tool failure-build-up edge

  “Build-up edge”  occurs when the extreme forces at the point of contact between the cutting tool (tile cutter tool)and the workpeice weld small particles of the workpiece to the cutting tool(tungsten glass cutter tool). This type of failure is common when machining a soft, malleable workpeice, bonding material, high temperature alloy, stainless steel, nonferrous material, and thread processing, and drilling at slower than recommended cutting speeds. Experts from Changsha Langfeng Metallic Material Co.,Ltd suggest to control build-up edges:to increase feed rate and cutting speed use TiN coating inserts, coolant, use an insert with a positive rake angle.
