Advanced CNC Manufacturing Technology
Comparison with Conventional Separate Welding Machining
| Feature | Traditional Welded Pump Housing | Our Integrated CNC Machined Solution |
|---|---|---|
| Machining Process | Split parts + welding + secondary finishing | Single blank one-time CNC composite milling |
| Dimensional Accuracy | Welding deformation leads to big tolerance fluctuation | Closed-loop CNC control, micron-level precision |
| Structural Leak Risk | Weld seams are prone to coolant leakage | No splicing gaps, integrated flow channel |
| Surface Quality | Weld traces, uneven surface | Consistent smooth milling texture, clean sealing plane |
| Batch Consistency | Welding manual difference affects uniformity | Stable batch production, consistent each piece |
| Service Life | Weld joint fatigue failure under long-term hydraulic pressure | Integral structure, anti-vibration & long service life |
