Abstract (en)

A method of sawing an object (700) includes providing a wire saw apparatus (2), which includes tank (20) defining a receiving space (21) having an opening (211) and receiving a cutting liquid (200), an ultrasonic vibrator (3) disposed in the tank (20), and multiple sawing wires (4) located above the opening (211) and spaced apart from the cutting liquid (200) . The method further includes driving the ultrasonic vibrator (3), reciprocating the sawing wires (4), and moving the object (700) toward the sawing wires (4), so that the object (700) is cut by the sawing wires (4) to form multiple cut grooves (400), and subsequently a part of the object (700) is immerged into the cutting liquid (200), each of the cut grooves (400) having a width (W) allowing the cutting liquid (200) to enter the cut grooves (400) by capillary action.
