aluminum nitride aln machining and grinding

Aluminum Nitride (AlN) Machining and Grinding - San

Aluminum Nitride – AlN, is most often the material of choice due to its relatively excellent thermal conductivity and non-toxic nature. AlN is somewhat more challenging than some other technical ceramic because the fine grained grinding powder adheres to the diamond tooling requiring frequent wheel dressing to allow for efficient stock removal without excessive preassure []

Aluminum Nitride Machining (AlN) Applied

Aluminum Nitride is a versatile material most often used in situations that demand both high thermal conductivity and electrical insulation. This unique ability, combined with its low toxicity, makes AIN ideal for managing rapid heating and removal of heat from other components and systems, such as in heat sinks and spreaders.

High-Efficiency Mirror Grinding of AlN by Ultra

Plane honing machining of aluminum nitride (AlN) was investigated in this study. AlN has advantageous thermal and dielectric characteristics and is in great demand as a semiconductor mounting board or packaging parts material. However, as AlN is a sintered material, the AlN grains readily detach during machining making it difficult to obtain fine surface roughness at high efficiency.
