Experience zero-defect fluid power components engineered for high-pressure applications and long-term operational dependability across demanding industrial environments.
Machining services delivers top-tier services designed for the industrial machinery sector, producing high-performance components that ensure optimal machine functionality and reliability. From heavy-duty gears and precision shafts to custom housings and brackets, we specialize in parts that withstand the most demanding environments. With our advanced machining capabilities, we ensure tight tolerances and superior material selection, delivering components that meet the rigorous standards of industrial machinery manufacturing.
Hydraulic and pneumatic components form the critical fluid power infrastructure that drives modern industrial machinery operations. These precision-engineered parts must maintain perfect sealing integrity under extreme pressures, resist contamination, and deliver consistent performance across millions of operational cycles. Even microscopic surface imperfections or dimensional deviations can lead to catastrophic leaks, pressure loss, and complete system shutdown.
Yicen Precision excels in hydraulic and pneumatic components CNC machining using advanced 5-axis milling centers and precision boring equipment. We manufacture complex hydraulic manifolds, pneumatic cylinder barrels, valve bodies, actuator housings, and custom fluid control assemblies from aerospace-grade aluminum alloys, stainless steel, and brass materials. Our ISO 9001 and AS9100 certified manufacturing processes ensure every hydraulic and pneumatic component achieves tolerances of ±0.0003″ on critical sealing surfaces. With advanced deep-hole drilling capabilities and comprehensive pressure testing protocols, we deliver fluid power components that guarantee leak-free performance and maximum system efficiency.

What surface finishes can you achieve for pneumatic cylinder bores?
For pneumatic cylinder bores, we routinely achieve 8-16 Ra surface finishes using precision boring and honing operations. For applications requiring superior seal life and minimal friction, we can deliver 4-8 Ra finishes with honing. All cylinder bores are inspected using surface profilometry to verify finish specifications and ensure consistent quality across production runs. We also offer hard chrome plating and electroless nickel plating for enhanced wear resistance.
Can you machine custom port configurations and thread types for hydraulic fittings?
Absolutely. We machine all standard hydraulic port threads including NPT, BSPP, BSPT, SAE straight thread (ORB), JIC 37° flare, and metric threads per ISO 6149 standards. Our 5-axis capabilities enable custom port orientations at any angle with precise depth control. We also accommodate proprietary fitting designs and can provide thread inspection certifications using calibrated thread gauges and optical measurement systems.
How do you ensure internal passages are properly deburred in manifold blocks?
We employ a multi-stage deburring process including specialized rotary deburring tools for accessible intersections, abrasive flow machining for complex internal passages, and electrochemical deburring for critical high-pressure ports. Our quality control includes borescope inspection of internal passages and cleanliness verification per ISO 4406 standards to ensure no residual contamination that could damage downstream components.
What is the maximum pressure rating for hydraulic components you manufacture?
Yicen Precision regularly produces hydraulic components rated for working pressures up to 5,000 PSI, with capability for specialized applications up to 10,000 PSI. All components undergo hydrostatic pressure testing at 1.5x rated working pressure to verify integrity. We provide pressure test certifications and can accommodate custom testing protocols based on your specific application requirements.
