What Makes Manifold &
Cavity Machining Different

Deep-Hole Drilling & Cross-Gallery Intersections
Internal galleries in manifold blocks require deep-hole drilling with L/D up to 30:1, precisely intersecting crossing galleries within 0.1 mm at depth. Gun-drilling for long straight bores; BTA drilling for larger diameters. Ball-plug sealing and cross-hole deburring performed before any pressure test.
L/D 30:1 Gun-drill / BTA Cross-hole deburr Ball-plug seal
📐
Sealing Face Flatness & Surface Finish
O-ring face seal and metal-to-metal sealing surfaces require flatness ±0.003–0.005 mm and surface finish Ra ≤0.8 μm. Face seal surfaces finish-milled then ground or lapped to specification. Flatness verified by CMM and surface roughness by contact profilometer on every sealing face before delivery.

🔬
Precision Bore Finishing for Valve & Spool Bores
Spool bores for directional control and proportional valves held to H6 tolerance (typically ±0.008 mm on a 20 mm bore) with roundness ≤0.003 mm and cylindricity ≤0.005 mm. Achieved by reaming, precision boring, and honing sequence. Honing removes lobing and tool marks, leaving a cross-hatch pattern that retains spool lubricant.

Why Fluid System Engineers Specify Our Manifold Parts

Leak
Every Part Leak Tested — Certificate Included
No hydraulic manifold, vacuum component, or fluid block ships without a documented leak test. Hydraulic pressure test to 1.5× working pressure; helium mass spectrometer for vacuum and semiconductor parts. The test certificate ships with the part — not available on request, included as standard.
Deep
Deep-Hole Drilling & Cross-Gallery Accuracy
Long internal galleries with L/D up to 30:1 and intersecting cross-galleries — the two hardest features in manifold machining — are our standard capability. Gun-drilling, BTA, and coordinated multi-axis intersection alignment so your manifold block works exactly as designed.
EP
Electropolished Semiconductor-Grade Surfaces
Gas distribution plates and vacuum components electropolished to Ra ≤0.25 μm and helium leak tested to 10⁻⁹ mbar·l/s in-house. Clean-room packaging under nitrogen purge. The full semiconductor process gas supply chain in one supplier.
Bore
H6 Spool Bores with Honing Cross-Hatch
Valve body spool bores held to H6 tolerance with roundness ≤0.003 mm and cross-hatch hone finish for oil retention. The detail that separates a functioning directional control valve from one that leaks past the spool — we deliver it as standard on every valve body order.
