Preferably, in second step, before carrying out gluing clamping, earlier part edge is carried out encapsulation process, prevent that powder that process produces is penetrated on the glue and causes losing viscosity.
Preferably, in the 3rd step, 10000～15000 rev/mins of the rotating speeds of high rotary speed parameter selection main shaft.
Preferably, in the 3rd step, during roughing, cutting depth is 6～10mm; During fine finishining, cutting depth is 2～4mm.
Preferably, in the 3rd step, the amount of feeding is chosen revolution per tooth 0.15mm～0.3mm.
Preferably, the 4th step comprised:
(1) machine after, remove the dust of piece surface with dust catcher.
(2) remove Yu Bianshi, adopt hand saw blade to remove the surplus limit of part.Remove Yu Bianshi, adopt aviation to clean gasoline and clean the machine oil that is applied to the saw blade surface.
(3) with the burr of fine sandpaper polishing part, fine sandpaper is selected 1000 purpose sand paper for use.
(4) machine after, in the sealing bag of packing into as early as possible, and put into the silicon drier, adopt plastic packaging machine to seal.Sealing bag selects for use aluminium foil to mould bag again.
Preferably, in the 4th step, when processing parts, do not add water.
The operating personnel wears emgloves in part processing whole process, avoid part is polluted.
Rigidity closed-cell foam machining process of the present invention is used in the molding procedure of rigidity closed-cell foam, and the dust that its process produces is less, has guaranteed the dry and cleaning of piece surface, has also protected equipment simultaneously.
Compared with prior art, the invention enables product surface quality good, the dust that process produces is less, has reduced the infringement to process equipment, and can keep the dry and cleaning of piece surface.
Though background technology is based on aviation composite hatch door door body core and is elaborated, the present invention can be used for the moulding of the rigidity closed-cell foam in any manufacturing field.
