1. Lwaki Ekyuma Ekirongoosa Kyetaagibwa mu Kukola Ebitundu bya Yingini Y’omu Bbanja
Yingini z’omu bwengula (jet turbines, compressors, hydraulic systems, fuel injectors, n’ebirala) zeetaagaokugumiikiriza okunywevu ennyo, okufugibwa okumaliriza kungulu, nestress-ebifo ebitaliimu situleesi.
Okukozesa ebyuma okwa bulijjo (okusena, okuboola, okusiba) bulijjo tekuyinza kutuukiriza bino mu kiseera kye kimu.
N’olwekyo, okulongoosa kyetaagisa okusobola:
Tuuka ku butuufu bw'ebipimo obutuufu (ultra-precise dimensional accuracy- okugumiikiriza emirundi mingi munda±1–2 µm.
Fulumya ebimalirizo eby’okungulu eby’ekika ekya waggulu- mu ngeri entuufuRa 0.05–0.2 μm.
Okutereeza ensobi za geometrynga out-of-obuzito, taper, n'amayengo.
Okulongoosa enkola ya tribological- okusigala kw’amafuta, okukendeeza ku kusikagana, n’okuziyiza okwambala.
Okwongera ku bulungibwansi bw’okungulunga tuggyawo ebyuma ebisiigiddwa ne micro-burrs okuva mu mitendera egy’okukola ebyuma egyayita.
Kuuma alignment ne concentricitywakati w’ebifo ebikulu n’ebitundu ebigatta.

5. Engeri Enkola y’Okulongoosa Gy’ekolebwamu (Step-by-Step) .
Omutendera 1 - Okuteekateeka
Ekitundu ky’omu bwengula (okugeza, omubiri gwa vvaalu oba ennyumba ya bbeeri) kinywezeddwa bulungi nga kikwatagana bulungi.
Obuyonjokikulu nnyo - n'ebisasiro ebitonotono bisobola okukyusa micron-level finishes.
Ekituufuekintu ekikozesebwa mu kusiiga(ejjinja, sleeve, oba single-pass mandrel) erondebwa okusinziira ku bintu (okugeza, Inconel, titanium, ekyuma ekitali kizimbulukuse, nickel alloys).
Omutendera 2 - Okuteekawo Ebikozesebwa
Mandrel ey’okulongoosa (honing mandrel) essiddwaakoamayinja agasiiga(mu ngeri entuufudayimandaobaCBN) esimbiddwa mu ngeri ya radial.
Okugaziya ebikozesebwa kweservo oba efugirwa mu mazziku puleesa eya kimu.
Parameters ngaobuwanvu bwa stroke, sipiidi ya spindle, puleesa, n’omutindo gw’emmereziteekebwa mu pulogulaamu nga ziyita mu CNC.
Omutendera 3 - Okulongoosa Enkola
(a) Okuzimbulukuka n’okuddiŋŋana mu kiseera kye kimu
Omutwe ogw’okulongoosaekyuka (100–400 rpm) .nayeokukyukakyuka mu ngeri ey’ekyekulungirivu (10–30 m/min) ..
Entambula eno eggyawo ebintu ebitonotono (ebitera okuba mm 0.005–0.05) era n’ekola ekifo ekirungi, ekisala-ekikutuddwa.
(b) Ekinyogoza n’okusiiga
Amafuta oba emulsion ow’omutindo ogwa waggulu-okuweebwa buli kiseera eri:
Fulumya ebisasiro ebisiiga
Okuziyiza okukola ebbugumu
Kuuma obutebenkevu bw’ebipimo
(c) Okupima Ebiseera Ebituufu-
Mu-ebipima empewo mu nkolaobaSensulo za LVDTlondoola obunene bwa bore n’obuzito.
Ekyuma kiyimirira mu ngeri ey'otoma nga ekipimo ekigendererwa kituuse (auto shut-off).
Omutendera 4 - Okumaliriza oba Okulongoosa Plateau
A grit esingako obulungi obabrush honing okuyitakigoberera okutondawo aku ngulu okuli plateaued:
Entikko zibeera za level
Ebiwonvu bisigaddewo okukuuma amafuta
Atuuka ku Ra 0.05–0.2 μm, Rz 0.3–0.8 μm
Omutendera guno mukulu nnyo naddala eri...ebituli by’amazzi n’ebiyumba bya bbeeri, nga okusiiga n’okusiba bikulu nnyo.
Omutendera 5 - Okukebera n'okukakasa
Post-honing, ebitundu biyita mu:
Okupima ekipima empewo(diameter, okwetooloola) .
Okupima ebifaananyi ku ngulu
Okukakasa okukwatagana kwa bore
Okukebera obuyonjo(ISO 16232 oba eyenkanankana nayo)
Ebipimo byonna bitera okuwandiikibwa mu ngeri ya digito ku...okulondoola n’okukakasa omutindo.
6. Ebipimo by’Enkola ebya bulijjo
| Parameter | Range eya bulijjo | Omugaso |
|---|---|---|
| Okuggyawo Sitooki | 0.005–0.05 mm | Okutereeza ebipimo okusembayo |
| Obukaluba bw’okungulu (Ra) . | 0.05–0.2 µm | Okumaliriza kwa waggulu okusiiga |
| Okwetoloola | Ekitono oba ekyenkana 1–2 μm | Bbalansi ya sipiidi ya waggulu-n'okusiba |
| Omusalaba-Enkoona y'okusala | 20 diguli –40 diguli | Okukuuma amafuta okufugibwa |
| Okufuga Ebbugumu | ±0.5 diguli | Okukwatagana kw’ebipimo |
7. Mu bufunze
| Ekifo ekilondemu kukintu | Okunnyonnyola |
|---|---|
| Obwetaavu bwa Honing | Tuuka ku butuufu obuyitiridde, okutuukirizibwa kungulu, n’okwesigamizibwa mu bifo ebikulu ebya yingini z’omu bwengula. |
| Ekika ky’Ekyuma | Ebyuma bya CNC eby’okulongoosa mu ngeri entuufu (vertical precision precision honing systems) (ebiseera ebisinga nga birina enkola za dayimanda eziyita mu ngeri ey’ekika kya multi-spindle oba single-pass). |
| Emirimu | Okutereeza ebipimo, okumaliriza kungulu, okutuukirizibwa kwa geometry, okulongoosa obulungi bw’okungulu. |
| Enkola y’Enkola | Controlled abrasive machining nga okukyusakyusa n’okuddiŋŋana mu kiseera kye kimu, wansi w’ekinyogoza, nga mu-process gauging. |
| Ebivudemu | Ultra-precise, stress-free, wear-resistant surfaces ezikakasa obulamu obuwanvu obw'okuweereza, obulungi, n'obukuumi bwa yingini z'omu bwengula. |
