CNC Machining Process

  • Material Preparation: Suitable metal raw materials such as stainless steel or alloy steel are selected and pre-treated, e.g., annealing or quenching, to enhance machinability.
  • Rough Machining: Utilizing CNC machining centers to remove excess material and form the basic contour.
  • Finishing: Employing high-precision CNC machining techniques to finely polish the blades and hub, ensuring streamlined blade design and overall symmetry.
  • Inspection and Correction: Precise measurements using coordinate measuring machines and other inspection equipment are conducted to rectify any non-conforming areas until meeting design requirements.


The turbine compressor impeller manufactured through CNC machining meets design requirements in terms of appearance quality, dimensional accuracy, and surface smoothness. In practical applications, it demonstrates excellent compression performance and stability, effectively enhancing the overall performance and lifespan of compressors. Moreover, adopting high-precision CNC machining technology significantly improves production efficiency and product quality.
