Tungsten carbide tools

Tungsten carbide tools for cutting are used in machines that are intended to get into contact with carbon steel and stainless steel. Most of the time tungsten carbide is used as the first material to run through a surface, leaving a finer finish for other machines. In situations where high exposures to high temperatures are to be expected, tungsten carbide tool is employed since it can withstand extremely high temperatures that would melt industry strong steel or other metals. In such situations, the tungsten carbide is referred to as cemented carbide. During manufacture, cobalt is melted and once in the liquid stage, the cobalt combined with tungsten carbide alloys or particles, which act as the aggregate while the cobalt, forms the metal matrix composite. This process is called sintering or hot isostatic pressing. Addition of the naturally ductile cobalt metal goes a long way to ensuring that the tungsten carbide exhibits the characteristic brittle behavior. This process raises the durability and toughness of the final product. Machining of tungsten carbide tools is a difficult undertaking since the carbide tends to be brittle compared to other tool materials. As a result, it is prone to breaking and chipping. To counteract this problem, manufacturers have resorted to selling carbide inserts or simply carbide tools matching insert holders. With this configuration, the tungsten carbide insert is held firmly in place by the larger tool that is made of less brittle material. This combination is usually between tungsten carbide and steel. This arrangement has the benefit of incorporating carbide use without having to worry about the high cost of manufacturing the entire tool purely of tungsten carbide. Most modern face mills are using tungsten carbide inserts as well as some lather tools and end mills. To increase their lifespan, the tungsten carbide tools are coated with Tin, Tic or TiAIN. Most of these coatings have enabled the carbide tools to be harder and/or have more lubricity. Use of a coating also has the advantage of lowering the temperature associated with the cutting and it increases the life of the tool under use.

Tungsten carbide tools have many applications based on the industries that use carbide equipment and other hard materials like diamonds. Tungsten carbide is especially used in sharpening of blades used in industrial applications. These tungsten carbide blades are used to improve versatility and productivity when sectioning plastic. During these cryo applications, the tungsten carbide blade is embedded in a holder made of steel. The blades are consistent and can survive through thousands of applications eliminating the need for frequent changes. The knives are also easy to handle and the risk of cuts is drastically reduced when compared to glass and razor or diamond blades. Its application is also seen in the making of nozzles in varying industry standards. Discharge units are easily manufactured using tungsten carbide. Small and large tiles can be formed into any sharp to fit customized surfaces or edges with minimal effort while still maintaining the high quality standards.
