Ngā Tino Tauwhaitanga Atu i ngā Tikanga Tuarangi Tuarangi

Te Mārama ki te Lapping: Ngā Matapae me te Tūranga ki ngā Taumira Rawa o ngā Whakamahinga

He aha te Lapping? Te Aronga Matua me te Kaupapa ki te Whakapaipai Mata

Ko te lapping he ara tino whaihua ki te tango i ngā wāhanga iti rawa o te matēriahi mai i ngā mata kia rite ai ki ngā mātāpae hoki, he iti ake i te 0.1 microns Ra. Ko te mea e wehe ana i ia arataki tāraiwa rānei ko te tikanga e mahi ana, arā nā ngā pārtihiri toharuā, pērā i ngā tapuwae, ngā pārtihiri aluminium oxide, i ngā pārtihiri silicon carbide e takotoria ana ki roto i tētahi rewharewha motuhake i waenganui i te wāhanga e mahia ana me te papa lapping e pororangi ana. Ko te tikanga katoa e tango ana i ngā karapiko ā-huri noa ka neke haere ngānei ki ngā tātaitanga maha, ka taea ai te heke iho i te rereketanga o te mata ki raro ake i te 0.1 microns Ra. He nui ake te maroke i ngā tikanga tāraiwa tūmatanui. Mō ngā ahumahi e hiahiatia ana kia tūpono tika ngā wāhanga e hāngai ana ki te pēhi, pērā i te hanga wāhanga mō ngā rererangi, i te waihanga i ērā hononga rebar e whakamahia ana i ngā kaupapa hanga, ka nui te take o te lapping. E horo ana ēnei tāpoi ki tēnei tikanga nā te mea he herekore te herekore e hiahiatia ana mō te poka poka me te tika tino o ngā wāhanga ina huinga atu.

Me Āhua ai te Lapping: Ngā Mea Kōpū, Te Pēhanga, me ngā Tōpana Arataki

E toru ngā āhuatanga e whakahaere ana i te tango mātai:

• Te whiriwhiri i ngā mea kōpū : Ko ngā pārtihikara diamanti (5–40 µm) te nuinga o ngā wā e whiriwhiria ana mō te hēra taraiwa nui pea nā te kaha me te tino ū ki te papa
• Pēhi Konekiti : Ka pupuri i waenganui i te 0.1–0.25 MPa kia āhua kotahi te tere tango me te pono o te mata
• Te nekenga parahuka : Ko ngā huringa 50–150 RPM ki te 2–10 mm te wehi e aukati ana i ngā kōhao iti

Ko te arataki "kōpū anuanu tokotoru" e whakaae ana i te tango mātai i ngā tere 0.8–3 µm/min i te wā e pupuri ana i te ±0.3 µm te rite o te paparua i runga i ngā tapawhā 150mm—mea nui kia tiakina te hononga paku tūpono i ngā kōpae rebar.

Ngā Momo Lapping Matua Whanui me Ō Rātou Whakamahinga Hātepe

Momo	Mōhiotanga	Ngā Tūhinga Whakamahinga Matua	Te Toleransi Kua Eke
Taha-tahi	Ko te mata kākara tahi anō	Ngā papa vāvā, ngā porowhita ine	whangetanga ±0.25 µm
E rua ngā taha	Rua ngā mata e mahi ana tahi	Ngā wafer silicon, ngā pakipaki	te ŋiringa ōrite 0.05 µm

Kāo e neke ana te keri	Ngā paparanga kua whakauria te diamanti	Ngā taputapu karbiti, ngā taonga huna mō ngā mahi kirurgi	±0.1 µm anuanu

Kei te whanaketia haere te whakamahi i te keri kia rua taha i te hanga koupene pūpahi kia eke ki te <0.2 mm/m anuanu mā te 50mm whenua, kia tiakina ai te whaihua o ngā takotoranga marangai.

Te Whiwhi i te Pae Tino Pai me te Anuanu Mā te Keri Matatau

Te Eke Ki Te Māmāiti Iho I Te Rangi O Te Micron I Taunaki Ake I Te Keri Me Te Hōni

Ka taea e te taraiwa i te rangi nei te whakarereke i te pātiki ki raro ake i te 0.1 micrometers, e tino pai ake ana i te kōhatu e 0.4 micrometers Ra, i te honinga rānei e 0.2 micrometers Ra mō ērā o ngā tono tino pono. He aha te mea e āwhina ai i tēnei kaupapa? Nō te aronga ki te mahi o te tukanga me te paraihe e toru-tinana. Ka nekeneke ngā paraihe tapuwae puta noa i tēnei tukanga, ā, ka wareware haere i ērā itiiti iti. I kitea hoki e ngā rangahau hou i te tau 2024 he mea hou. Ina mahi ana ki ngā wāhanga rino, ko te whakamahi i ngā paraihe tapuwae kua honoa ki te resin i te nuinga o ngā paraihe iron oxide tawhito, ka pakaru te uara Ra mai i te toru haurua. Ko te whanaketanga pēnei ka whakamārama i te take e huri ana ngā kaihangahanga anuanu ki ngā tikanga taraiwa hou i ēnei rā.

Ngā Hua Pūtake e Pakari Ana i te Kiko o te Rangi: Te Rāwekenga o te Paraihe, te Tere, me te Tā

E toru ngā utanga matua e whai whakaaro ana i ngā putanga taraiwa:

• Te rahi o te rāwekenga paraihe : Ka taea e ngā tapuwae nano-āhuarangi (0.1–5 µm) te whakaputa i ngā kiko pīataata
• Te tere whakarerenga : Ko te tauwātea whai hua o 0.5–3 m/s ka whakaiti i te rerekētanga o te wera
• Pēhi Konekiti : Ko te 10–30 kPa e whakanui ana i te wehenga tika o te matū me te kaha o te mata

Ko ngā horahora horahora iti ake i te wāhi kotahi me te whakahaere tohu pēhi e whakaiti ana i te mate i raro i te mata 42% i ngā waahanga steele kākahu tōkangia tēnā i ngā punaha uta-tū.

Tauānga Kōrero: Ngā Tono Tikanga Matatau ki te Whakawhanaketanga o ngā Coupler Rebar

Meitītia ana ngā coupler rebar i ngā noho maru kei raro i ±0.005 mm mā runga i ngā mata tarau kia manawapa ai te ahurea o raro i ngā uta rū whenua. I te nuinga o te kaiwhakanao, i te 78% te itinga i ngā take tarau tarau i muri i te neke mai i te CNC grinding ki te lapping aunoa, ā, i tino pai ai te 0.07 µm Ra mō ngā coupler parahi kaha teitei.

Whakatairitea i te Mahi Maru: Lapping vs. Ngā Huarahi Miihini Tuku Iho

Ko te lapping e whiwhi ana i te λ¼/4 papa hiko (te wehe 0.00006 mm) mā te whakamahi i ngā kaitiaki taonga e whakarārangi ana ake rātou anō me ngā porotiti e āki ai te viscosity. I te tuarangi, e tino herekau ana ngā tikanga tāpahi me te karapoti ki te pupuri i te papanui pai ake i te 0.01 mm i runga i ngā roa 150 mm nā te parerā o te taputapu, pērā i te whakaatu i ngā tohu tūmatanui e whakāro ana i te nuinga o ngā pūnaha tāpahi neke atu i te 50.

Ngā Utu mō te Tere Tangohanga Mātai: Whai Mātauranga Tēnei i te Tere i ngā Tikanga Lapping

Lapping vs. Grinding vs. Honing: Te Maru, Te Whakahaere, Me te Pono

Kua tango te whakapērānga i te matū he tere, neke atu i te haurua ki te inia kūpapa kotahi ia hēkona, kei te honingia hoki i te tere iti ake i waenganui i te 0.1 me te 0.3 inia kūmara ia hēkona. Engari ko te lapping he mea rerekē. Heoi anō ko te mea nui he mea tika anō i te kore e hohoro, ka tango i te iti ake i te 0.02 inia kūmara ia hēkona. Ka tika te utu ina titiroa matou ki te pātata. Nā te mea he tere rawa tana, ka taea e ngā pārtihikara abrasive te whakatika i ēnei herenga itiiti i ngā mata e hapa ana i ētahi atu tikanga. Ka heke ngā ine mata i muri i te lapping ki waenganui i te 0.01 ki te 0.1 micrometers, e tohu ana i te mutunga pai ake i te toru hauwhā nui ake i te mutunga e angata ana te grinding. Ina hangaia ngā wāhanga pērā i ngā rauemi optikai kounga teitei, ngā injini pūrua tikanga tikanga ranei, kei te pirangi ngā kaihanga kia pau te wā kia tino tika ai.

Te Tūtohu Whakatau: Ngā Tere Tangohanga Mātai i runga i ngā Tikanga Mahi Mātai

I tētahi rangahau 2023 i Taiao i whakamārama i te utu: i tino keri te keri i te MRR o 0.02 mm³/min, i te wā e pupuri ana i te 0.05 µm papaitanga, ā, ko te keri i hoatu te MRR o 0.5 mm³/min engari me te 0.3 µm pāpātanga papaitanga. Kei te mārama tēnei arataki 25:1 ki ngā kaihanga e hiahiatia ana ngā inenga micron-level kia whiriwhiri mō ngā tikanga mōrearea, he aha pea ka tino tūmata.

Te Paradox o te Ahumahi: He Tikanga Māmā noa kia Nui Ake te Tūmata

He wā nui ka pāngia e ngā waehoro matua te iti rawa o ngā mahi. Ko ngā parirau turuma jet e hiahiatia ana te ūnuinga mata o 0.01 µm ka pau ai te wā 3–5 nekehanga roa ake ki te keri i te keri, ā, āe, ka whakaatu i te iti ake o ngā hapa i muri i te mahi mātai 90%. E whakaatu ana ngā rangahau mai i te Society of Manufacturing Engineers i te whakapai ake o te 14% i te tika mō ia 10% teitei i te MRR mō ngā ara here.

Te Taurite i te Whai Wāhitanga me te Inenga i te Whanonga Rebar

Kua whai hua te lapping hou i te take kōrero-ūnga mā te whakahaere aunoa me te whakahaere i te wā poto. I te whakamātautau 2024, i kitea he wātiu 30% āhua tere ake ngā wā takirua trakihana ki te whakapai ake i te rere o te parahi me te tautohe i te tohatoha, i te wā e pupuri ana i te noho wehe tata ki te ±0.005 mm e hiahiatia ana mō ngā hononga hanganga e āki ai i ngā rū whenua. Ānini tēnei kaupapa i te arataki ASME B1.1 kāore i tino whakaroa i te kōtaha o te whakaputa.
