Kei te teka āu poraka ine maitai ki a koe.
Kāore i te āta whakaarohia. Engari i muri i ngā marama e ono o te whakamahinga o te papa o te toa—te tauhiuhi o te wai whakamatao, te hurihanga o te pāmahana i waenga i ngā huringa o te ata me te ahiahi, te hekenga o te pereti rino maka i ētahi wā—tērā pea ko taua poraka "10mm" he 10.0003mm. 9.9997mm rānei. Ā, ki te whakamahi koe i ngā ātete 5-micron, ka whakakotahi aua hapa iti hei wāhanga para.
Koinei te raruraru puku e kore e kōrerotia e te tangata i roto i te miihini tika.
Koinei te mea e tupu ana me ngā ine maitai i roto i ngā taiao whakaputa.
Ka waikura te maitai. Ahakoa ngā momo "waikura kore waikura" ka taea te pakaru me te paru ina pāngia e ngā wai whakamatao, ngā hinu tapahi, te haumākū nui rānei i roto i te wā. Kia puta he waikura iti rawa ki ngā mata mahi, ka rerekē tō whanonga pēhi. Kāore ngā poraka e tū tika ana. Ka neke te teitei.
Ka pakaru te maitai. I ia wā ka whakakorikori koe i tētahi puranga poraka ine, he iti noa ngā rauemi e tangohia ana mai i ngā mata. I muri i ngā huringa maha—i runga i tō whakamahinga, i ētahi rau pea o ngā puranga hanga—ka heke te tika o ngā inenga ki tua atu i te manawanui. Tērā pea kāore tō tiwhikete whakatikatika mai i ngā tau e rua ki muri e whakaata i tāu e ine ana i tēnei rā.
Ka kawe te maitai i te aukumetanga. I roto i ngā taiwhanga ine me ngā pokapū miihini CNC, ka pā te pokanoa aukume mai i ngā taputapu tata ki te whanonga o te ine maitai. Ehara i te mea i ngā wā katoa, ehara i te mea nui rawa—engari i roto i ngā tono tino tika, ka nui rawa te "kāore i te nui".
Ka whakawhanui te rino i te pāmahana. Ae, e mōhiotia ana te tauwehenga whakawhanui wera o te rino, ā, e whakamāramahia ana tēnei e ngā taiwhanga pai. Engari ko ngā piki me ngā heke o te pāmahana puta noa i te rā whakaputa ka puta he iti engari he tino rerekētanga o te ine.
Ka karohia ēnei raruraru katoa e ngā taputapu ine uku.
Ehara i te makutu—engari ko te matū me te ahupūngao anake e mahi ana i tā rātou mahi.
Hei tauira, ko te uku zirconia. Ko te pakeke o te 1200-1450 HV1, ki te whakaritea ki te 700-800 HV pea mō te maitai whakapakeke. Ko te tikanga o tēnei, ko ngā poraka ine i hangaia mai i te zirconia ka pāngia e te kotahi tekau o te tere pakaru. I roto i tētahi pūtau huri tika kua tuhia, ko te huri ki ngā poraka ine uku ka roa ake ngā wā whakatikatika mai i ia marama torutoru ki ia tau. Ko te waikura i pā ki ā rātou puranga maitai i roto i te kohu whakamatao i ngaro noa atu.
He rerekē te āhuatanga kore-aukume mō ētahi tono. He nui ake te ātete o te mata o te Zirconia i te 10^14 Ω·cm—he ārai hiko, kāore rawa he aukume. Mā tēnā ka kore e puta ngā taonga kukume aukume ka taea te whakapē i ngā hua tirotiro. Mena kei te ine koe i ngā wāhanga peera, kei te mahi tata rānei ki ngā taputapu maka aukume, he mea nui tēnei.
Ā, he tino whaihua te whanonga wera. Ko te tauwehenga whānui wera o te Zirconia kei te 1×10^-5/°C. He rite tonu tēnei ki te maitai, ko te tikanga kāore e hiahiatia he whakahounga katoa mō ō tataunga utu wera. Engari kāore te uku e kawe wera i te ara kotahi, nō reira he iti noa ngā pikinga pāmahana i roto i te taputapu. He pumau te pānui ka whiwhi koe i muri i te 30 hēkona o te pa, kāore e nekeneke haere i te mea ka āta taurite te taputapu.
Nā, ko te pātai tūturu: zirconia, alumina rānei?
Ka toa te zirconia i runga i te pakari. He mea e kiia nei ko te "whakapakaritanga whakawhiti" - ina pēhia, ka paku whakarerekē te āhua e ātete ana ki te horapa o te ngatata. Mā tēnei ka ngāwari ake te murunga mēnā ka taka he poraka ine. He pakeke ake te alumina engari he pakarukaru ake; ka taea e ngā pānga te pakaru.
Ko te kaha piko o te Zirconia, tata ki te 1100 MPa, he toru pea te kaha o te alumina. Mēnā he uaua te whakamahi i ō taputapu, he ngāwari ake te whakamahi i te zirconia.
Engari he wāhi anō tō te alumina. He iti ake te utu, he mārō tonu (HV 1200+), ā, mō ngā tono e hiahia ana koe ki te whakawhanuitanga wera iti rawa - pērā i te inenga whatu - he pai te CTE iti o te alumina. Ko ētahi toa whatu tino tika e pai ake ana ki te alumina nā te mea he iti ake te nekenekehanga i te pāmahana.
Mō te nuinga o ngā mahi miihini tika, ko te zirconia te mea tino pai. He tino painga te roa o te mahi, ā, ko te utu nui ka whakahokia mai mā te roa o te ora mahi me te iti o ngā whakatikatika.
He aha te āhua o tēnei i roto i te mahi?
I roto i te hanga peera, ka tirohia e ngā pine ine uku ngā diameter o roto, o waho hoki o te reihi i te rā katoa. Ko ngā pine maitai i roto i taua taiao? Ko te pānga o te hauhautanga, te poke o ngā matūriki whakarewa, te whakahaere tonu. Kāore ngā pine uku e waikura, kāore e kukume i ngā paru whakarewa, ā, nā te pakeketanga teitei ka roa ake te noho o ngā mata ine i roto i te manawanui. I kōrero tētahi kaihanga peera kua heke te tere whakakapinga o ā rātou pine tirotiro mā te 80% pea i muri i te huri ki te uku.
I ngā toa hanga pokepoke me ngā toa taputapu, ka inehia e ngā poraka-V uku me ngā taha tika te hohonutanga o te kōhao, te matotoru o te mata, me te tūnga o ngā taputapu. He mea nui te kore tiaki i konei—kāore he paninga hinu, kāore he tirotiro waikura, kāore he manukanuka mō te mea i mahue te pereti taha i te pō kotahi. Tukua, horoia, whakamahia.
I roto i te hanga wāhanga whatu, ka pā ngā taputapu ine uku ki ngā karāhe me ngā porotiti e kore e taea te rakuraku. Ko te taratara o te mata o ngā poraka ine uku kounga teitei—Ra ≤ 0.2 maikiromita—e kore e kino ki te karāhe whatu kua orohia. Ā, nā te mea he koretake te uku i roto i ngā matū, kāore he mōrearea o te poke o te katote konganuku e pā ana ki ngā paninga karāhe, ki te kaha whakawhiti rānei.
I roto i ngā hikohiko haurua-ira me ngā hikohiko, ka whakakorea e ngā āhuatanga kore-arataki, kore-aukume te pokanoa ki ngā pūnaha ine e hangai ana ki te kaha me te whakaawe. Ka taea e ngā taputapu maitai e tata ana ki ngā wāhanga tairongo te whakaputa i ngā momo raruraru ngawari katoa e uaua ana ki te whai.
E torutoru ngā mea whai hua hei mōhio.
He rite te mahi a te kōwhiringa tohu ki ngā poraka ine maitai: Tohu 0, 1, 2, me te 3, e ai ki ngā paerewa ISO 3650. Ko te nuinga o ngā mahi miihini tika me Tohu 0, Tohu 1 rānei. Mena kei te mahi koe i te mahi kāore e hiahiatia ana taua taumata tika, kaua e utu mōna.
He māmā ake te rokiroki i te maitai. Kāore he hinu, kāore he takai ārai waikura, kāore he kāpata whakahaere haumākū e hiahiatia ana. Me horoi noa te rokiroki i roto i te pouaka e haere tahi mai ana. Kāore i te pakarukaru, engari mā te tiaki i a rātou ka poto noa te ora o tētahi taputapu.
Me whakatikatika tonu. Kāore te uku e whakakore katoa i te nekenekehanga—he puhoi ake i te maitai. Ko te whakatikatika ā-tau te paerewa mō ngā taputapu e whakamahia ana mō te whakaputa; ko ētahi toa e akiaki ana ki te 18-24 marama mēnā he iti noa te whakamahinga.
He pono te utu nui engari he whaitake. Me tumanako ka nui ake te utu i mua i te 30-50% i ngā mea rite ki te maitai. Engari ki te whakaarohia ngā wā whakatikatika roa, te whakaiti i te auau whakakapinga, me te kore he pakaru e pā ana ki te waikura, he maha ngā wā ka rite ake, ka pai ake rānei te utu katoa mō te mana pupuri i roto i ngā tau e rima.
Anei tētahi whakataurite tere hei whakamārama i tēnei.
Tō huinga poraka ine maitai, te whakamahinga whakaputa, ngā āhuatanga o te papa o te toa:
- Te whakatikatika i ia 3-6 marama nā te mea kua pakaru, kua waikura hoki
- Te whakakapinga o ngā poraka e whakamahia nuitia ana i ia 2-3 tau
- Ngā hapa ine i ētahi wā nā te waikura, te pirau rānei o te mata
- Te horoi me te hinu i ia rā hei ārai i te waikura
Te whakamahinga ōrite, ngā poraka ine uku:
- Te whakatikatika i ia 12-18 marama
- Whakakapinga anake mēnā kua pakaru te tinana
- Whēkenga ine ōrite, matapaetia
- Horoia, rongoatia, oti
He tino rerekētanga taua rerekētanga o te rere o ngā mahi. Ā, i roto i tētahi toa pukumahi e kore nei e mahi tika ngā kaimahi hangarau QC, he mea tino whai hua te tango i tētahi taurangi tiaki mai i te whārite.
Ko te whai huatanga o ngā taputapu ine uku mō tāu mahi, kei runga i tō āhuatanga motuhake.
Mena kei te whakamahi koe i ngā taunga iti, kei te mahi i roto i ngā taiao uaua, kei te whakapau kaha rānei koe ki te tiaki i te poraka ine, he pai pea te tūhura i te pana. Tīmata ki te huinga kotahi—he kete poraka ine taketake i roto i tō awhe tino noa—ka tirohia me pēhea tana mahi ki tō rerenga mahi o nāianei.
Ko te nuinga o ngā toa e whakamātau ana i te uku kāore e hoki anō ki te maitai.
