[0002] In the modern machinery manufacturing industry, milling is one of the important processing methods and is widely used in the processing and forming of metal parts. In the traditional milling process, the clamping method of the workpiece directly affects the processing accuracy and efficiency. Generally speaking, when using mechanical clamps to fix the workpiece, due to its complex structure, cumbersome adjustment and poor adaptability, it often leads to problems such as unstable clamping and jitter during processing, which affects the surface quality and dimensional accuracy of the product. In order to solve the above problems, pneumatic clamps have gradually become an ideal choice in milling processing because they can achieve rapid clamping and loosening, convenient operation and strong adaptability. Pneumatic clamps can control the clamping force through air pressure, thereby improving production efficiency while ensuring processing accuracy.
