How is the knife made?

Each knife is a special billet. After hot forging, each blank keeps its special hardness and rigidity. How high the temperature is, how fast it is heated and how fast it is cooled is the accumulation of experience.

Select equipment according to material, hardness, thickness and size. General selection method: 2mm is 60T, 2mm is 60T or 80T, 3mm and 3mm are 80T or 120T. ..

The time should be just right, too little will make the temperature of the material insufficient and the structure transformation incomplete, which will lead to insufficient or uneven hardness, while too long will make the structure rough, fragile, poor toughness and decarbonize by oxidation.

Extended data

1, the cutting performance of the tool directly affects the production efficiency, processing quality and production cost. The cutting performance of the tool depends on the material of the cutting part first.

2. The better the thermal conductivity of the tool material, the easier it is to conduct the heat generated during cutting, thus reducing the temperature of the cutting part and reducing tool wear.

3. In order to facilitate manufacturing, the tool material is required to have good machinability. Include hot workability (thermoplasticity, weldability and hardenability) and machinability.
