  • Similarities and differences between powder metallurgy and CNC machining

    It is found from the finished products that the shapes of products made by NC machining and powder metallurgy are similar, but it is obvious that the price of NC machining is more expensive than powder metallurgy, so why not use powder metallurgy to make products? It seems that there is still a difference between powder metallurgy and CNC machining.
