Abrasives is a general term for abrasives and abrasives, including abrasive products and abrasive products. Abrasives are known as industrial teeth. In grinding, abrasives or abrasive tools are often used as grinding tools to machine workpieces to meet certain technical requirements. Commonly used abrasive mills include cut-off wheels and grinding wheels, grid wheels, quick-change grinding […]
Among them, abrasive products are mainly divided into two categories: corundum abrasives and silicon carbide abrasives. Specifically, there are basically the following: 1. Brown corundum abrasive, the main component is Al2O3, with medium hardness, high toughness, sharp particles, relatively low price, suitable for processing high tensile strength metals. Microcrystalline corundum abrasives and black corundum abrasives […]
Grinding wheel is the most important type of grinding tool in grinding. The grinding wheel is a porous body that is prepared by adding a binder to an abrasive, compacting, drying and calcining. Due to different abrasives, binders and manufacturing processes, the characteristics of the wheel vary greatly, which has a major influence on the […]
1. According to the abrasive used, it can be divided into ordinary grinding wheel (corundum and silicon carbide) and natural abrasive superhard grinding wheel and grinding wheel (diamond and boron nitride cube wheel, etc.). 2. According to the shape, it can be divided into flat grinding wheel, chamfering grinding wheel, cylindrical grinding wheel, cup-shaped grinding […]
The grinder is mainly composed of a base, a grinding wheel, an electric motor or other power source, a bracket, a protective cover and a water supply device, and the grinding wheel is arranged on the upper surface of the base and on the inside of the base has a power source to receive the […]
1. Labor protection supplies must be in place before work to check whether the equipment has a qualified grounding wire. 2. To check whether the grinding wheel cutting machine is intact, if the grinding wheel has crack defects, it is forbidden to use sick equipment and unqualified grinding wheel. 3. When the material is cut, […]
Abrasives are hard, sharp materials used to polish softer surfaces. Abrasives are available in two categories: natural abrasives and synthetic abrasives. According to the hardness classification, there are two categories of super-hard abrasives and ordinary abrasives. Abrasives range from the mildest household detergents to the hardest material gemstone and diamond abrasives. Abrasives are essential to […]
The chemical composition of natural corundum is alumina, which is mainly produced in South Africa, which is used for polishing and grinding glass. Emery is also a natural form of alumina. In general, it is not as pure as corundum. Its main producing areas are Greece and Turkey. It is mainly used to make abrasive […]
Since the 1970s, man-made abrasives have been mass-produced, the most important of which are tantalum carbide and alumina. Carbide is commonly known as emery. Pure vermiculite is mixed with coke and added with a small amount of wood chips. It is placed in an electric furnace and calcined between 2,200 and 2,480°C for approximately 36 […]
One of the important properties of an abrasive is its hardness, which must be harder than the material to be processed. Mohs hardness tester is commonly used to determine the hardness of various abrasives. Another important property of abrasives is toughness or resistance to bulk. The mixing amount, purity, particle size and crystal structure of […]
