Many rotating workpieces, especially high-speed rotating workpieces, have dynamic balancing requirements, and the higher the working speed, the stricter the requirements. The common balance force method is that the workpiece is fixed on the balance machine for rotation, and the size and orientation of the workpiece imbalance are indicated according to the balance machine, and then de-weighting or weighting is performed to achieve the leveling requirement. For longer rotating workpieces, it is generally separated into two sections for separation and trimming. However, when separating and trimming, the two separation planes interact with each other. You have to trim this side, and there is also a change there. This change brings great trouble to the trimming work, and it is difficult to achieve balance between the two separation planes at the same time. From practice, we find the following trimming method. The shape of the processing test piece and the loading method on the balancing machine are as shown in FIG.
Use a thread insert kit to replace a stripped thread or add a threaded insert into sheet metal, fiberglass or other brittle material. Choose from kits with standard inserts or helical inserts (also known as helicoil inserts). Thread repair kits include everything you need to repair or install threaded inserts, including a hand drill and installation tool to speed maintenance and reduce downtime.
