He taputapu tohutoro taketake ngā pereti mata karāhe i roto i te ine inenga. Ka mahi rātou hei raraunga ā-tinana matua mō te tirotiro, te whakatikatika, me te whakahāngai i roto ingā taiao hanga tino tikaKo ngā ahumahi pēnei i te rererangi, te hanga haurua-haurua, ngā pūnaha whatu, me te hangarau taputapu mīhini matatau e whakawhirinaki ana ki ēnei hanganga hei pupuri i te tika o te āhuahanga i ngā taumata maikoromita me te iti-maikoromita.

He rerekē ki ngā ripanga tohutoro whakarewa, he hanganga tioata pumau ā-taiao te karāhe, he iti rawa te ahotea o roto, he pai rawa ngā āhuatanga whakaiti wiri, ā, he pumau āhuahanga mō te wā roa. Nā ēnei āhuatanga ka waiho hei tetahi o ngā rauemi e whakamahia whānuitia ana mō ngā turanga ine tika puta noa i te ao.

I roto i ngā pūnaha hanga matatau, ka whakamahia e ngā whakahaere pēnei i a ZHHIMG te karāhe pango matotoru-teitei hei whakaputa pereti mata i hangaia mō ngā taiao ine tino pumau, he mea nui te auautanga me te whakahaere i te koretake.

1. Te Pūtaiao Rauemi i Muri i ngā Pereti Mata Granite

He toka mura te karāneti, he mea hanga tuatahi mai i te kuata, te feldspar, me te mika. Ehara i te mea tūpono noa tōna pai mō ngā mahi hangarau tika, engari i ahu mai i ōna āhuatanga hanganga moroiti.

1.1 Hanganga me te Pūmautanga o te Tioata

Ko te hanganga tioata honohono o te karāhe e whakarato ana i:

• Te kaha pēhi teitei
• Te iti rawa o te whakarerekētanga rapa i raro i te kawenga
• He iti te ahotea toenga ki te whakataurite ki ngā konganuku whakarewa
• He tino pai te pumau o ngā āhuatanga mō te wā roa

Kāore te karāneti e rerekē ki te maitai, ki te konumohe rānei, e rerekē ana te āhua, e rerekē ana rānei te āhua o te kiriuhi i raro i ngā kawenga inenga noa, ā, he mea tino pai mō ngā mata tohutoro.

1.2 Te Whanoke o te Wera

Ko te pumau o te pāmahana tētahi o ngā tawhā tino nui i roto i ngā pūnaha ine pāmahana.

Ngā āhuatanga noa o te karāhe pango matotoru:

• Tauwehenga o te whakawhānui wera: ~4–7 × 10⁻⁶ /°C
• Te ātete wera teitei
• Te kawe wera iti

Ko te tikanga o tēnei ka āta horapa ngā pikinga pāmahana mā roto i te rauemi, ka whakaiti i te hē o te nekehanga ā-rohe i te wā e ine ana.

He rerekē, ka taea e ngā hanganga maitai te whakaatu i ngā uara whakawhānui wera tae atu ki te 12 × 10⁻⁶ /°C, ā, ka kore e tino pumau mō ngā tono tohutoro tika.

1.3 Ngā Āhuatanga Whakamarumaru

He āhua tūturu te karāneti hei ārai i te wiri nā te rerekētanga o te hanganga o ngā kohuke. He mea nui tēnei āhuatanga i ngā taiao e whai ake nei:

• Kei reira ngā wiri o waho o te mīhini
• Ka mahi ngā Mīhini Ine Taurite (CMM)
• Ka mahia te ine whakawhiti laser

Ka marara te pūngao wiri mā roto i ngā rohe o roto o te kōpaka, kaua e tukuna puta noa i te hanganga.

2. Ngā Paerewa Tika mō ngā Pereti Mata Granite

Ehara ngā pereti mata karāhe i te pereti papatahi noa iho; he mea hanga, he mea manatoko hoki i raro i ngā paerewa ine taumaha o te ao.

2.1 Paerewa DIN 876 (Tiamana)

E tautuhia ana e te paerewa DIN 876 ngā tohu ātete papatahi:

Ko te tikanga ka aromatawaihia te papatahi mā te whakamahi i ngā taumata hiko, te ine ine laser, te autocollimator rānei.

2.2 ASME B89 (Te Hononga o Amerika)

E whakamārama ana a ASME B89:

• Ngā whakaritenga mō te koretake o te ine
• Ngā tukanga whakatikatika
• Te whai i ngā paerewa ā-motu

He whānuitia te whakamahinga i roto i ngā pūnaha hanga rererangi me te ārai.

2.3 ISO 9001 / Ngā Pūnaha Kounga e hangai ana ki te ISO

Ahakoa kāore te ISO 9001 e tautuhi tika ana i ngā tūponotanga ine ine, e whakahaere ana i:

• Ngā pūnaha whakahaere kounga
• Te whai i te whakatikatika
• Ngā whakaritenga whakahaere tukanga

Me whakarite e ngā kaihanga e mahi ana i raro i ngā anga ISO te āheinga ki te whakahoki anō me ngā mekameka whakatikatika kua tuhia.

3. Te Hangarau Papatahi me ngā Tikanga Ine

Ko te papatahi te tawhā matua o tētahi pereti mata. Heoi, ehara te papatahi i te ine ira kotahi engari he āhuatanga āhuahanga kua ahu mai.

3.1 Ngā Tikanga Ine

Ko ngā tikanga noa ko:

• Ngā taumata hikohiko (hei tauira, ngā pūnaha WYLER)
• Te ine ine i te reera (ngā pūnaha Renishaw)
• Ngā Autocollimator
• Te whakataurite ā-mīhini mā te whakamahi i ngā tapa tika matua

Ka whakaurua mai e ia tikanga ngā takoha rerekē o te koretake.

3.2 Ngā Pūtake Hapa i roto i te Ine Papatahi

Ngā mea matua e pā kino ana ki te koretake:

• Ngā pikinga pāmahana puta noa i te mata
• Te āheinga ki te whakahoki i te tirotiro
• Te wiri iti i puta mai i te rere o te hau
• Te rerekētanga o te whakahaere a te kaiwhakahaere
• Te koretake o te whakatikatika taputapu

I roto i ngā taiwhanga papai, ka taea te whakahaere i te koretake o te ine i roto i ngā taumata iti iho i te micron.

3.3 Te Whanoketanga Pūmautanga mō te Wā Roa

Kāore i rite ki ngā pereti whakarewa, kāore te karāneti e whakaatu ana i:

• Te whakangāwari i te ahotea
• Te whakarerekētanga ngokingoki kirihou
• Te whakapōturitanga i puta mai i te ngenge

Nā tēnei ka pai ngā pereti mata o te karāhe mō ngā tono tohutoro mō te wā roa, me te kore e whakamahia anō kia maha ngā mīhini.

4. Ngā Whakamahinga Ahumahi o ngā Pereti Mata Granite

He tūāpapa ngā pereti mata karāhe i roto i ngā ahumahi hangarau teitei maha.

4.1 Ngā Mīhini Ine Taunga (CMM)

Whakamahia hei:

• Rārangi tohutoro turanga
• Pūhara whakatikatika mīhini
• Te turanga tirotiro i ngā mea mahi

4.2 Ngā Taputapu Ārahi-Haumaru

Kei roto i ngā tono:

• Ngā pūnaha whakahāngai angiangi
• Ngā wāhanga tūnga tuhi
• Ngā papaaho ine ine tirotiro

4.3 Te Whakatikatika i ngā Utauta Mīhini Tika

Whakamahia mō:

• Te whakarite mīhini CNC
• Whakatikatika aratohu rārangi
• Manatoko oma o te porowhita

4.4 Ngā Pūnaha Whatu me te Taiaho

Ngā turanga karāhe e tautoko ana:

• Ngā ine whakawhiti laser
• Ngā paepae whakahāngai whatu
• Ngā pūnaha huihuinga photonics

5. Granite me ngā Rauemi Rerekē

Ko tētahi whakataunga hangarau nui ko te whiriwhiri rauemi mō ngā turanga tohutoro.

He pai ake te mahi a te karāhe i ngā momo konganuku kē atu i roto i ngā taiao ine ine.

6. Ngā Whakaarohanga Hanga Ahumahi

Ko ngā pereti mata karāhe kounga teitei e hiahia ana ki ngā taiao hanga whakahaere:

• Ngā tukanga whakapiri tika
• Te waru me te huri i ngā wāhanga maha
• Whakahaere pāmahana taiao (20°C ±1°C noa)
• Ngā huringa whakaū i te whakamamae i te ahotea

Ka whakauruhia e ngā kaihanga matatau pēnei i a ZHHIMG ngā pūnaha mīhini nui e kaha ana ki te whakaputa pereti neke atu i te maha mita te roa, me te pupuri tonu i te mana papatahi o te taumata micron.

Whakamutunga

Ko ngā pereti mata karāhe tonu te tūāpapa o te ine tika o ēnei rā nā te mea he huinga ahurei o te pumau ā-mīhini, te kore e pā ki te wera, me ngā āhuatanga whakaiti wiri. Ina honoa ki te piripono ki ngā paerewa o te ao pērā i te DIN 876 me te ASME B89, ka whakaratohia e ngā pūnaha e hangai ana ki te karāhe te turanga mō te hanganga ine pono, ka taea te whakahoki, me te whai.

I te haere tonu o te tika o te hanga ki ngā taumata tauine nanometer, ka noho tonu te karāhe hei rauemi whakauru nui i roto i te pūnaha ine ine o te ao.
