Preguntas más frecuentes
El vidrio de cuarzo es un material duro y quebradizo con excelentes propiedades físicas y químicas, dureza mecánica extremadamente alta, buen aislamiento eléctrico, resistencia a altas temperaturas y a la corrosión, rendimiento de retardo bajo y estable, buena transmitancia luminosa, etc. Se utiliza ampliamente en semiconductores, óptica, electricidad, química, aeroespacial, automoción y otros campos. Los materiales duros y quebradizos son difíciles de procesar, y muchos campos necesitan urgentemente procesos de corte con un pequeño colapso del borde, menos pérdida de material, baja rugosidad de la sección transversal y un amplio rango de grosor de corte. El método de corte tradicional del vidrio de cuarzo es el corte mecánico, es decir, el corte por disco. Los métodos de corte no tradicionales incluyen el corte por chorro de agua, el corte por hilo de descarga electroquímica, el corte por láser continuo, etc. El corte mecánico tiene un bajo coste, pero el contacto entre la rueda y el material causa un gran desgaste de la herramienta, y el material es fácilmente contaminado por la herramienta. El vidrio de cuarzo es propenso al colapso de los bordes, las microfisuras y la tensión residual, lo que afecta a la resistencia y el rendimiento del material. Es difícil conseguir un corte curvo y requiere un tratamiento posterior, como esmerilado y pulido. El corte por láser no entra en contacto directo con el material, no tiene tensión de contacto y puede realizar cortes curvos complejos. El láser de picosegundos tiene las ventajas de un diámetro de punto pequeño, alta precisión, tiempo de acción corto con el material y área de acción pequeña, y es adecuado para el procesamiento de materiales duros y quebradizos.
