Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a vacuum suction cup of a numerical control machine tool. Background Art

[0002] CNC machine tools are digitally controlled machine tools, which are automated machine tools equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool, and automatically processes parts according to the shape and size required by the drawings. CNC machine tools used for plate or glass processing mostly use vacuum suction cups for adsorption and positioning. Current CNC machine tools only rely on vacuum suction cups to position plates or glass. If the plate or glass tilts, it is easy to cause damage to the plate or glass. Utility Model Content
