Iinkonzo zoMatshini ze-CNC

Siyiqonda njani i-EDM?

I-Electric discharge machining (EDM) yinkqubo entsha esebenzisa amandla ombane kunye namandla okushisa ukuze kuqhutywe, okubizwa ngokuba yi-discharge machining. Umahluko phakathi kwe-EDM kunye nokusika ngokubanzi kukuba isixhobo kunye ne-workpiece ayidibanisi ngexesha le-EDM, kodwa ixhomekeke kwi-pulsed spark discharge eyenziwa ngokuqhubekayo phakathi kwesixhobo kunye ne-workpiece, kwaye isebenzise ubushushu obuphezulu bendawo kunye nesantya esiphezulu esiveliswa ngexesha lokukhupha ngokuthe ngcembe. ukhukulise izinto zentsimbi.

Iimpawu eziphambili ze-machining yokukhutshwa kombane

1. Ukwazi ukucubungula izinto kunye nezixhobo zokusebenza ezinobumba obunzima obunzima ukusika ngeendlela eziqhelekileyo zokusika;

2. Akukho mandla okusika ngexesha lomatshini;

3. Musa ukuvelisa iziphene ezifana neebhura kunye neempawu zeemela kunye neegrooves;

4. Isixhobo se-electrode yesixhobo akufuneki ukuba sibe nzima kunomsebenzi wokusebenza;

5. Ukusebenzisa ngokuthe ngqo ukusetyenzwa kwamandla ombane ukuze kube lula ukuzenzela;

6. Umphezulu ufumana i-metamorphic layer emva kokucubungula, efuna ukususwa ngakumbi kwizicelo ezithile;

7. Ukucocwa kolwelo olusebenzayo kunye nokunyangwa kongcoliseko lomsi oluveliswa ngexesha lokulungiswa kuyingxaki.

Yintoni enokuyenza?

1. Ukusetyenzwa kokungunda kunye neenxalenye ezinemingxuma entsonkothileyo kunye nemingxuma; 2. Ukucutshungulwa kwezixhobo ezahlukeneyo eziqinileyo kunye ne-brittle ezifana ne-alloys eqinile kunye nentsimbi ecinyiweyo; 3. Ukucutshungulwa kwemingxuma enzulu necolekileyo, imingxuma engaqhelekanga, imijelo enzulu, imithungo emxinwa, kunye nokusika amashiti amancinci; 4. Inkqubo yezixhobo ezahlukeneyo zokubumba, iitemplates, iigeji zeringi zentambo, kunye nezinye izixhobo kunye nezixhobo zokulinganisa.

Ngokwesiqhelo Inokwenziwa Ngokuchaneka

Ukuchaneka komgangatho wokugqobhoza kuxhomekeke kubungakanani besixhobo se-electrode kunye nesithuba sokukhutshwa kwentlantsi ukuqinisekisa ukuba ubungakanani beprofayili yecandelo lomnqamlezo we-electrode buncitshiswe ngokulinganayo ngumsantsa wokucubungula kunobungakanani bomngxuma womatshini ochaziweyo, ukuchaneka komda yinqanaba elinye eliphezulu kunomsebenzi, ngokuqhelekileyo alikho ngaphantsi kwenqanaba le-IT7, kwaye ixabiso lomphezulu woburhabaxa lincinci kunomsebenzi. Ukuthe tye, ukucaba kunye nokuhambelana akukho mkhulu kune-0.01mm kubude be-100 mm.

Indawo yesicelo

Ukukhutshwa kombane kusetyenziselwa ikakhulu ukwenza imingxunya kunye nemingxuma kwimveliso yokubumba, kwaye ibe yindlela ehamba phambili yokucubungula kwishishini lemveliso yokubumba, ukukhuthaza inkqubela phambili yezobuchwepheshe kushishino lokubumba. Xa inani leengxenye ze-EDM lingaphantsi kwe-3000, kunengqiqo ngakumbi ngokwezoqoqosho kuneendawo ezifakelwe isitampu.

Ngokweempawu kunye neenjongo zentshukumo ehambelanayo phakathi kwezixhobo kunye nezixhobo zokusebenza ngexesha lenkqubo, ukukhutshwa kombane kunokwahlulwa ngokulinganayo: ukukhupha umbane ukwenza i-machining, ukukhupha umbane wokusika, ukukhupha umbane wokugaya, ukukhupha umbane, ukukhutshwa kombane metallic electric discharge machining, kunye nokukhutshwa kombane ukomeleza umphezulu.

Ukwenziwa kwe-EDM

Le ndlela ibandakanya ukukopa imilo kunye nobukhulu be-electrode yomsebenzi kwi-workpiece ngokusebenzisa intshukumo yokutya ye-electrode yesixhobo ngokunxulumene nomsebenzi, ngokwenza oko ukuvelisa iindawo ezifunekayo.

Ukukhutshwa kombane ukusika oomatshini bokusika:

Le ndlela isebenzisa iingcingo zentsimbi ezihamba kakuhle njengesixhobo se-electrode ukwenza i-pulse discharge cutting ngokwendlela echazwe kwangaphambili. Ngokwesantya sokuhamba kwe-electrode yensimbi, inokwahlulwa ibe yi-high-speed wire cut and low-speed wire cut.
