What is the dust-free dry grinding process in automobile painting?

1: dry grinding saves time and effort: the output rate of the factory and station using water mill is much lower than that of the factory using dry grinding. Because the cutting force of manual water mill is far less than that of machine dry grinding, it takes painters three times as long to grind the same workpiece with water mill as that with machine dry grinding. Moreover, the painter of water mill must wait until the working area of each water mill process is dry before proceeding to the next process. In this way, whether it is the time spent between processes or the waiting time between processes, dry grinding is much shorter than water grinding, and painters who use automatic dry grinding can complete more cars at the same station.

2. Environmental protection: The environmental protection of dry grinding process is obvious. The water mill process will not only produce a lot of sewage, but also the painter's hand will hurt his opponent all the year round, especially in the northern part of China, and the painter's work will become harder in winter. In contrast, the dry grinding process does not need water and adopts dust-free technology, especially the dry grinding system with active dust collection. A clean and environmentally friendly painting workshop is completely achievable. With the improvement of China's labor and environmental protection laws and regulations, coupled with the strengthening of workers' awareness of self-protection, environmental protection has become an unavoidable problem.

3. The paint surface treatment effect is good. It is also the most important point. The biggest advantage of dry grinding technology is that the paint surface treatment effect is good, which greatly reduces rework. Because the dry grinding process is mechanical grinding, the surface of the workpiece is very flat, and because there is no water on the surface of the workpiece in the whole process, the common rework problems such as orange peel, bubbles and sand marks in water mill are avoided.
