Abstract
A magnetic grinding method for grinding microhole and microparts features that the microminiature electrodes, microhole, or microslot is ground and polished by the electrode discharge processing method with the grinding magnetic particles. Its advantages include short period, saving material, high precision and reduced pollution.
Description
The present invention relates to technology in electromagnetic processing, refer in particular to the processing method of a kind of micropore and little 's magnetically grinding.
Abrasive polishing method about micropore is divided into following three kinds substantially.
First kind is " the super mirror light of the electrolysis abrasive particle processing method of small diameter tube inner face " of No. 168627, Taiwan patent announcement, its way is in being mixed with the electrolyte of fine free abrasive, pass to Weak current between small diameter tube (positive pole) and electrode tool (negative pole), this electrode tool uses to be around in the nylon nonwoven fabrics of abrasive particle or amine Ethyl formate material webs and does the processing of mirror light around the core electrode and use, mat electrolytic polishing small diameter tube inner face, parallel with it and electrode tool and small diameter tube are given relative the revolution, and axially do relative reciprocating motion, the effect of free abrasive particle in the electrolyte and mechanical mirror light grinds the inner face of small diameter tube.Its major defect is to use nylon nonwoven fabrics, the amine Ethyl formate of having abrasive particle and the electrolyte that is mixed with fine free abrasive, increases cost; Because clad material can take up room, so can't grind micron-scale following micropore, microflute or small diameter tube; Abrasive particle is free state, makes the time of grinding oversize.
Second kind is " the micropore burnishing device " of No. 356435, Taiwan patent announcement, it must use anchor clamps that work piece is arranged and remain in a row shape, the method is not suitable for micropore and microflute, can produce the difficulty especially in contraposition and the clamping, can not make that discharge processing, grinding, welding and fine group are upright directly to mutually combine.
The third is No. 356436, Taiwan patent announcement " polishing pad and working surface grinding method and polishing devices ", it must provide polyurethane, felt or cloth as polishing pad earlier, and must absolutely compress fully with the work package surface, for slim and volume is small and work package that can not compress is just inapplicable, the polishing that generally only limits to semiconductor crystal wafer is used.
The object of the present invention is to provide the processing method of a kind of micropore and little 's magnetically grinding.It is to utilize magnetic abrasive grain, adopts electrode discharge method for processing grinding and polishing microelectrode, micro-inner-hole or microflute, overcomes the drawback of prior art, reach save time, precision is polluted and improved to economical with materials, minimizing purpose.
The object of the present invention is achieved like this: processing method of the present invention comprises the steps:
(1) electrode discharge processing:
At first on discharging processing machine commonly used, install the rotary main shaft of writhing number circle coil additional, utilize the finishing line, the magnetic conductivity electrode is done finishing, process the magnetic conductivity electrode of required shape, diameter and size by discharge.
(2) micropore discharge processing:
The magnetic conductivity electrode pair work package that processes with (one) processing of discharging processes required micropore on work package;
(3) micropore magnetically grinding polishing processing:
The inner face of micropore to above-mentioned (two) processing polishes processing, the magnetically grinding grain that adsorbs right quantity earlier with the magnetic conductivity electrode, the micropore that will adsorb the electrode alignment work package of magnetically grinding grain is again done rotation and up-down vibration, makes this micropore finish magnetically grinding polishing processing.
The processing method of little magnetically grinding is characterized in that: comprise the steps:
(1) electrode discharge processing: on discharging processing machine, install the rotary main shaft of writhing number circle coil additional, utilize the finishing line to be trimmed to required shape and size to little;
(2) little magnetic grinding and polishing light processing: get magnetic element, absorption magnetically grinding grain in its micropore corresponding with little is done rotation and up-down vibration with little after this finishing micropore of aiming at this magnetic element.Finish grinding and polishing to little.This little comprises microelectrode.
Major advantage of the present invention is:
1, do not need contraposition, can on same benchmark, process micropore and polishing, greatly improve machining accuracy.
2, do not need clad material, significantly reduce cost electrode.
3, do not need chemical electrolysis liquid, reduce environmental pollution.
4, the shape of magnetic abrasive grain composition can change with the micropore that grinds, and is applicable to the micropore, microflute or the small diameter tube that grind micron-scale.
Further specify below in conjunction with preferred embodiment and accompanying drawing.

Fig. 2 is a micropore discharge processing schematic diagram of the present invention;
Fig. 3 is a micropore magnetically grinding polishing schematic diagram of the present invention;
Fig. 4 is an electrode magnetically grinding polishing schematic diagram of the present invention.
Consult Fig. 1-Fig. 4, the processing method of micropore of the present invention and little 's magnetically grinding comprises the steps:
(1) electrode discharge processing:
At first on discharging processing machine commonly used, install the rotary main shaft of writhing number circle coil additional, utilize finishing line 2, often select brass wire for use, the magnetic conductivity electrode is done finishing, process required shape, diameter and big or small magnetic conductivity electrode 1 by discharge, as shown in Figure 1.
(2) micropore discharge processing:
The 1 pair of work package 5 of magnetic conductivity electrode that processes with (one) processing of discharging processes required micropore 7, as shown in Figure 2 on work package 5.
(3) micropore magnetically grinding polishing processing:
The inner face of micropore 7 to above-mentioned (two) processing polishes processing, adsorb the magnetically grinding grain 4 of right quantity with magnetic conductivity electrode 1 earlier, the micropore 7 that will adsorb the electrode 6 alignment work parts 5 of magnetically grinding grain 4 is again done rotation and up-down vibration, make this micropore 7 finish magnetically grinding polishing processing, as shown in Figure 3.
Above-mentioned step (two) micropore discharge processing and step (three) micropore magnetically grinding polishing processing are to process on same benchmark, do not need contraposition, greatly save man-hour, and improve machining accuracy.
Processing method of the present invention, the same small workpiece of grinding and polishing that is fit to, for example this small workpiece is the microelectrode 1 ' that needs polishing, comprise the steps: to process with the electrode discharge of step () earlier, on discharging processing machine, install the rotary main shaft of writhing number circle coil additional, utilize finishing line 2, microelectrode 1 ' is trimmed to required shape and size; (2) little magnetically grinding polishing processing: get magnetic element 3, absorption magnetically grinding grains 4 in its micropore corresponding 9 with microelectrode 1 ', microelectrode after this finishing 1 ' is aimed at the micropore 9 of this magnetic element 3 and done rotation and up-down vibration, finish grinding and polishing microelectrode 1 '.As shown in Figure 4.
