Preferably, the fore-and-aft clearance between adjacent gas nozzle is 7-15cm.The setting can make the equal energy of workpiece surface each position
Reliably it is ejected into high pressure gas.
Preferably, the work top tilts 5 ° -10 ° along left or right side.The setting can make the old erosion after reaction
Accumulating for old etching solution can be further reduced by the effect natural back flow to etching groove of self gravity by carving liquid.
Preferably, the nozzle is uniformly distributed and is connected by hose with jet pipe, all nozzles also pass through a same left side
Right pendulous device is connected with spraying rack.The setting can make all nozzles uniformly swing, and etching solution projected area is wider, more
It is even, so as to make lateral erosion width reduce and more evenly.
Preferably, the amplitude that swings of the device that swings is 3-8cm.Reasonable swing angle can make to lose
It is wider to carve liquid projected area, injection more evenly, and is not easy to be ejected into outside workpiece and causes to waste.
Preferably, the device that swings also passes through oscilaltion device and is connected with spraying rack.The setting is so that spray
Mouth can not only be swung in left-right direction, but also can be gone up and down along the vertical direction, when first half etchant flow surface is not carved also, etching
Speed is slower, and the height of nozzle can be reduced by oscilaltion device so that etching solution is easier to enter workpiece, and later half
In etchant flow, the height of nozzle can be increased by oscilaltion device, to guarantee front and back etchant flow etching speed basic one
Cause, so as to further decrease lateral erosion width and lateral erosion width more evenly.
