Repairing Technology for Nine Holes Warp of BOEING777 Airliner Main Wheel

The main wheel of BOEING777 airliner supports whole airplane weight,and when the plane starts and descents,it will brake now and then.The nine holes of main wheel make assistant function for brake.After the holes have been used for long time,mostly standing extrusion action,tiny distortion will occur.Because the wheel dimension precision is very high and the tiny distortion will maybe let the dimension overstep the tolerance.So the main wheel must be checked at one time.Underside,it main aims at the problem about the nine holes dimension over tolerance,then illustrates an effective technique for solving the problem.
