Why Carbide Becomes A Good Tool To Work With?

By Jamal D White


You may often that manufacturer's keep looking for searching materials that they can use to make better machining tools. Offering more efficiency, productivity and of course quality to the customer is what makes the company thrive towards success. Likewise, there are different tools that are used for the manufacturing or production of machining tools.

Carbide cutting tools are the tools, which have their ends or the tool tip made up of carbide. As the carbide is one among the strongest materials, they are used to cut the hardest materials or workpieces. The invention of carbide did change a lot of things. Carbide is a compound not a purely metal; it is an alloy of carbon and another nonnegative element. Carbide is also considered as a derivative of hard metal and it is something that has revolutionized the industry, as the hard metal was something that every industry had to offer.

There are several benefits of using the tungsten carbide instead of other alloys and even the pure metals. It is found that carbide is thrice as strong as steel in comparison and is also a lot denser than steel or titanium.

The hardest carbide substance that came into existence for cutting harder material is the Tungsten carbide, which was found in the early 1900s. It was then followed by the introduction of carbide cutting tools. Industries have become more focussed on producing tools that consists of carbide and in the modern times, we are able to benefit greatly from it.

There are different manufacturers that make use of different types of carbide tools used for machining that are made of metal and preferred for their finishing capability. Irrespective of the type of tools or machines being manufactured, the ones that have the best finishes are considered as the best quality tools.

Even a slight chip in the material is going to affect the life of the cutting tool, it reduces it significantly. This is the reason, all the new carbide tooling equipment comes in individual plastic tube, the regrinds are found to be dipped into wax coating and it helps it to protect the delicate cutting edges. You may also find a majority of the machining manufactures; treat their carbide tooling equipment, once they have decided it ready for re-sharpening.

Next is the green state machining, which is a part of the process that occurs during the manufacturing of the tungsten carbide. During the process there is a time where the powder is in a soft form, which can be shaped in the form you want. After this the material shrinks and the edge changes. If proper finished edges are required, the carbide is taken for the grinding process for proper edge definition. It is comparatively a longer process and does increase the labour cost.

Also keep in mind, in case there is more damage caused to the tool, due to handling and banging the cutting edges. This means there are more materials that are to be removed to get the sharpness again. However, this might result in fewer regrinds, shorter cutting length and shorter tool life.It is also recommended to ensure all the end mil tools that are ready for re-sharpening or complete new, are kept in original plastic case and not thrown in a pile for regrinding.
