Some problems that must not be neglected in tool grinding

Tool materials Common tool materials in tool grinding are: high speed steel, powder metallurgy high speed steel, hard alloy and PCD, CBN, cermet and other superhard materials. High speed steel tool sharp, good toughness; Carbide cutting tools have high hardness but poor toughness. The density of carbide tool is obviously higher than that of HSS […]
