Ukusetshenziswa Okulungile Kwe-End Mill

Ukusetshenziswa okulungile kwe-end mill

Lapho kugaywa ama-workpieces ayinkimbinkimbi esikhungweni sokugaywa kwemishini, lezi zinkinga ezilandelayo kufanele zinakwe lapho kusetshenziswa isinqamuleli sokulawula izinombolo sokuphela kokugaya:

1. I-end milling cutter esetshenziswa esikhungweni somshini wokuhlanganisa we-end milling cutter kakhulu isebenzisa imodi yesethi yokuqinisa i-spring clamp, esesimweni se-cantilever uma isetshenziswa. Enqubweni yokugaya, ngezinye izikhathi i-end milling cutter ingase iphume kancane kancane kumphathi wamathuluzi, noma ihlehle ngokuphelele, okuholela esimweni sokuchithwa kwe-workpiece. Ngokuvamile, isizathu siwukuthi kukhona ifilimu kawoyela phakathi kwembobo yangaphakathi yesibambi samathuluzi kanye nobubanzi obungaphandle be-end milling cutter shank, okuholela ekubambeni kwamandla anganele. I-end milling cutter ngokuvamile igcotshwa ngamafutha e-antirust lapho iphuma efektri. Uma amafutha okusika angancibiliki emanzini asetshenziswa ngesikhathi sokusika, imbobo yangaphakathi yesibambi sokusika izophinde ihlanganiswe nongqimba lwenkungu njengefilimu yamafutha. Uma kukhona ifilimu yamafutha esibanjeni kanye nesibambi sokusika, kunzima kumnikazi wokusika ukuthi abambe isibambo ngokuqinile, futhi i-milling cutter izoba lula ukuyikhulula futhi iwe ngesikhathi sokucubungula. Ngakho-ke, ngaphambi kokuba i-end milling cutter iboshwe, isibambo se-end milling cutter kanye nembobo yangaphakathi ye-cutter clamp kufanele ihlanzwe ngoketshezi lokuhlanza bese iboshiwe ngemva kokumiswa. Lapho ububanzi bomshini wokugcina bukhulu, ngisho noma isibambo kanye ne-clamp kuhlanzekile, umsiki angase awe. Kulokhu, isibambo esine-notch eyisicaba kanye nendlela yokukhiya ohlangothini oluhambisanayo kufanele kukhethwe.

2. Ukudlidliza kwesigayo sokuphela

Ngenxa yegebe elincane phakathi kwesisiki sokuphela sokugaya kanye ne-cutter clamp, umsiki angase adlidlize phakathi nenqubo yomshini. Ukudlidliza kuzokwenza inani lokusika lomphetho oyindilinga we-milling cutter ekugcineni lingalingani, futhi ukunwetshwa kokusika kukhulu kunenani elibekiwe lokuqala, elizothinta ukunemba komshini kanye nempilo yesevisi yomsiki. Kodwa-ke, lapho ububanzi be-groove buncane kakhulu, ithuluzi lingadlidliza ngenhloso, futhi ububanzi be-groove obudingekayo bungatholakala ngokwandisa ukunwetshwa kokusika, kodwa kulokhu, ubukhulu be-amplitude yomshini wokugcina kufanele bulinganiselwe ngaphansi kwe-0.02mm, ngaphandle kwalokho ukusika okuzinzile akukwazi ukwenziwa. Okuncane ukudlidliza kwe-milling cutter kuba ngcono. Lapho ukudlidliza kwethuluzi kwenzeka, isivinini sokusika kanye nesivinini sokuphakela kufanele sincishiswe. Uma kusekhona ukudlidliza okukhulu ngemva kokuba kokubili kwehliswe ngo-40%, inani lamathuluzi okudla okulula kufanele lincishiswe. Uma i-resonance ivela kusistimu yomshini, ingase ibangelwe izici ezifana nesivinini sokusika ngokweqile, ukungaqini ngokwanele kwesistimu yamathuluzi ngenxa yokuchezuka kwesivinini sokuphakelayo, amandla okubamba anganele wengcezu yokusebenza, kanye nokuma kocezu lokusebenza noma indlela yokubopha. Ngalesi sikhathi, kuyadingeka ukulungisa inani lokusika futhi ukwandise inani lokusika.

Ukuqina kwesistimu yamathuluzi kanye nokuthuthukiswa kwesivinini sokuphakelayo.

3. Qeda ukusika kwe-end milling cutter

Ku-NC Milling of die cavity, lapho iphuzu elizosikwa liyingxenye ye-concave noma i-cavity ejulile, kuyadingeka ukunweba ukunwetshwa komsiki wokugaya ekugcineni. Uma kusetshenziswa isigayo sokuphela konqenqema olude, kulula ukukhiqiza ukudlidliza futhi kubangele ukulimala kwamathuluzi ngenxa yokuchezuka kwayo okukhulu. Ngakho-ke, ohlelweni lokugaya, uma kuphela umkhawulo wokusika eduze nokuphela kwethuluzi kuyadingeka ukuba ubambe iqhaza ekusikeni, kungcono ukhethe umshini omfishane we-shank end mill enobude obude bethuluzi. Lapho isigayo esikhulu sokuphela kobubanzi sisetshenziswa kuthuluzi lomshini we-CNC ovundlile ukucubungula ama-workpieces, ngenxa yokuguqulwa okukhulu okubangelwa isisindo esifile sethuluzi, ukunakekelwa okwengeziwe kufanele kukhokhwe ezinkingeni ezingenzeka kalula ekusikeni kokugcina. Lapho isigayo sokuphela konqenqema ende kufanele sisetshenziswe, isivinini sokusika kanye nesivinini sokuphakela sidinga ukuncishiswa kakhulu.

4. Ukukhethwa kwemingcele yokusika

Ukukhethwa kwejubane lokusika ikakhulukazi kuncike ezintweni ze-workpiece okufanele zicutshungulwe; ukukhethwa kwejubane lokuphakelayo ikakhulukazi kuncike ezintweni ze-workpiece okufanele zicutshungulwe kanye nobubanzi bomshini wokuphela. Amasampula wamathuluzi avela kwabanye abakhiqizi bamathuluzi angaphandle anamathiselwe nethebula lokukhetha ipharamitha yokusika ithuluzi ukuze kusetshenziswe inkomba. Kodwa-ke, ukukhethwa kwemingcele yokusika kuthintwa yizici eziningi ezifana nethuluzi lomshini, uhlelo lwamathuluzi, ukuma kwe-workpiece okufanele icutshungulwe kanye nendlela yokubopha. Ijubane lokusika kanye nesivinini sokudla kufanele kulungiswe ngokuya ngesimo sangempela. Uma impilo yamathuluzi ibalulekile, isivinini sokusika kanye nesivinini sokuphakela singancishiswa kahle; lapho i-chip ingekho esimweni esihle, isivinini sokusika singandiswa ngendlela efanele.

5. Ukukhethwa kwemodi yokusika

Ukusetshenziswa kwe-down milling kunenzuzo ukuvimbela ukulimala kwe-blade futhi kuthuthukise impilo yamathuluzi. Kodwa-ke, amaphuzu amabili adinga ukuqashelwa: ① uma amathuluzi omshini ajwayelekile asetshenziselwa ukukhanda, kuyadingeka ukususa igebe phakathi kwendlela yokudla; ② uma kukhona ifilimu ye-oxide noma olunye ungqimba oluqinile olwakhiwe ngokusakazwa nokubunjwa kwenqubo phezu kwendawo yokusebenza, kuyalulekwa ukuthi kusetshenziswe ukugaya okuhlanekezelwe.

6. Ukusetshenziswa kwezigayo zokugcina ze-carbide

Imishini yokuphela kwensimbi enesivinini esiphezulu inezinhlobonhlobo zokusetshenziswa kanye nezidingo. Ngisho noma izimo zokusika zingakhethiwe kahle, ngeke kube nezinkinga eziningi kakhulu. Nakuba i-carbide end milling cutter inokumelana okuhle kokugqoka ekusikeni kwesivinini esikhulu, uhla lwalo lokusebenza alubanzi njengalo lwe-high-speed steel end milling cutter, futhi izimo zokusika kufanele zihlangabezane ngokuqinile nezidingo zokusetshenziswa komsiki.
