Machine tool noise is a common problem in the manufacturing industry and is a potential threat to the health and safety of both workers and operators.
Machine tool noise refers to the noise and vibration generated in the process of machine tool processing. This noise not only affects the hearing and mental health of workers, but also negatively affects the precision and production efficiency of machine tools. In this paper, the mechanism of machine noise, the way of transmission and the method of noise reduction are studied.
By means of theoretical analysis and experimental research, the mechanism of machine tool noise, the way of transmission and the method of noise reduction are deeply studied.
Relative motion occurs between the parts of the machine tool, and friction will lead to friction and impact between the parts of the machine tool, resulting in noise.
The transmission path of machine noise: the transmission path of machine noise includes air transmission, solid transmission and liquid transmission. Among them, air transmission is the most important way of transmission, because machine noise is usually generated by the air gap between the machine tool and the table.
Vibration and friction of machine tools are effectively reduced by using shock pads, while hydraulic and pneumatic systems reduce noise by reducing friction and collision between machine parts.
Machine tool noise is a serious problem in the manufacturing industry. The noise of machine tools can be effectively reduced by adopting acoustic insulation technology such as shock pad, hydraulic system and pneumatic system. Therefore, manufacturers should take measures to reduce machine noise, to protect the health and safety of workers and operators, and to improve production efficiency.
