Grinding wheel grinding tools are an indispensable tool for grinding. Many people don't know much about it. In fact, there are many kinds of flat cutting disc on sale. Let's take a look at the grinding wheels commonly used in daily life: Generally, the abrasives commonly used in the flat are brown corundum and white corundum, followed by black silicon carbide and green silicon carbide, and the other commonly used are chrome corundum, single crystal corundum, microcrystalline corundum, zirconium corundum, and corundum. 1. Brown corundum: Brown corundum has high hardness and high toughness. It is suitable for grinding metals with high tensile strength, such as carbon steel, alloy steel, malleable cast iron, hard bronze, etc. This kind of abrasive has good grinding performance and wide adaptability. It is often used to remove a large amount of coarse grinding, which is cheap and can be widely used. 2. White corundum grinding wheel: The hardness of white corundum is slightly higher than that of brown corundum. The toughness is lower than that of brown corundum. When grinding, the abrasive particles are easily broken. Therefore, the grinding heat is small, and it is suitable for manufacturing fine-hardened steel and high carbon. Steel, high-speed steel and grinding wheels for grinding thin-walled parts are more expensive than brown fused alumina. 3. Black silicon carbide: Black silicon carbide is brittle and sharp, and its hardness is higher than that of white corundum. It is suitable for grinding materials with low mechanical strength, such as cast iron, brass, aluminum, and refractory materials. 4. Green silicon carbide: Green silicon carbide has higher hardness and brittleness than black silicon carbide. It has sharp abrasive grains and good thermal conductivity. It is suitable for grinding hard and brittle materials such as hard alloys, optical glass, and ceramics. There are many types of grinding wheels, and there are various shapes and sizes. Due to the different abrasives, binder materials and grinding wheel manufacturing processes, various grinding wheels have different working performances. Each type of grinding wheel has a certain range of application according to its own characteristics. Therefore, when grinding, it is necessary to select a suitable grinding wheel according to the specific situation. What kind of diamond cutting pieces can be divided into? The diamond cutting piece is a category that is separated from the cutting piece according to the material, and the cutting piece can be divided into three different types, and the specific classification is as follows: 1. Cutting head type cutting piece: the sawtooth is broken, the cutting speed is fast, and it is suitable for dry and wet cutting methods. 2. Continuous edge saw blade: continuous sawtooth diamond cutting piece, generally made by the sintering method. The commonly used bronze binder is used as the base carcass material. Water must be added during cutting to ensure the cutting effect, and the type of slit is cut by the laser. 3. Turbine type cutting piece: Combining the advantages of the two types of standard cut off wheel for metal in the front, the sawtooth continuously presents a turbine-like uniform convex and concave, which improves the cutting speed and increases the service life. These three diamond cutting discs have their own characteristics, and the applicable fields are also different. You can choose according to the specific cutting content.
