Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a novel guide rail protective cover for numerical control machine tools. Background Art

[0002] CNC machine tools (digital control machine tools) are automated machine tools equipped with a program control system. CNC machine tools integrate mechanical, automation, computer, microelectronics and other technologies to solve the processing problems of complex, precise and small batch parts.

[0003] CNC machine tools have the characteristics of strong adaptability to processing objects, high processing precision, stable processing quality, high productivity, high reliability, and improved working conditions. CNC machine tools can move and process parts according to the programmed program, while the existing CNC machine tool guide rail protective covers are generally foldable, which causes friction when the foldable guide rail protective covers move. Under long-term work, the wear between multiple protective covers is more serious, thereby reducing the service life of the protective covers. For this reason, we propose a new type of CNC machine tool guide rail protective cover to solve the above problems. Utility Model Content
