How to indentify the grinding disc materials? Different from cutting discs, most of the grinding discs use zirconium corundum. From the back side, its particles are larger and the touch is rougher, which is more suitable for grinding metal or stainless steel.
Resin grinding wheel is a grinding wheel made of resin, such as phenolic, epoxy, polyurethane, polyvinyl alcohol, etc.; resin grinding wheel has high strength, and can add reinforcing fiber mesh and steel bars to the grinding wheel, such as cutting discs, grinding discs, most of our The resin grinding wheel is not waterproof and cannot be ground with grinding fluid. Of course, there are also some resin grinding wheels that need to be ground with grinding fluid, such as epoxy resin. The grinding smoothness of the resin grinding wheel is good, and the workpiece is not easy to burn. The resin grinding wheel is used in cutting Disc, double face, heavy duty grinding wheel, polishing wheel, etc., the strength of resin bond grinding wheel is lower than that of metal bond and vitrified bond.
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.
There are many types of cutting discs on the market, and the performance requirements of the cutting discs are different in different occasions, so the choice should be based on the occasion of use and the material to be cut, which can increase the coefficient, improve work efficiency, and reduce our cost of use. Whether you are cutting metals or non-metals will also have different requirements for cutting blades. For metals such as round tubes, stainless steel, square tubes, etc., resin cutting sheets are required. Today, the editor of Damon Grinding Wheel wants to share with you how to store the cutting disc? The cutting sheet is stored in the warehouse for 2-3 years, can it still be used?
, When handling the cutting piece, it must be handled with care to prevent collision and cracking, otherwise there will be flying pieces in the process of use!
2. The cutting piece should be protected from freezing and deformation when it is stored. Moisture is the main reason for the filming of the cutting piece.
3. The cutting blade should be flat mounted on the wooden pallet or wooden frame, and the stacking height is generally not more than 1.5 meters! The higher the stack is, the more unstable the center of gravity is to prevent it from being knocked off and collapsing.
4. The storage time of the resin cutting sheet is one year. If the time is exceeded, the rotation inspection should be carried out again, and it can be used after confirming that it is qualified!
Among the commonly used cutting tools, grinding discs, cutting discs and grinding discs are the most used, and their functions and shapes are very similar. Many people think that a grinding wheel and a cutting wheel are one product, but they are not; the grinding wheel can be cut, ground, polished, and has different shapes; the cutting wheel is only used for cutting.
Grinding wheel is an abrasive tool used for grinding. During the manufacturing process, it is formed by adding a binder, compacting, and firing into the abrasive. The selection rule of the grinding wheel is that when the object to be used is hard, the density of the grinding wheel is looser or the softer one can be selected. When using materials with softer objects, you can choose a relatively denser or harder grinding wheel.
Resin cutting discs are mainly made of binder resin and abrasives. They have high impact resistance, bending strength and other characteristics. They can cut those hard metal materials, and the cutting efficiency and precision are relatively high;
The grinding disc is a thin sheet used for grinding and polishing the surface of the workpiece. The surface of the grinding disc is made of fine alumina and silicon carbide particles. The grinding disc is rotated at a high speed to make these particles to polish the workpiece. In order to achieve the ideal grinding effect, the abrasive particles of the grinding disc will be evenly distributed, and there are particle numbers of different sizes, from tens of meshes to thousands of meshes.
1. Introduction of cutting blade of angle grinder
An angle grinder, also known as a grinder or disc grinder, is a tool used for cutting steel or grinding. The angle grinder can cut hard objects such as stainless steel and steel at high speed.
Because the speed of the angle grinder is very fast, it can often reach tens of thousands. If it is used improperly, it is very easy to cause dangerous accidents. It is necessary to wear relevant protective equipment during use to avoid dangerous accidents.
Before use, check whether the cutting blade of the angle grinder can operate normally. Before use, it must be idling for a few laps to observe whether there is any abnormality. After confirming that there is no problem, you can use it with confidence.
Second, the commonly used size of angle grinder cutting blade
The commonly used sizes of angle grinder cutting blades are divided into 4 categories: 100mm (4 inches), 125mm (5 inches), 150mm (6 inches), 180mm (7 inches) and 230mm (9 inches). Some small-sized angle grinders are used in Europe and the United States.
The original intention of the angle grinder is to grind, and the cutting function is not the original intention of the design. Therefore, before use, choose high-quality cutting blades, keep both hands operating, and take relevant protective measures. When the angle grinder is running at high speed, do not pressurize the cutting blade with force, otherwise, once it is stuck, the cutting blade will be broken and splashed, or the angle grinder will be out of control. Light damage to items, serious injury!
