The processing for defect products of the stamping 2

defect phenomena including crack, wrinkle, strain, uneven thickness, not forming etc.

(1) screw drill hole diameter and depth (bottom hole size according to the thread specification to determine the size); external threads to process to the thread size outside the circle (size is determined according to the specification of thread)

(2) Produce thread: internal thread use the corresponding grade; external thread by thread cutter or die threading.

(3) Defect phenomena including wire arbitrary deduction, not uniform size, thread gauge inspection unqualified materials etc. According to the requirements of the user to select copper, aluminum, low carbon steel etc which has lower deformation resistance, and good the plasticity good ductility of metal or non-metal.

For the inspection specification, according to the requirements to determine the inspection specification, like thread inspection has the GB thread gauge, hole inspection has the plug gauge or buy GB standard size gauge.
