Problems solved by technology
However, the above-mentioned heterosexual diamond compacts cannot improve the grinding and drilling efficiency under the condition of satisfying the impact resistance in actual drilling (for example, the cone-shaped diamond compacts are mainly used in the rock breaking process and need to be completed in the rock breaking process. Then replace it with a flat diamond composite sheet to complete the cutting task)
In addition, there will be chipping or delamination of the special-shaped tooth mechanism during use, which will increase the resistance of drilling and cutting during use and reduce drilling efficiency

Abstract
The invention discloses a multi-surface arc-shaped diamond compact. The multi-surface arc-shaped diamond compact comprises a substrate and a super-hard layer connected to the substrate, the end surface of the super-hard layer is an end surface which is formed by a main cutting part and an auxiliary cutting part and provided with at least two camber surfaces, the auxiliary cutting part is located on the periphery of the main cutting part, and the outer end of the main cutting part and the outer end of the auxiliary cutting part both extend to the outer edge of the end surface of the super-hardlayer. According to the multi-surface arc-shaped diamond compact, rock breaking operation is carried out through the main cutting part, plowing operation and planing operation are carried out throughthe auxiliary cutting part, different operation can be conducted by using the diamond compact, the diamond compact does not need to be replaced in the drilling process, and accordingly, the drilling efficiency is improved. Meanwhile, the different operation is conducted through the main cutting part and the auxiliary cutting part, and the service life of a drill bit can be effectively prolonged.
Description
technical field [0001] The invention relates to the technical field of cutting tools, in particular to a multi-faceted arc-shaped diamond composite sheet. Background technique [0002] The polycrystalline diamond composite sheet is a composite superhard material that is sintered under high temperature and high pressure conditions using single crystal diamond powder and cemented carbide as the support. , has been widely used in the fields of mechanical processing, mining technology and mining exploration. When the polycrystalline diamond compact is applied to hard rock formations, strong abrasive and tough interlayers and other difficult-to-drill formations, the requirements for the performance of the drill bit and the compact are more stringent. [0003] At present, although a variety of heterosexual diamond composite sheets have been developed to address the above problems, such as conical tines, spherical teeth and other special-shaped PCD layers. However, the above-ment...
