Ubuchule bokuLapsa ngesandla kunye neMetrology yeLaser: Ukufezekisa ukuLula kweNanometer kwiMveliso yoBuninzi

Oomatshini bokugrumba bekhompyutha banamhlanje (CNC) bayamangalisa ngokwenziwa kwezinto ngokuzenzekelayo kwimizi-mveliso. Izixhobo zokugaya ezinkulu, ezifana nee-grinders eziphezulu ezingama-6000 mm, zinokucubungula ngokukhawuleza amaqonga esinyithi kunye nee-non-metal ukuze zikwazi ukumelana kakuhle. Nangona kunjalo, xa iinkcukacha zifuna ukuba i-nanometer ibe tyaba kwiindawo ezinkulu, i-mechanical machining ifikelela kwimida yayo ebonakalayo.

Ukulungiswa okugqibeleleyo kwezinto zegranite ezichanekileyo, iipleyiti zomphezulu, kunye nemiphetho ethe tye kufuna indibaniselwano yempendulo yeemvakalelo zomntu kunye ne-laser interferometry.

Imida Yokugaya Oomatshini

Nokuba zezona ziphambiliOomatshini bokugaya be-CNCzineziphene ezingokwemvelo zoomatshini. Ukuchitheka kwespindle, ukuphambuka kwesakhiwo segantry yomatshini, kunye notshintsho lobushushu oluncinci kwi-coolant kubangela iipatheni zamaza ajikelezayo kwindawo yokusebenza esemhlabeni. Ezi mpawu zoomatshini zithintela oomatshini abaqhelekileyo ukuba bangagqobhozi umqobo we-sub-micron kwizinto ezinkulu.

 

Ukuze kufezekiswe iprofayili ye-nanometer yokwenyani, eli candelo kufuneka lilungiswe ngesandla ngokukodwa, inkqubo eyaziwa ngokuba yi-hand-lapping.

Inkqubo Yokutsalela Isandla: Impendulo Yokuthinta Emalengeni Amancinci

Ukulepha ngesandla bubugcisa obukhethekileyo boomatshini apho iingcali ezingoochwephesha zisebenzisa iikhompawundi ezirhabaxa kunye neebhloko zokulepha ezenziwe ngokwezifiso ukususa izinto kwiindawo eziphakamileyo kwiindawo eziphakamileyo.umphezulu wegranite.

• Ukuchaneka kwe-Tactile Sensorial: Iingcali zeengcali zine-tactile sensitivity eziphuhliswe kwiminyaka emininzi yamava ezandla. Ziyakwazi ukubona umahluko kumphezulu ukuya kuthi ga kwi-micrometers ezinenombolo enye ngokuziva ukumelana nokungqubana kwe-lapping block.

• Ukulungiswa Okuphindaphindayo: Le nkqubo iphindaphindwayo kuphela. Ingcali ijika umphezulu, ivumela izinto ukuba zizinze ngokobushushu, ilinganise i-topography ngezixhobo ze-elektroniki ze-metrology, kwaye iphinda le nkqubo ide ifikelele kwi-flatness ekujoliswe kuyo.

• Ubukhulu beNanometer: Ngale ndlela yesandla, amabala aphezulu ancitshiswa ngokuthe ngcembe, okuvumela iipleyiti ezinkulu zomphezulu wegranite ukuba zifikelele kwiiprofayili zomphezulu ukuya kuthi ga kwimida yenanometer—ezingenakufezekiswa ngamavili okugaya azenzekelayo kuphela.

Ukuqinisekisa Ukuchaneka nge-Advanced Metrology kunye ne-Traceability

Izakhono zokwenza ngesandla aziphumeleli ngaphandle kokuqinisekiswa ngokupheleleyo kokulinganisa. Ukuqinisekisa iindawo ezijikeleziweyo ngesandla, izixhobo zemveliso zisebenzisa izixhobo zemetrology eziphambili ezilinganiswe ngokwemigangatho yamazwe ngamazwe.

• I-Laser Interferometry: Iinkqubo ezifana ne-Renishaw laser Interferometer zisetyenziselwa ukuzoba iimpazamo ezithe tyaba, ezijijekileyo, nezithe tyaba zeendlela ezikhokelayo kunye nemiqadi yesakhiwo kumgama omde (ukuya kuthi ga kwi-20 m).

• Ukulinganisa i-Electronic Leveling: Amanqanaba e-elektroniki e-Swiss WYLER asetyenziswa kwii-differential pairs ukuze abambe i-angular pitch kunye ne-roll deviations ukuya kwi-0.5μm.

• Ukuhlolwa kweMicro-Topography: Izibonisi zedayari yeMahr (isisombululo se-0.5μm), ii-calipers zedijithali zeMitutoyo, kunye nabavavanyi bokurhabaxa komphezulu abachanekileyo baqinisekisa ukuba ubume begranite buyahambelana neenkcukacha zegumbi lokucoca.

Ukubaluleka Kokulandelelana Kokulinganisa Kwesizwe

Umlinganiselo usebenza kuphela ukuba unokuqinisekiswa ngumntu wesithathu ozimeleyo. Zonke izixhobo zemetrology eziphezulu kufuneka zibe nezatifikethi zokulinganisa ezisemthethweni ezikhutshwe zizikhungo zengingqi ezivunyiweyo, ezifana neShandong Institute of Metrology okanye iJinan Institute of Metrology.

Okubalulekileyo kukuba, yonke imigangatho yesalathiso esetyenziswa kumzi-mveliso kufuneka ibe nothotho olungaqhekekiyo lokulandelela olubuyela kwiNational Institute of Metrology (NIM). Oku kuqinisekisa ukuba xa injineli yokuthenga evela kwi-Apple, Samsung, okanye iBosch iphonononga ingxelo yokuhlolwa kwecandelo le-granite le-ZHHIMG®, idatha iyasebenza phantsi kwezivumelwano ze-metrology zamazwe ngamazwe.
