Method an apparatus for separating slices from a brittle workpiece using a wire saw where the cutter is cleaned during the cutting process by ultrasound

摘要

The cutting method causes relative movement at a predetermined speed between the work piece and a cutting wheel of a multi wire saw. The cutting wheel is cleaned during the cutting process in a cleaning bath which is charged by an ultrasonic or megasonic stimulator. The frequency and/or power of the stimulation can be varied according to the surface area of the work piece or the speed of cutting.
