2) reduce the clamping force of the impact on the process of taking the following measures to reduce the influence of the clamping force: ① use of radial clamping, the clamping force should not concentrate on a radial cross-section of the workpiece, but it should be distributed over a large area, to reduce the unit area on the workpiece is subjected clamping force. As the workpiece can be mounted in an opening in the ring of a suitable thickness, in conjunction with the clamping ring together. May also be used to increase the contact area with special gripping.When in the hole location, should adopt the open-type mandrel fixture. Location ② clamping force should be selected in a strong rigid parts of the site, in order to improve the deformation of thin-walled parts under the clamping force. ③ changing the direction of the clamping force, the radial clamping to axial clamping. ④ strengthen the system out on the workpiece rigid projections or process technology to reduce the clamping screw deformation, the clamping claw special structure of the processing, the processing of the cut end of the flange.
