Nasi umbuzo engithanda ukuwubuza abaphathi bezitolo ezinembile: kunini lapho ugcine khona ukuthemba ipuleti lakho elingaphezulu?
Hhayi ukuthi “ibukeka icwebezela.” Hhayi ukuthi “idlule ekuhlolweni okuzayo.” Ngisho ukuthi ithembekile — uhlobo lokuthembana lapho ubeka khona ingxenye esanda kufakwa kuyo, usebenzise izilinganiso zakho, futhi wazi ukuthi izinombolo ozifundayo zimayelana nengxenye, hhayi ipuleti elihamba ngaphansi kwayo.
Iningi labantu liyanqikaza. Abanye bayashintsha indaba. Abambalwa bayavuma ukuthi abanalo ulwazi, ngoba abakaze bahlole.
Yilapho-ke iqala khona yonke le ngxoxo.
Kungani Amapuleti Okungaphezulu Asabalulekile Ngaphezu Kokucabanga Kwabathengi Abaningi
Siphila enkathini yama-laser interferometers, izinhlelo zokubona, kanye nama-touch probe angalinganisa izici ezincane ngemizuzwana. Kulula ukuphatha ipuleti elingaphezulu njengensalela - idwala eliyisicaba elisindayo (noma ucezu olusindayo lwensimbi ephonswe) elihlezi ekhoneni legumbi lokuhlola elingenzi lutho.
Ngaphandle kokuthi yenza cishe konke.
Ipuleti lobuso liyindilinga yokubhekisela lapho kwenziwa khona izilinganiso eziningi ezenziwe ngesandla kanye nezengxenye yesandla. Ukufundwa ngakunye kwe-micrometer okuthathayo ngesilinganiso sokuphakama, konke ukusethwa kwesibonakaliso sokuhlola, konke ukuqhathanisa phakathi kwento yokusebenza eyenziwe ngomshini kanye nendinganiso yokubhekisela — konke kugeleza endaweni ingxenye ehleli kuyo. Uma leyo ndawo ingazinzile ngokwejiyometri futhi ingabikezelwa ngokushisa, konke ukulinganisa okungezansi komfula kunephutha elingalinganiswanga.
Iqiniso elingathandeki ukuthi izitolo eziningi zisebenzisa ukulawulwa kwekhwalithi ezisekelweni ezingakabuzi eminyakeni eminingi. Ngezinye izikhathi amashumi eminyaka.
Insimbi Ephonsweyo vs. I-Granite: Ukuqhathanisa Kwangempela Akekho Okwenza Kahle
Ngena ezindaweni zokukhiqiza eziyishumi ngokunemba uzothola ukuhlukaniswa okucishe kube ngu-50/50 phakathi kwamapuleti omhlaba ensimbi ecijile kanye ne-granite. Buza abathengi ukuthi kungani bakhethe lokho abakukhethile, futhi iningi labo lizokunikeza impendulo ezwakala inengqondo kodwa engabambeleli ekuhlolweni.
"Ngikhethe insimbi ephothiwe ngoba iyinto yendabuko."
"Ngikhethe i-granite ngoba izinzile kakhulu."
Zombili lezo zimpendulo aziphelele. Nakhu ukuthi uhlaka lwesinqumo sangempela lubukeka kanjani:
Amapuleti obuso bensimbi ephonsweKube yindinganiso yezimboni iminyaka engaphezu kwekhulu, futhi ngezizathu ezinhle. Zinezici ezinhle kakhulu zokudambisa — zimunca ukudlidliza kangcono kune-granite, okubalulekile ezindaweni zomshini osindayo. Kulula futhi ukuziphinda zivele uma zigugile. Umenzi wemishini onekhono angakhuhla ipuleti lobuso lensimbi eligugile alibuyisele esimweni salo ngokushesha, okwenza ukulungiswa kube lula.
Ukushintshana kuba ukuzwela kokushisa. Insimbi ephothiwe iyakhula futhi inciphe ngokuphawulekayo ngokushintsha kwezinga lokushisa. Ipuleti lensimbi ephothiwe esitolo esingashisi ebusika liziphatha ngendlela ehlukile ngokwejiyometri kunepuleti elifanayo ehlobo. Ngomsebenzi odinga ukunemba kwezinga le-micron kuzo zonke izilinganiso ezinkulu, lokhu kujikeleza kokushisa akuyona into encane.
Amapuleti obuso begraniteXazulula inkinga yokushisa kahle. I-granite emnyama ine-coefficient yokwandisa ukushisa ephansi kakhulu kanye nokuqina okumangalisayo phakathi kwamazinga okushisa okusebenza ajwayelekile. Ipuleti le-granite alidingi ukulawulwa kwesimo sezulu ukuze libambe i-geometry yalo ngendlela insimbi ephonswe ngayo. Futhi ayiboli, ayigqwali, futhi ayidingi ukugcotshwa ngamafutha.
Ukushintshana kuwukuthi kulula ukulungisa. Uma indawo ye-granite iguga noma yonakala, awukwazi ukuyikhuhla ngendlela ongayenza ngayo ngensimbi ephonswe ngensimbi. Ubheka ukuphinde uyixhume (okubizayo nokudla isikhathi) noma ukuyishintsha. Yingakho ikhwalithi yezinto zokwakha zokuqala kanye nokunemba kokukhiqiza kubaluleke kakhulu nge-granite - wenza ukuzibophezela kwesikhathi eside lapho uthenga.
Okubalulekile ngempela ensimini: ngezicelo eziningi zokuhlola ezindaweni ezilawulwayo, ukuzinza kokushisa kwe-granite kuyinika umkhawulo olinganisekayo. Ngomshini osindayo kanye nokuhlanganiswa okukhulu lapho ukudambisa nokudlidliza kubalulekile khona, insimbi ephonsweyo isathola indawo yayo.
Kuchazwa Uhlelo Lwebanga: Lokho Okukuthengayo Empeleni
Iningi lezindinganiso zepuleti lobuso libhekisela ezindinganisweni ezifana ne-DIN 876, i-ASME GGGP-463C, noma i-ISO 8512. Lezi zindinganiso zichaza amazinga okunemba — ngokuvamile iBanga 00, iBanga 0, iBanga 1, kanye neBanga 2 — ngokusekelwe ekubekezeleni ukuthamba.
Nakhu okushiwo yilawo mabanga ekusebenzeni, kusetshenziswa indinganiso ye-DIN 876 njengereferensi:
Ibanga 00 livumela cishe ama-micron angu-2.3 okuphambuka kokusicaba ngaphezu kuka-1,000mm. Ibanga 0 livumela cishe ama-micron angu-4.6. Ibanga 1 livumela cishe ama-micron angu-9.2. Ibanga 2 livumela cishe ama-micron angu-18.5.
Leyo ndlela yokuphindaphinda kabili ayiyona into engavamile — isinyathelo ngasinye sokwehla ebangeni simelela ukuphindaphinda kabili kwephutha elivumelekile. Futhi leso sabelomali sephutha akufanele simboze nje ukubekezelela ukukhiqiza, kodwa nokuwohloka kwepuleti ngesikhathi sokusebenza kwayo.
Ngomongo: uma ulinganisa izingxenye ezifakwe kumshini zibe ama-±2 microns, ipuleti lobuso leBanga 1 (ama-microns angu-9.2 okuphambuka okuvumelekile kokuthamba) selivele lidla cishe u-20% webhendi yakho yokubekezelelana iyonke — ngaphambi kokuthi ucabangele noma yimuphi omunye umthombo wokungaqiniseki kokulinganisa. Leyo inombolo okufanele ihlale nayo.
Yingakho amalebhu e-metrology aqinile kanye nezinhlelo zekhwalithi yezindiza cishe zichaza iBanga 00. Izindleko ezengeziwe zepuleti lezinga eliphezulu zincane uma ziqhathaniswa nezindleko zephutha lokulinganisa elingatholakali eliwela eqenjini lezingxenye ezingahambisani.
Yini Ebulale Ipuleti Lakho Lokugcina Lomphezulu (Nokuthi Yini Emihle Eyivimbelayo)
Amapuleti angaphezulu awaphumeleli kakhulu. Ayakhukhuleka. Amunca umswakama. Aqoqa umonakalo ongaphansi komhlaba ovela ezithwalini zomsebenzi eziwile. Akha amaphethini okuguguleka asendaweni ngokuxhumana okuphindaphindiwe namaphuzu okulinganisa afanayo.
Imodi yokuhluleka evame kakhulu yamapuleti ensimbi enziwe ngobumba ezindaweni ezinomswakama ukushintsha kobukhulu obubangelwa umswakama. Ngisho noma kufakwe uwoyela ngendlela efanele, insimbi enziwe ngobumba inezimbobo ezanele ukumunca umhwamuko wamanzi ngokuhamba kwesikhathi, ikakhulukazi ezindaweni ezingenalo ukulawulwa kwesimo sezulu. Umphumela uba ukulahlekelwa kancane kancane kokusicaba okungaveli esitifiketini sokulinganisa kodwa okubonakala njalo uma uzama ukubamba ukubekezelelana okuqinile.
Amapuleti e-granite ahluleka ngendlela ehlukile. Inkinga evame kakhulu akuyona inkinga yekhwalithi ye-granite — kuyinkinga yokushaqeka kokushisa.
