Introduction: CNC Processing of Advanced Ceramics

CNC machining of ceramics refers to the use of Computer Numerical Control (CNC) machines to perform precision processes such as milling, drilling, and grinding on ceramic materials.The entire machining process is controlled by computer programs, allowing for the precise manufacturing of complex shapes and meeting the micron-level accuracy requirements.

Challenges in Machining Ceramic Materials
Most advanced ceramics possess exceptional hardness and a relatively high level of brittleness, surpassing that of metals.These material properties pose significant challenges in the CNC machining process:

·  The machining of ceramic components typically involves grinding, which is a time-consuming process. Due to the brittleness of ceramic materials, CNC machining of alumina ceramics is prone to chipping. Therefore, CNC equipment used for machining technical ceramics generally requires tools made of higher-hardness non-metallic materials.

·  The characteristics of ceramic materials impose higher demands on the experience and expertise of machinists. Skilled machinists need to have a solid understanding of mechanics, perform precise calculations of stress distribution and force transmission for ceramic components prior to CNC machining, and carefully design the feed rate and mechanical balance of the equipment.

·  For high-precision and complex geometries in ceramic components, CNC machining requires not only the proper setting of basic cutting parameters (such as feed rate, spindle speed, and cutting depth) but also the programming of complex tool paths, multiple finishing passes, and tool compensation. Additionally, real-time measurement of machining errors, feedback, and adjustments are necessary to ensure the final machining accuracy.
