Correspondingly, including the following steps: the invention also discloses a kind of high-intensitive fragile material processing method
The characteristic of the high-intensitive fragile material used first according to workpiece to be processed 7 selects flux metal silk, flux metal
Contain flux metal element in silk 10, one or more element contained by the high intensity fragile material is in flux metal element
Containing biggish solubility, flux metal after fusing is reacted with high-intensitive fragile material；By flux metal silk
10 are loaded on wire feeder 11；The angle that the feeding of flux metal silk 10 is adjusted by spherical shaft 113, by flux metal silk
10 are sent into wire feed steering mechanism 16；
Common flux metal silk: for the silicon sheet that is carbonized, the flux metal silk containing nickel, iron and/or chromium is used；
For carbide thin slices such as tungsten carbide, tantalum tungsten, the flux metal silk containing nickel, iron and/or copper is used；For sapphire
Using containing PbO-B2O3、PbF2The flux metal silk of-PbO and/or aluminium element.
Workpiece to be processed 7 is loaded on workpiece mechanical arm 6, and spreads fluxing processing in the upper surface of workpiece to be processed 7
The sealing powder 17 in molten bath, and make the partial denudation of the plan processing of workpiece to be processed 7；Fluxing crucible 81 is loaded in crucible machine
On tool arm 9, and the position of fluxing crucible is adjusted, contacts the lower ending opening of fluxing crucible with workpiece region to be processed, fluxing earthenware
The opening of 81 lower end of crucible is directly contacted with region to be processed；The diameter D of fluxing the lower end of the crucible mouthful depends on size to be processed.
Furnace body 1 is vacuumized, inert gas is then charged with, it is preferred that furnace body 1 is evacuated to 1 × 10-3Then Pa fills
Entering inert gas makes the intracorporal pressure 5 × 10 of furnace-4Pa.；So that the heater 2 of bottom of furnace body is worked, workpiece to be processed is heated
The heating of fluxing crucible 81 is given to design temperature, while by the magnetic inductive coil 82 in fluxing 81 outside of crucible, makes flux metal silk
Fusing, the induction stirrer 83 for opening fluxing 81 outside of crucible accelerate atom diffusion rate；The design temperature is not higher than
The softening point of workpiece to be processed, at least above 50 DEG C of the fusing point of flux metal.
Further, thermocouple 14 is measured by the workpiece temperature on 2 periphery of heater and obtains the temperature in workpiece to be processed 7
Degree and Temperature Distribution, the temperature of fluxing crucible 81 is judged by flux metal temperature measuring thermocouple 15.
Start wire feeder 11, by wire feed rolls 115 by flux metal silk 10 send constantly into fluxing crucible 81 and
Melt is molten into fluxing crucible 81, the atom of melted metal is reacted with the workpiece to be processed 7 of solid, solid it is to be processed
The atom of workpiece 7 is by diffusing into melted metal；Due to the entrance of workpiece atom, so that the rate of reaction subtracts
Slowly, therefore new flux metal silk 10 is sent constantly into, and is melted in fluxing crucible 81, and reaction speed will be maintained.
After measuring molten bath arrival projected depth according to molten bath ranging rod 12, fluxing crucible 81 and the movement of wire feeder 11 go to add
The next processing stand of work.
For needing to process the material of through-hole on workpiece to be processed 7, after workpiece penetration, flux metal melt falls on blanking
On baffle 5, for mustn't penetration workpiece, after reaching fabrication design size, by fluxing crucible 81 cooling, give heater 2
It reduces power and 11 counter motion of wire feeder and flux metal liquid is lifted into out molten bath, the molten metal in fluxing crucible 81
It is cooling after body is largely mentioned draw-out crucible, flux metal silk is all removed into furnace body 1, fluxing crucible 81 is moved away from into work
Above part；Workpiece is inverted finally by workpiece mechanical arm 6 and is toasted, so that residual flux metal drips.
Residual flux metal from workpiece drip after, to whole device slow cooling to room temperature, prevent the fast quickly cooling of workpiece
But there is stress or fracture, finally open furnace body 1, take out workpiece, acid can be passed through for the flux metal of Locally persistent
The mode washed removes, and completes the processing of workpiece.
Described device and method are reacted with the workpiece to be processed that high-intensitive fragile material makes using flux metal to realize
Processing to these materials, in process, material is not influenced by applied external force, the impact to high-intensitive fragile material
It is small, Precision Machining may be implemented to thin-wall high intensity fragile material, and it is broken not will cause its fracture.
