Me pēhea te manatoko i te papatahi o te pereti mata karāhe

Kua tono koe i tētahi pereti mata karāhe Karaehe 00. E ai ki te kaiwhakarato kua whakamanahia. Ka tae mai te pouaka. Ka hainatia e koe te rīhiti tuku.

E ono marama i muri mai, ka whakahaerehia e tō kaitirotiro kounga he tirotiro ā-aunoa, ā, ka kite ia kua neke te pereti ki waho o te ātete. Ka whakatuwhera koe i tētahi kereme. Ka tohu te kaiwhakarato ki te waitohu kei runga i tō rīhiti tuku.

He maha ake ngā wā ka puta tēnei āhuatanga i te mea e tika ana. Ehara i te mea nā te kore aro o ngā kaihoko — engari nā te mea kāore te nuinga o ngā kaihoko e mōhio he aha te mea hei tirotiro i mua i te pānga o te pene ki te pepa.

Mā tēnei aratohu koe e whakamārama ngā tikanga tuturu. Kāore he mahi uaua. Ka taea e koe te kawe i tēnei ki tō wāhi tirotiro āpōpō.

TL;DR

Ko ngā tohu papatahi (Tohu 00: ≤0.5μm/m, Tohu 0: ≤1μm/m, Tohu 1: ≤2μm/m) e tohu ana i ngā rahinga ine tūturu, ehara i te tapanga hokohoko. I mua i te hainatanga i tētahi rīhiti tuku: whakahaerehia te whakamātautau rīpene pepa hei kuaha tuatahi (5-10 meneti), kātahi ka mahi i tētahi inenga whatunga autocollimator tika (45-90 meneti). Ka tukuna ia pereti mata ZHHIMG® me te manatoko Tiamana Mahr 0.5μm, te whakaū taumata hiko WYLER Huiterangi, me te tirotiro whakawhiti inenga laser Renishaw — ka taea te whai i ngā whare wānanga ine ā-motu. Mena ka kitea he raruraru i roto i tō tirotiro hou, tuhia tonutia me ō ake raraunga ine i mua i te hainatanga.

He aha te 70% o ngā kaihoko o tāwāhi kāore e tirotiro i tā rātou pereti mata karāhe i te taenga mai

Māku e kōrero atu ki a koe te āhua o te mea e tupu ana i te taha whiwhi.

Ko te nuinga o ngā kaihoko o tāwāhi e whakawhirinaki ana ki te tiwhikete whakatikatika a te kaiwhakarato. E whakaaro ana rātou he pai te taiwhanga tuatoru, te tiwhikete ā-roto rānei a te kaihanga. Ka hainatia e rātou, ka neke atu.

Ko te raruraru: i hangaia taua tiwhikete i ngā rā, i ngā wiki rānei i mua i te taenga o te pereti ki tō papa. I te wā e kawe ana - inā koa ko te tuku ipu i runga i ngā huarahi moana - ka pāngia pea ngā pereti mata karāhe e te ru wera, te ahotea wiri, me te pānga tinana. Ko te pereti i wehe atu i te wheketere i roto i te manawanui ka tae atu ki tō whare i waho o te whakaritenga.

Kua kite ahau i ngā kaihoko e kite ana i tēnei i te wā e whakahaere ana rātou i tā rātou ake tirotiro autocollimator i te wā o te arotake whare. I taua wā, kua kati te matapihi tuku, kua pau te matapihi kereme, ā, kei a rātou he pereti $15,000 Grade 00 kāore e taea te whakamahi mō ngā mahi Grade 00.

Ehara te otinga i te paranoia. He tikanga tirotiro 20-meneti te roa ka taea te whakahaere me ngā taputapu taketake.

Te Mārama ki te Tau 00, te Tau 0, me te Tau 1: Te Tikanga Tuturu o aua Tau i roto i ngā Maikoroni

I mua i te taea e koe te whakaū i te papatahi, me mōhio koe ki tāu e rapu ana.

Kua tautuhia ngā tohu papatahi i roto i ētahi paerewa o te ao — DIN876, ASME B89, JIS, GB/T — ā, kotahi tonu te whakatakotoranga taketake o ēnei tohu katoa. Koinei te tikanga o ngā tohu:

Tukua ahau kia whakamāori i tēnei ki ngā tau o te ao tūroa.

Mō tētahi pereti paerewa 1000 × 630 mm (te rahi kaweake tino noa), ka taea e te Wāhanga 00 te rerekētanga papatahi katoa o te 1.5 μm puta noa i te mata katoa. Koia te 1/50 o te whānui o te toto toto whero tangata. Ka takiruahia e te Wāhanga 0 tēnei ki te 3 μm pea. Ko te Wāhanga 1 kei te 6 μm pea.

Koinei te mea e ngaro ana i te nuinga o ngā kaihoko: ko te whakatakotoranga kei ia mita o te roa o te mata, ehara i te rerekētanga katoa o te pereti.

Ki te hoko koe i tētahi pereti 2000 × 1000 mm, ka pā motuhake te ātete ki te taumata puta noa i ia mita rārangi o te mata. Ka tatauhia tō rerekētanga mōrahi e whakaaetia ana i runga i te rahi roa ake. Mō tētahi pereti 2000 mm, e titiro ana koe ki te 2.5 μm mō te Tau 00, 5 μm mō te Tau 0, me te 10 μm mō te Tau 1.

He tau ēnei ka taea e koe te ine. Ki te kī mai tētahi ki a koe he "tata ki te 3 maikoroni te rerekētanga" o tā rātou pereti 2000 mm Grade 00 — kei roto tēnā i ngā whakaritenga. Ki te mea rātou "tata ki te 8 maikoroni" — ko te rohe Grade 1 tēnā, ehara i te Grade 00.

Kia mārama ngā tau i mua i te hainatanga i tētahi mea.

Te Whakamātautau Rīpene Pepa: He Tikanga Papa Tere me Mōhio Ngā Kaihangarau Katoa

Ehara te whakamātautau rīpene pepa i teine tika. Engari he huarahi tere tēnei ki te hopu i ngā raruraru mārama i mua i te moumou taima ki te whakatū i tētahi autocollimator.

Anei te āhua o tana mahi.

Ka hiahiatia e koe: te pepa tā paerewa (70-80 gsm te pai), he mata pereti ma, me ngā ringaringa mārō.

1. Horoia rawatia te mata o te pereti ki te waipiro isopropyl. Ka hangaia he hononga teka e ngā paru katoa.

2. Tapahia ngā rīpene pepa kia 20 mm te whānui, kia 50-80 mm te roa.

3. Whakatakotoria ngā rīpene ki ngā wāhi rautaki puta noa i te mata o te pereti — ngā kokonga, waenganui, me ngā taha whakarara.

4. Ngana ki te neke i tētahi ine ine 0.5 mm ki raro i te rīpene pepa i raro i tōna ake taumaha.

Ngā mea e whakamātautauhia ana e koe: Ki te paheke te rīpene pepa i raro i tōna ake taumaha, he ātea te wāhi — arā, kua pēhia te mata o te pereti i taua wāhi e pā ana ki te rohe e karapoti ana. He tohu tēnei kei te kōpikopiko, kei te heke rānei te wāhi.

Herenga: Kāore e taea e tēnei whakamātautau te ine i te rerekētanga papatahi. Ka whakaatu noa i te pānga o te mata o te pereti ki te pepa puta noa i tōna whānui katoa. Ka taea e te pereti te paahi i tēnei whakamātautau, ā, kei waho tonu i te manawanuitanga o te Reanga 0.

He whai hua te whakamātautau rīpene pepa hei kuaha tuatahi. Ki te kore e angitu, ka whai wāhi tonu koe ki te whakakore, ki te pupuri rānei i te tuku. Ki te angitu, neke atu ki te autocollimator hei manatoko tuturu.

Te Tikanga Autocollimator: Te Ine a ngā Tohunga i te Papatahi o te Iti-Maikoroni

Koinei te wā e tino hira ai te manatoko.

Ka ine te autocollimator i te peka koki o te mata whakaata mā te whakaata i te hihi mārama kua kōpiripirihia, me te ine i te koki whakaata. Ka taea e ia te whakatau ki raro ki te 0.1 hekona-āwhata — arā, tata ki te 0.5 μm/m i runga i te mata karāhe.

Ngā taputapu e hiahiatia ana e koe:

• · Te autocollimator whatu (ko Taylor-Hobson, Mahr, Dietzgen rānei ngā waitohu ngaio noa)
• · He whakaata tika, he āpitihanga whakaata rānei
• · Tūnga whakairi pumau
• · Ngā mana whakahaere taiao (he kōrero anō kei raro)

Te tikanga ine:

1. Tukua te pereti kia tau ki te pāmahana rūma mō te iti rawa 4 hāora i muri i te tukunga. Ka aro te karāneti ki te huringa pāmahana i te 0.001 mm/°C pea. Mena ka tae mai te pereti he makariri, ā, he mahana tō toa, tatari.

2. Horoia rawatia te mata.

3. Whakatūria te autocollimator ki runga i tētahi tūāpapa pumau i tētahi pito o te pereti.

4. Tautuhia tō mata ine. Mō te pereti 1000 × 630 mm, he mata 5 × 5 (25 ngā pūwāhi ine) te paerewa. Ka whakamahia e ngā pereti nui ake he mata taurite.

5. Tangohia ngā pānui i ia whakawhitinga mata, me te neke i te whakaata i waenga i ngā pūwāhi.

6. Tuhia ngā pānui katoa. Tātaihia te tapeke o te pānui kua tohua (TIR) ​​puta noa i ngā pūwāhi katoa.

Mō te pereti Karaehe 00 1000 × 630 mm, kaua te tapeke o te TIR e neke ake i te 1.5 μm.

Ngā hapa e mahia ana e ngā kaihoko:

• · Te ine tonu i muri i te taenga mai o te pereti (te nekenekehanga wera)
• · Te whakamahi i tētahi autocollimator mamati iti te utu, kāore he whakatikatika kua manatokohia
• · E 3-4 noa iho ngā pānui e tangohia ana, kaua ko te matawai tika
• · Te kore aro ki te rohe taha — ka whakaaetia e ētahi paerewa te manawanui whakangāwari i roto i te 12 mm o te taha pereti, engari me tuhi e koe tēnei

Mena ka nui ake te pānui o tō autocollimator i te whakaritenga mō te māka, kei a koe he taunakitanga kua tuhia mō tētahi kereme. Kaua e hainatia te rīhiti tuku.

Te Pānui i te Tiwhikete Whakamātautau e Haere Mai Ana me Ia Pereti Mata ZHHIMG®

Ka tukuna mai he tiwhikete whakatikatika ki ia pereti mata ZHHIMG®. Anei me pēhea te pānui tika.

Ngā mea me puta ki te tiwhikete:

• · Ngā rahinga pereti me te tohu tohu
• · Tikanga ine e whakamahia ana (autocollimator, laser interferometer, CMM rānei — he tika katoa mēnā ka tika te mahi)
• · Rahi o te whatunga ine
• · Ngā āhuatanga taiao i te wā e ine ana (te pāmahana, te haumākū)
• · Ngā taputapu whakatikatika kua whakamahia, me ngā tau tiwhikete ka taea te whai
• · Ngā uara rerekētanga papatahi tūturu i inehia
• · Te rā o te whakatikatika
• · Paerewa tohutoro i whakamahia (DIN876, ASME B89, me ētahi atu)

Ngā mea hei manatoko tonu:

• · Ko te uara papatahi kua pūrongohia e ōrite ana ki te māka i tonoa e koe
• · Nō nā tata nei te rā ine (i roto i ngā marama 3-6)
• · E tohu ana te tiwhikete i ngā paerewa whakatikatika ka taea te whai

Ngā haki whero:

• · Kāore he āhuatanga taiao e whakaatuhia ana e te tiwhikete
• · Kāore he tohutoro ki te tikanga ine
• · Ngā taputapu whakatikatika kua rārangihia, kāore he tau tiwhikete ka taea te whai
• · "Mōhiotanga" kua whakahuatia, kāore he uara ine tuturu

Ka whakatikatikahia e ZHHIMG® ia pereti mā te whakamahi i ngā taputapu whakataunga Mahr 0.5 μm Tiamana me ngā taumata hiko WYLER Huiterangi, ā, ka taea te whai i ngā taputapu katoa ki ngā whare wānanga ine ine ā-motu tae atu ki te PTB (Tiamana) me te NIST (US). Kei roto i te tiwhikete whakatikatika ngā taputapu motuhake e whakamahia ana me tōna tau tiwhikete ka taea te whai.

Ngā Taipitopito e Toru e Ngarohia Ana e ngā Kaihoko — Me te Utu Ina Ngaro Ana rātou

Whai muri i ngā tau maha o te mahi tahi me ngā kaihoko i runga i te whakaae ki ngā pereti mata, kua kite ahau i ngā hapa e toru e puta ai ngā raruraru tino utu nui.

1. Te kore aro ki te whakaritenga pumau wera

He iti te kawe wera o te karāneti engari he kaha ki te ine i te whānui o te wera. Kua rerekē te pāmahana o tētahi pereti i inehia i te 20°C i roto i te wheketere, ā, ka tae mai ki te whare putunga i te 15°C. Ki te haina koe i tētahi pereti me te kore e tatari mō te taurite wera, kei te whakaae koe i tētahi pereti kāore i te mōhiotia tōna āhua.

Te utu mō te kore aro ki tēnei mea: Ka taea e te pereti Wāhanga 00 i roto i te rerekētanga wera 5°C te neke mā te 5 μm/m — tekau ngā wā o te manawanui Wāhanga 00.

2. Kāore i te tuhi i ngā pekapeka rohe taha

Ko te nuinga o ngā paerewa (DIN876, ASME B89) e tautuhi ana i te papatahi ki runga i te "wāhi whai hua" o te pereti, me te kore e tāpirihia he rohe 12 mm mai i ngā taha. Mena he angaanga taha, he tapahi whakarara rānei o te pereti, ka uaua haere tēnei.

Te utu mō te kore aro: Ka whakaae koe ki tētahi pereti kāore i eke ki te whakaritenga papatahi i te rohe pokapū ka taea te whakamahi, ahakoa te āhua nei kua eke te tiwhikete (i ine i ngā rohe taha).

3. Te whakaae "i runga i te manawanui" me te kore uara tūturu

Kāore i oti te tiwhikete e kī ana "Grade 00 — PASS" me te kore e whakarārangi i te inenga tuturu. Ko te pereti i te 0.48 μm/m he Grade 00. Ko te pereti i te 0.49 μm/m he Grade 00 anō hoki — engari he tata rawa atu tētahi ki te taha o te manawanui i tētahi atu.

Te utu o te kore aro ki tēnei: ​​Kāore he pūtake mō te aroturuki i te nekenekehanga i roto i te wā. Mena ka neke te pereti ki te 0.52 μm/m i muri i ngā marama e ono, kāore koe e mōhio ki te nui o tōna nekenekehanga.

Ngā Mahi a ZHHIMG® i mua i ia Tukunga: Tā Mātou Tikanga QC ā-Roto

Me mōhio koe ki ngā mea ka tupu i mua i te taenga atu o tō pereti ki tō tauranga.

E rua ngā whare hangahanga a ZHHIMG®, e 200,000 m² te rahi, me te papa kōhatu e 20,000 m². Ka tirotirohia ia pereti i mua i te tukunga:

1. Te ine mā te whakamahi i ngā taputapu taumira Mahr 0.5 μm Tiamana — te paerewa kotahi e whakamahia ana e te PTB me ngā taiwhanga ine ine ā-motu

2. Manatoko tuarua mā te whakamahi i ngā taumata hiko WYLER o Huiterangi hei whakaū i te peka koki

3. Matawai whatunga ā-aunoa mata-katoa — he iti rawa te whatunga 5 × 5 mō ngā pereti kei raro iho i te 1500 mm; he whatunga nui ake mō ngā pereti nunui rawa

4. Manatoko ine whakawhiti taiaho Renishaw UK mō ngā pereti Tau 00 katoa — e whakarato ana i te tirotiro whakawhiti motuhake o ngā raraunga papatahi

5. Manatoko pumau wera — ka inehia ngā pereti i muri i te pumau wera mō te 24 hāora te iti rawa i roto i te taiao whakahaeretia

6. Te whakaputa tiwhikete whakatikatika me ngā uara ine katoa, ngā raraunga taiao, me ngā taputapu ka taea te whai ki ngā whare wānanga ine ine ā-motu

Ehara tēnei i te paerewa ahumahi. He kotahi te inenga e tukuna ana e te nuinga o ngā kaiwhakarato, kāore he manatoko whakawhiti. Ka whakahaerehia e ZHHIMG® te manatoko takirua i runga i ia pereti Wāhanga 00 nā te mea ehara i te mea he pepeha noa iho te "kāore e taea e te pakihi tino tika te tono nui" — koinei te take e tono tonu ai ngā kaihoko pēnei i a GE, Bosch, me Rexroth i a mātou.

Ripanga Whakataurite: Ngā Tikanga Ine Papatahi

Mō te nuinga o ngā kaihoko e whiwhi ana i tētahi pereti paerewa 1000 × 630 mm, mā te manatoko autocollimator me tētahi whatunga 5 × 5 tika ka tika te mahi, ā, ka whai wā hoki ki te haumi.

Ngā Pātai Auau

He pēhea te papatahi o te pereti mata karāhe Grade 00 i roto i ngā tau tūturu?

Ko te taumata 00 e tohu ana i te rerekētanga papatahi mōrahi o te ≤0.5 μm/m. Mō te pereti 1000 × 630 mm, ka taea e tēnei te neke atu i te 1.5 μm te rerekētanga katoa puta noa i te mata. Mō te pereti 2000 mm, ka taea e tēnei te neke atu i te 2.5 μm. He inenga iti-micron ēnei e hiahia ana kia manatokohia e ngā taputapu tika.

Ka taea e au te whakamahi i tētahi taumata mīhini iti te utu hei tirotiro i te mata o te pereti karāhe?

Ka ine te taumata o te mīhini i te piko koki, ehara i te papatahi. Kāore e taea te kite i ngā pōuri ā-rohe, i ngā kōpiko rānei i te mata o te pereti — ko te piko whānui anake. Kaua e whakamahia te taumata o te mīhini hei taputapu manatoko papatahi. He mea whai hua hei tirotiro mēnā he papatahi tō pereti mata, kaua mēnā he papatahi.

Me aha ahau mēnā ka hē te pereti i tukuna mai i te whakatakotoranga papatahi?

Kaua e hainatia te rīhiti tuku. Tuhia te hapa ki ō ake raraunga ine (ngā pānuitanga autocollimator, ngā whakaahua, ngā āhuatanga taiao). Whakapā atu ki a ZHHIMG® me ngā taunakitanga kua tuhia. Ka whakahaerehia e mātou ngā kereme katoa me te whakatikatika anō, te whakakapi rānei i raro i tā mātou taurangi kounga.

Kia pēhea te roa o te ine i te autocollimator tika mō tētahi pereti 1000 × 630 mm?

Whakamaherehia mō te 45-90 meneti. Kei roto i tēnei ko te 20-30 meneti mō te manatoko i te pumau o te wera, 15-30 meneti mō te horoi me te whakarite i te mata, me te 15-30 meneti mō te ine tuturu puta noa i te mata 5 × 5. Mā te tere o te tukanga ka puta he hapa.

He aha te nekehanga wera, ā, he aha tōna pānga ki taku ine?

Ko te nekehanga wera ko te huringa o ngā rahi o te pereti i puta mai i ngā huringa pāmahana. Ka whānui te karāhe i te 0.001 mm ia nekehanga Celsius ia mita. Mena i whakatikatikaina tō pereti i te 22°C engari ko tō wāhi tirotiro he 19°C, ka rerekē te rahi 1000 mm mā te 3 μm — e ono ngā wā o te manawanui Grade 00. Tukua kia 4+ hāora mō te taurite wera i mua i te ine.

Me pēhea te whakahaere a ZHHIMG® i ngā kereme mēnā ka kitea he pereti kei waho i te taumata e whakaaetia ana?

Whakapā mai ki a mātou tonu me ō raraunga ine. Ka whakahaerehia e mātou he rangahau ā-roto, ka manatoko anō mā te whakamahi i tā mātou taiwhanga whakatikatika, ā, ki te whakaūtia kua kore te pereti e taea te whakamanawanui, ka tukuna e mātou he whakakapinga, he whakahokinga moni katoa rānei i runga i tā mātou utu tae atu ki te tuku whakahoki. Kei raro tēnei i tā mātou taurangi kounga kua tuhia, e tautokona ana e tā mātou pūnaha whakahaere kounga kua whakamanahia e ISO9001:2015.
