Description

Technical Field

During the abrasive flow machining process, although the abrasive can be effectively controlled in and out, the abrasive grinding area cannot be controlled. Traditional fixtures can only clamp the workpiece. While grinding the damaged layer, the abrasive will rub and grind the smooth intact surface, causing wear and damage to the workpiece, seriously affecting the beauty of the workpiece and the safety of subsequent use. Summary of the invention
