Ekulinganisweni okunembile, ukunemba kwamathuluzi akho kuncike kakhulu kwikhwalithi yendawo yokubhekisela engaphansi kwawo. Phakathi kwazo zonke izisekelo zokubhekisela okunembile, amapuleti obuso be-granite aziwa kabanzi ngokuqina kwawo okumangalisayo, ukuqina, kanye nokumelana nokuguguleka. Kodwa yini echaza izinga lawo lokunemba - futhi kusho ukuthini ngempela ukubekezelela ukuthamba “kwebanga elingu-00”?
Kuyini Ukuthamba Kwebanga Elingu-00?
Amapuleti obuso begranite akhiqizwa ngokwezindinganiso eziqinile ze-metrology, lapho ibanga ngalinye limelela izinga elihlukile lokunemba kokusicaba. Ibanga le-00, elivame ukubizwa ngokuthi ibanga lelabhorethri noma ibanga lokucacisa kakhulu, linikeza izinga eliphakeme kakhulu lokunemba elitholakalayo kumapuleti egranite ajwayelekile.
Kupuleti lobuso le-granite elingama-00-grade, ukubekezelelana kokusicaba ngokuvamile kungaphakathi kuka-0.005mm ngemitha. Lokhu kusho ukuthi ngaphezu kwanoma yibuphi ubude bobuso obuyimitha elilodwa, ukuphambuka ekusicaba okuphelele ngeke kudlule ama-micron amahlanu. Ukunemba okunjalo kuqinisekisa ukuthi amaphutha okulinganisa abangelwa ukungalungi kobuso aqedwa cishe — into ebalulekile ekulinganisweni okuphezulu, ukuhlolwa kokubona, kanye nokusetshenziswa kokulinganisa okuhlelekile.
Kungani Ukuthamba Kubalulekile
Ukuthamba kunquma ukuthi ipuleti elingaphezulu lingasebenza ngokunembile kangakanani njengereferensi yokuhlola nokuhlanganisa ubukhulu. Ngisho nokuphambuka okuncane kungaholela emaphutheni amakhulu okulinganisa lapho kuhlolwa izingxenye ezinembile. Ngakho-ke, ukugcina izindawo eziphansi kakhulu kubalulekile ukuqinisekisa imiphumela ehambisanayo emalabhorethri, ezindaweni zezindiza, nasezindaweni zokukhiqiza lapho kudingeka khona ukunemba kwezinga le-micrometer.
Ukuzinza Kwezinto Nokulawulwa Kwemvelo
Ukuqina okumangalisayo kwamapuleti e-granite angama-00-grade kuvela ekukhuleni okuphansi kokushisa kwe-granite yemvelo kanye nokuqina okuhle kakhulu. Ngokungafani namapuleti ensimbi, i-granite ayigobeki ngaphansi kokushintsha kwezinga lokushisa noma ithonya likamagnetic. Ipuleti ngalinye lihlanganiswa ngokucophelela futhi lihlolwe endaweni elawulwa izinga lokushisa (20 ± 1°C) ukuqinisekisa ukuthi ukuthamba kuhlala kufana ngaphansi kwezimo zokusebenza.
Ukuhlolwa Nokulinganiswa
Kwa-ZHHIMG®, yonke ipuleti le-granite elingaphezulu kwebanga le-00 liqinisekiswa kusetshenziswa amazinga e-elekthronikhi anembile kakhulu, ama-autocollimator, kanye nama-interferometer e-laser. Lawa mathuluzi aqinisekisa ukuthi ipuleti ngalinye lihlangabezana noma lidlula amazinga omhlaba wonke njenge-DIN 876, GB/T 20428, kanye ne-ISO 8512. Ukulinganisa nokuhlanza njalo nakho kubalulekile ukuze kulondolozwe ukunemba kokuthamba kwesikhathi eside.
Ukunemba Ongakwethemba
Uma ukhetha ipuleti lobuso le-granite lesistimu yakho yokulinganisa, ukukhetha ibanga elifanele kuthinta ngqo ukuthembeka kwakho kokulinganisa. Ipuleti lobuso le-granite elingama-00-grade limelela isiqongo sokunemba kobukhulu — isisekelo okwakhelwe kuso ukunemba kwangempela.
