Ipuleti lobuso begranite liwutshalomali lwesikhathi eside, incazelo yempahla eqinile emhlabeni we-metrology. Noma kunjalo, leli thuluzi elibalulekile aligodli ekugugeni, ekulimaleni, noma ekulahlekelweni okungenakugwenywa kokusicaba ngokuhamba kwesikhathi. Kunoma yimuphi umphathi wokulawula ikhwalithi, ukuqonda hhayi nje kuphela ukukhethwa okufanele kwepuleti lobuso lokuhlola igranite kodwa nezinqubo zokulungisa ipuleti lobuso begranite kubaluleke kakhulu ekunciphiseni isikhathi sokungasebenzi kanye nokugcina ukunemba. Ukulindela ukuthi ipuleti lobuso, kungakhathaliseki ukuthi lipuleti lobuso begranite elinobukhulu obuncane noma olunye uhlobo oluhamba phambili, lizogcina ukusicaba kwalo okuqinisekisiwe unomphela akulona iqiniso.
I-Anatomy Yokuguguleka: Kungani Ukulungiswa Kwepuleti Lomphezulu We-Granite Kudingeka
Isizathu esiyinhloko sokuthi ipuleti le-granite lidinga ukunakekelwa ukuguguleka kwendawo. Ngisho ne-granite emnyama enzima kakhulu inqotshwa ukungqubuzana okuqhubekayo okuvela kumathuluzi okulinganisa, izinto zokusebenza, kanye nezinhlayiya zothuli ezirhabaxa. Lokhu kuguguleka kuvame ukubonakala ezindaweni eziguguleka kakhulu, ezenzeka lapho izinsimbi ezifana nama-geage okuphakama zivame ukusethwa futhi zihanjiswe, okudala ukucwila okuncane okuphazamisa ukufundwa kokuphindaphinda kwendawo. Lokhu kuvame ukuba uphawu lokuqala lokuthi ukulungiswa kwepuleti lobuso be-granite lochwepheshe kungadingeka. Ngaphezu kwalokho, umthelela ongalindelekile emaphethelweni noma emakhoneni epuleti kungabangela ukuqhekeka; kuyilapho ama-chips kude nendawo yokusebenza engase angathinti ngqo ukuguguleka, angafaka engcupheni ubuqotho besakhiwo futhi abonise ukuphathwa kabi. Ngaphezu kwalokho, eminyakeni eminingi yokusetshenziswa kakhulu, lonke ipuleti lingawa kancane kancane ebangeni lalo eliqinisekisiwe (isb., ipuleti le-Grade 0 lingase liwohloke libe yi-Grade 1 tolerance). Lokhu kudinga ukuphinda kufakwe umphezulu ngokuphelele. Lapho ukubekezelelana okudingekayo komsebenzi wokuhlola kungasahlangatshezwana, ikhambi aliyona inqubo yokulungisa ekhethekile ebizwa ngokuthi ukuphinda kufakwe umphezulu noma ukuphinda kufakwe umphezulu. Lokhu kuhilela ochwepheshe abanekhono eliphezulu abaguguleka ngokucophelela izindawo eziphakeme epuletini besebenzisa ama-compounds abrasive kanye namapuleti amakhulu okubhekisela, okubuyisela ukuguguleka ngaphakathi kokubekezelelana okuqinisekisiwe. Le nsizakalo ekhethekile yandisa isikhathi sokuphila kwepuleti ngokungenamkhawulo, okwenza kube yisici esibalulekile sokuphathwa kwemishini ye-metrology.
Izinga Legolide: Iyini Izinga Lepuleti Lomphezulu Wegranite?
Ukuze uphathe kahle ilabhorethri ye-metrology, umuntu kumele aqale achaze ukuthi yini ejwayelekile yokunemba kwepuleti le-granite surface. Le nqubo ibhekisela kumazinga okubekezelelana aqashelwa emhlabeni wonke (AA, 0, kanye no-1) asungulwe yizincazelo ezifana ne-US Federal Specification GGG-P-463c noma i-German DIN 876. Le mibhalo inquma ukuphambuka okuphezulu okuvunyelwe kusuka endaweni ephelele, okuqinisekisa ukushintshana kwezingxenye kanye nokulinganisa emhlabeni jikelele. Nokho, indinganiso yangempela ihlanganisa nefilosofi yokuthola okuthembekile. Abakhiqizi abafana nepuleti le-granite surface eliyi-insize noma ezinye izinhlobo ezisunguliwe banamathela ezimisweni zokulawula ikhwalithi eziqinile, hhayi nje ekufinyeleleni ukuthamba kokuqala kodwa nasekuqinisekiseni ikhwalithi ye-granite emnyama eluhlaza - ukuqinisekisa ukuthi inokuqukethwe kwe-quartz ephansi, ukuminyana okuphezulu, kanye ne-coefficient ephansi yokwanda kokushisa (CTE) ukumelana nokushintsha kobukhulu ngenxa yokushintshashintsha kwezinga lokushisa. Ipuleti lokuhlola i-granite elithengwe kumhlinzeki othembekile liqinisekisa ukuthi izinto ngokwazo zifanelekile emsebenzini onembile kakhulu.
Ukuhlomisa Ukuhlolwa: Indima Yepuleti Lomphezulu Wegranite Nge-Indicator Post
Umsebenzi oyinhloko owenziwa epuletini lokuhlola i-granite surface gauging ukuqhathanisa, lapho kusetshenziswa khona indinganiso eyaziwayo (i-gage block) ukusetha i-gauge, bese umsebenzi ulinganiswa ngalolo bukhulu obubekiwe. Le nqubo ivame ukusebenzisa ipuleti lobuso be-granite eline-index poll. I-index poll, ngokuvamile ikholomu eqinile efakwe kwisisekelo se-magnetic noma se-mechanical, ibamba i-dial test indicator noma i-digital probe. Ukuqina kwayo kubalulekile ekulinganisweni okunembile. Ngenkathi ama-column gauge alula angahanjiswa azungeze ipuleti, ukuba nepuleti elenziwe ngokukhethekile ukuhlanganisa lezi zinto kusiza inqubo yokuhlola ibe lula. Ipuleti lobuso be-granite eline-index poll ngokuvamile lisho ukusethwa okuhlala njalo, okuzinzile kakhulu, ngezinye izikhathi kusetshenziswa i-threaded inserts ngaphakathi kwepuleti ukuze kuboshwe i-poll ngqo, kususwe ukunyakaza okuncane noma ukuthambekela okungenzeka ngezisekelo ze-magnetic. Ngaphezu kwalokho, i-granite inikeza i-datum efanelekile yokusetha iphuzu le-index zero usebenzisa i-gage block, futhi i-index poll igcina ukuphakama nokuma, iqinisekisa ukulinganisa okuphindaphindwayo kakhulu, okuyisisekelo se-metrology yokuhlola. Lokhu kuhlanganiswa kwensika ezinzile nepuleti lokuhlola eliqinisekisiwe le-granite surface kukhulisa ukunemba okungenzeka kwesistimu yokulinganisa yonke, kuguqula i-slab elula ibe yisiteshi sokulinganisa esiphelele nesinembile kakhulu.
Ukugcina Ubuqotho Bepuleti Lokuhlola I-Granite Surface
Ukunakekelwa kokuvimbela kushibhile njalo kunokulungiswa kwepuleti le-granite surface. Nakuba ukuguguleka kungenakugwenywa, izinga lalo lingancishiswa kakhulu ngokuhlanza indlu ngendlela ehlelekile. Isitha esikhulu sepuleti uthuli kanye nokungcola, okusebenza njengodaka oluhlabayo ngaphansi kwezinsimbi. Abasebenzisi kufanele bahlanze ipuleti ngokucophelela ngaphambi nangemva kokusetshenziswa ngakunye ngesihlanzi sepuleti le-surface esikhethekile, futhi bangalokothi bahudule izinto ezisindayo phezu kobuso. Ekugcineni, ukuzibophezela kwikhwalithi ye-metrology kusho ukwamukela umjikelezo wokuphila odingekayo walezi zinsimbi: ukukhetha ngokucophelela, ukusetshenziswa, ukulinganiswa okuhleliwe, kanye nokulungiswa kwepuleti le-granite surface okudingekayo. Ngokunamathela eqinisweni lokuthi ukunamathela ngokuqinile ezindinganisweni zobukhulu kuyindinganiso yepuleti le-granite surface, ochwepheshe bokulawula ikhwalithi bavikela ukunemba kwesilinganiso ngasinye esifaka isandla ekuthembekeni kokugcina komkhiqizo.
