Theory of hole punching

Jan 24, 2015 · Theory of hole punching The Theory Punching is a metal forming process that uses a press to force a tool, called a punch, through the workpiece to create a hole via a shearing process. The punch passes through the workpiece and into a die. The slug from the new hole is deposited into or completely pushed through the die in the process. metal hole punch and shear, metal hole punch and shear 1,807 metal hole punch and shear products are offered for sale by suppliers on , of which punching machines accounts for 4%, hydraulic press accounts for 1%.
