Ekucutshungulweni kokugaya, indlela yokukhetha okufaneleISIGAYO SOKUPHELA SE-CARBIDEfuthi wahlulele ukuguguleka komshini wokusika ngokuhamba kwesikhathi ngeke nje kuthuthukise ukusebenza kahle kokucubungula, kodwa futhi kunciphise nezindleko zokucubungula.
Izidingo Eziyisisekelo Zezinto Zokwenza I-End Mill:
1. Ubulukhuni obuphezulu kanye nokumelana nokuguguleka
Uma izinga lokushisa elijwayelekile liphezulu, ingxenye yokusika yezinto kufanele ibe nobunzima obanele bokusikwa endaweni yokusebenza; uma ingagugi kakhulu, ithuluzi ngeke liguge futhi lenze isikhathi eside sokuphila.
2. Ukumelana okuhle nokushisa
Ithuluzi lizokhiqiza ukushisa okuningi ngesikhathi senqubo yokusika, ikakhulukazi uma isivinini sokusika siphezulu, izinga lokushisa lizoba phezulu kakhulu.
Ngakho-ke, izinto zamathuluzi kufanele zibe nokumelana okuhle nokushisa, okungagcina ubulukhuni obuphezulu ngisho noma kushisa kakhulu, futhi kube nokumelana okuhle nokushisa. Amandla okuqhubeka nokusika, lesi sici sinobulukhuni obuphezulu bokushisa, esaziwa nangokuthi ubulukhuni obushisayo noma ubulukhuni obubomvu.
3. Amandla aphezulu nokuqina okuhle
Enqubweni yokusika, ithuluzi kufanele lithwale amandla amakhulu okushaya, ngakho-ke izinto zamathuluzi kumele zibe namandla aphezulu, ngaphandle kwalokho kulula ukuphuka nokulimaza. Njengobaumsiki wokugayauma ingase ithinteke futhi idlidlize, izinto zomshini wokusika kufanele zibe nokuqina okuhle, ukuze kungabi lula ukuziqhekeza nokuzephula.
Izimbangela zokuguga kwe-milling cutter
Izizathu zokuguguleka kweizigayo zokugcinaziyinkimbinkimbi kakhulu, kodwa zingahlukaniswa cishe noma ngokuyinhloko zibe izigaba ezimbili:
1. Ukuguguleka kwemishini
Ukuguguleka okubangelwa ukungqubuzana okukhulu phakathi kwe-chip nobuso be-rake yethuluzi, ukuguquguquka okunwebekayo kobuso obusetshenzisiwe bento yokusebenza kanye nohlangothi lwethuluzi kubizwa ngokuthi ukuguguleka komshini. Uma izinga lokushisa lokusika lingekho phezulu kakhulu, ukuguguleka komshini okubangelwa yilokhu kungqubuzana kuyimbangela eyinhloko yokuguguleka kwethuluzi.
2. Ukuguga kokushisa
Ngesikhathi sokusika, ngenxa yokuguquka okukhulu kwepulasitiki kwensimbi kanye nokushisa kokusika okubangelwa ukungqubuzana, ukuguguleka okubangelwa ukuncipha kobulukhuni be-blade kanye nokulahlekelwa ukusebenza kokusika kubizwa ngokuthi ukuguguleka kokushisa.
Ngaphezu kwezinhlobo ezimbili zokugqoka ezingenhla, kunezinhlobo ezilandelayo zokugqoka:
Ngaphansi kokushisa okuphezulu kanye nokucindezela okuphezulu, kuzoba nokuhlangana phakathi kwethuluzi nezinto zokusebenza, futhi ingxenye yezinto zamathuluzi izothathwa yizicucu, okubangela ukuthi ithuluzi liboshwe futhi liguge.
Emazingeni okushisa aphezulu, ezinye izinto ezisetshenziswayo (njenge-tungsten, i-cobalt, i-titanium, njll.) zizosakazeka ziye ezintweni zokusebenza, ngaleyo ndlela zishintshe ukwakheka kwamakhemikhali kwengqimba engaphezulu yengxenye yokusika yethuluzi, futhi zinciphise amandla nokumelana nokuguguleka kwethuluzi, ukuze ithuluzi likhiqize ukuguguleka kokusabalala.
Kumathuluzi ensimbi asheshayo, emazingeni okushisa aphezulu okusika, isakhiwo se-metallographic sobuso bethuluzi sizoshintsha, sinciphise ubulukhuni kanye nokumelana nokuguguleka, futhi kuzokwenzeka ukuguguleka kokushintsha kwesigaba. Izinyo ngalinye lomshini wokusika liyisike esiqhubekayo ngezikhathi ezithile. Izinga lokushisa lezinyo liyahlukahluka kakhulu kusukela ekushayweni okungasebenzi kuya ekusikeni. Kungashiwo ukuthi isikhathi ngasinye lapho lingena ekusikeni, libhekana nokushaqeka kokushisa. Amathuluzi e-Carbide, ngaphansi kokushaqeka kokushisa, azodala ukucindezeleka okukhulu ngaphakathi kwe-blade, futhi abangele ukuqhekeka, okuholela ekuqhekekeni kokushisa kanye nokuguguleka kwethuluzi. Njengoba umshini wokusika usika ngezikhathi ezithile, izinga lokushisa lokusika aliphezulu njengalelo lokujika, futhi imbangela eyinhloko yokuguguleka kwamathuluzi ngokuvamile ukuguguleka komshini okubangelwa ukungqubuzana komshini.
Ungakubona kanjani ukuguguleka kwamathuluzi?
1. Okokuqala, yahlulela ukuthi igugile noma cha ngesikhathi sokucubungula. Ikakhulukazi enkambisweni yokusika, lalela umsindo. Kungazelelwe, umsindo wethuluzi ngesikhathi sokucubungula awuyona into evamile yokusika. Yiqiniso, lokhu kudinga ukuqongelela ulwazi.
2. Bheka ukucubungula. Uma kukhona izinhlansi ezingajwayelekile ngezikhathi ezithile ngesikhathi sokucubungula, kusho ukuthi ithuluzi seligugile, futhi ithuluzi lingashintshwa ngokuhamba kwesikhathi ngokuya ngokuphila okuvamile kwethuluzi.
3. Bheka umbala wemicu yensimbi. Umbala wemicu yensimbi uyashintsha, okubonisa ukuthi izinga lokushisa lokucubungula lishintshile, okungaba ukuguguleka kwamathuluzi.
4. Uma sibheka ukuma kwezinhlaka zensimbi, kunezimo ezinamazinyo ezinhlangothini zombili zezinhlaka zensimbi, izinhlaka zensimbi zigobile ngendlela engavamile, futhi izinhlaka zensimbi ziba zincane, okusobala ukuthi akuyona umuzwa wokusikwa okuvamile, okufakazela ukuthi ithuluzi seligqokiwe.
5. Uma ubheka ubuso bento yokusebenza, kunezinhlayiya ezikhanyayo, kodwa ubulukhuni nosayizi akukashintshi kakhulu, empeleni okuyithuluzi eliye lagqokwa.
6. Uma silalele umsindo, ukudlidliza komshini kuyaqina, futhi ithuluzi lizokhipha umsindo ongajwayelekile uma ithuluzi lingasheshi. Ngalesi sikhathi, kufanele sinake ukugwema “ukunamathela kommese”, okuzobangela ukuthi umsebenzi ulahlwe.
7. Bheka umthwalo wamathuluzi omshini. Uma kukhona ushintsho olukhulu oluqhubekayo, ithuluzi lingase ligqokwe.
8. Uma ithuluzi lisikiwe, umsebenzi uba nama-burrs amakhulu, ubulukhuni buyancishiswa, usayizi womsebenzi uyashintsha kanye nezinye izinto ezisobala nazo ziyizindlela zokunquma ukuguguleka kwamathuluzi.
Ngamafuphi, ukubona, ukuzwa, nokuthinta, uma nje ungafingqa iphuzu elilodwa, ungahlulela ukuthi ithuluzi ligugile noma cha.
