In the past few years, quality and type of the PDC cutting teeth have undergone tremendous changes. If the twentieth Century 80's teeth and the teeth are compared, difference is very big. Because of the change of mixing process and manufacturing process, quality performance is better cutting teeth of today's more, make the anti erosion bit and impact resistance are greatly improved.
Engineers have to optimize and artificial diamond tungsten carbide film interface, in order to improve the toughness of cutting tooth. Layered diamond technological innovations are also used to improve the abrasion resistance and thermal stability of the product.
In addition to the development of the materials and manufacturing technology, PDC products in the tooth design technology and teeth has also achieved major breakthrough. Now, PDC has been used for the products cannot be applied before the area, such as more hard, abrasive stronger and changeable formation. This expansion into new areas, on diamond (fixed cutter) has a great influence between bit and rock bit balance.
