Ukusikwa kwensimbi kuyinqubo yokukhiqiza esusa izinto lapho ingxenye yokusebenza iphendulwa ngesivinini esiphezulu kuyilapho ithuluzi lokusika elinephoyinti elilodwa lingena engxenyeni ukuze lisuse into. Umphumela uba yingxenye enokulingana kokujikeleza — ama-shaft, ama-bushing, ama-sleeve, ama-flange, ama-adapter, izinto zokuxhuma ezinemicu kanye nezinye izingxenye zensimbi ezisikiwe eziningi ezisetshenziswa cishe kuyo yonke imboni.

Nakuba ama-lathe abelokhu ebumba insimbi amakhulu eminyaka, i-CNC turning yesimanje (computer numerical control) isishintshe le nqubo. Esikhundleni sokuthi umsebenzisi osebenza ngesandla ahambise ithuluzi ngesandla, i-lathe ye-CNC ilandela indlela ye-G-code ehlelwe kusengaphambili. Lokhu kusho ukuthi insizakalo efanayo ye-CNC turning ingaphinda imifanekiso eyinkimbinkimbi, igcine ukunemba okuqinile kufika ku-±0.01 mm, futhi ikhiqize amakhulu noma izinkulungwane zezingxenye ezishintshiwe ezifanayo ngaphandle komehluko phakathi kwengxenye yokuqala neyokugcina ephuma emshinini.

Ukushintshwa kwensimbi ngokuvamile kuhlotshaniswa neminye imisebenzi ehlobene eyenziwa emshinini ofanayo — ukubhoboza, ukukhulisa imbobo, ukwenza ama-knurl, ukugunda imigqa, ukusika, ukubhekana nobuso, ukwenza intambo kanye nokushintshwa kwe-contour. Esikhungweni sokushintsha se-CNC esinamathuluzi aphilayo, ukusethwa okukodwa kungaphinda kugaye izindawo eziyisicaba, kubhoboze izimbobo eziphambanayo futhi kusike ama-keyway, yingakho abathengi abaningi manje bebiza inqubo yonke ngokuthi i-CNC turning-milling esikhundleni sokushintsha kwendabuko.

Wonke umsebenzi wokushintsha we-CNC ulandela ukulandelana okufanayo okuyisisekelo, kungakhathaliseki ukuthi iyiphi into noma i-geometry yengxenye:

— insimbi eluhlaza, i-forging noma i-casting ibanjwa ku-chuck, collet noma faceplate. Emishaftini emide phakathi kwama-centers, i-tailstock ne-steady rest kusekela ingxenye ukuvimbela ukuphambuka.

— i-spindle izungezisa ingxenye yokusebenza ngesivinini esibaliwe sendawo (SFM / m/min) esihambisana nempahla kanye nezinga le-insert.

— i-carbide, cermet, ceramic noma i-CBN insert iphakelwa emaceleni e-X ne-Z ukuze isuse impahla ngendlela yama-chips noma i-swarf.

— ukubhoboza, ukufaka intambo, ukugroova, ukuknurla noma ukugaya nge-live-tool kuyengezwa njengoba kudingwa umdwebo.

— ingxenye eqediwe iyahlukaniswa bese ihlolwa ngokumelene nomdwebo ngezilinganisi, ama-micrometer, ama-pin gauge, i-CMM noma izihloli zokukhahlela kwendawo.

Ngenxa yokuthi ukuphenduka kusebenza kahle kakhulu ekususeni impahla ku-diameter yangaphandle yengxenye ejikelezayo, ngokuvamile kwenziwa ngemuva kwenqubo yokuqala njengokushaya, ukusakaza, ukusaha noma ukukhipha. Ukuphenduka kuvame kakhulu ukuba yisinyathelo sokugcina sokuqedela — umsebenzi oletha ingxenye ezilinganisweni zayo zokugcina, ukuqedwa kwendawo kanye nokubekezelelana kwejiyometri.

Isitolo esisebenza ngobuchwepheshe sokushintsha se-CNC kufanele sikwazi ukusebenza nezinhlobonhlobo zensimbi ezinensimbi kanye nezingenayo insimbi. E-Shengmaisi Hardware, izikhungo zethu zokushintsha zihlala zilungiselelwe izinto ezilandelayo:

Ukukhethwa kwezinto ezisetshenziswayo kuthinta ngqo isikhathi sokusebenza kwethuluzi, amapharamitha okusika, ukuqedwa kwendawo kanye nezindleko zengxenye yokugcina. Uma usithumela umdwebo, onjiniyela bethu babuyekeza into ebekiwe kanye nokubekezelelana kuqala — ngoba izinga elifanele le-insert kanye nezinga lokudla esigabeni sokusho yikho okuvimbela izinkinga zekhwalithi kanye nokumangala kwentengo kamuva.

Esikhungweni sesimanje sokushintsha nge-CNC, umshini owodwa ungasebenza imisebenzi eminingana ekubambeni okukodwa. Izici zezingxenye ezishintshiwe ezicelwa kakhulu zihlanganisa:

— ukulinganisa indawo yokugcina yenduku ukusungula ireferensi enguziro.

— ukunciphisa ububanzi bangaphandle bube yisilinganiso esithile.

— izikhala, imigodi ye-O-ring, imigodi yendandatho yokubamba kanye nokusika.

— amaphethini okubamba edayimane noma aqondile ezibambeni, kuma-knob nakuma-fastener.

— imigodi ehlukile, izindawo eziyisicaba, izikhala kanye nemibuthano yamabhawudi okwenziwa ngaphandle kokusetha okwesibili.

Abathengi bayaqhubeka nokubuya kumasevisi okuphenduka e-CNC ngesizathu esihle. Uma kuqhathaniswa nokubunjwa, ukushaya, ukubunjwa kwe-investimenti noma ukuphrinta kwe-3D, izingxenye eziphenduliwe zinikeza inhlanganisela yezinzuzo okunzima ukuyifanisa:

Ama-CNC lathe esimanje avamise ukugcina u-±0.01 mm futhi angafinyelela ku-±0.005 mm ezingxenyeni ezigayiwe ngokunemba. Leli zinga lokuphindaphinda libalulekile ezingxenyeni ezithwala amabheringi, ebusweni obuvalayo nasezindaweni ezihlangana kuzo.

Ngokwezinga elifanele le-insert kanye ne-wiper geometry, izindawo ezisetshenzisiwe zingafinyelela ku-Ra 0.8 µm noma ngcono ngaphandle kokugaya kwesibili — kunciphisa noma kuqede ngokuphelele izinyathelo zokupholisha, ukuhona noma ukugaya.

Ukusonta kuyinqubo yokususa, kodwa imfucuza ilinganiselwe kuma-metal chips aqoqwayo, aboshwe futhi agaywe kabusha. Ukusetshenziswa kwezinto okuphelele kuseduze kakhulu nengxenye eqediwe kunokubunjwa okuseduze noma ukushaya, ikakhulukazi ekukhiqizeni okusezingeni eliphansi kuya kweliphakathi.

Uma uhlelo selufakazelwe, ishopu yokushaya ye-CNC ingaqalisa umsebenzi ngezinsuku kunamasonto. Azikho izindleko eziqinile zamathuluzi okufanele zikhokhelwe, okwenza ukusonta kube nokuncintisana okukhulu kuma-prototypes, ukukhiqizwa kwezinga eliphansi kanye nezingxenye zokungena esikhundleni.

Izinguquko engxenyeni ephenduliwe ngokuvamile zisho ukuhlela i-G-code, hhayi ukwenza isikhunta esisha. Onjiniyela bangakwazi ukuphinda basebenzise izimo ngokushesha futhi ba-ode amaqoqo okukhiqiza kuphela lapho idizayini isiqediwe.

Isevisi efanayo yokuphendula nge-CNC esebenza iphrotothaipi eyodwa ingasebenza izingcezu ezingu-10, 100, 10,000 noma 100,000 ngekhwalithi efanayo — yingakho ama-OEM ethatha ukuphendulwa nge-CNC njengesixazululo somthombo owodwa kusukela ku-R&D kuze kufike ekukhiqizeni ngobuningi.
