To date, a lot of varieties of abrasive equipment for surface processing have been invented to date. It is safe to say that the petal circles have now firmly occupied their niche. And this is not without without reason, since a number of their operational properties make them more practical and less costly compared to analogues. So how are they still different from ordinary grinding circles?
First of all, these are the constructive differences of the 3m petal circles, namely, strips of abrasive material are fixed on a conical base in a fan -up way. It is this difference that gives a lot of advantages. So when working with petal circles due to the intermittent structure of the working canvas in the processing zone, the smaller temperature. As a result, we get a grinding without overheating of the processed part, and, therefore, without traces of fusion and jogging spots.
In addition, circles are used until complete wear, while there are no losses as processing, since with wear, each petal opens a new strip of abrasive and so on until the very end. All this excludes the greasy of the disk during operation. It is worth noting that wear occurs evenly throughout the entire area. Another distinguishing feature is the presence of the so-called mini-disks with a diameter of 45 and 75 mm. They are suitable for all types of processing of small details and elements, as well as for working in hard -to -reach places – bends, angles, contour surfaces.

High performance is ensured by the correct selection of size, type of abrasive material and its granularity. The grains of zirconium electrocorundum most often act as an abrasive, however, it is often the use of other varieties of corundum and silicon carbide.
Even in the presence of so many advantages, the use of petal circles is advisable if there is no question about the grinding area for one run, since the abrasive petals are located only along the ring, and, consequently, the processed surface is smaller. If you need to sharpen the tool, process the ends, welds or perform any other flat -grinding operations, then the choice of petal circles will be optimal and will achieve high results at lower costs.
