Xa ukhetha izinto zokwakha umatshini ochanekileyo kakhulu, ukhetho alukho nje malunga nokuqina. Luphathelele ukuzinza kobushushu, ukudambisa ukungcangcazela, ukuthembeka kwexesha elide, kunye neendleko zizonke zobunini. Izinto ezintathu zilawula incoko: i-granite yendalo, i-ceramics eyenziwe ngobunjineli, kunye nokuphoswa kweeminerali. Nganye inendawo yayo. Kodwa ukuqonda apho nganye igqwesa khona—nalapho ingena khona—ngumahluko phakathi komatshini ophethe ishumi le-micron kunye nomatshini ophuma ngaphandle kwe-specific kungakapheli unyaka.
Umbuzo Wokuzinza Kobushushu
Ukushukuma kobushushu bububulali obungabonakaliyo bokuchaneka. Isiseko somatshini esandayo okanye esinciphayo nokuba zii-microns ezimbalwa ngemitha nganye ngeqondo leCelsius singenza i-CMM eyi-$500,000 ingasebenzi kumsebenzi wokunyamezelana okuphezulu.
I-granite yendalo inenye yezona coefficients ziphantsi neziqikelelweyo zokwandiswa kobushushu (CTE) phakathi kwezinto zokwakha—ngokuqhelekileyo zikwisithuba se-4.6 ukuya kwi-9 × 10⁻⁶/°C. I-inertia yayo yobushushu ikhethekile: i-granite yinto "ecothayo" ephendula kancinci kutshintsho lobushushu olungqongileyo, nto leyo eyenza ibe ngumgangatho wegolide weoomatshini bokulinganisa abalungelelanisiweyokunye namaqonga e-metrology. Kwi-ZHHIMG®, i-granite yethu emnyama ye-ZHHIMG® ifikelela kuxinano lwe-≈3100 kg/m³—ngaphezulu kunezinye ii-granite ezimnyama zaseYurophu naseMelika—nto leyo ephucula ngakumbi ubunzima bayo bobushushu kunye nozinzo.
Iiceramics ezenziwe ngobunjineli, ngakumbi i-silicon carbide (SiC) kunye ne-aluminium oxide (Al₂O₃), zibonelela ngamaxabiso aphantsi nangakumbi e-CTE (3–5 × 10⁻⁶/°C) kunye nokuqhuba okuphezulu kobushushu (10–30 W/mK xa kuthelekiswa ne-granite's 1–3 W/mK). Oku kuthetha ukuba iiceramics zinokususa ubushushu ngokukhawuleza, kodwa kunzima kakhulu ukuzisebenzisa kwaye zibiza kakhulu ukuzivelisa ngobukhulu obukhulu besakhiwo.
Ukwenziwa kweminerali (ngamanye amaxesha kuthiwa yi-polymer concrete okanye i-epoxy granite) kune-CTE emalunga ne-8–12 × 10⁻⁶/°C—iphezulu kunegranite yendalo kwaye ayiqikeleleki ngenxa yomxholo we-epoxy resin. Nangona kunjalo, ukwenziwa kweminerali kunika i-inertia ephezulu yobushushu, kuxhathisa ukuguquguquka okukhawulezileyo kobushushu kwaye kubonelela ngendawo ezinzileyo yokusebenza kwe-CNC yomjikelo ophezulu apho iimoto zivelisa ubushushu obukhulu。
Into Ebangela Ukudamba
Ukungcangcazela lutshaba lokugqitywa komphezulu kunye nokuchaneka kokulinganisa. Kwi-CNC milling ekhawulezayo, kubangela ingxolo. Kuhlolo lwe-semiconductor, kwanokujikeleza kwe-microscopic kunokukhokelela kwiimpazamo zokulinganisa. I-granite yendalo ichitha ukungcangcazela ngokuphindwe ka-5-10 ngempumelelo kune-cast iron. Isakhiwo sayo se-crystalline sinika ukufutha okungokwemvelo okunciphisa ukungcangcazela komatshini kwaye kuphucula ngokuthe ngqo ukugqitywa komphezulu kunye nobomi besixhobo. Nangona kunjalo, ukufutha kweminerali kuthatha inyathelo eliya phambili ukufutha. I-epoxy resin matrix kwi-mineral casting ifunxa ukungcangcazela ngokunempumelelo ngakumbi kunesakhiwo selitye se-crystalline kuphela. Eminye imithombo ixela umlinganiselo wokufutha ngokuphindwe ka-5 ukuya ku-10 ngaphezu kwe-granite yendalo, kuxhomekeke kumlinganiselo we-resin-to-aggregate。
Ngokwahlukileyo koko, iiceramics azinawo umswakama ofanelekileyo—ngokuvamile umlinganiselo womswakama ongu-0.01–0.02 kuphela, xa kuthelekiswa nomlinganiselo wegranite ongu-0.03–0.05 kunye nomlinganiselo weminerali ongu-0.04–0.08.
Isifundo esisebenzayo: Ukuba isicelo sakho siquka ubunzima obuphindaphindeneyo obukhawulezayo—njenge-PCB drill eqhutywa yi-linear motor okanye i-semiconductor bonder—ukuphoswa kweminerali kunokuba lolona khetho lubalaseleyo lokunciphisa ixesha lokuzinza. Ukuba wakha izixhobo zelebhu ezichanekileyo kakhulu, ii-CMM, okanye amaqonga okulinganisa okukhanya apho uzinzo lobukhulu ngokuhamba kweminyaka lubaluleke ngaphezu kokufuma ngexesha lokusika, i-granite eqinileyo ihlala iyeyona nto ikhethwayo.
Ukuvelisa kunye nokuguquguquka koyilo
Kulapho ke ezi zinto zintathu zahluka khona kakhulu.
Igranite iyagrunjwa ize emva koko igutywe ukuze ifane. Nangona ifikelela kwindawo ephezulu kangangoko—i-ZHHIMG® icubungula igranite ukuya kwindawo ethe tyaba kwinqanaba le-nanometer—kunzima ukufaka iimpawu zangaphakathi ezintsonkothileyo. Ukongeza ii-inserts ezinemisonto okanye iitshaneli zokupholisa kufuna ukubhola kunye nokubopha okunzima. Amandla ethu okucubungula iziqwenga ezilodwa ukuya kuthi ga kwiimitha ezingama-20 ubude, ububanzi obuyi-4000mm, kunye nobukhulu obuyi-1000mm—sisebenzisa oomatshini abane abakhulu beNantec bokugrumba, nganye ixabisa ngaphezulu kwe-$500,000 USD—ibonisa ubungakanani obunokufikelelwa ngegranite yendalo.
Ukuphoswa kweeminerali yinkqubo yokuphoswa. Oku kuvumela "uyilo oludibeneyo": ukufakwa kwemisonto, imibhobho, kunye nemibhobho yekhebula kunokuphoswa ngqo kwisakhiwo. Abayili banokwenza izakhiwo ezingenanto okanye ukuqinisa okunemiqolo okungenakwenzeka ukuba kuphoswe ngelitye eliqinileyo. Ngokuphoswa iindawo ezininzi kwisiseko esinye se-monolithic, unciphisa inani lamalungu adibeneyo—ukuphucula ngakumbi ubulukhuni bomatshini ngokubanzi.
Iiseramikhi zinobunzima obuphezulu (Mohs 8–9.5) kwaye ziyamelana nokuguguleka, kodwa imveliso ifuna ukugaywa kwedayimani okukhethekileyo kunye nokutshiswa kobushushu obuphezulu ngaphezu kwe-1200°C. Izinto zeseramikhi ezakhiweyo zihlala zilinganiselwe ngobukhulu kwaye zibiza kakhulu.
Isigqibo
Akukho mpendulo ifanelekileyo kuzo zonke. Abavelisi bezixhobo abazimiseleyo badla ngokusebenzisa zonke ezi zinto zintathu, ezihambelana nesicelo endaweni yokukhetha enye njengomgangatho oqhelekileyo:
- Khetha i-granite yendalo kwiiplatifomu ze-metrology, iziseko ze-CMM, iindawo ezithwala umoya, kunye neebhentshi ze-optical apho ii-microns zokuntywila ngaphezulu kweshumi leminyaka yinto ozama ukuyithintela.
- Khetha ukuphoswa kweeminerali kwizakhelo zezixhobo zomatshini kunye neziseko zesakhiwo ezifuna ukuphoswa kwiimo ezintsonkothileyo kwaye zifunxe ukungcangcazela kokusika.
- Khetha iiseramikhi xa ufuna ukuqina kakhulu, ukumelana nokuguguleka, okanye ukusasazwa ngokukhawuleza kobushushu kwiimeko ezincinci.
Apha kwi-ZHHIMG®, senza zonke ezi zinto zintathu—i-granite echanekileyo, i-ceramic echanekileyo, kunye ne-mineral casting components—kuba asikholelwa kwisisombululo esifanela zonke izinto ngobukhulu obunye. I-granite yethu emnyama ye-ZHHIMG®, enobunzima bayo obuyi-3100 kg/m³ kunye neempawu zayo zomzimba eziphezulu, ihlala iluphawu lokusetyenziswa apho uzinzo olupheleleyo lungenakuxoxiswana. Kodwa sikwaqonda ukuba i-mineral casting kunye ne-ceramics zinendawo yazo kwinkqubo yendalo echanekileyo. Isitshixo kukwazi ukuba zeziphi izinto ezisombulula ingxaki yakho ethile.
