How to machining tungsten bar ingots and tungsten rods

Pure tungsten hardness and strength are high,Tungsten billets in cutting process, because of the coarse grains, easy to produceImpellers and make the rough surface processing.Cutting tungsten ingots and Kekai tungsten & Molybdenum tungsten carbide rods can be used to make carbide cutting tool materials,The commonly usedCemented carbide gradesYG6,YG8,YS2(YG10H),726And so on.With cutting ingot or tungsten bars, tungsten carbide can be used45O Lord Angle, wild car rake Angle and back Angle should be small,car and semi finished when the rake Angle, Angle after more appropriately. Pure tungsten wire extremely fragile, easy to collapse when cutting edge or peeling off,Cutting tool to cut out when, should reduce feeding, to prevent the tool breakage.
