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 ...

The exposure or protrusion height of diamond on the cutting surface of the sawing tool will affect the cutting depth of each particle, that is, the material removal rate of the cutting tool. The use of diamonds with larger particle size will have a faster material cutting rate. Generally coarse particles are used for cutting soft materials, while smaller particle sizes are used for cutting hard ma...
