Sierra de alambre de diamante anular para cortar cerámica

Actualmente, Los procesos de aserrado y corte de materiales duros y quebradizos están plagados de problemas como la baja eficiencia de procesamiento, Bajo rendimiento de material, Mala calidad e integridad de la superficie, Altos costos de herramientas, y la contaminación ambiental. Al usar sierras circulares para cortar materiales como piedra y cerámica, Las hojas de sierra deben poseer un cierto grosor para garantizar la rigidez. Esto da como resultado cortes amplios, Bajo rendimiento de material, y una contaminación significativa. Adicionalmente, Las sierras circulares no pueden realizar el mecanizado de superficies moldeadas, lo que conduce a una calidad superficial inferior al cortar materiales cerámicos. En la industria de semiconductores, el uso de métodos de corte con alambre abrasivo libre para procesar cristales de silicio resulta en una contaminación ambiental y superficial significativa por lechada de abrasivo de diamante, aumentando así los costos asociados con el procesamiento posterior y el tratamiento de residuos.

Sierra de hilo diamantado es un método de corte de materiales duros y frágiles que ha experimentado un rápido desarrollo en la última década, involucrando principalmente el uso de tipos abrasivos libres y abrasivos unidos. Based on the wire saw’s motion and machine structure, it can also be classified as reciprocating and unidirectional wire saws. Actualmente, reciprocating multi-wire saws using free abrasives dominate in the semiconductor and optoelectronic industries. To address issues such as low cutting speeds and abrasive slurry contamination, the diamond unidirectional wire saw utilizing bonded abrasives has been proposed. This type of wire saw features a simple structure, enables high-speed wire movement, and allows for shaping operations, thus holding significant practical importance in advancing equipment for processing hard and brittle materials. The bonded abrasive diamond annular wire saw offers the following advantages:

(1) Ranura estrecha, high material yield. By using high-strength steel wire as the base material, various wire saws with diameters below 1mm can be produced. Companies like Sumitomo Electric Industries and Lid in Japan have manufactured wire saws with average diameters ranging from 0.175 to 0.180mm using steel wires with diameters of 0.130 and 0.155mm as the base material, achieving an actual kerf loss of 0.19mm in sodium glass cutting experiments.

(2) Fast cutting speed, Alta eficiencia. The bonded abrasive annular diamond wire saw features unidirectional movement of the wire saw during the cutting process, with the abrasive grains fixed on the wire saw, eliminating the difficulty of abrasive entry into long and deep kerfs. Compared to reciprocating structures and wire saws using free abrasives, it is easier to achieve higher cutting speeds, resulting in high processing efficiency.

(3) Smooth cutting process, good slice surface quality. During the cutting process with a diamond wire saw, the cutting force is small and gentle, without the unique grooves generated on the workpiece surface due to reciprocating wire saw movement.

(4) Minimal environmental pollution. Bonded abrasive diamond wire saws typically use water as the standard coolant, and dry cutting methods can even be employed at lower wire speeds. This results in low or no need for wastewater treatment due to the use of bonded abrasives.

En conclusión, in today’s increasingly widespread applications in non-conductive materials, semiconductor materials, y materiales compuestos, the bonded abrasive diamond wire saw demonstrates unique advantages in cutting hard and brittle materials. Sin embargo, current research and applications are insufficient, particularly in areas such as wire saw manufacturing technology, cutting processes and mechanisms, modos y mecanismos de falla de sierras de alambre diamantado, y tecnologías de control de postura y movimiento de la sierra de alambre en corte de conformado de precisión. Existen muchas lagunas significativas que justifican una exploración adicional. Este estudio tiene como objetivo explorar la tecnología de corte con sierra de alambre diamantado electrochapada, comprender profundamente sus mecanismos de corte, y promover el procesamiento preciso y eficiente de materiales duros y frágiles, lo cual tiene una importancia significativa.
Las sierras anulares se adaptan a ciertas formas; para trabajos planos de precisión la referencia es corte de precisión de alúmina.

Preguntas Frecuentes

Qué es una sierra de alambre diamantado anular?

Es una sierra de alambre con abrasivo unido en la que los granos de diamante están fijados en un lazo de alambre que se mueve unidireccionalmente a alta velocidad. La estructura simple permite altas velocidades del alambre y corte conformado de materiales duros, brittle materials such as ceramics — an alternative to reciprocating free-abrasive wire saws.

What advantages does a bonded-abrasive wire saw have over free-abrasive sawing?

Because the diamond grains are fixed on the wire, there is no abrasive slurry that must enter long, deep kerfs, so higher cutting speeds are achievable. It also produces a narrow kerf with high material yield, a smooth cut surface without reciprocating grooves, and far less contamination.

¿Qué tan estrecho es el corte de una sierra de hilo de diamante??

Manufacturers such as Sumitomo Electric Industries and Lid in Japan have produced wire saws averaging 0.175-0.180 mm in diameter on steel cores of 0.130-0.155 milímetro, achieving an actual kerf loss of about 0.19 mm in sodium glass cutting experiments.

Is diamond wire sawing environmentally friendly?

Relatively yes. Bonded-abrasive diamond wire saws typically use plain water as coolant, and dry cutting is even possible at lower wire speeds. With no free-abrasive slurry, there is little or no wastewater treatment required — a major contrast with slurry-based silicon wafering.
