wheel
The grinding wheel must be carefully inspected and identified before installation. The steps of inspection and identification are: 1. Check whether the grade of the grinding wheel is correct and whether it meets the performance, shape and size of all selected grinding wheels. 2. Check and identify the appearance and structure of the grinding wheel. Use your eyes to observe whether the appearance of the grinding wheel is damaged (or cracked). Grinding wheels with appearance damage (or cracks) cannot be used. In addition, both ends of the grinding wheel are required to be flat without any obvious skew. 3. Check and identify the internal cracks of the grinding wheel. Hold the grinding wheel in your hand and tap the grinding wheel with a wooden hammer to listen to the sound. The grinding wheel without cracks emits a crisp sound, and the grinding wheel with cracks has a hoarse sound, which cannot be used.

There are many kinds of grinding wheel products on the market now, and different types of grinding wheels have different scopes of use. Resin grinding wheel has irreplaceable grinding effect in industrial production. The high-quality resin grinding wheel has better use effect and longer life. The quality is determined by the raw materials for making the resin grinding wheel. The following Damon grinding wheel editor will share with you the three major raw materials of the resin grinding wheel!
1. Liquid phenolic resin. The fluctuation range of indicators such as solid content, viscosity, gel time and water solubility all have different degrees of influence.
2. The stability of mesh technical indicators. The glue content of the mesh has an impact on the strength, viscosity and cutting performance of the resin wheel. Therefore, we must continuously improve the performance, mainly in the fluctuation of the strength of the grinding wheel, the deformation of the slice, and the layering of the grinding disc. Theoretically speaking, under the condition that the grinding wheel manufacturing process is stable and allowed, the higher the glue content of the mesh, the higher the strength of the grinding wheel, the better the bonding performance, and the more stable cutting and grinding.
3. Powder phenolic resin. The process of powder phenolic resin is an important performance index that affects the structure of the binder. The particle size affects the amount of wetting agent, and the content of volatile matter is also very important. In the actual grinding wheel production process, it is necessary to ensure the stability of the performance of each batch of powder resin, so as to ensure the quality of the grinding wheel.
Angle grinders, also known as grinders or disc grinders, can be used to grind molds. Many molds need to be polished at the end of production, so as to ensure the smoothness of the mold, and the products produced by using the mold can be equally smooth without fine lines. Therefore, in the daily grinding and grinding work, the grinding disc has become the most commonly used and most easily worn accessories of the grinding machine. In addition to producing angle grinding discs, Damon grinding wheel also produces grinding discs, cutting discs, louvers, etc. The following editor will share with you the scope of application of angle grinding discs:
Angle grinders are tools for grinding, lapping and polishing. Most of the abrasives are artificial abrasives made of abrasives and binders, and there are also natural abrasives that are directly processed from natural ore rocks. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasive tools are also used in food processing, paper industry and processing of non-metallic materials such as ceramics, glass, stone, plastic, rubber, and wood.
In the process of mold manufacturing, polishing is a very important process, so the quality of abrasives directly affects the life and quality of the mold, so the mold industry is very important to the quality of abrasives. After mastering the grinding of abrasives The working principle and process of polishing, and then select the appropriate abrasives according to the requirements of the mold itself, and carry out correct grinding and polishing, that is, to prolong the service life and production quality of the mold. The quality of the mold is high, and the quality of the product can also be improved. These series are complementary to each other.
Grinding wheel is an important cutting and grinding tool. Its appearance has brought great convenience to our production and processing. The most commonly used abrasives for grinding wheel customization are brown corundum and white corundum, followed by black silicon carbide and green silicon carbide, and the rest are commonly used. There are also chrome corundum, single crystal corundum, microcrystalline corundum, zirconium corundum. Due to the different abrasives in the grinding wheel and the different manufacturing processes, the final produced grinding wheel is also very different, which will also affect the cutting quality and processing efficiency of the grinding wheel. The following Damon grinding wheel editor will share with you the difference in the quality of the grinding wheel:
(1) Abrasive particle size: The common particle size is: 22#-80#, and the cutting efficiency is low when the particle size is fine.
(2) Grinding wheel hardness: commonly used hardness: P, Q, R; N, S; generally use a harder grinding wheel to reduce grinding wheel wear. Its hardness is controlled by factors such as the amount of binder, molding density, firing temperature and firing time.
(3) Binder: Commonly used resin binders are: powdered phenolic resin, liquid phenolic resin. Powdered phenolic resin has good craftsmanship, the molding density of the abrasive tool is slightly smaller, the texture number is slightly larger, and the price is higher than that of the liquid phenolic resin; the price of the liquid phenolic resin is low, but the material is easy to agglomerate and the mixing material is not easy to be evenly distributed, which is easy to cause localized abrasives. hard.
(4) Organization: The organization number of the cutting wheel should be slightly larger to improve the cutting efficiency: if it is too large, it will affect the strength. The commonly used organization numbers are 3 to 7.

The cutting discs are all made of high-strength resins and specially-made abrasives, and can be cut in a variety of materials, such as stainless steel, titanium alloys, ordinary steel, viscous metals, high carbon steel, non-metals, etc. Exquisite craftsmanship guarantees high cutting efficiency and the best economic results for workpieces of different materials. Today, the editor of Damon grinding wheel will share with you the precautions for the installation and use of cutting discs:
1. When the cutting disc is installed on the angle grinder, the flange surface in contact with the cutting disc is required to be clean and flat. When tightening the cutting disc, the tightness is required to be moderate. Only special wrenches are allowed to reinforce, and supplementary fixtures (such as extended wrenches, etc.) are prohibited. To prevent man-made damage to abrasives!
2. The use speed of the cutting blade cannot exceed the working line speed specified by the cutting blade trademark. When using a pneumatic grinder, it is necessary to prevent the air pressure from being unstable, causing the cutting blade to exceed the maximum speed!
3. When using the cutting blade, the force should be applied slowly. If the force is too strong, the phenomenon of stalling, jamming and breaking of the cutting blade may occur.
4. The cutting piece is only allowed to be installed and used in a single piece, and it is strictly forbidden to install and use two or more pieces at the same time!
5. Resin cutting discs are only allowed to be used for cutting, not for grinding!
6. The equipment used for cutting discs should comply with the provisions of GB4674 grinding machinery safety regulations!
The cutting blade wears less, has a long service life, and has a high grinding ratio. Under the conditions of reasonable use, good economic effects can be obtained, especially for materials that are difficult to process with ordinary abrasives, the economic effect is better.
