Amapuleti obuso be-granite angamathuluzi abalulekile ekulinganisweni nasekukhiqizeni ngokunemba, kodwa akuwona wonke amapuleti adalwe alingana. Amapuleti obuso be-granite ebanga A nebanga B ahluka kakhulu ngokunemba, ukuqeda ubuso, izimo zokusetshenziswa, kanye nezindleko. Ukuqonda lokhu kuhlukanisa kusiza izimboni ukuthi zikhethe inketho efanele kakhulu izidingo zazo ezithile.
Ukubekezelelana Okuyisicaba: Umongo Wokunemba
Ukubekezelelana kokuthamba kuyisici esiyinhloko sokuhlukanisa phakathi kwala mabanga amabili. Ngokusho kwe-American Society of Mechanical Engineers (ASME) B89.3.7 ejwayelekile, amapuleti eBanga A anikeza ukunemba okuphezulu. Isibonelo, epuletini elingu-12” x 12”, iBanga A livame ukuba nokubekezelelana kokuthamba okungu-±0.00008 amasentimitha, okuqinisekisa indawo eyisicaba ecishe ibe ephelele. Ngokuphambene nalokho, amapuleti eBanga B anokubekezelelana okukhululekile, cishe ama-±0.00012 amasentimitha ngobukhulu obufanayo. Lo mehluko wenza iBanga A libe lihle kakhulu ezinhlelweni zokusebenza ezidinga ukunemba okukhulu, njengokulinganisa izinsimbi zokulinganisa eziphezulu, kuyilapho iBanga B lanele imisebenzi yokuhlola ejwayelekile ezindaweni zokusebenzela.
Ubulukhuni Bomphezulu: Umthelela Ekulinganisweni
Ubulukhuni bomphezulu buyahlukahluka phakathi kwamabanga. Amapuleti eBanga A adlula ezinqubweni ezibanzi zokugoqa nokupholisha, okuholela endaweni ebushelelezi enesilinganiso sobulukhuni (Ra) esivame ukuba ngaphansi kwamasentimitha angu-0.0005. Lokhu kuqeda okubushelelezi kakhulu kunciphisa ukungqubuzana futhi kuvimbele ukuklwebheka ezingxenyeni ezibucayi ngesikhathi sokulinganisa. Amapuleti eBanga B, anenani likaRa elingaba amasentimitha angu-0.001, aqinile kakhulu. Nakuba esengenza imisebenzi yokulinganisa eyisisekelo, angase angafaneleki ukuphatha izingxenye ezibucayi.
Izimo Zokusebenza: Ukuqondanisa Nezidingo
Ukukhetha phakathi kweBanga A neBanga B kuncike kakhulu ekusetshenzisweni. Ekukhiqizweni kwezindiza kanye ne-semiconductor, lapho ukunemba kwezinga le-micrometer kubalulekile khona, amapuleti eBanga A ayathandwa. Isibonelo, lapho kulinganiswa ukuthamba kwe-turbine blade noma ukuhambisana kwama-microchip, ngisho nokuphambuka okuncane kakhulu kungathinta ukusebenza komkhiqizo. Amapuleti eBanga B, nokho, avame ukusetshenziswa ekukhiqizweni kwezimoto, ekusetshenzisweni kwemishini ejwayelekile, nasezikhungweni zemfundo. Anele ukuhlola ubukhulu bamabhulokhi enjini noma ukufundisa izimiso zokulinganisa eziyisisekelo ngaphandle kwesidingo sokunemba okuphezulu kakhulu.
Inqubo Yokukhiqiza Nezindleko: Ukushintshana Okufanele Kucatshangelwe
Amapuleti eBanga A adinga inqubo yokukhiqiza ecophelelayo. Abadwebi bachitha isikhathi esiningi ekukhetheni izinto, ukusika ngokunembile, kanye nokupholisha iziteji eziningi ukuze kufezwe ukuthamba okufiselekayo kanye nokuqeda ubuso. Leli zinga eliphakeme lobuciko, kanye nesidingo sokulawula ikhwalithi eqinile, kukhulisa izindleko zokukhiqiza. Ngenxa yalokho, amapuleti eBanga A ngokuvamile abiza kakhulu ngo-30 - 50% kunalawo eBanga B. Ezimbonini noma izinhlelo zokusebenza ezisebenzisa isabelomali esincane ezinezidingo zokunemba ezingabizi kakhulu, amapuleti eBanga B anikeza enye indlela engabizi kakhulu.
Ngamafuphi, amapuleti obuso begranite eBanga A neBanga B ahlangabezana namazinga ahlukene okunemba nezidingo zokusetshenziswa. Ngenkathi iBanga A lihamba phambili ezindaweni eziqhutshwa ukunemba okuphezulu, iBanga B linikeza ukusebenza okuthembekile ngentengo ephansi yokusetshenziswa okuvamile. Ngokuhlola ngokucophelela lo mehluko, abakhiqizi nabasebenzisi bangenza izinqumo ezinolwazi ezithuthukisa kokubili ukunemba nokusebenza kahle kwezindleko.
