Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a protection mechanism for numerical control machine tools. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool 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 process the parts according to the shape and size required by the drawing. The basic components of CNC machine tools include processing program carrier, CNC device, servo drive device, machine tool body and other auxiliary devices.

[0003] Existing CNC machine tools always generate chips during the processing process. The flying chips can easily damage the machine and the processed parts, posing a safety hazard to the operator. Therefore, existing CNC machine tools are shielded by protective doors, and glass protective doors are used to facilitate observation of the processing status. However, during processing, in order to cool the workpiece and the tool, the existing machine tools spray coolant while processing. The coolant will also be splashed out by the rapidly rotating tool and sprinkled on the protective door, causing the view inside the glass door to become blurred, making it inconvenient to observe.
