Industry Context & Processing Challenges: Flight control hydraulic valve bodies and servo actuators consist of high-strength stainless steel or aluminum blocks with precision spool bores requiring high-concentricity hole drilling and reaming.
Technical Requirements: Bore circularity and straightness within ≤0.002 mm, and surface finish Ra≤0.1 μm.
ZWH Tooling Solutions & Value: ZWH solid carbide step drills and PCD fine-boring bars execute coaxial multi-step hole finishing in a single pass, ensuring leak-free hydraulic performance under high pressure.
