?In the last article - the basic knowledge of the
high performance cutting disc, we have already shared some knowledge of the grinding wheel abrasives. In order to let everyone know more clearly what is the abrasive of the grinding wheel, this article will focus on what is the abrasive material of the
thin flat cutting disc.
The grinding wheel can be used for grinding because the grinding wheel is a small particle bonded together by a bonding agent. This small particle has certain characteristics and can be rotated to have a certain grinding effect. These small particles one by one are abrasives. Different types of abrasives have different properties and are suitable for grinding different products. As mentioned in the basic knowledge of grinding wheels, abrasives for grinding wheels can be divided into two types of super-hard material grinding wheels and ordinary grinding wheels. There are also different sub-projects under super-hard material grinding wheels and ordinary grinding wheels:
Abrasives have different properties and are suitable for grinding different products. The choice of abrasive for the grinding wheel needs to be determined according to the workpiece material processed by the customer. For example, diamond is suitable for grinding hard alloy products, and CBN is suitable for grinding high-speed steel products. When selecting abrasives, if you are not sure, it is best to ask a professional.
The organization of the grinding wheel reflects the proportional relationship between the abrasive particles, the binder, and the pores. The larger the proportion of abrasive grains in the total volume of the grinding wheel, the tighter the structure of the grinding wheel and the smaller the pores; on the contrary, the smaller the proportion of the abrasive grains, the looser the structure and the larger the pores.
The level of grinding wheel organization can be divided into three categories: compact, medium and loose. The subdivision can be divided into 15 levels. The organization number can be understood as the porosity. The tightly organized grinding wheel is suitable for grinding under heavy pressure. In the case of profile grinding and precision grinding, the tightly organized grinding wheel maintains the formability of the grinding wheel and achieves a low roughness. Medium-sized grinding wheels are suitable for general grinding operations such as grinding of hardened steel and sharpening of tools. The grinding wheel of the loose structure is not easy to be blocked and is suitable for a process of grinding a large contact area such as a surface grinding machine, an internal grinding machine, and grinding heat sensitivity.
