Vacuum brazed diamond grinding wheel

---

Diamond tool is a kind of tool with certain shape, performance and use, which is made of diamond as cutting and grinding material and with the aid of bond or other auxiliary materials. Diamond tools have been used in all walks of life.
In the stone processing industry, the main diamond tools are diamond circular saw blade, grinding wheel, roller, grinding block, rope saw, frame saw, etc. These tools are widely used in the exploitation, cutting, finishing and grinding of marble and granite.

In the field of geological and engineering investigation, various bits made of diamond are widely used. Such tools are widely used in drilling and exploitation of petroleum, metallurgy, non-metallic mines, geology, coal fields, geothermal energy, etc., as well as in the construction and drilling of hydropower projects, bridges, wharves, large-scale construction projects and railway and highway projects.

In the machining industry, synthetic diamond is used to make various tools, molds, cutting tools, abrasives and measuring tools. The cutter can turn non-ferrous materials at high speed with low roughness and high precision. The molds used for grinding wheel, grinding wheel, oilstone, emery cloth, sandpaper, grinding paste, etc. have high grinding finish, high working efficiency, low processing cost and long service life.

In the construction industry, diamond tools are widely used to cut and drill concrete, such as the cutting of thermal deformation expansion joints in airports, bridges and highways, and the drilling of building installation.

In glass and ceramic processing industry, diamond tools are used for cutting, processing and edging of non-metallic materials.

In the field of metal products, diamond is mainly used as drawing die tools of various specifications.

In medical treatment, it is widely used in all kinds of dental tools, orthopedic tools, cosmetic tools and medical probes.

In addition, diamond can also be used to make diamond cutters, Vacuum brazed diamond grinding wheel, diamond phonographs, diamond nozzles, bearings in clocks and precision instruments, indenters of hardness meters, measuring heads of surface finish testers, indenters of high-pressure chambers, cutting and grinding all kinds of semiconductors and crystals, and heat sinks of semi conducting lasers, solid-state microwave devices and electronic heating devices.

According to different binders, diamond tools can be divided into the following categories: metal bonded diamond tools, electroplated bonded diamond tools, ceramic bonded diamond tools, resin bonded diamond tools, etc.

Metal bonded diamond tool is a kind of powder metallurgy product, which is made of diamond as cutting and grinding material, Vacuum brazed diamond grinding wheel, metal powder as bonding agent, by means of powder metallurgy, through pressing, sintering and necessary processing. Metal bonded diamond tool is the earliest one among all kinds of diamond products, and it is also the one with the most varieties, the largest amount and the widest use at present.

Electroplated metal bonded diamond tool is a kind of product which is embedded one or several layers of diamond firmly on the metal substrate through electroplated method and metal electrodeposition process. The main products are electroplated diamond files, electroplated saw blades, electroplated thin wall drills, electroplated dental drills, etc.

The ceramic bond diamond tool is formed by using the mixture of abrasive (diamond, silicon carbide, etc.), glass material (boric acid, zinc oxide, quartz, mica, etc.), non glass material (clay, Al2O3, etc.), colorant (Fe2O3, green plus Cr2O3, etc.), temporary binder (dextrin, water glass, high molecular resin, etc.) and manufacturing process of molding, sintering, trimming, sharpening, etc. Diamond grinding tools. It is characterized by good chemical stability, small elastic deformation, large brittleness and wide range of allowable hardness change.

Resin bonded diamond tool is a kind of diamond grinding tool with a certain shape, which is made of resin powder as bonding material and filler material through hot pressing, solidification and machining. Resin bonded diamond tools are widely used in machining industry because of their good elasticity, impact resistance, self sharpening and high grinding efficiency.
