Hydraulic Component Machining

Zero-Leak Tolerances. Every Shipment.

In hydraulics, a part that’s a few tenths out of tolerance doesn’t just fail your quality check — it fails in the field. MicroPrecision holds the diameters, roundness, and surface finish that keep pressure systems sealed and operating as designed.

The Hydraulics Problems We Were Built to Solve

  • The Issue: “We’re getting field leaks traced back to spool dimensions”

    The Fix: 
    We Hold What Others Drift

    Spool-to-bore clearances are routinely in the .0002″–.0005″ range. We verify roundness, cylindricity, and surface finish on every critical dimension using our Federal Mahr roundness checker and Zeiss CMMs.

     

  • The Issue: “Our current shop can’t machine the harder alloys”

    The Fix: We Machine the Materials Others No-Quote.

     

    Hardened steels, stainless, brass, and high-strength aluminum — our tooling is dialed in and our processes are proven. If you’re getting no-quotes elsewhere, send it to us.

     

  • The Issue: “Lot-to-lot consistency keeps slipping”

    The Fix: SPC and Vision Systems on Every Run.

     

    Real-time statistical process control catches tool wear and dimensional drift during the run — not after the part ships.

Hydraulic Components We Produce

  • Spools and valve stems — tight-clearance cylindrical components with critical surface finish

  • Valve bodies and housings — ported and cross-drilled in-house

  • Pistons and plungers — turned, ground-prep, and documented

  • Port fittings and adapters — machined and assembled

  • Manifold components — milled, tapped, and deburred

Materials: Carbon steel · 4140/4340 alloy steel · 303/316 stainless · C36000 brass · 6061 aluminum · Inconel for high-pressure applications
