Cutting Tools for Hydraulics & Fluid Power
The cavity-tool specialists for hydraulic manifolds.
Cartridge cavities, ports and custom manifold form tools — JIAYI grinds cavity tools for Sun Hydraulics-type, HydraForce-type, Parker Hannifin-type, Bosch Rexroth-type, Eaton Vickers-type and Danfoss-type cavities, plus SAE, ISO and BSPP port tools.
The challenge
A manifold block is a maze of precision cavities where every sealing surface has to be right the first time. Cartridge cavities have stepped profiles with tight diameter relationships; a form error becomes a leak path. Standard tools cover standard cavities — the moment the print deviates, you need a custom form tool ground to that exact cavity.

Have a cavity print that no catalog tool fits?
Send us the drawing. If it's a standard cavity-type, we'll match it. If not, we'll grind it.
