How Circular Blades Reduce Oxidized
Time date:2016-12-28 08:44

When the cutting temperature of 700 ~ 800 ℃, the oxygen in the air and carbide in the cobalt and tungsten carbide, titanium carbide and other oxidation, resulting in relatively soft oxides (such as Co3O4, CoO, WO3, TiO2, etc. ) Is scraped by the chip or the workpiece to form wear, which is called oxidation wear. Oxidative wear is related to the adhesion strength of the oxide film. The lower the adhesion strength is, the faster the wear is; otherwise, the wear can be reduced. In general, the air is not easy to enter the contact area of the chip, the oxidation wear is most likely to be formed at the working boundary of the main and secondary cutting edges.
