In the process of using the high precision chuck, if it is used with high precision, it is usually boring first, so that the precision of the chuck is the precision of the spindle. For the high precision chuck after front end quenching, as long as it is used reasonably, the life factor does not need to be considered at all. The precision of the corn tooth type and special-shaped high precision chuck is determined by the manufacturing precision of the chuck.
The high precision chuck can not only be used to locate and clamp turning workpieces, but also can be used to position and clamp tools, grinding and milling workpieces or many other occasions. The external thread of the tie rod of the machine tool spindle is tightened with the internal thread of the rear end of the high precision chuck to generate axial tension, and then the conical surface called the locking angle at the front end of the machine tool spindle converts the axial tension into a perpendicular to the high precision chuck. The clamping force at the center of the chuck. Not only that, the clamping force can also be expanded by the locking angle. After calculation, it is known that the clamping force of the high precision chuck can be expanded by 3-4 times according to different locking angles.
The high precision chuck is a simple process device, but there are many main factors that affect the clamping force. An understanding of the basic principles can help the workpiece (or tool) to be properly clamped and troubleshoot quickly.
