Critical Surface Finishing for Hydraulic Systems

In hydraulic systems, performance and reliability are dictated by flawless internal cleanliness. Microscopic burrs, debris, or irregular surfaces within components can cause spool valve sticking, seal damage, and catastrophic system failure. Achieving perfect bore geometry and contaminant-free fluid paths is not a suggestion—it is the fundamental requirement for maintaining pressure, flow, and control in everything from heavy machinery to precision industrial equipment.

Manifolds & Valve Blocks: Zero-Tolerance for Cross-Hole Burrs
The heart of any hydraulic system, manifolds contain intricate networks of intersecting drilled passages. The burrs formed where these holes meet are a severe hazard. If dislodged, they become destructive debris. Effective cross-hole deburring is therefore a mandatory process. Specialized tools must completely remove these burrs without altering the precise geometry of the port intersections, ensuring smooth, unobstructed fluid flow and preventing valve malfunction.

Cylinder Tubes & Actuator Barrels: The Foundation of Seal Integrity
Hydraulic and pneumatic cylinders rely on a perfect seal between the piston and the tube wall. The internal bore surface must have a consistent cross-hatch pattern and precise surface finish (Ra) to retain lubrication and allow seals to function properly without wear. Precision honing is the definitive process for achieving this, removing microscopic imperfections, straightening the bore, and creating the ideal surface texture for maximum seal life and leak-free operation.

Pipes, Tubing, and Complex Galleries: Ensuring Contaminant-Free Paths
Before assembly, all fluid-carrying conduits require thorough internal cleaning to eliminate machining chips, oxides, and particulate. Aggressive yet controlled internal brushing is used for this purpose. Effective tools must navigate long passages and varying diameters to scrub walls clean, preparing the system for its critical first fill with clean fluid, free of initiatory contaminants.

At Longguang, we engineer solutions for these exacting hydraulic challenges. Our tools are designed to meet the precision and reliability demands that hydraulic system manufacturers require.
