Abstract
The present invention provides a bandsaw cutting apparatus including an actuator configured to move static pressure pads forward and backward in a rotating direction of a blade, and a controller configured to control a movement distance and a movement speed of the static pressure pads to be moved by the actuator, wherein the ingot is cut by feeding the blade relatively downward toward and below the ingot while a rotating blade is guided with static pressure pads, and the movement of the static pressure pads is controlled with the controller. The apparatus can stably suppress a displacement of the blade during cutting, thereby cutting the ingot into blocks or sample wafers for crystal quality evaluation stably with good quality cut surface at a higher cutting rate and extending the lifetime of the blade.
