Mainly used where, processing and parameters, milling aluminum blade
High speed steel milling cutter is harder to use than hard alloy milling cutter. High speed steel cheap, good toughness, but the intensity is not high, easy to let the knife, and wear resistance, hot hardness is relatively poor, high speed steel cutter hot hardness of 600 degrees, the hardness of about 65HRC, obviously when using high-speed steel milling of hard materials, if the coolant is not in place if it is easy to burn knife this is one of the reasons is not high hot hardness.Hard alloy cutter good hot hardness, wear resistance, but poor impact resistance, free fall edge will be broken, the hard alloy is made by the method of powder metallurgy materials, the hardness is up to about 90HRA, heat can reach to about 900-1000 degrees,
The composition of the milling cutter is made of cobalt and tungsten, and cobalt acts as a binder. The higher the cobalt content, the better the toughness of the tool, but the lower the tool hardness. The less cobalt content, the higher hardness, but lower tool toughness. There are cobalt tungsten steel knives. The processing is mainly Aluminum Alloy mills with three or two edged blade. Because the aluminum alloy compatibility is big, easy to stick the knife, easy to form accumulates the lump, generally the cutting tool can compare sharp, does not paint primarily
