The metal parts on the stamping die in the machine tool, also called punching rods, punching needles or punches, are installed on the stamping die to perform continuous punching and punching operations to separate or plastically deform the processed material, thereby obtaining the Required finished or semi-finished products.

     Punches are also called punches, upper molds, male molds, punches, etc., and punches are divided into A-type punches, T-type punches, and special-shaped punches.

     The punch is a metal part installed on the stamping die, which is used in direct contact with the material to deform and cut the material.

     Die punches generally use high-speed steel and tungsten steel as materials, such as high-speed steel punches and tungsten steel punches, and high-speed steel is commonly used materials, commonly used CR12, CR12MOV, asp23, skd11, skd51, skd61, etc., Tungsten steel materials are generally used in punching and shearing dies with higher requirements.
