Description

Technical Field

[0002] With the development of modernization, an automated machine tool and a CNC machine tool equipped with a program control system have appeared in people's sight. It can make the machine tool move and process parts according to the pre-programmed program. In order to avoid the metal debris and waste liquid splashing generated during the spindle processing from entering the tool magazine, a tool magazine cover is set between the tool magazine and the spindle for isolation.

[0003] When the existing CNC machine tool tool magazine guard is in use, the door on the guard is usually opened when changing the tool to allow the tool holder to pass through for tool changing. When the tool is processing, it usually generates high heat, causing its temperature to rise, and coolant is needed to cool it down. When the used tool is replaced, it is sent to the tool magazine and then replaced. Some coolant will remain on the outer surface of the used tool, and the coolant will drip onto the platform of the tool magazine. It needs to be cleaned later, and the staff needs to reach into the inside of the guard to clean it. The cleaning is more troublesome and takes a long time, which affects the use of the tool magazine. Utility Model Content
