Amathuluzi Okulinganisa I-Granite Ahlanganiswa Kanjani Ukuze Afane Ne-Sub-Micron Accuracy?

Kumathuluzi anjenge-granite eqondile, izikwele, kanye nokufana—izici eziyisisekelo zokwakha ze-metrology enobukhulu—ukuhlanganiswa kokugcina yilapho ukunemba okuqinisekisiwe kuvaliwe khona. Ngenkathi imishini yokuqala elukhuni isingathwa yimishini ye-CNC yesimanje ezindaweni zethu ze-ZHHIMG, ukufeza ukubekezelelana kwezinga le-sub-micron kanye ne-nanometer okufunwa yizindinganiso zomhlaba wonke kudinga inqubo yokuhlanganisa ngokucophelela, enezigaba eziningi kanye nokuqeda, eqhutshwa kakhulu ubuchwepheshe babantu kanye nokulawulwa okuqinile kwemvelo. Inqubo iqala ngokukhethwa kwe-ZHHIMG Black Granite yethu—ekhethwe ngenxa yobuningi bayo obuphezulu (≈ 3100 kg/m³) kanye nokuqina kokushisa—kulandelwa ukuguga kwemvelo okunciphisa ukucindezeleka. Uma ingxenye isifakwe ngomshini ibe yisimo esiseduze ne-net, ingena endaweni yethu yokuhlanganisa ezinikele, elawulwa amazinga okushisa. Yilapho umlingo wokushaya ngesandla kwenzeka khona, owenziwa yizingcweti zethu ezingochwepheshe, eziningi zazo ezineminyaka engaphezu kwengu-30 yesipiliyoni. Laba ochwepheshe abanekhono basebenzisa amasu okuklwebha nokuhlikihla ngokunemba, avame ukubizwa ngokuthi “izinga lomoya we-elekthronikhi elihambayo” ngekhono labo lokuzwa ukuphambuka okuncane, ukuze basuse kancane kancane izinto kuze kube yilapho kufinyelelwa ukuthamba okudingekayo, baqinisekise ukuthi indawo eyinhloko yokubhekisela ihambisana ngqo nezindinganiso ezifana ne-DIN 876 noma i-ASME. Okubaluleke kakhulu, isigaba sokuhlangana sihilela nokuhlanganiswa okungenakucindezeleka kwanoma yiziphi izici ezingezona i-granite, njengezithako zensimbi ezinezintambo noma izikhala ezenziwe ngokwezifiso. Lezi zingxenye zensimbi zivame ukuhlanganiswa ku-granite kusetshenziswa i-epoxy ekhethekile, ephansi, esetshenziswa ngaphansi kokulawulwa okuqinile ukuvimbela ukwethula ukucindezeleka kwangaphakathi okungalimaza ukunemba kwejometri okunzima. Ngemva kokwelashwa kwe-epoxy, indawo ivame ukunikezwa i-lapping pass yokugcina, elula ukuqinisekisa ukuthi ukungeniswa kwento yensimbi akuzange kubangele noma yikuphi ukuphambuka kweminithi ku-granite ezungezile. Ukwamukelwa kokugcina kwethuluzi elihlanganisiwe kuncike ku-loop yokulinganisa enembile. Kusetshenziswa izinsimbi ze-metrology ezithuthukisiwe njengezinga le-elekthronikhi nama-autocollimators, ithuluzi le-granite eliqediwe lihlolwa ngokuphindaphindiwe ngokumelene nezinsimbi ze-master ezilinganisiwe endaweni ezinzile ngokushisa. Le nqubo enzima—elandela isimiso sethu esiqondisayo sokuthi “Ibhizinisi lokunemba alikwazi ukuba nzima kakhulu”—iqinisekisa ukuthi ithuluzi lokulinganisa i-granite elihlanganisiwe aligcini nje ngokuhlangabezana kodwa livame ukwedlula ukubekezelelana okubekiwe ngaphambi kokuba liqinisekiswe futhi lipakishwe ukuze lithunyelwe. Le nhlanganisela yobuchwepheshe obusezingeni eliphezulu kanye nekhono elingenakuqhathaniswa elenziwe ngesandla yilokho okuchaza ukuthembeka kwesikhathi eside kwamathuluzi okunemba e-ZHHIMG.
