Izingxenye zemikhono enezindonga ezincane zinezakhiwo nezakhiwo eziyingqayizivele.Ugqinsi lwazo oluncane lwezindonga nokungaqini kahle kwenza ukucutshungulwa kwezingxenye zemikhono enezindonga ezincane kugcwale izinselele.Indlela yokuqinisekisa ukunemba kanye nekhwalithi ngesikhathi sokucutshungulwa kuyinkinga izingxenye onjiniyela be-R&D nochwepheshe okufanele babhekane nazo.Lesi sihloko sizocubungula amaphuzu abalulekile okucubungula izingxenye zemikhono enezindonga ezincane futhi sinikeze ireferensi yokucacisa uhlelo lokucubungula oluphusile.
Okuqukethwe
(1) Ukuguqulwa okubangelwa ukubopha ucezu lokusebenza
(2) Umthelela wenani lokusika ezingxenyeni ezinezindonga ezincane
(3) Khetha ngokunengqondo i-engeli yejiyomethri yethuluzi
(4) Umthelela wokusika uketshezi ezingxenyeni ezinezindonga ezincane
1. Ukuguqulwa okubangelwa ukubopha i-workpiece
Umehluko wobubanzi phakathi kwendilinga yangaphakathi nengaphandle yezingxenye ezinezindonga ezincane kakhulu futhi amandla aphansi.Uma i-clamping force inamandla kakhulu uma ubamba i-chuck, izingxenye ezinezindonga ezincane zizokonakala, okuholela ekuyindilinga okweqile, i-cylindricity kanye ne-coaxiality yezingxenye.Umehluko.Uma i-clamping ingaqinile ngesikhathi sokujika nokugaya, izingxenye zingase zixege futhi zilahlwe.Ngokuvamile, ukuguqulwa kwezingxenye kulawulwa ngokulawula amandla okubamba.Amandla okubamba kufanele abe makhudlwana ngesikhathi sokuguquka futhi abe mancane ngesikhathi sokuguqula nokugaya.Lapho ucubungula izingxenye ezinezindonga ezincane, imikhono engaphambili evulekile noma izinzipho ezithambile ezimise okuwumkhakha zingasetshenziswa ukubopha ucezu lokusebenza.Phakathi nenqubo yokubopha izingxenye, ukwakheka nokwakheka kwezingxenye kuhlukile, futhi ubukhulu nephuzu lesenzo samandla kuhlukile, okungase kuthinte ukunemba komumo wezingxenye.
2.Umphumela wokusika inani ezingxenyeni ezinezindonga ezincane
Ubukhulu bamandla okusika buhlobene eduze nenani lokusika.Inani lokusika emuva, inani lokuphakelayo, kanye nesivinini sokusika yizici ezintathu zenani lokusika.Ukukhetha okunengqondo kwezinto ezintathu kunganciphisa amandla okusika futhi ngaleyo ndlela kunciphise ukuguquguquka.
3. Khetha ngokunengqondo i-engeli yejometri yethuluzi
Ekuphenduleni izingxenye ezinezindonga ezincane, i-engeli yejiyomethri enengqondo yethuluzi ibalulekile kubukhulu bamandla okusika ngesikhathi sokuphenduka, ukuwohloka kokushisa okukhiqizwayo, kanye nekhwalithi encane kakhulu yendawo yokusebenza.Ubukhulu be-engeli ye-rake yethuluzi bunquma ukuwohloka kokusika kanye nobukhali be-engeli ye-rake yethuluzi.I-engeli ye-rake yethuluzi inkulu, i-deformation yokusika nokungqubuzana kuyancishiswa, futhi amandla okusika ayancipha.Kodwa-ke, uma i-engeli ye-rake inkulu kakhulu, i-engeli ye-wedge yethuluzi izoncishiswa, amandla ethuluzi azoba buthakathaka, ukuchithwa kokushisa kwethuluzi kuzoba kubi, futhi ukuguga kuzosheshisa.
4. Umthelela wokusika uketshezi ezingxenyeni ezinezindonga ezincane
Phakathi nenqubo yokuguqula, ngenxa yokusika nokungqubuzana phakathi kwama-chips, ithuluzi kanye ne-workpiece, kukhiqizwa inani elikhulu lokushisa, elidluliselwa ethuluzini, linciphisa ubulukhuni bethuluzi, ukusheshisa ukugqoka kwamathuluzi, nokwandisa indawo. ukuqina kwe-workpiece;idluliselwe ku-workpiece, ibangele ukuguqulwa kokushisa kwe-workpiece.Ukuba khona kokusika ukushisa kuyingozi kakhulu ekuguquleni izingxenye ezinezindonga ezincane.Ukusetshenziswa ngokugcwele koketshezi lokusika phakathi nenqubo yokujika akugcini nje ukunciphisa amandla okusika, kuthuthukisa impilo yamathuluzi, futhi kunciphisa inani lokuma okungaphezulu kwendawo yokusebenza;ngesikhathi esifanayo, i-workpiece ayithinteki ngokusika ukushisa, ukuqinisekisa ubukhulu bokucubungula nokubekezelelana kwejometri kwengxenye.
Amakhono Okwenza we-GPM:
I-GPM inesipiliyoni seminyaka engu-20 ku-CNC machining yezinhlobo ezahlukene zezingxenye ezinembayo.Sisebenze namakhasimende ezimbonini eziningi, okuhlanganisa i-semiconductor, imishini yezokwelapha, njll., futhi sizibophezele ekunikezeni amakhasimende ngekhwalithi ephezulu, izinsizakalo zemishini ezinembile.Samukela uhlelo oluqinile lokuphatha ikhwalithi ukuze siqinisekise ukuthi ingxenye ngayinye ihlangabezana nokulindelwe ngamakhasimende kanye namazinga.
