Zhengzhou Diamond Engine Valve Guide Hole Processing PCD Reamer
Achieves over 8 times the lifespan compared to carbide reamers! This is a PCD reamer for machining automotive engine valve guide holes!
Zhengzhou Diamond is the largest manufacturer of PCD and CBN tools in China, supplying special tools for engine and automotive parts processing to 90% of automotive manufacturers in China (foreign, Japanese, and local). While it can manufacture extremely high-precision tools, it has achieved a cost reduction of 30% compared to Japanese manufacturers, and its products are adopted by major automotive manufacturers, construction machinery manufacturers, and heavy industry manufacturers in Japan. This product is a PCD reamer for machining automotive engine valve guide holes, achieving more than eight times the lifespan compared to the carbide reamers previously used. The key feature is the ability to cut powder metallurgy sintered materials with PCD. - The main body is made of carbide, providing high rigidity, with an oil hole of φ1. - The cutting edge uses PCD with a particle size of 10μ to 25μ. - Many special sizes are available, including: Reamer diameters D1 = φ5.0, φ5.5, φ6.0, with a total length L = 240 to 280. We are confident that our lifespan and precision are on par with Japanese manufacturers, and we have case studies to back this up, so please try it out starting with a test.
