In recent years, a variety of new tool materials endless, but tungsten carbide cutting tools will still be widely used in the future for a long period of time, it is necessary to study the development of new materials preparation technology to further improve and increase the tungsten carbide tool material’s cutting performance.

The strength and abrasion resistance of tungsten carbide cutting tools can be improved by refinement of hard phase grain size, increase of hard phase inter-granular surface area and enhancement of inter-granular bonding force. When the WC grain size reduced to sub-microns, the hardness, toughness, strength, wear resistance, etc. can be increased, and the required temperature can be fully densified. General tungsten carbide grain size is 3 - 5μm, fine-grained tungsten carbide grain size is 1--1.5μm (micron), ultra-fine tungsten carbide grain size can be up to 0.5μm (Micron, nanoscale).

As the grain refinement process is still not mature enough, so in the sintering process of tungsten carbide sintering is easy to grow into coarse grains, and grain growth will lead to the general strength of the material decreased, a single coarse WC grains are often Causing an important factor in material fracture.

In the development processing, tungsten carbide encountered contradiction between strength and hardness, which is with high hardness but low strength, high strength but low hardness. WC particle size of tungsten carbide is always greater than its original particle size with traditional methods, and usually in a few microns.

However, many countries have encountered difficulties in the study of nano-carbide, the main problems are reflected in two aspects: First, the preparation of nano-WC-Co composite powder activity is very sensitive to temperature, in the high temperature will be immediately grown up. The current research and development trend is to improving the preparation of ultra-fine WC-Co composite powder method and improve the sintering processing. The compactness and uniformity of the tungsten carbide prepared by low pressure isostatic pressing sintering process are well, and the process has the advantages of short production cycle and small process loss.

China's financial services authorities required major executives of the Shanghai-based bitcoin trading platform BTCC on Friday to rectify misbehavior in the trading of the virtual currency - and to raise awareness of risks as the value of bitcoins experienced wild fluctuations.

Mobile emission catalyst helps in emission reduction from automotive and stationary engines from many vehicles such as cars, trucks, commercial vehicles and buses. It reduces emission of various gases such as carbon dioxide (CO2), carbon mono oxide (CO), hydrocarbons (HC), oxide of nitrogen (NOx) and other gases which are produced due to incomplete combustion of fuel. 

In the field of armor piercing, the United States is well ahead of all the countries in the world - including tungsten alloy armor piercing projectiles.

It is reported the world’s highest bridge, named Beipanjiang Bridge, is open to traffic on Dec. 29, 2016. The bridge connects Guizhou and Yunnan, China. It has been the highest bridge all around the world for the bridge is 565meters again the river surface, with total length of 1341.40meters. The heights of east and west bridge piers are 269meters and 247meters. It took four years to finish such a bridge with many difficulties.

As technology advances, the traditional thread turning process can not meet our processing needs as follows:
1. Large weight, large parts can not be installed in the lathe;
2. Blind hole difficult turning machining thread;
3. Shaped workpiece in the lathe difficult to clamp positioning;
4. Processing large-size thread when the efficiency is too low;
5. The processing efficiency of the material is very low and difficult tool life is very short;
6. Lathe strength can not meet the turning requirements;
7. Broken chip, such as bad or difficult chip.

In this context, tungsten carbide indexable thread milling cutter came into being. Its advantages are: thread milling can achieve heavy cutting, high-speed cutting, can be difficult to complete the cutting of materials, with high processing efficiency, high thread quality (can achieve low surface roughness), tool versatility, processing security Can be significantly reduced user cost of the tool, with only one tool can produce the same pitch but different diameter of the thread, and in any thread tolerance within the manufacturing process. Not only reduces the user machine tool share, and processing efficiency increased exponentially. The tool is the processing of stainless steel, cast iron, cast steel, high strength steel and nonferrous metals and other materials, high-precision milling thread cutting tools. The product type covers all standard thread types, can be installed on the standard cutter bar, and available from stock.

At present, China's thread processing generally stagnant in the processing of traditional turning. Tungsten carbide indexable thread milling cutter successfully developed and applied in production, to fill the gaps in domestic thread milling tool zero, breaking the monopoly of foreign enterprises for a long time, so that China's thread processing technology to a new level, This is of great significance to the development of China's manufacturing industry.

The past Christmas Russian President Vladimir Putin sent his warm Christmas and New Year greetings to president-elect Donald Trump while again urged Trump "to take real steps to restore the framework of bilateral cooperation".

Trump then gave a response with highly compliment of Putin’s view: ‘Putin has exactly the right thought, I do hope Russia – U.S. can act like this to save another unnecessary path’.

Tungsten is adecent carbide well utilized as a part of rapid steels and hot framing apparatus steels, maintenance of hardness and high temperature quality of the matrix. It is a steel dark metal that expands temperature and red hardness, improves growth and enhances durability of steels.

Ultra-low profile tungsten carbide gripper inserts are designed for ultra-low profile 0.14" (3.5mm) clamping with no dovetail workpiece preparation. These patented triangular grippers feature two rows of teeth at different angles with a 5° taper to maximize the pull-down effect, divide the clamping force, absorb vibration, and allow for high stability and secure workholding. Already integrated with the line of vises, the inserts are ideal for upgrading existing vise jaws and more.

With only 3.5mm of clamp surface needed to securely hold the workpiece, tungsten carbide gripper inserts are ideal for 5-axis machining operations. These durable inserts combine a tough-coated cemented carbide with specialized teeth and triangular shapes that penetrate materials including steel, hardened steel/titanium (up to 50HRC to 54HRC) and aluminum.

Tungsten carbide gripper inserts offer advantages over traditional clamping systems including exceptional clamping stability, no need for pre-machining or dovetailing workpieces, vibration dampening and allowing for very secure holding at lower clamping forces. This results in a higher cutting rate and less waste of materials than traditional clamping systems.
