CHENOU Precision Technology was established in the year 2006, mainly producing diamond wire drawing dies. With the demand of the market, we expanded our offerings to include OEM ceramic inkjet nozzles, ruby dispensing nozzles, high-pressure diamond spray nozzles, ruby balls, and other micro orifice parts. Today, we are capable of producing a wide range of micron orifice components for super hard materials.

• Our advantages

  We specialize in precision hole machining of super hard materials components, including diamond, ruby, sapphire, PCD, ceramic, and tungsten carbide. Our precision can reach +-0.005mm. Our rigorous quality control process, from material selection to precise measurement systems accurate to 0.001mm, has earned us the trust of customers. As a result, our business has expanded from local to global, serving clients in the USA, Canada, Europe, South America, and Southeast Asia.

• Application of our products

   Our products have wide applications in industries such as medical, aerospace, and EDM that require high precision. Our current main advantages are micro-hole drilling, grinding, and polishing on hard materials. We manufacture components with hole diameters ranging from 0.03mm to 10.0mm. We excel in micro-hole machining with sizes ranging from 0.03mm to 1.0mm. We continuously research new hard materials and technologies and invest in new machines to add more value for our customers. Additionally, we offer OEM services for high-precision components made from hard materials.
