Zifundise amakhono ayingqayizivele inkosi engawadlulisi, indlela yokusebenzisa ulwazi olusebhokisini le-blade ukuze ukhethe i-blade efanele

Ulwazi olubaluleke kakhulu ebhokisini le-blade yipharamitha yokusika, ebizwa nangokuthi izakhi ezintathu zokusika, ezakhiweV_c=***m/min,f_n=***mm/r,a_p=**mm ebhokisini. Le datha iyidatha yasetiyetha etholwe ilabhorethri, engasinikeza inani lereferensi. Nokho, ukuhlela nokucubungula kwangempela ngokuvamile kudinga isivininiS=**, okuphakelayof=**, kanye nenani lokusika, ngakho-ke ungayiguqula kanjani idatha esebhokisini ibe yidatha esiyidingayo?

Isivinini se-spindle

okuyisivinini sokuphotha ngokuvamile esidinga ukucatshangelwa uma senza izinhlelo, okubhekisela kujubane lokujikeleza ngomzuzu (rpm) we-chuck kanye nocezu lokusebenza.D_myi-diameter ye-workpiece ngemva kokusika, futhiV_cibhekisela ebangeni lejubane lokusika ebhokisini. Ngale fomula kanye nesivinini somugqa womhlahlandlela womkhiqizi, singakwazi ukubala isivinini sethiyori.

Ijubane eliphezulu lethuluzi lomshini, liphakamisa ukusebenza kahle kokusika, nokusebenza kahle kuyinzuzo. Ngakho-ke, kuyadingeka ukucabangela ngokugcwele izimo zokusebenza kanye nesivinini somugqa, futhi ukwandise isivinini ngangokunokwenzeka ukusika.

Ngaphezu kwalokho, ukukhetha kwejubane kufanele kunqunywe ngokusho kwamathuluzi okusika wezinto ezahlukene. Isibonelo, uma ucubungula izingxenye zensimbi ngensimbi enesivinini esikhulu, ukuhwalala kuba ngcono uma ijubane liphansi, kuyilapho ukugoqa kuba ngcono uma isivinini siphezulu kumathuluzi e-carbide enosimende. Ngaphezu kwalokho, lapho kucutshungulwa ama-shaft azacile noma izingxenye ezinezindonga ezincane, ukunakwa kufanele kukhokhwe ekulungiseni isivinini ukuze kugwenywe indawo yokuzwakala kwengxenye, ukuze kuvinjelwe imigqa yokudlidliza ukuthi ingathinti ukuhwalala komhlaba.

Ukusika isivinini Vc

V_cisivinini sokusika, esichazwa njengomkhiqizo wobubanzi, u-π kanye nesivinini sokuphotha, futhi sibhekisela kwisivinini esingaphezulu lapho ithuluzi lihamba khona endaweni yokusebenza. Ngakho-ke, kungabonakala kufomula ukuthi lapho ububanzi be-workpiece buhlukile, ijubane lokusika lihlukile. Ubukhulu be-diameter, bukhuphuka isivinini sokusika.

Ngokuvamile, ngaphandle kokucabangela ukugqoka kwamathuluzi, isivinini sokusika singanyuswa ngokufanele, esingathuthukisa ukusebenza kahle kokukhiqiza futhi sisize ukuthuthukisa ikhwalithi yendawo yokusebenza.

Kodwa isivinini sokusika siyisici esisodwa esibaluleke kakhulu esithinta ukugqokwa kwamathuluzi. Uma isivinini sokusika siphezulu kakhulu, sizoholela kukhwalithi ephansi yezingxenye ngenxa yokugqoka kwe-flank, ukugqoka kwe-crater okusheshayo, ukusebenza kahle kokukhiqiza okuphansi nokunye.

Ngakho-ke, ngemva kokucabangela ukuthi ijubane lokusika liyisici esibaluleke kakhulu esisodwa esithinta ubuso be-workpiece, indlela yokunquma isivinini sokusika esifanele ngokuvamile singachazwa ngesithombe esilandelayo.

Isivinini sokuphakelayof_n

f_nisilinganiso sokuphakelayo, esisho ukugudluzwa ngakunye kwethuluzi elihlobene nocezu lokusebenza oluzungezayo. Okuphakelayo kuzothinta ukwakheka kwe-iron filings, okuholela ekuqhekekeni kwe-chip, ukugoqa, njll.

Mayelana nokuthinta impilo yamathuluzi, uma izinga lokuphakela lincane kakhulu, impilo yamathuluzi yokuguga kweflank izoncishiswa kakhulu. Izinga lokuphakelayo likhulu kakhulu, izinga lokushisa lokusika liyakhuphuka, nokugqoka kwe-flank nakho kuyanda, kodwa umthelela empilweni yamathuluzi mncane kunalowo wejubane lokusika.

Ukujula kokusikaa_p

a_pukujula kokusika, okuyilokho esivame ukukusho, inani lokusika, elibhekisela emehlukweni phakathi kwendawo engacutshungulwanga kanye nendawo ecutshunguliwe.

Uma ukujula kokusika kukuncane kakhulu, kuzodala imihuzuko, kusike ungqimba oluqinile lwe-workpiece, futhi kufinyeze impilo yamathuluzi. Lapho ingaphezulu le-workpiece linesendlalelo esiqinile (okungukuthi, isikhumba esimnyama ebusweni), ukujula kokusika kufanele kukhethwe kukhulu ngangokunokwenzeka ngaphakathi kwebanga elivumelekile lamandla wethuluzi lomshini, ukuze ugweme ichopho ithuluzi lisika kuphela ungqimba oluqinile lwe-workpiece, okuholela ekugugeni okungavamile noma ngisho nokulimala ichopho lethuluzi.

Ngaphezu kwalokho, i-YBG205 esebhokisini le-blade ibhekisela ebangeni lamathuluzi. Izinto zokusebenza ezihambisana namabanga amathuluzi enkampani ngayinye zihlukile. Ngakho-ke, uma ufuna ukunquma ibanga lethuluzi elifanele impahla yakho yokusebenza, udinga ukubonana nencwajana yesampula yenkampani ehambisanayo, futhi ngeke ngiyethule ngokuningiliziwe lapha.
