Process of Processing and Testing

1. Steel plate necessary airframe welded fuselage

2. Rough machining of gantry milling machine

3. Internal stress relief treatment:

1) Tempering (annealing) warmth treatment of gantry beam and facet arm

2) Aging treatment of mattress vibration

4. Finishing:

1) The imported pentahedron machining center (mother machine) is used to stumble on and fix the physique at one time;

2) The installation reference floor of the overall precision milling X, Y, Z three-axis bidirectional information rails and racks;

3) After the datum surface processing is completed, beneath the same positioning accuracy, the one-time processing of the positioning pin holes, constant installation holes and screw holes of the set up reference surface of the X, Y, and Z three-axis bidirectional information rails is completed.

5. Transfer to the assembly system and assembly

6. Quality inspection process

1) Precision ruler and dial indicator: check the straightness of X, Y and Z axes

2) Precision ruler, dial indicator, spirit level, and laser interferometer realize the parallelism between X, Y, and Z guide rails

3) Precision perspective ruler, dial indicator, special inspection tool, ball bar: become aware of the verticality of X, Y, Z three-axis guide rails

4) Dial indicator, extraordinary inspection tool: spindle verticality detection

5) Special inspection tool, dial indicator, precision angle ruler: realize the parallelism and perpendicularity of X, Y, Z rack and lead screw and the corresponding linear axis (guide rail)
