However, for parts such as bolts, the installation process of small bolts and CNC fixtures is more difficult, and the number is large, and the overall operation efficiency is low. Therefore, a vacuum absorber is urgently needed to replace conventional CNC fixtures to install bolts. Utility Model Content
