1. Kungani Umshini Wokucija Udingeka Ekwenziweni Kwengxenye Yenjini Yezindiza
Izinjini ze-aerospace (ama-jet turbines, compressor, hydraulic systems, ama-injection fuel, njll.) zidingaukubekezelelana okuqinile kakhulu, ama-surface finishes alawulwayo, futhicindezela{{0}izindawo ezikhululekile.
Ukugaya okuvamile (ukugaya, ukucindezelwa, ukulungisa kabusha) akukwazi ukufeza lokhu ngasikhathi sinye.
Ngakho-ke, ukunakekelwa kuyadingeka ukuze:
Finyelela{0}}ukunemba kobukhulu obunembile- ukubekezelelana ngokuvamile ngaphakathi±1–2 µm.
Khiqiza ama-surface finishes aphezulu- ngokuvamileI-Ra 0.05–0.2 µm.
Lungisa amaphutha ejiyomethrinjengokuphuma{{0}ku{1}}ekuzungelezeni, kwe-taper, kanye nokuphaphazela.
Thuthukisa ukusebenza kwe-tribological- ukugcinwa kukawoyela, ukungqubuzana okuncishisiwe, nokungagugi.
Thuthukisa ubuqotho bendawongokususa insimbi egcotshiwe kanye-nezinhlamvu ezincane ezigabeni zangaphambilini zomshini.
Gcina ukuhleleka nokugxilaphakathi kwezithukuthuku ezibucayi kanye nezingxenye zokukhwelana.

5. Inqubo Yokujula Yenziwa Kanjani (Isinyathelo-nge-Isinyathelo)
Isinyathelo 1 - Sokulungiselela
Ingxenye ye-aerospace (isb., i-valve body noma i-brearing house) iqiniswe ngokuvikelekile ngokuqondana okunembayo.
Inhlanzekoibalulekile - ngisho nemfucumfucu emincane ingashintsha ukuqedwa kwezinga elincane{1}}.
Okulungileithuluzi elilimazayo(itshe, umkhono, noma{0}}i-pass mandrel eyodwa) ikhethwa ngokusekelwe ezintweni (isb, i-Inconel, i-titanium, insimbi engagqwali, ama-nickel alloys).
Isinyathelo 2 - Sokusetha Ithuluzi
I-honing mandrel ifakweamatshe abrasive(imvamisaidayimanenomaI-CBN) kufakwe nge-radially.
Ukunwetshwa kwethuluzii-servo noma ilawulwa ngamanzingomfutho ofanayo.
Amapharamitha afanaubude be-stroke, isivinini sokuphotha, ingcindezi, nezinga lokuphakelayoahlelwa nge-CNC.
Isinyathelo 3 - Ukusebenza Kokuhlonipha
(a) Ukuzungezisa Kanye Kanye Nokubuyiselana
Ikhanda elicijayoiyazungeza (100–400 rpm)ngenkathii-axially (10–30 m/min).
Lokhu kunyakaza kususa izinto ezincane (imvamisa engu-0.005–0.05 mm) futhi kukhiqiza indawo ekahle,{2}}echanyuselwe.
(b) Okokupholisa kanye Nokugcobisa
Amafutha-ekhwalithi ephezulu e-honing noma i-emulsion ihlinzekwa ngokuqhubekayo:
Hlanza imfucumfucu e-abrasive
Vimbela ukukhiqiza ukushisa
Gcina ukuzinza kwe-dimensional
(c) Ukulinganisa{0}}Isikhathi Sangempela
{0}Kucutshungulwa izikali zomoyanomaIzinzwa ze-LVDTqapha usayizi bore kanye roundness.
Umshini uyama ngokuzenzakalelayo lapho ubukhulu obuqondiwe bufinyelelwa (ukuvala ngokuzenzakalelayo-kuvaliwe).
Isinyathelo 4 - Ukuqeda noma i-Plateau Honing
I-grit encane nomashayela i-honing passkulandela ukwakha aindawo eyithafa:
Iziqongo zilinganiselwe
Izigodi zisala ukuze kugcinwe uwoyela
Uzuza u-Ra 0.05–0.2 µm, Rz 0.3–0.8 µm
Lesi sinyathelo sibaluleke kakhuluama-hydraulic bores kanye nezindlu zokuzala, lapho ukugcoba nokubekwa uphawu kubalulekile.
Isinyathelo 5 - Sokuhlola Nokuqinisekisa
Okuthunyelwe{0}}ukucijwa, izingxenye ziyaqhubeka:
Isilinganiso segeji yomoya(ububanzi, ubuyindilinga)
Surface profilometry
Ukuqinisekiswa kokulungiswa kwe-Bore
Ukuhlolwa kwenhlanzeko(ISO 16232 noma okulinganayo)
Zonke izilinganiso zirekhodwa ngokwedijithaliukulandeleka kanye nesitifiketi sekhwalithi.
6. Amapharamitha wenqubo ejwayelekile
