High precision tungsten carbide flowdrill is well known as a drilling tool that can process holes on thin workpieces such as thin plates and thin tubes with advantages of high accuracy, high speed, beautiful surface, and low cost. Such a drill bit is wear-resistant and high-temperature resistant to be used at bad conditions. This drill bit uses the basic principle of generation of heat by friction to drill holes with bushings in tubular or plate metal workpieces, which is a…

Tungsten carbide flowdrill with double heads is solid, stable, wear resistant and high temperature resistant as it is made of high-quality cemented carbide material that mainly composed of tungsten carbide powder and cobalt powder. The flowdrill is mainly applied to a chipless drilling process – fdrill process. And such a flowdrill bit is suitable for processing ordinary steel, stainless steel, aluminum, copper and other workpiece materials that are malleable. Also, it can be used to drill electroplated workpieces. More details,…

What is working principle of tungsten carbide flowdrill? You know, tungsten carbide flowdrill is a wear-resistant and high-temperature resistant drill bit for flowdrilling processes. The flowdrilling process is a chipless machining technology that processes holes and bushes on a metal sheet or tube at one time. Such a process has completely replaced the process of welding and riveting a nut on a thin-walled workpiece. Therefore, it is necessary for us to understand the working principle of flowdrill. More details, please…

Tungsten carbide graver is also known as cemented carbide graver, which has higher hardness, better wear resistance and longer service life than the commonly used carbon steel graver and white steel graver. Wherein, carbon steel graver is generally suitable for beginners as it has low hardness and strength. More details, please visit: http://www.tungsten-carbide.com.cn/tungsten-carbide-blade-bar.html The tungsten carbide graver can be made of carbide materials such as YG8 – has good wear resistance, hardness of 8-9, and density of 14.5-15.9. What should…

New tungsten carbide glass cutter adopts a tungsten carbide substrate as the cutter body. And it is coated with a diamond-like coting of thickness of 1-10 microns. The diamond-like coating on new tungsten carbide glass cutter can improve the hardness and wear resistance of the cutting edge. When cutting hard glass, the coating film can significantly increase the life of the glass cutter. More details, please visit: http://www.tungsten-carbide.com.cn/tungsten-carbide-blade-bar.html So, why choose a diamond-like coating instead of a diamond coating? The…

Tungsten carbide glass cutter is a tool used for cutting or scoring glass such as LCD optical glass, quartz glass, and crystal glass. There is a small wheel of tungsten carbide materials. Such a glass cutter has the characteristics of high hardness, good wear resistance, straight scribing, no edge collapse and long service life. More details, please visit: http://www.tungsten-carbide.com.cn/tungsten-carbide-blade-bar.html Compared with traditional glass cutters, tungsten carbide glass cutters have sharper cutting edges, higher efficiency, smoother cut surface without scratches and…

Tungsten carbide cutting wheel is mainly composed of a WC hard phase and a Co bonding phase, which is suitable for cutting brittle materials such as ceramic tiles, glass, glazed tiles, polished tiles, etc. More details, please visit: http://www.tungsten-carbide.com.cn/tungsten-carbide-blade-bar.html What Is Tungsten Carbide Cutting Wheel? It is a super-precision disc-shaped tool that can form a deep slit on the workpieces to be cut so as to break the workpieces along the slit and form a reliable vertical cutting surface when…

Tungsten carbide scriber is a fitter tool that is mainly applied for scribing on the surface of different workpieces such as steel plates, and ceramic tiles. The scriber made of high quality tungsten carbide is often used in conjunction with guide tools including steel rulers and scribing templates, etc. More details, please visit: http://www.tungsten-carbide.com.cn/tungsten-carbide-blade-bar.html In the past, scribers were mostly made of spring steel wire or high-speed steel, but these scribers had poor wear resistance and short service life, so…

Tungsten disulfide is a new type of graphene-like two-dimensional material, which has great application potential in electrical devices, energy, biology and composite materials. More details, please visit: http://tungsten-disulfide.com/index.html As research on new graphene-like two-dimensional material is getting more and more important, preparation of WS2 is also a research hotspot. At present, preparation methods of two-dimensional WS2 include mechanical stripping, electrochemical lithium ion intercalation method, liquid phase stripping method, hydrothermal method and chemical vapor deposition (CVD) method. Wherein, CVD method has…

How to prepare tungsten disulfide nanoparticles? At present, the flower-shaped WS2 nanoparticles are mainly prepared by hydrothermal method. While this method has the disadvantage of low yield, which is not conducive to mass production. So, some experts have proposed a simple process – high temperature vulcanization method – to prepare flower-shaped WS2 nano particles. The high purity WS2 nano particles are prepared by this method with low cost and high yield, so it is expected to be used in large-scale…
