Different types of square cutting machines (such as square cutting machines based on mechanical structure and single crystal silicon square cutting machines) are different in specific working principles and structures. For square cutting machines based on mechanical structure: the steel wire forms a cross-wire net loop through the wire-reeling and wire-releasing wheels and four guide wheels. The mortar sprayed from the mortar nozzle covers the wire net. The workbench with the silicon block installed presses down into the wire net running at high speed with the mortar, thereby realizing mortar wire cutting.
