Precision CNC Machining for Hydraulic Components: Your Trusted Transmission Parts Expert
In the demanding world of hydraulic systems, precision and durability are paramount. From industrial automation to aerospace, the performance of a hydraulic pump, valve, or actuator often hinges on the accuracy of its machined parts. High-pressure environments, complex geometries, and tight assembly tolerances all require a partner with deep expertise in precision CNC machining. This is especially critical for transmission parts like gears, worm gears, and spline shafts, where even the slightest deviation can compromise function and longevity.
As a CNC machining specialist for custom hydraulic parts, we deliver end-to-end manufacturing solutions tailored to your drawings, tolerances, and performance requirements. Whether you need high-strength stainless steel valve blocks, lightweight aluminum pump bodies, or hard-to-machine copper pistons, our team ensures dimensional consistency and performance under pressure.
Challenges in Hydraulic Part Machining — and How We Solve Them
Hydraulic parts often involve:
- Complex internal oil passages
- High-strength materials like hardened steel or titanium
- Tight geometric tolerances for sealing and pressure containment
- Surface finish requirements as low as Ra 0.2μm
- Compatibility with multi-axis assemblies or rotary hydraulic systems
To overcome these, we rely on a combination of:
- 5-axis CNC machining centers for multi-face operations in a single setup
- Swiss-type turning machines for shaft parts like spline shafts and worm gears
- Advanced CAM programming for intricate internal flow channels
- CMM inspection (Coordinate Measuring Machine) and roundness testers for form tolerance validation
- Full traceability under ISO 9001 quality standards
Our team handles prototyping, low-volume production, and OEM mass manufacturing, allowing you to scale at any phase of your product lifecycle.
Common Materials for CNC Hydraulic Parts
Material selection is critical in hydraulic systems due to exposure to pressure, heat, and fluid contact. We work with a wide range of machinable materials, each selected to match application-specific performance:
- Stainless Steel (304/316/17-4PH) – Excellent corrosion resistance, ideal for hydraulic valve blocks, pump shafts, and seal housings.
- Aluminum (6061/7075) – Lightweight and cost-effective, often used in mobile hydraulic systems or aerospace applications.
- Hardened Tool Steel – High wear resistance, suitable for pistons, plungers, and high-load transmission gears.
- Copper and Brass Alloys – Excellent fluid compatibility and thermal conductivity for seal seats and pump inserts.
- Engineering Plastics (PEEK, PTFE) – Used in custom seals, guide rings, or non-metallic bushings.
- Titanium Alloys – Lightweight yet strong, used for aerospace-grade hydraulic parts requiring strength-to-weight performance.
