Solid abrasive was pressed into the surface - 1.4301
Metallic solid abrasives are applied in the most different types, compositions and granulations. An application area is for example the remove of rust and scale layers at metallic surfaces. A blasting plant will many times directly preconnectedly in front of a drawing machine to be able to do without a pickling of the material. If the solid abrasive is damp or oily become, single grains of solid abrasives could be sticked to the material. Then they can be draged into the drawing stone and press themselves in into the drawing material. A part of these grains can then remain, as foreign material, in the material surface. The larger portion usually breaks out again and then little holes arise.
