Determine the material of the tool according to the machining type and workpiece material. It is a common knowledge in the whole machining industry to match tool materials with workpiece materials. But not everyone knows how many conditions this so-called match will satisfy. Next, we will introduce ‘how tool materials and workpiece materials can match mechanical, physical and chemical properties’.
How do the mechanical properties of tool materials and workpieces match?
The mechanical properties are mainly designed for the strength, toughness and hardness of the tool and workpiece. All kinds of tool materials are arranged in order of bending strength from strong to weak: high-speed steel, hard alloy, ceramic tool, diamond and cubic boron nitride tool. In order of toughness from high to low: high speed steel, hard alloy, cubic boron nitride, diamond and ceramic tool; In order of hardness from high to low: diamond tool, cubic boron nitride tool, ceramic tool, hard alloy and high speed steel.
