Zhengzhou Diamond is the largest manufacturer of PCD and CBN tools in China, supplying special tools to 90% of automotive manufacturers in China (foreign, Japanese, and local). While it can manufacture extremely high-precision tools, it has achieved a 30% cost reduction compared to Japanese manufacturers, and its products are adopted by major automotive manufacturers, construction machinery manufacturers, and heavy industry manufacturers in Japan. Zhengzhou Diamond also has a wealth of experience with PCD tools for CFRP processing, being the only Chinese tool manufacturer adopted for CFRP processing for Boeing, as well as for Chinese aircraft manufacturers. Zhengzhou Diamond's PCD special reamers and drills exhibit characteristics such as high hardness, high thermal conductivity, and low friction coefficient against difficult-to-cut CFRP, effectively suppressing burr generation and receiving high praise. We are confident that our tool life and precision are on par with Japanese manufacturers, and we have case studies to prove it, so please start by trying a test.
