What carbide cutting tools, carbide cutting tools origin, today small to explain the following:

In 1923, Germany Shileteer to tungsten carbide powder was added into the 10% to 20% cobalt binder do, invented a new alloy of tungsten carbide and cobalt, hardness only to diamond, which is the world made of artificial into a first cemented carbide. When using this alloy tool steel cutting, the blade will wear quickly, even edge crack. 1929 United States 施瓦茨科夫 original ingredients added to the amount of titanium carbide and tungsten carbide duplex improved cutting tool steel performance. This is another achievement in the history of cemented carbide.
Carbide cutting tools can also be used to make drilling tools, mining tools, drilling tools, measuring measuring tools, wear parts, metal grinding, cylinder liners, precision bearings, nozzles, metal molds (such as drawing die, mold bolt, nut die, and excellent performance fasteners mold, replacing previous carbide steel mold).
The past two decades, coated carbide also come out. 1969 Sweden successfully developed titanium carbide coated tool, the tool substrate is a cobalt tungsten titanium carbide cutter or tungsten carbide cobalt, titanium carbide surface coating thickness of only a few microns, but compared with the same brand of alloy tool longer life three times, cutting speed increased by 25% to 50%. 1970s has emerged the fourth generation of coating tools used to machine difficult materials processing.
How carbide sintering?
Carbide is that one or more refractory metal carbides and binder metals, powder metallurgy method made of metallic material.
