Shot Peening
Shot Peening
Objective
to improve the fatigue strength of the parts, shots are spouted at a high speed to form compressive stress layer.
Characteristics
- Via periodic shot inspection and mechanical checking, heed should be paid for the parts not to be contaminated.
- Size of shot ball, hardness shall be properly applied to the parts complying with the customer request.
- The edges of the parts that will be peened shall be processed not to become too sharp according to the customer request, and there should be no mechanical damage nor foreign body and etc.
- Before processing, specimen works are needed to be done to confirm the reproducibility by the equipment’s initial setting conditions, and then the part works shall be carried out.
- After the completion of the works, no physical damage nor heat treatment not complying with the customer requirement shall do harm to the compressive stress layers of the parts.
