3 jaw self centering chuck
The three-jaw chuck is composed of a chuck body, a movable jaw and a jaw driving mechanism. Under the three claw guides on the three-jaw chuck, there are threads that mesh with the flat threads on the back of the bevel gear. When the small bevel gear is rotated through a square hole with a wrench, the disc gear rotates, and the back plane threads are simultaneously Drive the three claws toward or out of the center to clamp workpieces of different diameters. It is used to replace three anti-jaws on three jaws to install workpieces with larger diameters. The self-centering accuracy of the three-jaw chuck is 0.05-0.15mm. The accuracy of machining a workpiece with a three-jaw chuck is affected by the accuracy of the chuck manufacturing and its wear after use.

The chuck will be need replace, so we need to disassemble it. First, find a few (inner hexagon) screws from the back of the positioner chuck, remove it, and then use a wooden or copper rod from the front to the back. Hammering the disk inside the three claws will take out the disk. Inside is a small disc for positioning and dust protection. Remove it. After removal, find a few flat-head screwdriver screws at the corresponding positions behind the three claws of the chuck and remove it. This way, you can take out the bevel gear with the three claws, and then carefully remove the disk with the flat rectangular thread. Take it out and remove the three claws from the front, so that the three claws are removed. Generally, the interior is polished or cleaned after disassembly, and the flat rectangular threads are cleaned. The teeth on the back are often stained and cleaned. Try not to hurt it with a file or other hard, gently put it in after cleaning, hammer it with a wooden stick, then install the bevel gear shaft (this also needs to clean the dirt between the teeth), and screw in the screws that fix it. When installing the small discs and large discs on the back, carefully check whether their contact surfaces are bumped. Be sure to check them carefully. This is important to the accuracy of the entire chuck. Use a file to carefully remove unevenness. Finish the place, tighten the screws, and you're done.
