Carbide indexable CNC tools are tools used in machining for machining, also called cutting tools. The generalized cutting tools include both tools and grinding tools. At the same time, "hard alloy CNC tools" include accessories such as shanks and shanks in addition to cutting blades.
The cemented carbide rock drilling teeth violently impact the rock during rock drilling to achieve the purpose of drilling holes in the rock. During this process, the carbide teeth collide and rub against the rock, inevitably causing wear.
If you do not understand the density and influence factors of cemented carbide, it will easily lead to the wrong purchase of cemented carbide. This is a brief introduction of the density and influence factors of cemented carbide.
Cemented carbide sintering is the most basic and critical process in the production process, and it is also the last process. Sintering methods and equipment have a huge impact on the product. Conventional sintering methods include hydrogen sintering, vacuum sintering, hot isostatic pressing etc.
The platy molybdenum electrode can withstand higher current density, and is often used in a feed channel or a melting pool. The heating is relatively uniform, generally does not produce too strong convection, and the erosion of the electrode hole brick is smaller than that of the rod electrode.
Like tungsten, molybdenum is a refractory rare metal with a melting point of 2620 ° C. The bonding force between atoms is extremely strong, and the coefficient of expansion is small, the conductivity is large, and the thermal conductivity is good.
Molybdenum wire has high melting point, high strength and high modulus of elasticity, low expansion coefficient, low vapor pressure, good electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in lighting appliances, vacuum devices, machining and spraying.
