I kēia manawa, ʻo nā ʻano ana o ka ʻoki ʻia ʻana o ka paipu i loko o ka ʻoihana e pili ana i ke ana pololei, ke ana kūpaʻa, a me ke ana kahua kūikawā.

1.Square ana
ʻElua mau wāwae ka lula huinaha i hoʻohana ʻia no ke ana ʻana i ka ʻoki ʻia o ka hopena paipu.Ma kahi o 300mm ka lōʻihi o kekahi wāwae a hoʻohana ʻia e hoʻopili i ka ʻili o ka paia o waho o ka hopena paipu; ʻoi aku ka lōʻihi o ka wāwae ʻē aʻe ma mua o ke anawaena paipu a hoʻohana ʻia ma ke ʻano he ana wāwae i ka waha paipu, .I ka ana ana i ka paipu hope incline, na wawae e kokoke i ka waho paia o ka paipu hopena a me ka nozzle, a me ka paipu hopena incline waiwai ma keia aoao e ana me ka feeler gauge.
Hoʻohana ke ʻano ana i nā mea hana maʻalahi a me ke ana maʻalahi.Eia naʻe, pili ka hewa o ke ana ʻana e ka palahalaha o ka paia o waho o ka hopena o ka paipu i ka wā e ana.Eia kekahi, inā nui ke anawaena o ka paipu kila e ho'āʻoʻia, pono e hoʻohanaʻia kahi'āpana nui, he kaumaha a paʻakikī ke lawe.

2. Ana kū pololei
Me ka hoʻohana ʻana i ʻelua mau huila wili, kau ʻia ka paipu kila ma luna o laila, ʻaʻole pono e hoʻopalike ʻia ka paipu kila.E kau i kahi pale me ka hāmare uwea ma ka ʻili luna o ka paia o waho o ka hopena paipu e hoʻāʻo ʻia.Hoʻopaʻa ʻia ka bracket ma ka ʻili luna o ka paia o waho o ka hopena paipu.Kau ka hāmare uwea ma ka waha o ka paipu a he mamao loa ia mai ka welau o ka paipu, a e mau ana kona kulana i ke ana ana ma na aoao elua.
ʻO ka mua, e ana i ka mamao ma waena o ka ʻili hope a me ka piko haʻahaʻa o ka paipu a me ka laina kūpaʻa, a laila e hoʻohuli i ka paipu kila 180 °, a ana i ka mamao ma waena o ka ʻili hope a me ka piko o lalo o ka paipu a me ka laina kū i loko. ke ala like.Ma hope o ka lawe ʻana i ka huina o nā ʻokoʻa o nā kiko pili, e lawe i ka waiwai awelika, a ʻo ka waiwai paʻa ka waiwai chamfer.
Hoʻopau kēia ʻano i ka mana o ka laina kūpaʻa ʻaʻole kū pololei i ke axis o ka paipu kila.Ke hili ʻia ka paipu kila, hiki ke ana pono ʻia ka waiwai tangential o ka hopena o ka paipu kila.Eia nō naʻe, pono nā mea paahana e like me ke kaʻa kaʻa a me ka hāmare uea i ke kaʻina ana, he pilikia.

3. Ana anuu kūikawā
ʻO ke kumu o kēia ʻano ana ʻano like me ke ʻano kuʻuna.ʻO ka paepae ana i haku ʻia me kahi paepae, kahi ʻōwili ʻōwili, a me kahi ʻāpana ana.ʻAʻohe pono e hoʻoponopono i ka perpendicularity ma waena o ke axis paipu kila a me ke ana ʻana i ka wā ana.E kau i ke ana ana i ka waha o ka paipu a he 10-20mm ka mamao mai ka waha o ka paipu.ʻO ka waiwai chamfer ka huina o nā ʻokoʻa o nā kiko pili, a laila ka waiwai maʻamau, a laila ka waiwai piha.
He mea maʻalahi kēia ala e ana i ka mamao ma waena o nā piko o luna a me lalo a me ka huinahā, a ʻoi aku ka pololei ma mua o ke ana kū pololei.Eia naʻe, ʻoi aku ka pipiʻi o nā mea hana kōkua a ʻoi aku ka nui o ke kumukūʻai ana.
Ma waena o nā ʻano ʻekolu, ʻoi aku ka maikaʻi o ke ʻano ana o ka paepae i hoʻolaʻa ʻia a ua ʻōlelo ʻia no ka hana ʻana i ka paipu kila ma ka pūnaewele; ʻO ke ʻano o ke ana ʻana i ka huinahā ka haʻahaʻa haʻahaʻa, a ua ʻōlelo ʻia e ana Hoʻohana ʻia no nā paipu kila me nā anawaena liʻiliʻi.
