  • Machining Conditions And Stability Of Titanium Alloy Parts

    Titanium alloy parts have the characteristics of low density and good corrosion resistance, so they have also become ideal structural materials for aerospace engineering. However, there are many factors that affect its machinability at the same time. This is because the metallurgical properties and material properties of titanium alloys may have a serious impact on the cutting effect and the material itself.

  • 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.
