CNC Machining and Rare Earth Metals: An Overview
CNC machining, short for Computer Numerical Control machining, is a manufacturing process where pre-programmed computer software dictates the movement of factory tools and machinery. This technology can be used to manipulate a plethora of materials, including but not limited to rare earth metals.
Rare earth metals consist of 17 elements in the periodic table. These are segmented into two categories; the first fifteen lanthanides (lanthanum through lutetium), plus scandium and yttrium. They are termed ‘rare’ not because they’re hard to find – rather due to their scattered distribution across the planet which makes them difficult to extract economically.
The unique properties of these metals such as high heat resistance, electrical conductivity, and magnetic qualities make them integral to numerous industries like technology, renewable energy, defense, and aerospace. Thus, progress in CNC machining techniques plays a crucial role in promoting innovation, efficiency, and sustainability within these key sectors.
