Today, I will take you to learn about the cutting process of tungsten molybdenum alloy products. So when you cut the tungsten alloy products, you will know how to operate it. I hope that’s useful for you. The tungsten molybdenum alloys sintered by powder metallurgy method and made cobalt, nickel as a binder have high density, which is called high density alloy, and is also known as the heavy alloy. This kind of alloys can be grown by forging or heat treatment to increase their density and strength. The tensile strength of tungsten and molybdenum alloy is usuallyσb>981MPa, the hardness is >HRC40.

The thermal conductivity coefficient of tungsten and molybdenum alloy is smaller than pure tungsten. The chip is granular, the contact length of the tool blade is short, and the cutting temperature is very high, which is easy to cause knife sticking and adhesive wear. The cutting tool material for tungsten molybdenum alloy has good thermal conductivity, flexural strength and higher toughness, red hardness. It is recommended that it can use fine grain WC ultra-fine grain cemented carbide, such as YDl5, YM051 etc. When cutting tungsten alloy, the cutting tools require sharp edges and ensure the cutting edge strength.

Tool geometry parameters can be selected:
γO=-8º、αO=8º、Κr=75º、rε=0.5mm
Cutting parameters can be selected:
νC=38m/min，f=0.24mm/r，ap=1mm. No cutting fluid is used during cutting.

The above is the cutting process of tungsten and molybdenum alloy products that I introduced for you.
