High-Precision CNC Machined Hydraulic Valve Blocks for Mining Industry
Mining equipment operates under extreme working conditions: high system pressure, heavy vibration, dusty air and continuous long-hour operation. Ordinary hydraulic valve blocks often suffer oil leakage, valve sticking and early wear. For this reason, mining machinery requires specially reinforced hydraulic valve manifolds made with strict CNC precision.
Processing Requirements for Mining Hydraulic Valve Blocks
- Strict dimensional tolerance
We control hole position accuracy within ±0.02mm. The mating holes for valve spools can reach 0.002mm precision to avoid internal leakage under long-term high pressure.
- Complete deburring of inner flow channels
Cross-hole burrs will pollute hydraulic oil and cause valve failure. We use ultrasonic and manual deburring to ensure all oil passages are clean and smooth.
- Stable material selection
We adopt high-strength carbon steel and alloy steel for mining valve blocks. After stress relief treatment, the workpiece will not deform after long-term pressure cycles.
- Strict pressure testing
Every finished valve block will pass high-pressure leakage testing to meet underground mining safety standards.
Our Advantages in Manufacturing Mining Valve Manifolds
Our workshop is equipped with multi-axis CNC machining centers and deep hole drilling machines. We complete rough milling, finish machining, deep hole processing and surface grinding in-house without outsourcing.
We have rich experience cooperating with global mining equipment suppliers from Turkey, Russia and Europe. We can customize integrated valve blocks according to customers’ hydraulic circuit drawings, reducing pipeline connections and improving system stability.
Whether you need single-piece prototypes or bulk OEM orders of mining hydraulic valve components, we can provide CMM inspection reports and pressure test certificates to guarantee consistent batch quality.
