The hardness of the abrasive tool refers to the difficulty of the abrasive particles falling off the surface of the abrasive tool under the action of external force. The hardness of the abrasive tool mainly depends on the amount of bonding added and the density of the abrasive tool. The abrasive particles are easy to fall off, indicating that the hardness of the abrasive tool is low, on the contra...

Hardness is the main characteristic that determines the performance of abrasives. The super-hard abrasive itself has extremely high hardness, so it can process a variety of high-hardness materials, especially those that are difficult to process with ordinary abrasives. For example, use diamond abrasive tools to process cemented carbide, ceramics, agate, optical glass, semiconductor materials, ston...

Features It uses a unique resin binder, so it has better flexibility and is very easy to use and install. The strength of the entire grinding force is higher, because the polishing speed is very fast, so the gloss is also high. The wear resistance of the dry diamond disc is very good, and the most important thing is that it has a long service life. There will be no residue or staining on the groun...

Abrasive is the main material of abrasive tools. When using abrasive tools for grinding, it acts as a cutting edge. Among the elements that constitute the abrasive tool, it is the key element for whether the abrasive tool can be ground. The physical and chemical properties of abrasives also have a significant impact on the manufacturing process of abrasives. Since ceramic abrasives need to be fire...

Classification of metal bond The main types of metal bond are bronze bond, tungsten-cobalt alloy bond, nickel-cobalt alloy bond and cemented carbide bond. The superhard material metal bond abrasive tools can be divided into two categories: abrasive tools and other tools according to their processing objects and scope of use. The bond of abrasive tools is mainly bronze bonding agent. Features of me...

The volume content of diamond in the PCD layer of the polycrystalline diamond composite sheet should account for more than 98%, and the rest is the catalyst metal diffused and infiltrated from the cemented carbide base. Therefore, the quality of diamond powder plays a very important role in determining the final performance and consistency of the sintered product. Generally, the diamond powder use...

As the current applied technology of polishing materials has not yet reached a high level, the workpiece to be polished and the polishing material itself are still the main factors affecting the polishing quality. A high-quality workpiece to be polished is a prerequisite for obtaining a good polishing effect. If there are impurities in the workpiece to be polished, no matter how good the poli...

Diamond particle size The commonly used diamond particle size is in the range of 30/35 to 60/80. The harder the rock, the finer grain size should be selected. Because under the same pressure conditions, the finer the diamond, the sharper it is, which is conducive to cutting into hard rocks. In addition, generally large-diameter saw blades require high cutting efficiency, and coarser particle size ...
