New Development of PCD Cutter Technology

In order to meet the requirements for improving the performance of PCD cutter and having a larger market share in the fierce competition, PCD cutter manufacturers still continue to improve and increase the PCD cutter technology.

By optimizing the PCD sintering process to force the generated commensal between diamond grains to increase, it can improve the wear resistance of the coarse particle PCD cutter. The abrasion resistance of CTH025 trademark brand increases by 25% ~ 30% compared with the same type of coarse particle PCD, and this trademark is designed for cutting aluminum metal matrix composites with high wear resistance. A new type called "multimodal” PCD is also launched, which is developed for the mining industry. Its characteristic is that every piece of blade materials are distributed in different particle size of diamond particles.

A few years ago, the United States launched fine a kind of PCD trademark called DA2200, whose PCD cutter can process into the high surface finish of workpieces that has high strength almost as cemented carbide. In order to deal with the pressure of the price-off of PCD cutter lately, they developed DA2200 brand cutter instead of more expensive prototype cutter. The adoption of advanced PCD sintering process can help produce DA2200 composite films whose PCD diamond layer thickness is only about a third of the standard thickness.

Recently, the development and application of multifunctional rotary cutter that is made of PCD blade has increased. This cutter can go through drilling, reaming, chamfering, finishing, and other machining process at a time. If used in automobile manufacturing industry, it can effectively reduce the processing cost. For example, the multi-function PCD cutter can process as many as thousands of pieces of automobile gearbox parts before regrinding. They also developed a kind of super speed PCD milling cutter without regrinding.

With the constant improvement of the cutting performance and the price-off of PCD cutter, PCD cutter has attracted a great number of users, which will forcefully promote the popularity and application of PCD cutter and make PCD cutter technology develop more quickly.
