Description

Technical Field

[0001] The invention relates to the technical field of CNC machining centers, and in particular to an ultra-high precision CNC machining center. Background Art

[0002] The machining center is developed from CNC milling machines. The biggest difference between the machining center and CNC milling machines is that the machining center has the ability to automatically exchange machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changing device in one clamping to achieve multiple machining functions. At present, ultra-high precision machining centers will generate constant noise when processing workpieces. Operators and workers often need to wear noise-reducing earplugs to barely work. However, wearing noise-reducing earplugs leads to poor communication between operators and workers, which seriously affects work efficiency. In addition, since factories usually require multiple ultra-high precision machines to run at the same time, noise pollution is more serious, and it is easy to affect the judgment and physical and mental health of operators and workers, and easily leave occupational diseases.

Through the cooperation of the foam board 7, the first sound absorbing board 8 and the second sound absorbing board 9, the difficulty of noise propagation is increased and the transmission of noise is reduced.

[0025] The sound absorbing panel group includes a first sound absorbing panel 11 and a second sound absorbing panel 12. A plurality of first sound absorbing grooves 13 are arranged on a side of the first sound absorbing panel 11 close to the body 1, and a plurality of second sound absorbing grooves 14 are arranged on a side of the first sound absorbing panel 11 away from the body 1.
