Heat Cutting for Remanufacture Hardness Deposited Materials

Abstract:

Three cutting tools, YG610, Si3N4 ceramic tool and CBN were adopted for heat cutting deposited materials. The test results show that though the impacts to the tools reducing, the CBN still break seriously. The condition by Si3N4 ceramic tool is better than CBN, whose types of tool failure change from breakage to wear. The YG610 is best material for heat cutting, whose minimum VB value is only 0.3mm. In the experiment, the wear increase with the increasing of heating temperature, cutting speed, cutting depth. But it decreased with feed rate. The analysis results show that the red-hardness is most importance factor for wears of YG610.
