To date, many varieties of abrasive equipment for surface treatment have been invented. It is safe to say that the petal circles are now firmly established in their niche. And this is not without reason, since a number of their operational properties make them more practical and less costly than their counterparts. So how do they differ from conventional grinding wheels??
First of all, these are the structural differences of the 3M flap discs, namely, the strips of abrasive material are fixed on the conical base in a fan-like manner. It is this distinction that provides many benefits. So, when working with flap wheels, due to the discontinuous structure of the working blade, there is a lower temperature in the processing zone. As a result, we get grinding without overheating of the workpiece, and, therefore, without traces of burns and tarnishing spots..
In addition, the wheels are used until they are completely worn out, while there are no losses in the quality of processing, since during wear, each petal opens a new strip of abrasive and so on until the very end. All this eliminates the grease of the disc during operation. It should be noted that wear occurs evenly over the entire area. Another distinctive feature is the presence of so-called mini-discs with a diameter of 45 and 75 mm. They are suitable for all types of processing of small parts and elements, as well as for work in hard-to-reach places — folds, corners, contour surfaces.

High productivity is ensured by the correct selection of the size, type of abrasive material and its grain size. The abrasive is most often the grains of zirconium electrocorundum, however, other types of corundum and silicon carbide are often used..
Even with so many advantages, the use of flap wheels is advisable if there is no question about the grinding area in one run, since the abrasive flaps are located only along the ring, and, therefore, the surface to be processed is smaller. If you need to sharpen a tool, machine ends, welds or perform any other surface grinding operations, then the choice of flap wheels will be optimal and will allow you to achieve high results at a lower cost..
