Hei kaihanga o te Mīhini Mira Niho, kua ahu mai ā mātou taunakitanga i ngā rau o ngā take kaiwhakamahi me ngā whakamātautau whānui i roto i te whare. Ka taea e ēnei tikanga e 5 te whakaoti i te 90% o ngā take maramara i roto i te mira zirconia kua whakatōngia i mua.

Mā tēnei aratohu koe e whakaatu: ngā tikanga matua e rua mō te whakakoi zirconia; me pēhea te whakatinana i tētahi rautaki tapahi paparanga-toru ki te DN-D5Z; me pēhea te whakataurite i te tere o te porowhita me te tere whāngai hei karo i te kukū o te ahotea; he aha te hiranga o te tūnga hau-pū i tō whakaaro; āhea me whakapae te mīhini hei utu mō te whakarerekē i ngā tawhā. Hei te mutunga, ka taea e koe te tautuhi i ngā take o te whakakoi, te whakatau i ō whakaritenga, me te mōhio āhea me whakapā atu ki te tautoko hangarau.

Te Hua o te Tapahi Zirconia: Ngā Tikanga e Rua Me Mārama Koe

He pakarukaru te zirconia kua oti te whakakoi i mua, pērā i te uku kāore anō kia tahuna. E rua ngā take matua o te mira maramara—mā te mārama ki ngā mea e rua ka taea e koe te whakarerekē i ngā tawhā me te tika.

Tikanga tuatahi: Te kukū ahotea ā-rohe

He pānga tēnei. Ki te patu koe i te uku ki te hama poutū ki tōna taha, ka whati—ahakoa te kaha. He rite tonu te mahi a te mira. Ina ruku poutū tō taputapu ki roto i te zirconia, ina hoki whakamuri rānei, he rite ki te pānga moroiti. Ka aro te kaha ki te taha; kāore he wā o te uku ki te urutau; ka nui ake i te rohe ahotea ka whati. Ko tēnei momo pakaru he hapa kotahi, nui, kua tautuhia pai.

Tikanga tuarua: Te kohikohi wera me te haehae

He rite te zirconia kua whakatōkia ki te uku ki te uku i mua i te tahunga. Ka kohia te wera o te mira ki roto i ngā pūwero moroiti, ā, kāore e memeha. Ka piki ake te pāmahana o te rohe ki te 100°C, neke atu rānei, i roto i ngā hēkona. Ka piki ake te pakarukaru, ka whakaiti hoki i te pakari o te pāmahana teitei. Ki te haere tonu ngā kaha tapahi, ka haehae koe, kaua e tapahi—ka taratara, ka pakarukaru te taha, kaua e motuhia kia ma.

Hei whakarāpopototanga: ka whakaatuhia te momo maramara pānga hei hapa nui; ka whakaatuhia te maramara kohikohi wera hei taha taratara, haehae. Ka taunekeneke ngā tikanga e rua—ka whakanuia te wera e te ahotea; ka whakanuia te pakarukaru e te wera. Koia te take e arohia ai e te whakatikatika tawhā ngā mea e rua.

Tohutohu 1: Rautaki Tapahi Papa-Toru—Te Pūtake o te Ārai i te Pakaru

He tokomaha ngā kaiwhakamahi e peke tika ana ki te whakaoti i ngā whitinga, ā, e miharo ana he aha i pakaru ai ngā taha. Kāore te tapahi paparanga-toru e moumou taima—ka tohatohahia te kawenga ahotea ki ngā whitinga maha kia ngawari ai te whitinga whakamutunga.

Te Whakatārewatanga: Te Tango Tere i te Papatipu

Koinei te huarahi "whakapatunga tapu". Ko tāu whāinga anake: tangohia wawe te 70% o ngā rauemi. Kāore he aha te āhua o te mata i tēnei wā.

• Tere o te miro: 30,000–40,000 RPM
• Te tere whāngai: Ka whakatauhia e tō pūmanawa CAM (he tere te nuinga)
• Te tahua penapena: 0.3–0.5mm (whakarerekētia kia rite ki te uaua o ngā wāhanga; ka taea e ngā piriti te waiho i ētahi atu)
• Utauta: Ihu-pōro, ihu-papatahi rānei hei tango i te puranga

Ka kite koe i ngā mata taratara me ngā haehae iti—he mea noa tēnei. Ka puta he ahotea ā-roto ki ngā taha i te wā e taratara ana, engari he mea āta whakaarohia tēnā. Mā ngā kōrero e whai ake nei ka whakamārama i tēnei.

Whakaoti-haurua: Te Whakamarumaru me te Whakaora i te Taumahatanga

Mā te whakaotinga-haurua ka whakangawari i te mata taratara, ka whakamarara hoki i te ru o te taratara. He tokomaha ka peke i tēnei taahiraa—kāore.

• Tere o te porowhita: 45,000–55,000 RPM
• Te tere whāngai: Taurite (kāore i te tino kaha)
• Te tahua taonga: 0.1–0.15mm
• Utauta: Ihu pōro angiangi (1.0–2.0mm te whānui)

Ka piki ake te tere o te miro mai i te 30k ki te 45k, ā, ka angiangi haere te taputapu. Ka whai mārire tēnei mahi tapahi i ngā āhua taratara, me te kore e whakanui ake i te wiri. Ka kite koe ka māeneene haere te mata—he tohu pai tēnei e mahi ana te whakatakoto paparanga.

Whakaoti: Te Pāhi Whakamutunga Ngāwari

Koinei te wāhi e honoa ai ngā mea katoa. Mā tēnei putanga ka whakatau te angitu, te kore rānei.

• Tere o te miro: 50,000–60,000 RPM
• Te tere whāngai: Pūmau, ā, he puhoi ake i te taratara (te mea puhoi rawa o ngā haerenga e toru)
• Te tahua penapena: 0 mm (tika ki te rahinga whakamutunga)
• Utauta: Utauta angiangi (0.6–1.0mm), he pai ake te paninga (TiN, TiAlN rānei)

He aha ai te whakanui ake i te tere o te porowhita? Nā te mea ka maeneene ake te tapahi i te RPM teitei, ā, ka tohatoha ōrite te kaha tapahi. Mēnā ka honoa ki te tere whāngai taurite, ka pā te pēhanga pumau, ōrite, me te whakahaere i te taha—ka tapahia ma te uku, kaua e haehae, e whati rānei.

He aha i ārai ai ngā paparanga e toru i te pakaru

Ki te peke tika koe mai i te taratara ki te whakaotinga, me mimiti e te pānga whakamutunga te ahotea katoa kua kohia mai i te taratara—tērā pea ka rahua, ka pakaru.

Tūturu te take: Kotahi te kaiwhakamahi i huri mai i te toru-pānga ki te rua-pānga (kāore i te whakaoti-haurua). I piki ake te tere o te pakaru mai i te 3% ki te 12%. I te hokinga mai, i heke ki te 2%. Koinei te mana o te paparanga.

Tohutohu 2: Ngā Koki Tomokanga me ngā Koki Puta o te Taputapu—Āraia te Tūnga Poutū me te Hoki Whakamuri

He maha ngā pūnaha CAM e whakamahi ana i te tūnga poutū me te hoki whakamuri—ā, he mahanga tēnei.

Te Raru: Te Tomokanga Poutū (Te Ruku)

Whakaarohia te patu poutū ki tētahi pereti uku—ka whati. Mā te ruku tika ki raro ka pērā anō. Ka pā te taputapu ki te mata o te zirconia me te ru; ka aro te kaha ki tētahi pūwāhi i te taha; ka piki tonu te ahotea; ka pakaru te maramara uku.

Te Otinga: Te Tomokanga Arapae

Tukua te taputapu kia whakatata atu ki te zirconia i runga i te arawhata 15°–30°. Ka āta hanga te kaha, kaua e piko. Ka whai wā te taha ki te urutau. Kia tae ki te hohonutanga katoa, kua tohatohahia te ahotea, ā, kua pumau te pēhanga.

Te Raru: Putanga Poutū (Whakahoki)

Ko te kukume tika i te taputapu ki runga he rite ki te tango ohorere i te tautoko katoa mai i te taha. I raro i te pēhanga te uku; inaianei kua kore e tautokona. Mā te whakahurihanga o te ahotea ka whati.

Te Otinga: Putanga Arapae, Whakahoki Porowhita rānei

Hoki whakamuri i te arawhata kotahi 15°–30°, whakamahia rānei te nekehanga porowhita. Ka heke mārire te pēhanga; ka neke mārire te uku; ka noho pūmau ngā taha.

Tatūnga Pūmanawa CAM

He maha ngā mōkihi CAM he tawhā "Lead-in" me "Lead-out":

• Ko te taunoa he "Plunge" (tika ki roto/ki waho) → huri ki "Ramp" "Helix" rānei
• Whakatakotoria te koki o te arawhata ki te 15°–30°
• Ka ngāwari te whakahaere a DN-D5Z i ngā ara uaua, nō reira kaua e mangere ki te whakamahi i ēnei nekehanga

He tauira kua kitea e mātou: He maha ngā hapa pakaru ka puta noa i ngā wāhi tomo me ngā wāhi putanga taputapu. I tā mātou āwhina i ngā kaiwhakamahi ki te huri ki te ara tomo/putanga me te kore e whakarerekē i tētahi atu mea, ka heke te tere pakaru mai i te 8% ki te 3%. Koinei te auau o tēnei hapa.

Tohutohu 3: Te Whakatūnga RPM me te Auau Whāngai—Te Taurite Koura

Koinei te wāhi e puta ai te nuinga o ngā hapa whakaōrite. Kāore e āwhina tonu te RPM tere; kāore hoki e pai ake te whāngai puhoi.

Pōturi rawa te whāngai = Te taratara o te kohikohi wera

Ko te whāngai puhoi te tikanga ka noho roa te taputapu ki te wāhi kotahi. Ka nui haere te wera i roto i ngā pūwero moroiti. Ka mimiti te wera e te zirconia kua whakatōngia i mua, ā, ka pakarukaru. Ka haehae te uku, kaua e tapahia kia ma.

Tohu: He āhua haehae, he taratara ngā taha—me te mea kua haehaea, ehara i te mea kua tapahia. E whakaatu ana te karu tirotiro i ngā rārangi haehae koretake, ehara i te mea he mata tapahi maeneene.

Whāngai Tere Rawa = Ngā Kohao Pīkoki Ātete

Ka hangaia e te whāngai tere ngā tihi kaha tapahi. Ahakoa te RPM teitei, kāore e taea te whakangawari i te koikoi. Ka kukū te ahotea taha; ka pakaru te uku i ngā wā poto, auau.

Tohu: He kōhao iti noa i te taha—he rite ki te tauira niho taputapu.

Te Huinga Toa: RPM Teitei + Whāngai Waenga

• Tere teitei o te miro (50,000–60,000 RPM): He maeneene ake te tapahi, he ōrite te horapa o te kaha, he iti ake te whakanui i te wera
• Whāngai taurite: Taurite—he nui hei ārai i te wera, kaua e nui rawa, engari ka puta he pī

Hua: ka pā te pēhanga pumau, ōrite, me te whakahaere i ngā taha. Ka tapahia ma te uku.

Tukanga Whakatūnga-ā-ringa

1. Tīmata ki te RPM waenga (45,000)
2. Tīmata ki te whāngai waenga (tō turanga CAM)
3. Hurihia he wahi whakamātautau
4. Mena he taratara, he pakaru hoki ngā taha (he tohu wera) → whakanuia te RPM (whakamātauria te 52,000, 58,000 rānei)
5. Mena he iti ngā kōhao o ngā taha (he tohu pikinga ahotea) → whakaitihia te whāngai (whakaitihia mā te 10–20%)
6. Whakahokia mā te whakamahi i ngā whakarerekētanga iti—kimihia tō rohe (e 3–5 ngā wahi whakamātautau e hiahiatia ana)

Whakataurite: Hē me te Tika

Tohutohu Ngaio: Whakamahia ō Taringa

Wareware atu ki ngā tau mō tētahi wā poto. Whakarongo ki te tangi tapahi:

• Tika: He ngawari te tangi "whoosh", he pumau te mīhini, kāore he wiri e kitea ana
• Whāngai tere rawa: He tangi "zzzt" haruru, ka rongo koe i te rūrū o te mīhini
• Pōturi rawa te whāngai: He tangi "zhhhh" ngoikore, ka puta pea te paoa i te pito tapahi (he tohu wera nui)

E toru hēkona o te whakarongo ki ngā pao e titiro ana ki tētahi tau mō ngā meneti. E whakaatu ana ō taringa ki a koe he aha te mahi a ngā tawhā.

Tohutohu 4: Rautaki Whakamatao Hau-Pū - He mea nui te Tūnga me te Pēhanga

He mīhini tapahi maroke te DN-D5Z. He pūwero te zirconia kua whakatōkia i mua, ā, ka mimiti i te wai whakamatao, ka pā ki te whakahekenga me te taunga o te whakatō. Otinga: whakamatao hau. Engari he maha ngā tāngata e hē ana.

He aha i tere ai te wera o te Zirconia kua oti te whakatō

He iti te mātotoru o te mea kua whakatōkia i mua; he nui ngā pūwero moroiti. Ka mau te wera o te mira i roto i aua pūwero—kāore e taea te puta. Ka taea e te pāmahana o te rohe te piki ake i te 100°C+ i roto i te meneti kotahi. Ko te wera he pakarukaru; ko te pakarukaru he pakarukaru. Koinei te huringa.

E toru ngā hapa o te pupuhi hau

❌ Hapa 1: Te pupuhi i te puranga maramara

E whakaaro ana koe kei te whakakore koe i ngā maramara mā te pupuhi i te puranga. Engari, ka pupuhihia ngā maramara ki roto i te tapahi—ka rakurakuhia, ka tapahia anō ngā taha. Ka kino haere te pakaru.

❌ Hapa 2: Te pupuhi i te mata o te wāhanga, ehara i te wāhi i tapahia

Ka pupuhi koe i te mata kua oti, me te whakaaro ka whakamatao te wāhanga. Engari ko te pūtake wera ko te pūwāhi pa o te taputapu me te zirconia, ehara i te mata. He pēhanga hau moumou; kei te piki tonu te wera.

❌ Hapa 3: He teitei rawa te pēhanga hau

Mā te whakaaro ki te nui ake o te pēhanga ka pai ake te whakamatao. Inaa, ka whakapēhia e te nui rawa o te pēhanga te āpure kaha i te tapahi, ka whakanui ake i te ahotea tapahi, ā, ka kino ake te pakaru.

✅ Tatūnga Pūwero-Hau Tika

• Tūnga: Pū hau e aro ana ki te pūwāhi tapahi (rohe pa taputapu-zirconia)
• Koki: 45°–60° (kāore i te poutū)
• Pānga: Ka haria atu te wera e te hau matao; ka pupuhihia ngā maramara kia matara atu i te rohe tapahi
• Pēhanga: 0.5–1.0 pae (pūnaha paerewa DN-D5Z). Whakanuia mārire kia pupuhi rawatia ngā maramara—kātahi ka mutu

Me pēhea te Whakatūnga i te Tūnga o te Pūnga Hau

1. Mātakitaki ki te rere o ngā maramara i te wā e tapatapahi ana
2. Ki te noho tonu ngā maramara i te taha o te tapahi, ki te peke whakamuri rānei → whakarerekētia te tūnga o te hau kia pā tika ki te pūwāhi tapahi
3. Whakanuia te pēhanga hau kia puta rā anō ngā maramara (mātakitaki ā-kanohi)
4. Hurihia he wahi whakamātautau; whakatairitehia te maramara ki te turanga

Kua kite mātou i ngā kaiwhakamahi e whakatika ana i tō rātou tūranga pupuhi hau ko rātou anake, ā, ka mātakitaki i te hekenga o te maramara mai i te 10% ki te 5%—me te kore e pā ki tētahi atu tawhā.

Kua Tātarihia i mua i te Tātarihia me te Tātarihia: Kāore e taea te whakawhiti

• Kua whakatōkia i mua: He pūwero, ka mimiti i te wera, me whakamahi i te whakamatao hau-pūhaumāota
• Kua whakatōkia katoatia: Kiato, ka tere ake te tuku wera, kāore i te tino hira te pupuhi o te hau

He mea nui: Kāore e taea te whakawhiti i ngā tawhā mō te zirconia kua oti te whakatō me te zirconia kua oti te whakatō. Ina whakawhiti rauemi koe, whakamātauria anō.

Tohutohu 5: Rārangi Arowhai Tirotiro Mīhini—Ina Ehara i te Raru ngā Tawhā

Kua whakatikatikahia ngā tawhā mō ngā rā engari kei te pakaru tonu? Tērā pea ko te mīhini tonu te raru, ehara i ō tautuhinga.

Tirotiro 1: Āhua o te Utauta

Te ahunga whakamua o te kakahu o ngā taputapu:

• Utauta hou: He koi ngā taha, he kaha te tapahi, he ngāwari ki te pakaru (me pakaru: 5–10 ngā wahi)
• He iti te pakaru (tino pai): Kei te kitea te pakaru iti, he tino pai te kaha tapahi me te āhua o te mata.
• Kua tawhito: He taha ngoikore, he kaha tapahi matapōkere, he pakaru e kore e taea te karo

Mahi: Tirohia ngā taputapu ia 20–30 ngā wahi mā te whakamahi i te whakanui 10×. Tirohia mēnā he kanapa te taha. Ki te mangu te taha, kua tae ki te wā hei whakakapi.

Tohutohu paninga: Mō te zirconia kua whakatōkia i mua, ka nui ake te mahi a ngā taputapu paninga (TiN, TiAlN) i te kore paninga mā te 20–30%. Ka whai hua te haumitanga ki te whakaiti i te pakaru.

Tirotiro 2: Te Rerenga o te Porowhita

Koinei te tino take e warewarehia ana mō ngā maramara kāore i te whakahaerehia.

Me pēhea te ine: Tāpirihia he tohu waea ki te pito o mua o te miro. Hurihia ki te ringa. Mātakitaki i te nekehanga o te ngira.

Paerewa (DN-D5Z): ±0.01 mm te oma mōrahi

Mena he nui ake i te ±0.02 mm te oma: Me whakatika te poro. Ka wiri te ara o te taputapu; ahakoa ngā tawhā tino tika ka puta he maramara kāore i te whakahaeretia.

Auau tirotiro: Te whakamahinga nui (8+ hāora/rā) → ia wiki. Te whakamahinga noa → ia marama.

Tirohanga 3: Te Pūmautanga o te Maukati Wāhanga

He pakarukaru te zirconia kua whakatōkia i mua. Ka pakaru te zirconia mēnā ka wiri.

Ngā haki:

• Kei te wiri te poraka i te taha ki te taha i roto i te rawhi-C? (Me totoka pērā i te toka)
• Kei te taurite te kaha o te kume? (Kāore i te tino piri—ka pakaru te poraka; kāore i te tino wetekina—ka wiri)
• He wāhanga matotoru rānei kei te pupurihia e te rawhi, he wāhanga angiangi ngoikore rānei? (He wāhanga totoka anake te rawhi)

Tohu o te koretake o te piri: Ka pakaru te poraka i te wāhi kotahi i ia poraka (te wāhi e piko ai te poraka).

Tirohanga 4: Te Mana o te Porowhita me te Tere Wā-Tūturu

Mana mōrahi DN-D5Z: 800W. Mana tonu: 500W.

Raru noa: Ka whakatakotoria e koe te 60,000 RPM, engari ka heke te mīhini ki te 45,000 RPM i raro i te kawenga. He aha ai?

• Kāore e ōrite ngā tawhā me te kaha o te mīhini (he tere rawa te whāngai mō te kaha o te porowhita)
• He ngoikore te taputapu (me nui ake te kaha hei tapahi)

Tirohia: Tirohia te whakaaturanga, te pūmanawa rānei o te DN-D5Z. Kei te ōrite te tere o te porowhita tūturu ki tāu whāinga? Mena ka heke pinepine, whakatikatikahia ngā tawhā, whakakapia rānei te taputapu.

He aha te 70% o te Tapatapa he Tawhā; 30% he Mīhini

O ngā hapa maramara i tātarihia e mātou: 70% i ahu mai i ngā kōwhiringa tawhā ngoikore (rautaki, tere, whāngai, pupuhi hau). 30% anake i ahu mai i te āhua o te mīhini (te pakaru o te taputapu, te oma o te porowhita, te whakapiri). Nō reira, whakatikahia ngā tawhā i te tuatahi. Mena kua tutuki i a koe te Tohutohu 1–4, ā, kei te mau tonu te maramara, tirohia te mīhini.

Tohutoro Tere mō te Tohu Marara

Whakamahia tēnei ripanga hei tātaritanga i ngā pakaru me te whakatau i ngā whakatikatika matua:

Me pēhea te whakamahi i ēnei tohutohu e rima i roto i te raupapatanga

Mena kei te raru koe i te pakaru o te kiri i tēnei wā, whai i tēnei raupapa:

1. Hipanga 1: Tapahi paparanga-toru (Tohutohu 1) → Tirohia te CAM mō te taratara → te whakaotinga-haurua → te paahitanga o te whakaotinga. Ka whakaoti i te ~40% o te maramara.
2. Hipanga 2: Tomokanga/Putanga taputapu (Tohutohu 2) → Manatokohia he arawhata te Arataki-ki-roto/Arataki-ki-waho, ehara i te ruku. E whakaoti ana i te ~20%.
3. Hipanga 3: Tere me te whāngai (Tohutohu 3) → Tirohia te ripanga tohu, whakarerekētia te RPM, te whāngai rānei. Ka whakatau i te ~20%.
4. Hipanga 4: Tūnga pupuhi hau (Tohutohu 4) → Aro atu ki te tapahi, koki 45°–60°, pēhanga 0.5–1.0 pae. Whakaotia te toenga ~10%.
5. Hipanga 5: Tirohia te mīhini (Tohutohu 5) → Mēnā he tino tika ngā taahiraa 1–4, ā, kei te pakaru tonu. Tirohia te pakaru o te taputapu, te oma o te porowhita, te piri.

Mooni: 90% o ngā kaiwhakamahi ka whakaoti i te raruraru maramara mā te whai i ngā kaupae 1–4. 10% anake me pā ki ngā taputapu mīhini.

He aha i tautoko ai a DN-D5Z i tēnei rerenga mahi

Kua hangaia te hoahoa o DN-D5Z hei whakahaere tika i ēnei tikanga:

• Te tika o te tūnga ±0.01 mm: Ka rite tonu te mahi a ō tautuhinga tawhā ki tā te mea i whakaarohia
• Awhe 10,000–60,000 RPM: He ngāwari katoa ki te kimi i te wāhi pai mōu
• Pounamu mahi-teitei motuhake: Tere pumau, iti te oma, tautoko ana i te mana ara tika
• Hanganga konumohe katoa: Ko te anga pakari he iti ake te wiri kāore e hiahiatia

He māmā noa iho: Mā te DN-D5Z koe e whai wāhi ki te whakatinana i ēnei tikanga me te pono. Ko te tika o tō tawhā ka uru tika ki te kounga o te taha.

Me āwhina koe?

Mena ka tūpono koe ki ngā mata o te taputapu, ki te pakaru tonu rānei ahakoa te whai i ēnei mahi, whakapā atu ki te tautoko hangarau a Dentex . Tukua:

• Te waitohu me te āhua o te zirconia (kua oti te whakatō, kua oti rānei te whakatō)
• Momo whakaora (karauna, piriti, hononga whakatō)
• Te wāhi me te āhua o te pakaru (taratara, kōhatu, maramara nui)
• Ngā tautuhinga DN-D5Z o nāianei (tere o te miro, tere whāngai, taputapu)
• Whakaahua o te taha pakaru (mēnā ka taea, me whakanui ake)

I runga i ēnei mōhiotanga, ka taea e mātou te tautuhi i te raruraru me te tūtohu i tētahi whakatika i roto i ngā hāora, kaua i ngā rā.

Kia ora tō mira zirconia. Kia matatau ki ēnei tikanga e rima, ā, kāore he raruraru o te mahi mira.
