Description

Technical Field

[0001] The utility model relates to the technical field of machine tool equipment, in particular to a machine tool protective door structure. Background Art

[0002] A machine tool is a machine used for processing metal or other materials. It can process blanks or workpieces to achieve the desired geometry, dimensional accuracy, and surface quality. A machine tool is a machine that manufactures machines and is also known as an industrial machine tool, machine tool, or machine tool. In modern manufacturing, machine tools play a vital role and are fundamental to industrial automation and intelligent manufacturing. CNC machine tools are conventional machining equipment and are automated machines equipped with a program control system. This control system logically processes programs specified by control codes or other symbolic instructions, decodes them, and represents them as coded numbers, which are then input into the CNC device via an information carrier. After computational processing, the CNC device issues various control signals, controlling the machine tool's movements and automatically producing parts to the shape and size specified in the drawings.

[0003] CNC machine tools include protective doors to prevent foreign objects or people from entering the processing space during processing; the protective doors of general CNC machine tools are slide-type, and when processing workpieces, some metal debris will splash into the slide, affecting the smoothness of the protective door opening and closing. For this reason, this case was born. Utility Model Content
