Process 

CNC machining uses computer programs to control machine tool motion, enabling precise control of tool paths and cutting parameters. This allows for micron-level machining accuracy and the ability to produce complex shapes in a single pass, preventing microcracks in molybdenum products during machining.

① Select high-purity molybdenum plates (≥99.95%) and remove the oxide layer through hydrogen reduction or chemical cleaning.

② Remove most excess material through turning and milling, controlling cutting parameters to avoid material cracking.

③ Final dimension machining is performed using CNC machines or high-precision grinders, combined with water-jet laser cutting and drilling.

④ Surface cleaning and grinding, and, if necessary, coating or anodizing, to enhance wear resistance and creep resistance.

⑤ Rigorous quality inspections are performed, including dimensional accuracy, surface quality, mechanical properties, and non-destructive testing.
