Smtcl cnc noise test

Machine tool noise is one of the main indicators for evaluating the dynamic performance of machine tools, and the magnitude of machine tool noise directly reflects the level of machine tool design and manufacturing. When the spindle of the machine tool is in idle rotation, the sound pressure level of the entire machine tool is tested, and the noise spectrum is analyzed under the maximum noise state to identify the main noise source of the machine tool and control and reduce its noise pollution.
