Description
Product Overview
SINO SEIKO（Sino Qtech Industries Co., Ltd.） is headquartered in Zhengzhou, Henan — China’s largest superhard materials hub. Leveraging our network of certified manufacturers and an advanced PCD blank performance testing laboratory, we deliver reliable, high-performance PCD (Polycrystalline Diamond) cutting tool blanks tailored to your exact specifications.
With over 20 years of industry experience, we have witnessed the growth of the world’s largest PCD manufacturing base and can consistently supply blanks up to the maximum diameter of Φ74mm with exceptional quality and repeatability.
Working Principle
PCD cutting tool blanks are manufactured by sintering fine diamond particles with a metallic catalyst binder under ultra-high pressure (5–6 GPa) and high temperature (1400–1600°C). The resulting structure exhibits extreme hardness (HV ≥ 7000), excellent thermal conductivity, and superior wear resistance — making it ideal for machining non-ferrous materials, composites, and abrasive non-metallics.
