Abrasion, adhesion and diffusion wear. The abrasion is mainly produced by carbides, sand gauges and hard cast finishes. Bonding of BUE has occurred at low cutting temperatures and cutting speeds. The ferrite part of the cast iron is most likely to be welded to the blade, but this can be overcome by increasing the cutting speed and temperature.
On the other hand, diffusion wear is related to temperature, which occurs at high cutting speeds, especially when using high strength cast iron grades. These grades have a high resistance to deformation, resulting in high temperatures. This wear is related to the role of cast iron and the tool, which allows some cast iron to be machined with ceramic or cubic boron nitride (CBN) tools at high speeds for good tool life and surface quality.
