You need to know the alloy milling cutter before grinding

The alloy milling cutter is a tool with high hardness, high bending strength and toughness. Its hardness value varies with the nature, quantity, particle size of carbide and the content of metal bonding phase, and generally decreases with the increase of the content of bonding metal phase. Alloy milling cutter is suitable for processing copper, […]
