on dry cutting diamond tool Precautions

The current tool materials, such as new carbide, ceramic, CBN and PCBN and other high-temperature wear performance sufficient, able to dry cutting conditions.
  Dry cutting tool materials must have excellent hot hardness and wear resistance as to be effective to withstand  dry pads high temperatures during the cutting process; low friction coefficient, in order to reduce the tool and the chip and suppressing the friction between the surface temperature of the cutting rise. To implement the requirements of the tool dry cutting, it is necessary for the tool coating, is an important way to improve tool performance. In a robust surface coating of the tool base body and  hole saw blades wear resistant materials are very high, so that the cutting tool and the chip in the process of increase of a thermal barrier between, to prevent heat transfer to the tool base body decreases Tool wear and heat generation. The tool geometry, the dry cutting tool design should strive to follow the "low cutting temperature" design principles, the tool must be designed so  flap wheels that the processing structure of the heat generated in the process as little as possible, that the tool structure should strive to achieve low cutting forces and low friction.
