Particularity blade coating material

Particularity blade coating material
Compared with the bulk material , the coating thickness is thin because it is easy to generate size effect , that cutting discs  the coating thickness of the coating performance will be affected . Second , the coating with the volume ratio of the surface area is large, so the surface effect is significant , surface energy, surface state , surface scattering and surface interference great influence on its performance . In addition , the coating also contains a large number of grain boundaries and surface defect states , electrons have a greater impact during transport . Since the coating is a multi- grown deposited on the substrate , the substrate and the coating so that there is some interaction between such coating and the substrate appears and the adhesion between the adhesion problems , deposition coating layer will appear in the problem of internal stress , these problems are  circular blades of the coating has a significant impact on performance .
Surface effect is obvious surface effect refers to the solid surface , the internal stress in the coating ; coating nano multilayer structure and nanocrystalline composite structure , the coating excellent overall performance: As a structural member of wear, corrosion , oxidation, and fatigue , cracks and other damage initiation process is started from the surface of the member , and therefore attached to the surface layer of the component , high strength, wear resistance , corrosion resistance, anti-oxidation coating , can inhibit or slow down the destruction process , reach protection purposes, and is still the core part component toughness to meet members and other requirements for stiffness , give full play to the coating and the wet saw blades  substrate components excellent performance , thermal conductivity , sealing , excellent electrical conductivity of the coating, to meet and increasing component requirements for properties
Feed speed , depending on the processing of the material properties of each material when the cutting depth must have a certain range of the feed rate , if the speed is too high, will accelerate the wear of diamond or even fall off , causing the blade consumed quickly If the speed is too low , then they will make the process of self-sharpening blades can not be normal , so " blunt , skid " lost cutting capacity . Under normal circumstances , the feed speed is slower when cutting , sawing should be in uniform for the common typical materials , when the cutting depth is 20mm, recommend the following feed rate table for your reference , when the thickness changes, the cutting speed can be press the cutting area (cm2 / min) to conversion . Tip: The first feed or each piece of board should be reduced by half for the first three walks .
