QB3 semi-through-hole pneumatic chuck Product features： The connection method between the chuck and the spindle conforms to national standards. The user does not need to change the structure of the machine tool, and only needs to be equipped with a flange that matches the size of the chuck to install it. The chuck body itself is a cylinder with a built-in piston, and the clamping and loosening actions are realized through the control mechanism of the tail of the spindle. The center of the chuck is hollow, which is suitable for processing longer bars.
