Primary roles include positioning and aligning workpieces, securing connections, and assisting in assembly and disassembly processes. It is particularly important in the assembly and processing process, which can improve the assembly accuracy and processing quality of the product. Positioning pins are widely used in applications requiring high precision and stability, such as precision instruments, fixture fixtures, etc.
