The VSM self-sharpening solution
In VSM ACTIROX abrasives, the geometrically shaped ceramic abrasive grains wear down at a uniform rate. As they do, they constantly produce new, razor-sharp cutting edges.
Thanks to the microcrystalline grain structure of VSM CERAMICS Plus and VSM CERAMICS, the ceramic grain wears down in a defined manner during grinding, continuously generating new, sharp cutting edges. This is what we call the ‘optimized self-sharpening effect’.
Aluminum oxide and zirconium oxide are finely dispersed throughout the microstructure of VSM ZIRCONIA ALUMINA. During the grinding process, the materials wear down alternately.
VSM COMPACTGRAIN long-term abrasives are made up of a granulate that contains numerous abrasive grains. Worn abrasive grains are torn off by the grinding forces to expose the sharp tips of unused grains.
Additional grinding-active layers for specific applications
The VSM TOP SIZE coat is recommended for dry grinding of heat-resistant stainless steels and non-ferrous metals. Thanks to the additional layer with its grinding-inducing additives, the cutting performance is improved whilst the temperature in the contact area is reduced. In addition, the useful life of the abrasive is dramatically enhanced.
The anti-adhesive layer ALU-X is primarily used for machining non-ferrous metals. It prevents chip adhesion and thus clogging of the abrasive. It also enhances the service life of the abrasive.
Abrasives with an antistatic coat are primarily used for woodworking. They prevent the build-up of an electrostatic charge so that the grinding dust does not adhere to the workpiece or the machine.
