Embodiment 1

[0020] Embodiment 1: This embodiment is a liquid jet electrolysis-laser composite processing method. First, a laser generator is used to generate a laser beam to process holes on the workpiece. Jet liquid beam, the laser beam removes materials under the guidance of the jet liquid beam, while the jet liquid beam cools and scours the laser processing area, it also performs electrochemical anodic dissolution, which can effectively reduce the thickness of the recast layer to less than 0.01mm, or even completely eliminated.

[0021] The spray liquid is ultrapure water, and a neutral saline solution can also be used; the ultrapure water is deionized water or distilled water; the neutral saline solution is a low-concentration neutral saline solution with a concentration of 3%-15% .

Embodiment 2

[0022] Embodiment 2: This embodiment is a liquid jet electrolysis-laser composite processing device, including a laser 2 and a workpiece mounting fixture 12, and also includes a DC power supply 1 and a liquid jet device 23, wherein the liquid jet device 23 includes a jet device installation Seat 3, insulating adapter seat 5, cathode 9, focusing lens 4, protective mirror 6, insulating jacket 7 and nozzle 11, injection device mounting seat 3 is connected with laser 2 and insulating adapter seat 5 respectively; cathode 9 is connected with insulating adapter The base 5 is connected, and the hollow part of the cathode 9 forms a cavity for jetting liquid, and the cathode 9 is installed coaxially with the laser beam generated by the laser 2; the focusing lens 4 and the protective mirror 6 are respectively fixed on the upper and lower ends of the insulating adapter 5; 9 is provided with an insulating jacket 7 outside, and the nozzle 11 is fixed on the lower end of the insulating jacket...

Embodiment 3

[0026] Embodiment 3: The structure of this embodiment is basically the same as that of Embodiment 2, and the power supply 1 is a DC pulse power supply.

[0027] During the work of the device of embodiment 2 and embodiment 3, first the clamp 12 is connected to the positive pole of the power supply 1 through the conductive block to make the workpiece 13 positively charged, and the cathode 9 coaxially installed with the laser beam is connected to the negative pole of the power supply 1 to make the spray liquid The beam is charged “cathodicized” and sprayed coaxially with the laser beam at a certain speed, and the spray speed can be adjusted by the overflow pressure regulating valve 18; the laser light emitted by the laser 2 is focused by the focusing lens 4 on the processing position of the workpiece surface for laser drilling processing, At the same time, the cooling and scouring effect of the sprayed liquid beam on the laser processing area, as well as the electrolysis of the wo...

Description

1. Technical field [0001] The present invention relates to a method for processing small holes, slots, grooves and other structures, in particular to a compound processing method using electrolysis and laser, and to a special processing device for the method. 2. Background technology [0002] Electrolytic processing and laser processing are processing technologies that were only developed in the 1950s and 1960s. Due to their different advantages, they have developed rapidly. They are used in aerospace, weaponry, automobile, electronics, shipbuilding and other manufacturing industries been widely used in. Both have distinct characteristics for the processing of small holes, seams and grooves with a size of 0.25mm to 1.5mm that widely exist in the above fields. Laser processing is a high-energy beam processing method. It uses photons as energy carriers and uses the photothermal effect generated by the high energy density of focused light to remove materials. It has fast proce...
