Materials
SKH51 is a high-speed steel, the Japanese JIS grade, equivalent to the German DIN 1.3343, the United States M2.
It belongs to tungsten-molybdenum tough high-speed steel. The steel has fine and uniform carbide particles, high toughness, excellent cutting performance and good thermoplasticity. It has good wear resistance, especially resistant to high temperature of 600 °C without softening. It is suitable for manufacturing various tools that are wear-resistant and impact-resistant, advanced die, screw die, tools that require toughness and shape, milling cutters, drill bits, etc.
Processing
As the guide bush and guide pins with the size of the high precision requirements, and the inner cylinder and the outer circumference should be coaxial, therefore when manufacture the guide bush, it need to grinding in the inner cylinder first, and then install the mandrel grinding cylindrical surface.
