I te wā e whiriwhiri ana i tētahi rauemi hanganga mō tētahi mīhini tino tika, ehara i te mea ko te pakari anake te mea e whiriwhiria ana. Engari ko te pumau o te wera, te whakaiti i te wiri, te pumau o ngā āhuatanga mō te wā roa, me te utu katoa o te mana pupuri. E toru ngā rauemi e kōrerohia ana: te karāhe tūturu, ngā uku hangarau, me te whakarewanga kohuke. He wāhi tō ia rauemi. Engari ko te mārama ki te wāhi e pai ai ia rauemi—me te wāhi e kore e pai ai—koinei te rerekētanga i waenga i tētahi mīhini e pupuri ana i ngā hautekau o te maikorona me tētahi e kore e tutuki i ngā whakaritenga i roto i te tau.
Te Pātai Pūmautanga Wera
Ko te rere wera te kaipatu puku o te tika. Ahakoa he iti noa te maikoroni mō ia mita mō ia nekehanga Celsius, ka kore e whai hua te CMM $500,000 mō ngā mahi manawanui nui, ka taea e te turanga mīhini e whānui ana, e whakawhāiti ana rānei.
Ko te karāhe taiao tētahi o ngā tauwehenga whakawhanui wera (CTE) iti rawa, ā, tino matapaetia hoki i waenga i ngā rauemi hanganga—i te nuinga o te wā kei waenganui i te 4.6 ki te 9 × 10⁻⁶/°C. He tino rerekē tōna ātete wera: he rauemi "puhoi" te karāhe e iti ana te tauhohe ki ngā huringa pāmahana taiao, e waiho ana hei paerewa koura mōngā mīhini ine taungame ngā papaaho ine. I ZHHIMG®, ka eke te mātotoru o tā mātou karāhe pango ZHHIMG® ki te ≈3100 kg/m³—he teitei ake i te nuinga o ngā karāhe pango o Ūropi me Amerika—e whakarei ake ana i tōna papatipu wera me tōna pumau.
Ko ngā uku i hangaia, inā koa ko te silicon carbide (SiC) me te konumohe waikura (Al₂O₃), he iti ake ngā uara CTE (3–5 × 10⁻⁶/°C) me te kawe wera pai ake (10–30 W/mK ki te whakataurite ki te 1–3 W/mK o te karāhe). Ko te tikanga ka tere ake te whakamarara o ngā uku, engari he uaua ake te mīhini, ā, he nui ake te utu ki te whakaputa i roto i ngā rahi hanganga nui.
Ko te whakarewanga kohuke (e kiia ana ko te raima polymer, ko te karāneti epoxy rānei) he CTE tata ki te 8–12 × 10⁻⁶/°C—he teitei ake i te karāneti tūturu, ā, he uaua ake te matapae nā te nui o te kapia epoxy. Heoi, he nui te ātete wera o te whakarewanga kohuke, e ātete ana i ngā piki me ngā heke o te pāmahana, ā, e whakarato ana i te taiao pumau mō ngā mahi CNC huringa-rahi e whakaputa ana i te wera nui e ngā motuka.
Te Tauwehe Whakamarumaru
Ko te wiri te hoariri o te whakaotinga mata me te tika o te ine. I roto i te mira CNC tere-teitei, ka puta te haruru. I roto i te tirotiro semiconductor, ahakoa ngā wiri iti rawa ka arahi pea ki ngā hapa ine. Ka whakamararatia e te karāhe taiao ngā wiri 5-10 ngā wā he nui ake te whai hua i te rino maka. Ko tōna hanganga tioata e whakarato ana i te whakamāmā ā-roto e whakaiti ana i te haruru mīhini me te whakapai tika i te whakaotinga mata me te roa o te taputapu. Heoi, ka neke ake te whakamāmā i te maka kohuke. Ko te hanganga kapia epoxy i roto i te maka kohuke ka mimiti i te wiri he pai ake te whai hua i te hanganga kōhatu tioata noa. E ai ki ētahi puna he 5 ki te 10 ngā wā teitei ake te ōwehenga whakamāmā i te karāhe taiao, i runga i te ōwehenga kapia-ki-te-whakakotahi.
He rerekē, he ngoikore te ōwehenga whakamākū o ngā uku—he 0.01–0.02 noa iho te ōwehenga whakamākū, ki te whakaritea ki te 0.03–0.05 o te karāhe me te 0.04–0.08 o te whakarewanga kohuke.
Ko te akoranga whaihua: Mena kei roto i tō tono he papatipu tauutuutu tere-teitei—pēnei i te wiri PCB e peia ana e te motuka raina, te hononga haurua-ira rānei—ko te whakarewanga kohuke pea te kōwhiringa pai rawa atu hei whakaiti i te wā taunga. Mena kei te hanga koe i ngā taputapu taiwhanga tino tika, i ngā CMM, i ngā papa ine whatu rānei, he mea nui ake te pumau o ngā āhuatanga i roto i ngā tau i te whakaiti i te wā tapahi, ko te karāhe totoka tonu te rauemi e pai ake ana.
Ngāwari o te Hanga me te Hoahoa
Koinei te wāhi e tino rerekē ai ngā rauemi e toru.
Ka keria te karāneti, kātahi ka hurihia kia āhua rite. Ahakoa ka tutuki te papatahi teitei rawa atu—ka tukatukahia e ZHHIMG® te karāneti ki te papatahi taumata nanometer—he uaua ki te whakauru i ngā āhuatanga uaua o roto. Ko te tāpiri i ngā whakaurunga miro, i ngā awa whakamatao rānei, me keri me te hono nui. Ko tō mātou kaha ki te tukatuka i ngā wahi takitahi tae atu ki te 20 mita te roa, 4000mm te whānui, me te 1000mm te matotoru—mā te whakamahi i ngā mīhini huri Nantec tino nui e whā, neke atu i te $500,000 USD te utu mō ia mīhini—e whakaatu ana i te tauine ka taea te whakatutuki me te karāneti tūturu.
He tukanga whakarewa te whakarewanga kohuke. Mā tēnei ka taea te "hoahoa whakauru": ka taea te whakarewa tika i ngā whakaurunga miro, ngā paipa, me ngā awa taura ki roto i te hanganga. Ka taea e ngā kaihoahoa te hanga i ngā hanganga tuwhera, i ngā whakakaha rānei e kore e taea te mīhini mai i te kōhatu totoka. Mā te whakarewa i ngā wāhanga maha ki roto i te turanga kotahi, ka whakaitihia e koe te maha o ngā hononga pūtu - ka whakapai ake i te pakari o te mīhini katoa.
Ko ngā uku te mea tino pakeke (Mohs 8–9.5) me te ātete ki te pakaru, engari me huri taimana motuhake me te whakamahana pāmahana teitei i runga ake i te 1200°C hei hanga. He iti noa te rahi o ngā wāhanga uku hanganga, ā, he nui ake te utu.
Te Whakataunga
Kāore he whakautu kotahi e tika ana mō te katoa. Ko ngā kaihanga taputapu nui ka whakamahi i ngā rauemi e toru, e rite ana ki te tono, kaua e whiriwhiri i tētahi hei paerewa whānui:
- Kōwhiria te karāhe tūturu mō ngā papaaho ine ine, ngā turanga CMM, ngā mata hau, me ngā paepae whatu kei reira ngā maikorona o te rere i roto i te tekau tau te mea e ngana ana koe ki te ārai.
- Kōwhiria te whakarewanga kohuke mō ngā anga taputapu mīhini me ngā turanga hanganga e hiahia ana kia whakarewaina kia rite ki ngā āhua uaua, kia mimiti hoki i te wiri tapahi.
- Kōwhiria ngā uku mō ngā tono e hiahia ana ki te tino pakeke, te ātete ki te kakahu, te tere rānei o te tohatoha wera i roto i ngā āhua kiato.
I ZHHIMG®, ka hangaia e mātou ngā mea e toru—te karāhe tino tika, te uku tino tika, me ngā wāhanga whakarewa kohuke—nā te mea kāore mātou e whakapono ki tētahi otinga kotahi te rahi e pai ana mō te katoa. Ko tā mātou karāhe pango ZHHIMG®, me tōna mātotoru 3100 kg/m³ me ōna āhuatanga ā-tinana pai rawa atu, kei te noho tonu hei paearu mō ngā tono e kore e taea te whiriwhiri i te pumau tino tika. Engari e mōhio ana hoki mātou he wāhi tō te whakarewa kohuke me ngā uku i roto i te pūnaha tino tika. Ko te mea nui ko te mōhio ko tēhea rauemi e whakaoti ana i tō raruraru.
