Aug 16,2021

In recent years, as the applications of diamond tools have become increasingly widespread, their development has accelerated. Today, let's recall what diamond tools are present around us! Diamond tools refer to products made from diamond grit and micro-powder as cutting and grinding materials, aided by binders or other auxiliary materials, which have certain shapes, properties, and uses. Diamond tools can be classified by purpose into: (1) Abrasives including bonded abrasives, coated abrasives, and loose abrasives such as grinding wheels, sanding sheets, grinding stones, grinding heads, sand belts, polishing pastes, etc. (2) Cutting tools divided into two categories: one category is for cutting granite, marble, and concrete.

　　In recent years, as the applications of diamond tools have become more widespread, their development has accelerated. Today, let's recall what diamond tools exist around us!

　　Diamond tools refer to products made from diamond grit and micro-powder as cutting and grinding materials, formed into specific shapes, performance characteristics, and uses with the help of binders or other auxiliary materials.

　　Diamond tools can be classified by their uses as follows:

　　(1) Abrasives: including bonded abrasives, coated abrasives, and loose abrasives such as grinding wheels, sandpaper, grinding stones, grinding heads, sanding belts, polishing pastes, etc.

　　(2) Cutting tools: divided into two categories: one for cutting granite, marble, concrete using circular saws, band saws, frame saws, rope saws; the other for cutting metal and semiconductor materials using inner circular cutting discs and outer circular cutting discs.

　　(3) Drilling tools: including drill bits and reamers used in geological exploration and mining in sectors like petroleum, coal mining, metallurgy.

　　(4) Cutting tools: made from polycrystalline diamond composite or natural single crystal to create turning tools, boring tools, milling cutters for precision machining of non-ferrous metal parts in automobiles, aircrafts and non-metallic materials like plastics and ceramics.

　　(5) Dressing tools: profiling dressing wheels, dressing pens, dressing blocks.

　　(6) Drawing dies: made from polycrystalline diamond to draw various metal wires such as electrical wires and filaments.

　　(7) Other tools: scribing knives, glass cutters, carving knives, set material knives, assorted files measuring instruments heads bearings phonograph needles diamond scalpels etc.

　　(8) Special instrument components: hardness tester pressure heads surface roughness gauge probes high-pressure chamber anvils internal combustion engine nozzles high-power transistors infrared windows microwave devices lasers diamond heat dissipation components in large-scale integrated circuits resistance thermometers etc.

　　Classified by manufacturing process:

　　1. Welding:

　　Laser welded products can be dry cut (i.e., operated without water).

　　High-frequency welded products can only be wet cut (operated with water).

　　2. Sintering:

　　Cold pressing: currently over 80% of domestic diamond tools are manufactured using cold pressing methods.

　　Hot pressing: sintering while applying pressure results in higher density tool tips with better cutting performance than cold pressed products.
