Horizontal wire cutting method

The invention discloses a horizontal type wire cutting method which comprises the following steps: 1) putting a crystal bar into horizontal type wire cutting equipment, fixing one end of the crystal bar by adopting a tail end supporting mechanism, and then fixing the rest part of the crystal bar at intervals in a segmented manner by adopting at least one liftable supporting pile according to requirements; (2) presetting linear cutting parameters through the integrated control box; (3) through external power and transmission of the gear and rack transmission mechanism, the linear cutting structure is driven to move to the to-be-cut position of the crystal bar along the gear and rack transmission mechanism; and (4) the linear cutting structure and the winding tensioning mechanism are started to conduct linear cutting on the crystal bar. According to the horizontal type wire cutting method, the special horizontal type wire cutting equipment is adopted, so that the horizontal type wire cutting method is simple in
