Abstract
An opening for loading and unloading ingots is formed at the top of a cover, which covers a processing chamber wherein grooved rollers of a wire saw are disposed. The ingots are exchanged from above the cover through the opening. Even if a plurality of wire saws are arranged at short intervals, the adjacent wire saws can exchange the ingots at the same time, Thus, the ingots can be exchanged efficiently.
