Polishing process belongs modification of surface topography. On surface grinding or coating a variety of different polishing methods. In addition to large quantities of parts for Troyes polishing, as well as commonly used in the production of brush cutter method and blasting method. These methods are not new, has been used for many years in the production of the cutting insert, such as cauliflower-like surface structure for polishing cvd thick coating. Polished cutting insert after cutting over 6 min exhibited a very uniform wear. Without polishing the blade parallel to exhibit microscopic cracks, which can lead to rapid wear band broadening, and the tool early failure.

These methods are now often used for polishing pvd coating. As in a hole machining pvd coated blade surface, you can see the structure of the pvd arc method is called "droplet" of. The role of these droplets as riverbed stones, hindering chip exclusion process, which is particularly disadvantageous in the hole machining. If frictionally make and less rapid removal of the chips, then the contact time between the chip and the tool is reduced, the heat transfer to the tool is also reduced. Unhindered chip exclude smaller cutting forces, avoiding the drill cuttings, milling grooves produce occlusion and clogging. Depends on the quality of the polishing process parameters to adjust the selection and polishing methods.
