CNC Machining Process
Many engineers who have engaged in CNC machining have said that CNC machine tools are one of the greatest inventions in industrial manufacturing, and play an unparalleled role in the production of precision parts for various industries, and they are proud to be engaged in this profession.
They also said that although engaged in this industry requires a lot of professional knowledge, the entry threshold is high, but really understand, you will feel that after this series of processes to produce products is simply art, and the processing process is also a kind of art, multi-axis machine brandishing the blade, drawing a arc as if it is the line of art. Next let's feel the charm of CNC machining.

|
Polishing |
Ranging from Ra 0.8~Ra0.1, polishing processes use an abrasive material to rub the part’s surface to make the shine more less shiny, depending on your requirements. |
