The milling of hard cutting workpiece hard alloy cutter knife edge collapse and Countermeasures of reason
The cutter model is wrong, the milling can not move the material, the resistance is big, then the knife breaks. Use 75 degrees to make the plane
Hard to turn materials require different speeds and special turning tools. There is a reasonable amount of feed. Ordinary alloy knives are very easy to break
Difficult to cut material hardness and strength are very high. The tool produces a great resistance to cutting, and the tool is difficult to resist such a large cutting force, so the tool will be damaged.There are solutions:Heat the treated material to reduce the hardness.Replace cutting tools with better machinability.Change the tool angle to resist greater cutting force.Reduce cutting parameters.Change the processing process, such as using EDM
