Ask an engineerPrecision concentricity is vital to prevent hydraulic fluid leakage and valve spool sticking. JIAYI SEIKO's port tools are engineered with single-piece solid carbide or high-rigidity steel bodies featuring multi-stage step designs. By combining the pilot diameter, cavity reaming, chamfering, and spot facing into a single-pass operation, we eliminate the cumulative runout errors caused by sequential tool changes, guaranteeing micron-level concentricity between the valve cavity and the thread.
The O-ring sealing area requires a flawless surface finish (often
Ra< 0.8µm or finer) to ensure a high-pressure seal. To achieve this, our port tools utilize specialized burnishing areas or precision-ground wiper flats on the sealing angle inserts/edges. Additionally, ensuring stable high-pressure through-coolant and maintaining an optimized feed rate during the final dwell phase will effectively eliminate micro-chatter, yielding a clean, scratch-free mirror finish.
Yes. JIAYI SEIKO manufactures a comprehensive range of standard port tools fully compliant with global fluid power specifications, including SAE J1926-1 (ISO 11926-1), MS16142, ISO 6149-1, and JIS standards. Furthermore, we regularly supply high-precision replacement porting tools compatible with proprietary industry cavities, such as Sun Hydraulics, Rexroth, and HydraForce designs.
Absolutely. Customized solutions for complex hydraulic manifolds are one of our premier capabilities. Whether you are working with ductile iron (GGG40/50), aluminum blocks, or alloy steels, our technical team can design custom solid carbide or indexable composite port tools tailored precisely to your proprietary CAD prints. We optimize the flute geometry and carbide substrate to ensure maximum tool life for your specific material. Submit your valve cavity blueprint for a custom quotation.
