Methods to improve the carbide cutting tools
Without changing the tool material at the same time, how can we improve the rigidity of working only from three aspects.
1. meet the machining requirements of the situation, try to choose a large diameter tool. Because it is the fourth power relationship between amplification effect will be very obvious, such as doubling the diameter, in theory, rigidity increases to 16 times, so should not be underestimated.
2. meet the machining requirements of the situation, try to shorten the length of the tool overhang.
3. In the tool diameter and length are defined overhang case, consider changing the tool material, namely changing the modulus of elasticity, modulus of elasticity select play material, such as cemented carbide tools.
Carbide Tool is the most widely used class of high-speed machining (HSM) tool material, such material is produced by powder metallurgy process, (usually tungsten carbide WC) particles and the soft texture of the combination of a hard metal carbides agent. Currently, there are hundreds of different components of WC-based cemented carbide, most of them are used cobalt (Co) as a binding agent, nickel (Ni) and chromium (Cr) it is also commonly used binders elements also can add other Some alloying elements.
