During manufacturing, Si₃N₄ components typically require the machining of precision holes, such as micro-holes, cooling holes, positioning holes, mounting holes, through holes, and airflow holes. Traditional mechanical drilling methods are prone to problems such as edge chipping, cracks, tool wear, and poor consistency. The WHYC laser silicon nitride ceramic laser drilling machine is specifically developed for the precision hole machining of silicon nitride ceramics, providing a stable solution for machining micro-holes, array holes, and precision through holes in 0.2–5 mm silicon nitride components.
The system can also be customized for ceramic cutting, grooving, and contour machining, providing a complete laser processing solution for advanced ceramic manufacturers.
