High-precision CNC machined alumina ceramic components are parts made from aluminum oxide (Al₂O₃) that are shaped and finished using Computer Numerical Control (CNC) machining to achieve extremely tight tolerances, complex geometries, and superior surface finishes. Alumina is chosen for its exceptional hardness, wear resistance, electrical insulation, and thermal stability. CNC machining is necessary because alumina is too hard and brittle to be shaped by traditional methods after it's fired.
