Bw’oba okola ku pulojekiti, okumanya oba okukozesa obuwuzi bwa UNF oba UNC busobola okukola oba okumenya omulimu gwo. Okupima n’okuzuula obuwuzi buno kikakasa bulungi nti ebisiba byo bikwatagana bulungi, ka kibeere ng’ozimba ekitundu ky’ebintu, okuddaabiriza mmotoka, oba n’okukuŋŋaanya ebitundu by’omu bbanga. Ebipimo ebirungi bivaako okuyungibwa okw’amaanyi, okutebenkedde, era okutaliimu bulabe mu kyonna ky’okola oba okuddaabiriza.
Okukozesa mu nkola n'okutegeera amakolero .
UNF threads mu precision adjustments ne fixations .
UNF (Unified National Fine) threads ziringa abakugu mu by’obuwuzi mu nsi ya thread. Wano ddala we zisinga okulabika obulungi:
l Aerospace and Aviation : Mu nnyonyi n’ennyonyi, buli kitundu ekitono kiteekwa okuba nga kituukiridde. Obuwuzi bwa UNF bukozesebwa mu bitundu bya yingini n’ensengeka z’omubiri olw’obutuufu bwabwo obw’amaanyi.
l Automotive Manufacturing : Mu mmotoka naddala mu bitundu ebisinga okuba ebigonvu nga ebitundu by’amasannyalaze , UNF threads ziwa fitting entuufu eyeetaagisa.
l Ebyuma ebikozesebwa mu by’amasannyalaze : Ku gadgets n’ebyuma, nga buli milimita ebala, UNF threads zeetaagisa nnyo okusobola okutuufu n’okuyungibwa okunywevu ..
UNC threads mu bungi okukola ebisiba .
Bwe kituuka ku kukola ebisiba bingi mu bwangu era mu ngeri ennungi, UNC (Unified National Coarse) threads ze zigenda:
l Okuzimba : Mu bizimbe n’ebintu ebikozesebwa, obuwuzi bwa UNC bukozesebwa mu buuma ne sikulaapu olw’amaanyi gaabyo n’obwangu bw’okukozesa.
l Ebyuma eby’enjawulo : Ku byuma ebyetaaga ebisiba ebinywevu era ebyesigika, threads za UNC ziwa bbalansi entuufu ey’amaanyi n’obwangu bw’okukwata.
Enkozesa y'amakolero ekwata ku UNF ne UNC threads .
Buli kika kya thread kirina amaanyi gaakyo agasukkulumye ku makolero ag’enjawulo:
l UNF threads : Mu precision instruments ne aerospace , nga buli kantu kakulu, UNF threads zeetaagisa nnyo okusobola amaanyi gazo aga waggulu n’obutuufu ..
L UNC Threads : Mu makolero nga okuzimba n’ebyuma ebizito, ebisiba nga byetaaga okuba ebikaluba era ebyesigika, UNC threads ze zisinga okwagalibwa.
Okusoomoozebwa mu kukola ebyuma n'okukuŋŋaanya .
Okukola ne threads si kyangu bulijjo. Wano waliwo okusoomoozebwa:
l Precision mu Machining : Okukola UNF threads kyetaagisa high precision mu CNC machining . Ensobi entonotono esobola okuleeta enjawulo ennene.
l Enkwata n’okukuŋŋaanya : UNC threads, being coarser, enyangu okukwata naye zirina okukolebwa n’obwegendereza okukakasa nti zikwata bulungi mu nkola ezitali nnungi.
L Okulonda ebintu : Okulonda ebintu ku wuzi zombi eza UNF ne UNC kikulu nnyo. Kikosa amaanyi , g’obuwuzi , n’okuziyiza situleesi.
Ka kibeere okukozesa emitwe gya UNF mu ngeri ey’obutuufu mu bbanga n’eby’amasannyalaze bitundu by’omu oba obugumu bw’obuwuzi bwa UNC mu kuzimba n’ebyuma, byombi bikola emirimu emikulu mu bintu byabwe. Okutegeera enkozesa yaabwe entongole n’okusoomoozebwa kiyamba mu kukola okulonda kw’obuwuzi obutuufu ku buli nkola ey’enjawulo, okukakasa obulungi n’obukuumi bw’ekintu ekisembayo.
Okulonda Ekika ky'Obuwuzi Ekituufu .
Ensonga z’olina okulowoozaako ng’olonda wakati wa UNC ne UNF .
Okulonda ekika ky’obuwuzi obutuufu – UNC oba UNF – kikulu nnyo. Bino by'olina okulowoozaako:
1. Application Needs : Okola ku kintu ekyetaaga precision eya waggulu, nga ekitundu ky'ennyonyi ? Genda ku UNF. Ku kuzimba okwa bulijjo, UNC ye bbeeti yo esinga obulungi.
2. ebyetaago by’amaanyi : UNF threads zikuwa amaanyi mangi olw’eddoboozi lyagyo ennungi, ekigifuula ennungi mu kukozesa situleesi ey’amaanyi.
3. Assembly Environment : Singa obutonde butera okubeera obucaafu oba okwonooneka, UNC's coarser threads zisinga kusonyiwa.
4. Obusobozi bw'okukola : Olina ebyuma ebikola UNF threading entuufu? Bwe kitaba bwe kityo, UNC eyinza okuba ey’omugaso ennyo.
Emitendera n'enkuŋŋaana z'amakolero .
Buli makolero galina bye gasinga okwagala:
l Aerospace : UNF etera okukozesebwa mu butuufu bwayo obw’amaanyi n’amaanyi gaayo ..
