Any product will wear for a long time. For the high precision chuck, if the wear exceeds a certain limit, the problem of not holding the workpiece will occur, which will directly affect the machining accuracy and production efficiency, and virtually increase the manufacturing of the fixture. The cost has brought huge economic losses to the enterprise.
In order to improve the wear resistance of the chuck, it is necessary to increase the hardness of the chuck, and if the hardness is too high, the elasticity of the chuck is weakened, and the spring flap is easy to break. What improvement measures are needed for the high precision chuck?
1. Conical surface of the finishing chuck: use threaded tires to ensure the machining accuracy of the chuck body. After finishing each surface of the chuck body and drilling the equally divided holes, the conical surface is turned. When turning the conical surface, the threaded surface is used as the positioning reference. , it can ensure the machining accuracy when turning the conical surface. First screw the chuck to the threaded tire, then install the threaded tire on the machine tool spindle, and then use the small tool holder on the pallet to cut.
2. Grinding the inner diameter of the high precision chuck head: Use the inner diameter tire to ensure the accuracy of grinding. The inner diameter of the chuck is also a positioning surface. Use the inner diameter of the chuck to clamp the clamp, and then use the clamp to clamp the workpiece. The accuracy also directly affects the accuracy of the workpiece to be processed, which requires that the inner diameter and the conical surface must be coaxial. Use a special grinding inner diameter tire to clamp the chuck, and the tire is positioned with a conical surface. After grinding, the inner diameter of the collet can generally reach 0.02mm relative to the conical surface coaxiality.
