The double helix structure of DNA stores the genes that are in charge of all the information of life, and the genes are reflected in human beings as blood type, appearance, health and so on, while in the enterprise, it is the tone set at the beginning of its establishment.

For Zhengzuan, the core gene that grows deep in the enterprise is the attitude of precision and sincerity, and the persistent craftsmanship. In practice, it is to craft each product, to do a good job of service, and to create and deliver value that exceeds customer expectations. The products of Zhengzuan are the windows that silently show the original heart of the company and the carrier that carries the genes of the company, and the metallic luster of the tools reflects the craftsmanship of the company.

From one generation to three generations, Zhengzuan PCD countersinks have undergone two product evolutions, with continuous quality breakthroughs. In the process of refinement and progress, Zhengzuan has been sharpening more mature products and refining more perfect technical services without distractions.

  • The first generation of HSS countersink drills, due to the characteristics of the steel itself, HSS countersink drills have poor wear resistance. 
  • The second generation of carbide countersink drills, compared with HSS, the cutting speed of carbide made under high temperature and pressure is 4-7 times higher than that of HSS, but there are shortcomings of brittleness, low impact and vibration resistance.
  • The third generation of PCD countersink drill, using super hard material PCD as raw material, is suitable for CFRP and fiber metal plate layer processing, which greatly improves the durability of the cutting edge and extends the life of the hole guide column by 80% compared with the previous generation. In addition to the excellent quality of the product itself, it also has excellent surface roughness index retention and precision grade, and can meet the full specifications of metric and US standard tools for 100° and 130° countersinking angles.

The evolution of three generations of products, behind the heart and wisdom of Zhengzuan, reflects the attitude of Zhengzuan for excellence. The more mature PCD countersink is another fist product of Zhengzuan in the field of aerospace manufacturing, which has a remarkable performance against the imported countersinks of the same specification.
