Among the superhard materials, diamond is a kind of superhard material, and the other is cubic boron nitride. After a series of processing and processing procedures, the two superhard materials can be made into various tools and directly used to make various functional devices, which are collectively referred to as superhard material products. Here we focus on one of them - diamond grinding tool.
What Is A Diamond Tool?
Diamond tool is a cutting, grinding or polishing tool with diamond grains fixed on the working parts of the tool via some kinds of bond materials or by some other special means. Diamond tools is suited for cutting,
grinding, drilling and polishing hard abrasive materials, such as stone, concrete, ceramics, bricks, glasses, fire-proof materials and other similar materials. Important note: diamonds should not be used for cutting steel or iron, as carbon will dissolve into the workpiece and lead to tool wear and work hardening.

There are two types of diamonds: natural and man-made. It is the hardest substance and has the strongest ability to refract light, so large-grained natural diamonds have long been the "king of gems". Diamond also has the highest strength, thermal conductivity, and sound velocity among known materials, small sliding friction coefficient, chemical stability, hydrophobicity, thermal stability, and graphitization. Mainly by the following categories: sawing tools, drilling tools, superhard tools, dressing tools and wire drawing dies.
Using diamond abrasive as raw material, metal powder, resin powder, ceramic or electroplating metal are used as binders respectively, and the circular bonded grinding tool with a through hole in the center is called diamond grinding wheel. The structure of diamond grinding wheel is generally composed of three parts: working layer, matrix and transition layer. The working layer, also known as the diamond layer, is composed of abrasives, binders and fillers, and is the working part of the grinding wheel. The transition layer, also known as the non-diamond layer, is composed of binder, metal powder and filler, and is the part that firmly connects the diamond layer to the substrate. The base body is used to receive the abrasive layer, and is firmly clamped on the main shaft of the grinding machine with a flange plate when in use. Generally, the metal bond products use steel and alloy steel powder as the base; the resin bond uses aluminum alloy and bakelite as the base. It is processed by aluminum, steel or bakelite, and plays the role of supporting the working layer and installing the grinding (tool) tool. The quality of the grinding wheel forming and the accuracy of the use have a lot to do with the matrix.
A diamond grinding head is a grinding tool for non-metallic materials such as stone and ceramic materials, especially a grinding tool with a diamond alloy as the grinding body. It is fixed in the base body, and the grinding body is also arranged in a gap on the grinding surface of the grinding head, wherein the base body is preferably made of a bonding material with certain toughness, and the grinding body is preferably made of diamond alloy material. The new type has the characteristics of high grinding performance, simple manufacture and low cost, high grinding quality and suitable for large-scale grinding.
The flexible diamond abrasive product is a new type of coated abrasive tool developed and manufactured with artificial diamond and cubic boron nitride as raw materials and a new process method. Flexible super-hard abrasive products include: abrasive belts, sand sleeves, sand discs, sand sheets, sponge hand wipes and other forms. Flexible diamond and cubic boron nitride products are widely used in grinding and polishing stone, glass, ceramics, synthetic materials, cemented carbide, non-ferrous metals and iron-based alloys and other hard materials. Due to its high hardness and high single-piece compressive strength, superabrasives have the advantages of high grinding efficiency, low grinding temperature, good workpiece surface quality, and stable grinding performance. Diamond abrasive belts have been proven to be very cost-effective for automotive glass and high-grade glass. It has better grinding force, kiss and force, better chip removal and heat dissipation than traditional diamond grinding wheels.
Diamond sawing tools mainly refer to various diamond cutting saw blades, including circular saw blades, gang saws, band saws, wire saws, etc. Mainly used for cutting non-metallic materials such as marble, granite and concrete.
Drilling tools mainly include synthetic diamond geological drill bits, oil (gas) well drill bits, and engineering thin-wall drill bits, which are respectively used for geological exploration, oil (gas) exploration and exploitation. Drilling holes in various buildings. In the industrial application of synthetic diamonds, geological drill bits are one of the most important products. The types of drill bits can be roughly divided into: core drill bits; full-section drilling bits; engineering drill bits, etc. Among them, the most widely used is the geological exploration core drill, which can be divided into impregnated drill bits and surface inlaid drill bits. Its manufacturing methods include hot pressing, dipping, cold pressing and sintering, and electroplating.
