How to machining tungsten alloy

In cobalt, nickel as a binder in powder metallurgy method to burn into tungsten carbide ball alloy density is big, known as the high density alloy,Also known as the high proportion alloy.This kind of alloy can be by forging or heat treatment to increase the density and strength.usuallyThe tensile strength of Kekai tungsten & Molybdenum tungsten carbide rod alloy is sigmaB> 981 mpa, the hardness of> HRC40.

The coefficient of thermal conductivity of tungsten alloy is smaller than pure tungsten,Chip is granular,Chip knife - contact length is short,The cutting temperature tungsten carbide rods,

Easy to produce knife tumor and adhesive wear.

Good cutting tungsten alloy tool materials thermal conductivity,

The bending strength

Degree and higher toughness,

Good red hardness.

Recommended use tungsten carbide base fine grained ultra-fine grain cemented carbide,Such asYDl5,YM051And so on.Sharp cutting tungsten alloy, tool requirement, and to ensure the blade intensity. Cutting tool geometry parameter can be used:gammao8 = -O,Alpha.o= 8O,κR= 75O,REpsilon.= 0.5 mm.

Cutting parameter can be used:argumentC= 38 m/minF/r = 0.24 mm,a.= 1 mm

. When cutting without cutting fluid.
