Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
Fig. 1 is a kind of processing method flow chart of slot antenna radiant panel provided in an embodiment of the present invention, as shown in Figure 1,
This approach includes the following steps：
Step S11：Blank dimension is selected according to the pre-set dimension of slot antenna radiant panel；
Step S12：Blank blanking, which is carried out, according to blank dimension obtains blank；
Step S13：The high temperature anneal is carried out to blank, annealing temperature is 450-560 DEG C, annealing time 6-
10h；
Step S14：Utilize fixture clamping blank；
Step S15：High-speed machining is carried out to the blank of fixture clamping, obtains the slot antenna radiation with coupling slot
Plate.
In one embodiment of the invention, the length of blank dimension is a1, width b1, thickness c1, slot antenna
The length of the pre-set dimension of radiant panel be a2, width b2, thickness c2, a1 ratio a2 big 10-20mm, b1 the ratio big 10-20mm of b2,
The big 1-2mm of c1 ratio c2.Preferably, a1 580mm, b1 540mm, c1 2mm；A2 is 560mm, b2 520mm, c2 1mm.
It is not only not easy clamping, increases high-rate wireless LAN if blank dimension selection is excessive about the selection of blank dimension
Time, and raw material are wasted, if blank dimension selects too small, a small amount of change that blank can be made to be generated in clamping and milling process
Shape focuses on part edge, influences the flatness of slot antenna radiant panel.In this embodiment, slot antenna radiant panel is default
Size is 560mm × 520mm × 1mm.Preferably, blank dimension is 580mm × 540mm × 2mm, compared to existing frequent selection
Blank dimension 565mm × 525mm × 2mm, can make the part edge generated in process on a small quantity deformation be transferred to increasing
On the blank added, the outer rim of deformation is cut off finally by processing, the slot antenna radiant panel of no deformation is left, makes slot antenna
The flatness of radiant panel meets design requirement.
Blank dimension is selected according to pre-set dimension 560mm × 520mm of slot antenna radiant panel × 1mm, is carried out under blank
The blank that size is 580mm × 540mm × 2mm is obtained after material, when changing annealing temperature and the annealing used in the high temperature anneal
Between, the influence of research annealing temperature and annealing time to blank flatness selects best annealing temperature and annealing time.
Flatness refers to the deviation for macroscopical height of concave convex relative ideal plane that substrate has, i.e. flatness error value, is
Tested actual surface is compared with ideal plane, line value distance between the two, or several in actual surface by measuring
The relative height differential of point, then the flatness error value indicated with line value that converts.As it can be seen that the value of flatness is smaller, illustrate tested real
Closer to ideal plane, surface is more smooth on border surface.Generally, 0.1mm is not more than to the planarity requirements of gap aerial radiation plate.
The influence of 1 annealing temperature of table and annealing time to gap aerial radiation plate flatness
Table 1 gives different annealing temperatures and the corresponding slot antenna radiant panel plane degrees of data of annealing time, from table 1
In as can be seen that use the flatness for the slot antenna radiant panel that the annealing temperature of the prior art and annealing time produce for
0.2mm is more than 0.1mm, does not meet planarity requirements, and the prior art is typically to be carried out at multiple annealing to blank in this case
It manages to eliminate stress, but repeatedly annealing can extend the process-cycle of part, and the residual of feed stock material can not be completely eliminated
Residue stress.
And this programme be respectively adopted annealing temperature be 450 DEG C, 500 DEG C, 560 DEG C, corresponding annealing time be respectively 10h,
When 8h, 6h, the flatness for the slot antenna radiant panel produced corresponds to 0.09mm, 0.08mm, 0.095mm, namely obtain
Slot antenna radiant panel flatness is all not more than 0.1mm, meets requirement of the slot antenna radiant panel to flatness.It follows that
The present invention program need to only carry out a high temperature anneal and can reach requirement of the slot antenna radiant panel to flatness.Wherein move back
Fiery temperature is 500 DEG C, and slot antenna radiant panel flatness when annealing time is 8h is minimum, illustrates that selective annealing temperature is 500
DEG C, when annealing time is 8h, obtained slot antenna radiant panel is the most smooth.

For high-rate wireless LAN using the processing method of " small cutting-in, fast feed ", 95% milling heat can be by chip and cooling
Liquid band is walked, in this way, work piece surface keeps room temperature substantially, moreover, Milling Force and milling steel fiber that High-speed machining generates are all very
Small, such cutter will not cause to squeeze to work piece, to reduce work piece deformation.The lathe used in the present embodiment
The speed of mainshaft is 40000rpm or more, cutter rotating speed n=30000r/min, amount of feeding f=3000mm/min, cutting-in ap=
0.2mm cuts wide ae=4mm, and the slot antenna processed radiation plate surface can be made not have metamorphic layer and a micro-crack, thermal deformation compared with
