At the same time, cut aluminum and silicon steel sheet material, what NC blade?
The main problem of aluminum alloy is that it is easy to stick the knife in cutting, that is, serious accretion. Usually rely on large front angle, large back angle, and sharp blade, the front face of the knife, smooth surface, to ensure non stick knife, that is, by the angle of the tool to solve the problem, rather than material.
The aluminum alloy has no requirement, just press the silicon steel slice to do.
