In the work process, the gantry type CNC plasma cutting machine will produce a variety of pollution, such as: arc pollution, dust pollution, noise pollution and so on. In fact, as long as it is a CNC cutting device, this problem exists. Then, how can we prevent the various pollutions produced by the CNC gantry plasma cutting machine? And listen to the Wuhan resistance to digital control slowly:
1. Prevention of arc radiation pollution: Arc radiation is mainly infrared radiation and visible radiation. The gantry CNC plasma cutting machine operator must bring the top cover and gloves to protect the face, hands and neck. Masks are best to prevent the lens, when cutting, you can use water cutting method, use water to absorb light radiation.
2. Prevention methods for dust and dust pollution: The gas flow during cutting is large, and a large amount of vaporized metal vapor, ozone, and nitride during the cutting process. Causes a lot of dust to rise. Therefore, you must configure a good ventilation equipment to do dust control measures. During the cutting, an exhaust device can be installed below the grid table, and a water cutting method can also be adopted to reduce dust.
3, the prevention of noise pollution: CNC plasma cutting arc cutting will produce high-intensity, high-frequency noise, should use automatic cutting, the operator working in the sound insulation room. A water cutting method can be used and water can be used to absorb noise. In addition, the use of water curtain cutting torch can also greatly reduce the noise.
4, the method of prevention of electric shock: In the manual operation, there is a danger of electric shock. Therefore, when using the power supply, it must be ensured that the grounding is good, and the torch and the touched part of the hand must be reliably insulated. The switch must be covered with an insulating rubber sleeve to avoid direct contact with the switch.
5, electromagnetic field prevention methods: high-frequency electromagnetic on the human body has a certain degree of harm. The main prevention measures are: arcing frequency selection is suitable in 20 ~ 60Hz, high-frequency oscillator with shielding shield, workpiece to ensure good grounding; arc ignition in the main arc immediately after the ignition, should cut off the high-frequency oscillator power supply; When high-frequency sparks are used to check the centering of the electrodes, the time should be minimized.
The above five kinds of pollution sources can prevent us in daily production and use. In order to protect our health, we can adopt the above five methods.
