我们的返修方案如下：1、首先对四个大孔在图示位置采取激光熔覆技术进行焊

Our rework plan is as follows: <br>1. First, use laser cladding technology to weld the four large holes at the position shown in the figure, and thicken about 0.5mm on one side; <br>2. Mill off the parting surface of the upper and lower cabinets. 0.3mm; <br>3. After correcting the two sides, install positioning pins, tighten the bolts, and re-process the four large holes to the requirements of the drawing, and light out the two sides.

Our rework program is as follows:<br>1, first of all, the four large holes in the illustration position to take laser cladding technology for welding, about one-sided thickening 0.5mm;<br>2, milling to go up and down the box parting side single side about 0.3mm;<br>3, the two sides after correction, mounted positioning pin, tight bolts, re-processing four large holes to the drawing requirements, while lighting out the two sides.
