Given that tungsten carbide, a metal created by bringing together carbon and tungsten, is one of the toughest, most reliable and extremely durable metals you can find, it is not surprised that there are a great deal of usages for the metal. You can find it being used at home, for sports but there are also extensive military and industrial uses for tungsten carbide, making it an extremely versatile piece of metal. The strength of tungsten carbide is one of the strongest points of the metal and another thing that it is known for is the fact that there is a melting point that is extremely high. Using the Mohs scale, which is used to test hardness, the score achieved by tungsten carbide is 9. To put this into context, the only thing that has a higher score than tungsten carbide is a diamond, which manages to score a rating of 10. As the old saying goes it takes a diamond to cut a diamond but it also takes a diamond to cut tungsten carbide. You should be able to take this information and realise that the hard quality of tungsten carbide has a great range of benefits and the metal is extremely scratch resistant. The main use of tungsten carbide is cutting Given that it is scratch resistant and so tough, it makes sense that tungsten carbide is used extensively for cutting work. For high scale and serious cutting jobs, commonly found in the construction and mining industries, drills with a tungsten carbide tip can do a great job. It is reported that around 60% of all tungsten carbide material is used as cutting devices in these industries, indicating its importance to the economy. However, once you get beyond this major use, the use of tungsten carbide becomes far more widespread and the metal pops up in a lot of places that you would probably never think of. It stands to reason that tungsten carbide can be of benefit in razor blades although some people may think that it is too powerful a metal to be used. When used safely, tungsten carbide can help to make some of the most effective and efficient razor blades known to man. However, tungsten carbide is not just used for elements where cutting has to be carried out. You may be shocked to learn that tungsten carbide plays a key role in the development of so many different pieces of jewellery. Your first thought may be that something so tough and harsh is the last thing you would want to wear to look stylish but when you think about it more deeply, there are a number of benefits that can arise from using the material in this fashion. After all, so many pieces of jewellery become tarnished, scratched and ruined but this is not going to happen to a piece of jewellery that has been made from tungsten carbide. When it takes a diamond to cut or engrave these types of jewellery, you can rest assured that it will manage to stand up to the bumps and tumbles that come along with everyday life. Tungsten Carbide can also be used as extrusion dies, and wire drawing dies in wire drawing applications. You can find tungsten carbide around the home You will also find tungsten carbide being used in a simple manner in some of the most important items you will find in a house. Without light, a home would be a gloomy place to be and the invention of light bulbs helped to brighten up many a household. While light is the main energy that people notice from a light bulb there is an awful lot of heat generated from light bulbs, which makes tungsten carbide an essential component for light bulb filaments. Given the high level of heat that tungsten carbide can withstand, this makes them an obvious choice for creating light bulbs that can be used for a considerable period of time without being overly concerned about burn out. With tungsten carbide also being used in ballpoints to make sure that the ball is aligned with the ink, it would be fair to say that tungsten carbide is an essential part of everyday life. The uses of tungsten carbide are many but it would be fair to say that the benefits of tungsten carbide are fairly obvious. Tungsten Carbide, also called cemented carbide, can be used to machined as tungsten carbide parts, and carbide bush used in a wide range of industries such as automotive, aerospace, electronics manufacturing. This is a metal that can be relied upon regardless the situation or occasion. Whether you need something to withstand pressure, put up with excessive temperatures or even impact on other tough materials, tungsten carbide is the metal that can be relied upon time and time again. This is why it is the natural choice for so many manufacturers.

The punching tool is part of the typical industrial requirement and is usually manufactured by a tool-making company on a contract basis. Punching tools essentially consist of a punch, a die, and the stripper. What is a punch tool? The punching tool represents the technical basis for the separating process of punching and must meet high requirements in terms of load capacity, resistance and dimensional and shape accuracy. The punching tool is used to manufacture flat parts from various materials, for example, sheet metal. Technical basics of the punching process The punching can either be done manually or with the help of modern CNC technology. With manual punching, the sheet to be processed is first placed between the punch and the die. The punch is then guided onto the sheet metal with the aid of hydraulic or leverage with high pressure and cuts it at the interface between the punch and die. CNC punching machines also work according to this principle but carry out the individual process steps largely independently. The manufacturing process is usually divided into the types of shear cutting and wedge cutting, depending on the separation principle. During shear cutting, the pressure surface of the punching tool has a cutting edge that causes cracks to form and ultimately leads to the material tearing through. Wedge cutting, on the other hand, is characterized by two wedge-shaped cutting edges that cut through the sheet metal at a specific cutting wedge angle. Variants for punching tools Revolver punching machines use tools in which the punch sits in a sleeve that completely encloses it. It acts as a tool guide and scraper. The ram presses on the tool from above and drives the punch through the sheet metal. The plunger then moves upwards again by springs. In another variant, the tools are arranged like a matrix in several rows. In contrast to the turret plate, the tool magazine is not moved. Each magazine location has its own ram that can perform the punching process. Stamping tools are often used as progressive tools in complex stamping systems. When bending tools and cutting tools are used together, one speaks of the punching and bending process. Steel strips are unwound from a coil and fed into the hydraulic system; the punched sheets automatically go through a whole series of process steps. Sharp edges are often than ground off by tumbling. Compared to conventional punching tools, fine blanking tools are primarily characterized by the fact that they meet the highest requirements in terms of dimensional and shape accuracy. With the help of fine blanking tools, it is possible to make the cut surface of the workpiece to be machined smooth and free of tears. The associated manufacturing process is usually referred to as fine blanking or precision cutting. A typical area of application for fine blanking tools is the production of components with the highest demands on dimensional accuracy. This includes, for example, gears with modules from 0.2 to 10 mm and thin sheet metal from 1 to 10 mm. Toothed racks or similar machine elements are also manufactured using the fine blanking process due to the high demands. Often the accuracy achieved is so high that no further reworking is necessary. The structure of the fine punching tool differs from the conventional punching tool in that the tool has a special serrated ring plate. This is moved by the outer ram of the press with the upper part, while the cutting punch is actuated in a separate movement by the inner ram. The cutting process is carried out in a tensioned state. In addition to the serrated ring, the cutting gap is of particular importance in fine blanking tools. The cutting gap ensures the particularly smooth surface and is defined depending on the sheet thickness. In principle, triple-acting automatic punching machines are required to operate precision stamping tools. |
