His English name is Rotary, RO machine for short, and he is also called Rotary Throwing Machine.
This machine will only force the polishing machine to rotate in one direction, rotating clockwise. And the function of this machine: It can remove deep scratches, that is to say, it can remove 600-800 mesh sandpaper prints, and it can also remove 1500-2000 mesh sandpaper prints. It is a necessary polishing equipment for every automobile art technician.
Advantages of straight machine: high efficiency, very fast removal of scratches, necessary equipment for every automobile art technician.
Disadvantages of straight machine: low safety, fast temperature rise, glare after polishing. In the construction process, especially the corners and corners, it is easy to be thrown through if you are careless. Even if you are an "veteran driver" who has been in the automobile and beauty industry for 10 or 20 years, you may lose your mind, even if your polishing level has reached the level of perfection. There will also be more or less glare. If your technique is not good, more glare will be produced after polishing, which will turn the car into a "rainbow car". I believe that many technicians will read this, and they will think: just cover it up with car wax. I tell you, you are not a qualified car beauty!
