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...

The polishing head of polishing material is often used in electric grinders, crane grinders, electric drills, etc. It is a small-scale grinding tool with a handle for polishing materials. Polishing material grinding head is mainly divided into: ceramic polishing grinding head, rubber polishing grinding head, diamond polishing grinding head, emery cloth polishing grinding head and so on. 1. Ceramic...

Idling: Especially when the new base is used for the first time, it needs to be idling for about 30 minutes. In the summer high temperature season, it needs to be idling with water. The purpose is to further eliminate the influence of the welding head on the base and enhance the saw blade to maintain its inherent quality under high-speed rotation memory. The blocks should not be less than 0.5m3 an...

After receiving the abrasive tool, carefully check whether there are cracks and other damages, and carefully check whether the relevant trademark signs on the surface of the diamond tools are correct, clear and complete. Grinding tools should be handled with care to prevent vibration and collision, and rolling on the ground is prohibited. Abrasive tools should be protected from moisture and freezi...
