Ubuchwepheshe Bokugoqa Ngesandla kanye Nokulinganisa Nge-Laser: Ukufeza Ukuthamba Kwe-Nanometer Ekukhiqizeni Okukhulu

Imishini yokugaya yesimanje yokulawula izinombolo zekhompyutha (CNC) iyisimangaliso sokwenza izinto ngokuzenzakalela kwezimboni. Imishini yokugaya emikhulu, njengemishini yokugaya ephezulu engu-6000 mm, ingacubungula ngokushesha amapulatifomu ensimbi kanye nengewona awensimbi ukuze ikwazi ukumelana kahle. Kodwa-ke, lapho imininingwane idinga ukuba yisicaba ezingeni le-nanometer phezu kwezikhala ezinkulu, imishini yokugaya yemishini ifinyelela imikhawulo yayo ebonakalayo.

Ukulungiswa okuphelele kwezingxenye ze-granite ezinembile, amapuleti angaphezulu, kanye nemiphetho eqondile kudinga inhlanganisela yempendulo yezinzwa zomuntu kanye ne-laser interferometry.

Imikhawulo Yokugaya Okwenziwa Ngomshini

Ngisho nethuthuke kakhuluImishini yokugaya ye-CNCzinamaphutha emishini angokwemvelo. Ukugeleza kwe-spindle, ukuphambuka kwesakhiwo se-gantry yomshini, kanye nokushintshashintsha kokushisa okuncane kakhulu ku-coolant kubangela amaphethini wamagagasi ajikelezayo endaweni yokusebenza ephansi. Lezi zimpawu zemishini zivimbela imishini ejwayelekile ukuthi ingaphuli umgoqo we-sub-micron ezingxenyeni ezinkulu.

 

Ukuze kufezwe iphrofayili ye-nanometer yangempela, ingxenye kumele ilungiswe ngesandla ngokukhethekile, inqubo eyaziwa ngokuthi i-hand-lapping.

Inqubo Yokugoqa Ngesandla: Impendulo Yokuthinta Esezingeni Elincane

Ukugoqa ngesandla kuwubuciko obukhethekile bemishini lapho ochwepheshe abangochwepheshe basebenzisa khona izinto ezihudulayo kanye namabhulokhi okugoqa ngokwezifiso ukuze basuse izinto ezindaweni eziphakeme.ubuso begranite.

• Ukunemba Kwezinzwa Zokuthinta: Ochwepheshe abangochwepheshe banokuzwela kokuthinta okuthuthukisiwe eminyakeni eminingi yokuhlangenwe nakho ngesandla. Bangakwazi ukubona ukushintshashintsha kobuso kuze kufike kuma-micrometer ezinombolo eyodwa ngokuzwa ukumelana nokungqubuzana kwe-lapping block.

• Ukulungiswa Okuphindaphindayo: Le nqubo iphindaphindwayo kuphela. Uchwepheshe udlula phezulu, avumele izinto ukuthi zizinze ngokushisa, alinganise i-topography ngamathuluzi e-metrology kagesi, futhi aphinde inqubo kuze kube yilapho kufinyelelwa ukuthambekela okuqondiwe.

• Ukuthamba kwe-Nanometer: Ngale ndlela yesandla, izindawo eziphakeme ziyancishiswa kancane kancane, okuvumela amapuleti aphezulu e-granite ukuthi afinyelele amaphrofayili obuso kuze kufike emikhawulweni ye-nanometer—okungafinyeleleki ngamasondo okugaya azenzakalelayo kuphela.

Ukuqinisekisa Ukunemba nge-Advanced Metrology kanye ne-Traceability

Ikhono lezandla alisebenzi ngaphandle kokuqinisekiswa okuphelele kokulinganisa. Ukuze kuqinisekiswe izindawo ezihambisana nezandla, izikhungo zokukhiqiza zisebenzisa imishini ye-metrology ethuthukisiwe elinganiswe ngokwezindinganiso zomhlaba wonke.

• I-Laser Interferometry: Izinhlelo ezifana ne-Renishaw laser Interferometer zisetshenziselwa ukudweba amaphutha aqondile, angama-angular, kanye nokuthamba kwezindlela zokuqondisa kanye nemishayo yesakhiwo emabangeni amade (kufika ku-20 m).

• Ukulinganisa Okuhlukile Kwe-elekthronikhi: Amazinga kagesi e-Swiss WYLER asetshenziswa ngama-differential pairs ukuze abambe ukuphambuka kwe-angular pitch kanye ne-roll kuze kufike ku-0.5μm.

• Ukuhlolwa Kwe-Micro-Topography: Izinkomba zokudayela ze-Mahr (ukulungiswa okungu-0.5μm), ama-caliper edijithali e-Mitutoyo, kanye nabahloli bokuhluzeka kobuso obunembile kakhulu baqinisekisa ukuthi ukuthungwa okuncane kwe-granite kufanelana nemininingwane yegumbi lokuhlanza.

Isidingo Sokulandelela Ukulinganiswa Kukazwelonke

Isilinganiso sisebenza kuphela uma singaqinisekiswa yiqembu lesithathu elizimele. Zonke izinsimbi zokulinganisa ezisezingeni eliphezulu kumele zibe nezitifiketi zokulinganisa ezisebenzayo ezikhishwe yizikhungo zesifunda ezigunyaziwe, njengeShandong Institute of Metrology noma iJinan Institute of Metrology.

Okubaluleke kakhulu, yonke indinganiso yokubhekisela esetshenziswa efektri kumele ibe nochungechunge olunganqamuki lokulandelela emuva ku-National Institute of Metrology (NIM). Lokhu kuqinisekisa ukuthi lapho unjiniyela wokuthenga ovela ku-Apple, Samsung, noma Bosch ebuyekeza umbiko wokuhlola wengxenye ye-granite ye-ZHHIMG®, idatha isebenza ngaphansi kwezivumelwano zomhlaba wonke ze-metrology.
