[0002] In order to improve safety, existing CNC machine tools are generally equipped with protective covers. The protective cover of CNC machine tools is used to protect the cover body of the CNC machine tools. It separates the machine tools from the external environment through physical isolation, preventing damage to the machine tools by splashes such as iron chips, debris, and coolant. At the same time, it also reduces the impact of the external environment on the internal temperature, humidity and other parameters of the machine tools. The existing protective cover is generally slidably connected to the front of the machine tool. The protective cover is generally composed of a cover body, a connecting slider and an observation window.
