In the demanding world of fluid power systems, component failure is not an option. Hydraulic and pneumatic components form the backbone of industries from heavy machinery and aerospace to automation and manufacturing. The performance, reliability, and longevity of these systems hinge on the precision and integrity of every single part—from valve bodies and manifolds to piston rods and cylinder blocks. This is where advanced CNC machining transitions from a manufacturing choice to a critical necessity.

The unique challenges of hydraulic and pneumatic components require a specialized machining approach. These parts must withstand extreme pressures, resist corrosion, and maintain leakproof seals over millions of cycles. Achieving the necessary surface finishes, often to Ra 0.4μm or better, and holding tight geometric tolerances for bore roundness and flatness are paramount to prevent fluid bypass and ensure efficient operation. Furthermore, materials like stainless steel, aluminum alloys, and engineered plastics are commonly used for their strength and durability, demanding precise machining strategies to avoid work hardening or distortion.

Our company provides a comprehensive onestop CNC machining solution tailored specifically for this sector. We leverage stateoftheart multiaxis CNC centers to produce complex internal porting, intricate crossdrilled holes, and flawless sealing surfaces in a single setup, ensuring perfect alignment and reducing potential leak paths. Our expertise extends to secondary processes critical for fluid power components, including precision honing for cylinder bores, specialized surface treatments for wear resistance, and rigorous 100% pressure testing. Every component is validated against the strictest specifications.
