What do diamond tools include?


In recent years, with the more and more extensive use of diamond tools, its development is more rapid. Today, let's recall what diamond tools are around us! Diamond tools refer to the products with certain shape, performance and use, which are made of diamond grain size sand and micro powder as cutting and grinding materials with the aid of bond or other auxiliary materials. Diamond tools are divided into: (1) Abrasives include consolidated abrasives, coated abrasives and loose abrasives, such as grinding wheel, sand tile, grinding stone, grinding head, abrasive belt, grinding paste, etc. (2) There are two types of sawing tools: one is the circular base for sawing granite, marble and concrete

Diamond tools refer to the products with certain shape, performance and use, which are made of diamond grain size sand and micro powder as cutting and grinding materials with the aid of bond or other auxiliary materials.


Diamond tools are divided into:


(1) Abrasives include consolidated abrasives, coated abrasives and loose abrasives, such as grinding wheel, sand tile, grinding stone, grinding head, abrasive belt, grinding paste, etc.


(2) There are two types of sawing tools: one is the circular base, band saw, row saw and rope saw for sawing granite, marble and concrete; the other is the internal and external circular cutting pieces for cutting metal and semiconductor materials.


(3) Drilling tools include drill bits, reamers and construction engineering drills used in exploration and development of geological, petroleum, coal, metallurgy and other departments


(4) The cutting tools are made of diamond polycrystalline composite chips or natural single crystals into turning tools, boring cutters and milling cutters, which are used to finish machining non-ferrous metal parts in automobiles, airplanes and precision machines, and non-metallic materials such as plastics and ceramics.


(5) Trimming tool shaping trimming roller, trimming pen, trimming block.


(6) The wire drawing die is made of polycrystalline diamond. It can draw wire, filament, screen wire, etc.


(7) Other tools such as scribing knife, glass knife, carving knife, nesting knife, assorted file, measuring head, bearing, stylus, diamond scalpel, etc.


(8) Special instrument components: hardness tester head, surface roughness tester head, high-pressure chamber anvil, internal combustion engine nozzle, high-power triode, infrared window, microwave, laser, diamond heat sink in LSI, resistance thermometer, etc.


According to manufacturing process:


1. Welding:


Laser welding products can be cut dry (i.e. without water).


High frequency welding products, only wet cutting (water operation).


2. Sintering:


At present, more than 80% of domestic diamond tools are made by cold pressing.


Hot pressing, sintering and pressing at the same time, high density of cutter head, cutting performance higher than cold pressing products.
