Tungsten carbide insert

Our cutter is our most advanced PDC cutter at present. Developed in 2006 and has been made several important technical improvements. The advantages of the new cutter are based on the improvement of the technology, which has completely updated in several factors:
1. The diamond powder is selected in a higher degree.
2. The claws of the interface are changed to be net-grooves-shaped which formed by 20 straight vertical grooves, and the depth of the grooves are shallower.
3. Improved the interior structure of the sintering cell that makes the pressure and temperature to be more uniform. It is very important for the PDC sintering.
4. Using new super heat-resistant metal, to avoid being contaminative during sintering.
5. The sintering processing is amended, and the bonding strength of the diamond-diamond key among the diamond layer is improved
6. Increase the content of diamond, and increase the thickness of diamond layer up to 2.0mm.

Our company has in its possession an advanced production line for manufacturing dies and moulds and a production line for post machined cemented carbide products. We can also supply tailor-made products of various specifications based on the requirements of our customers.
Tungsten carbide is more expensive per unit than other typical tool materials, and it is more brittle, making it susceptible to chipping and breaking. To offset these problems, the cemented carbide cutting tip itself is often in the form of a small insert for a larger tipped tool whose shank is made of another material, usually carbon tool steel. This gives the benefit of using tungsten carbide at the cutting interface without the high cost and brittleness of making the entire tool out of carbide. Most modern face mills use carbide inserts, as well as many lathe tools and end mills. In recent decades, though, solid-carbide end mills have also become more commonly used, wherever the application's characteristics make the pros (such as shorter cycle times) outweigh the cons (mentioned above).

Because of its high precision and high reliability, tungsten carbide inserts have been broadly used worldwide for significant productivity improvements. With different application, the inserts are sorted as wood-cutting tools, clamped inserts, milling & turning inserts, etc.
