Cutting Tools for Rail Transit
Tooling for rail systems that can't fail.
Brake manifolds, bogie hydraulic blocks, coupler components — JIAYI port tools, drills and threading tools machine rail-transit parts to the quality standards high-speed rail, metro and freight demand.
The challenge
Rail components carry lives, so quality systems are strict and part failure is not an option. Brake control manifolds need leak-tight ports; bogie hydraulic blocks need precise bores; coupler and draft-gear parts need durable threads. Materials range from steels to ductile iron, and every feature has to repeat — across thousands of cars.
