CNDOME Grinding Wheel teaches you how to choose the right grinding wheel?
In recent years, the development of grinding wheel manufacturers has gradually slowed down with the development of environmental protection requirements. With the improvement of infrastructure and the increase of prices of key components, many companies have a certain degree of advantage in terms of production layout. Grinding wheels have also become the most important type of abrasive tools in industrial grinding.
The resin is used as the bonding agent and the glass fiber mesh is used as an enhanced high-speed grinding tool. It has high toughness and impact strength, high grinding rate, convenient and safe to use. The maximum operating speed can reach 80m/s. It is installed on a portable angle grinder for free grinding. It is easy to use and is widely used in automobiles, ships, machinery production, metallurgy and chemical construction. Clean up welds, solder joints, polish castings, burrs, burrs, repair metal surface defects, etc.
Common abrasives for grinding wheels include brown corundum (A), white corundum (wA), black corundum (BA), black silicon carbide (c), etc. The most commonly used is brown corundum, because brown corundum has high hardness, high toughness, and particle edge. Sharpness, strong applicability and lower price than other abrasives. How to choose the right grinding wheel? The choice of abrasive mainly depends on the workpiece material and heat treatment method.
When grinding materials with high tensile strength, choose abrasives with high toughness.
When grinding materials with low hardness and large elongation, select brittle abrasives.
When grinding materials with high hardness, use abrasives with higher hardness.
Choose abrasives that are not easy to chemically react with the processed materials.
In order to give you a more intuitive view of the advantages of our cutting discs and the guarantee of quality, today I will take you to take a look at several other tests on the cutting discs.
It is well known that a good mesh has a great effect on the quality of the grinding wheel. The first thing we see is the measurement of the resin mesh. First take 10 samples and weigh them, measure the inner and outer diameters of the mesh, and select the mesh according to the requirements of different types of grinding wheels to effectively improve the strength of the grinding wheel.
We then tested the resin viscosity according to “GBIT2794-1995 Adhesive Viscosity Test”. Here you can see that our inspectors first use a beaker to measure an appropriate amount of resin liquid, keep the temperature of the resin liquid at 25°C, and measure the viscosity with a rotary viscometer. The higher the value, the thinner the viscosity. The viscosity of the resin liquid of the sample is Within a reasonable range, 1525 can effectively combine various materials of the grinding wheel and improve the strength. Therefore, the viscosity index of the resin liquid is an important indicator of the strength of the grinding wheel.
Then according to “GBIT2493-2013 Grinding Wheel Rotation Test Method”, let us test the strength of a good grinding wheel. The rotation test of the grinding wheel helps us understand the limit of the grinding wheel during the rotation process and prevent the later generation of the grinding wheel bursting. The problem, for example, the standard crushing limit of the grinding wheel of the sample CNDOME 125×1.0x22 cutting disc in the video is 22979 revolutions, while the actual crushing speed is 31620 revolutions. This shows that the quality of our grinding wheels is much higher than the standard products, and the performance is excellent!
Finally, let’s take a look at the degree of decline of our grinding wheels. Take 10 pieces of the same batch of products and divide them into two groups for decay experiments. The first group of 5 pieces is put into a constant temperature and humidity machine for decay simulation, set the temperature to 49 ℃ and humidity 90%, and take it out for cutting test after 24 hours. The second set of cutting data comparison of the grinding wheel for the recession test, the video cutting the grinding wheel for the recession test cuts 100 knives, and the recession test is 143 knives, and the recession is 30%. The recession experiment can help us understand the grinding wheel more effectively. Changes in a cycle to improve performance.The selection of our raw materials is checked at various levels to ensure that each piece is of high quality.
The cutting disc is divided into ordinary, neutral and super heavy-duty models. The difference lies in its durability. Different cutting discs have different specifications and models. There are many different types of cutting discs on the market. The full diameter of our grinding wheels can be customized, from 3 inches to 16 inches. The specifications of the cutting blades produced by different cutting blade manufacturers are different, but they have a common feature, which is composed of three parameters. These three parameters represent the outer diameter, thickness and aperture of the cutting blade, such as a certain type of cutting blade. The specifications are: 400*1.2*32, which means that the outer diameter of the cutting disc is 400mm, the thickness is 1.2mm, and the aperture is 32mm. The main models are: 400*3.2*32, 350*3.2*25, 300*3.2*25, 250*2*25, 180*3*22, 150*3*22, 125*205*22, 100*205* 16, 125*1.2*22, 107*102*16. Interested customers can contact us directly.
