Milling Cutter Basics

Izinto eziyisisekelo zokusika

Yini i-milling cutter?

Ngokombono wezobuchwepheshe, i-milling cutter iyithuluzi lokusika elisetshenziselwa ukugaya. Iyakwazi ukuphenduka ibe nezinyo elilodwa noma amaningi okusika. Phakathi nenqubo yokugaya, izinyo ngalinye linqamula isabelo somsebenzi ngezikhathi ezithile. Isetshenziswa kakhulu ekwenzeni izindiza, izinyathelo, imigodi, ukwakha izindawo kanye nokusika izingcezu zokusebenza emishinini yokugaya. Izwe eliwumngcingo lakhiwa ehlangothini ukuze lenze i-engeli yokusiza, futhi impilo yalo iphakeme ngenxa ye-engeli yokusika enengqondo. Ingemuva le-pitch milling cutter linezinhlobo ezintathu: umugqa oqondile, ijika kanye nomugqa ogoqayo. Ingemuva elilayini livame ukusetshenziselwa abasiki bokuqeda abanamazinyo amahle. Amajika nama-creases anamandla angcono wamazinyo futhi angakwazi ukumelana nemithwalo esindayo yokusika, futhi avame ukusetshenziselwa abasiki be-coarse-tooth milling.

Yiziphi izisiki ezivamile zokugaya?

I-Cylindrical milling cutter: isetshenziselwa ukwenza imishini yezindiza emishinini yokugaya evundlile. Amazinyo asatshalaliswa kumjikelezo we-milling cutter futhi ahlukaniswe abe amazinyo aqondile namazinyo azungezayo ngokuya ngokuma kwezinyo. Ngokwenani lamazinyo, kunezinhlobo ezimbili zamazinyo amaholo kanye namazinyo amahle. I-Spiral tooth coarse-tooth milling cutter inamazinyo ambalwa, amandla amazinyo aphezulu, isikhala esikhulu se-chip, esilungele umshini onzima; i-fine-tooth milling cutter ifanele ukuqedwa;

I-Face milling cutter: isetshenziselwa imishini yokugaya eqondile, imishini yokugaya ubuso noma imishini yokugaya i-gantry. Ubuso bokuphela kwendiza kanye neziyingi zinamazinyo namazinyo aqinile namazinyo amahle. Isakhiwo sinezinhlobo ezintathu: uhlobo olubalulekile, uhlobo lokufaka kanye nohlobo lwenkomba;

Isigayo sokugcina: sisetshenziselwa umshini wokugaya kanye nezinyathelo ezingaphezulu. Amazinyo akusiyingi nobuso bokugcina. Azikwazi ukuphakelwa isiqondiso se-axial ngesikhathi sokusebenza. Lapho isigayo sokugcina sinezinyo lokugcina elidlula phakathi nendawo, singaphakelwa nge-axially;

Umsiki wokugaya onqenqemeni olunezinhlangothi ezintathu: esetshenziselwa umshini ama-grooves ahlukahlukene kanye nobuso besinyathelo ngamazinyo nhlangothi zombili kanye nesiyingi;

I-Angle milling cutter: isetshenziselwa ukugaya inkatho nge-engeli, kokubili abasiki be-engeli eyodwa kanye ne-double-engeli yokugaya;

I-saw blade milling cutter: isetshenziselwa umshini ama-grooves ajulile futhi isike izingcezu zokusebenza ngamazinyo engeziwe kusiyingi. Ukuze kuncishiswe i-engeli yokungqubuzana komsiki, kukhona ukwehla kwesibili okungu-15'~1° kuzo zombili izinhlangothi. Ngaphezu kwalokho, kukhona abasiki be-keyway milling, abasiki be-dovetail milling, abasiki be-T-slot milling kanye nabasiki abahlukahlukene abakha.

Yiziphi izidingo zempahla yokukhiqiza yengxenye yokusika yesisiki sokugaya?

Izinto ezivamile zokukhiqiza izisiki zokugaya zihlanganisa izinsimbi zamathuluzi esivinini esikhulu, ama-alloys aqinile njenge-tungsten-cobalt nama-alloys aqinile asekelwe ku-titanium-cobalt. Yiqiniso, kukhona ezinye izinto zensimbi ezikhethekile ezingasetshenziswa futhi ukwenza abasiki bokugaya. Imvamisa, lezi zinto zensimbi Zinezimpawu ezilandelayo:

1) Ukusebenza okuhle kwenqubo: ukukhanga, ukucubungula nokulola kulula;

I-2) Ukuqina okuphezulu nokumelana nokugqoka: Ekushiseni okujwayelekile, ingxenye yokusika kufanele ibe nobunzima obanele bokusika ku-workpiece; inokumelana nokugqoka okuphezulu, ithuluzi aligqoki futhi landisa impilo yesevisi;

I-3) Ukumelana nokushisa okuhle: ithuluzi lizokhiqiza ukushisa okukhulu ngesikhathi sokusika, ikakhulukazi lapho isivinini sokusika siphezulu, izinga lokushisa lizoba phezulu kakhulu. Ngakho-ke, impahla yamathuluzi kufanele ibe nokumelana nokushisa okuhle, ngisho namazinga okushisa aphezulu. Ingakwazi ukugcina ubulukhuni obuphezulu futhi inamandla okuqhubeka nokusika. Lolu hlobo lokuqina kwezinga lokushisa eliphezulu lubizwa nangokuthi i-thermosetting noma ubulukhuni obubomvu.

I-4) Amandla aphezulu kanye nokuqina okuhle: Ngesikhathi senqubo yokusika, ithuluzi kufanele lithwale amandla amakhulu omthelela, ngakho-ke impahla yamathuluzi kufanele ibe namandla aphezulu, ngaphandle kwalokho kuyoba lula ukuphuka nokulimala. Njengoba i-milling cutter ingaphansi kokushaqeka nokudlidliza, i-milling cutter materialkufanele futhi ibe nokuqina okuhle, ukuze kungabi lula ukuqopha nokuqopha.

Kwenzekani ngemva kokunqanyulwa komshini wokugaya?

1. Kusukela ekumeni konqenqema lommese, umphetho wommese unomhlophe okhanyayo;

2. Kusukela ekubunjweni kwe-chip, ama-chips abe ama-coarse futhi amise okwe-flake, futhi umbala wama-chips unsomi kanye nomusi ngenxa yokukhuphuka kwezinga lokushisa lama-chips;

3. Inqubo yokugaya ikhiqiza ukundindizela okukhulu kakhulu nomsindo ongajwayelekile;

4. Ubunzima bobuso bomsebenzi wokusebenza bumpofu kakhulu, futhi ubuso bomsebenzi bunamabala akhanyayo anamasikela noma ama-ripples;

5. Lapho ugaya izingxenye zensimbi ezinama-carbide milling cutters, inkungu enkulu yomlilo ivame ukundiza;

6. Izingxenye zensimbi zokugaya ezinama-milling cutter ensimbi anesivinini esikhulu, uma zipholile ngokugcotshwa kwamafutha, zizokhipha intuthu eningi.

Lapho i-milling cutter idluliswa, kufanele imiswe kusenesikhathi ukuze kubhekwe ukuguga kwesisiki sokugaya. Uma ukugqokwa kukuncane, unqenqema lokusika lungasetshenziswa ukugaya unqenqema lokusika bese lusetshenziswa kabusha. Uma isigqoko sisinda, kufanele silolwe ukuvimbela isigayo ukuthi singeqisi. Gqoka
