Precision CNC Machining for Hydraulic Equipment
Hydraulic components demand exact bore fits, leak-free port connections, and materials that handle high pressures. A manifold crosshole that's misaligned by 0.003 inches can restrict flow and cause system failure. We machine 4140 steel, ductile iron, 316 stainless, and aluminum to tolerances as tight as ±0.0005 inches. Every order ships with CMM inspection reports, material certs, and bore finish verification.
High-Pressure Materials
We source and machine 4140/4340 steel, ductile iron, 316 stainless, and 7075 aluminum — all with full material certs and heat lot traceability for pressure-rated applications.
Precision Bore Work
We hold ±0.001" on bore diameters and finish hydraulic passages to 16 Ra or better. Crosshole intersections are deburred and inspected for flow path integrity.
Full Documentation
Dimensional inspection reports, material certs, bore finish measurements — whatever your quality system requires for hydraulic component acceptance.

316SS & 4140 steelServing the US Hydraulic Equipment Industry
The US hydraulic equipment market powers everything from construction excavators to industrial presses to mobile lifting systems. Every hydraulic circuit depends on precisely machined manifolds, cylinders, and valves that perform at thousands of PSI.
OEMs and hydraulic system integrators rely on machine shops that can drill deep crossholes, hold tight bore tolerances in hardened steel, and deburr internal passages for clean flow paths.
Whether you're building custom hydraulic power units or manufacturing standard cylinder assemblies, we want to be your machining partner. Upload your file for instant AI pricing — we ship anywhere in the US.
