Description

Technical Field

[0001] The utility model relates to the technical field of silicon rod cutting, in particular to a cutting machine with adjustable main shaft spacing. Background Art

[0002] Silicon rods are usually cut using a wire cutting machine, which usually has two spindles for winding wires, thereby performing multiple groups of cuts on the silicon rods.
