Eyona nto iphambili kushishino oluchanekileyo kakhulu—ukusuka kwimveliso ye-semiconductor ukuya kwi-aerospace metrology—kukho iqonga le-granite. Eli candelo, elidla ngokungajongwa njengebhloko yelitye eqinileyo, lisisiseko esibalulekileyo nesizinzileyo sokufikelela kumlinganiselo ochanekileyo kunye nolawulo lokuhamba. Kwiinjineli, iingcali ze-metrology, kunye nabakhi boomatshini, ukuqonda oko kuchaza ngokwenene “ukuchaneka” kweqonga le-granite kubaluleke kakhulu. Akupheleli nje ekugqityweni komphezulu; kumalunga neqoqo lezalathisi zejometri ezilawula ukusebenza kweqonga lokwenyani.
Ezona zibonakaliso zibalulekileyo zokuchaneka kweqonga legranite yiFlatness, Strength, kunye neParallelism, zonke ezimele ziqinisekiswe ngokwemigangatho yamazwe ngamazwe eqinileyo.
Ukuthambeka: Iplani yeNgcebiso ePhambili
Ukuthe tyaba mhlawumbi sesona sibonakaliso sibalulekileyo kuyo nayiphi na iplatifomu yegranite echanekileyo, ingakumbi iGranite Surface Plate. Ichaza indlela yonke indawo yokusebenza ehambelana ngayo neplani egqibeleleyo yethiyori. Ngokwenyani, sisalathiso esiphambili apho zonke ezinye izilinganiso zithathwa khona.
Abavelisi abanjengoZHHIMG baqinisekisa ukuba tyaba ngokuhambelana nemigangatho eyaziwayo kwihlabathi liphela efana ne-DIN 876 (eJamani), i-ASME B89.3.7 (e-USA), kunye ne-JIS B 7514 (eJapan). Le migangatho ichaza amanqanaba okunyamezela, aqhele ukuqala kwiBanga 00 (iBanga leLebhu, efuna ukuchaneka okuphezulu, rhoqo kuluhlu lwe-sub-micron okanye lwe-nanometer) ukuya kwiBanga 1 okanye 2 (iBanga loHlolo okanye leZixhobo). Ukufikelela ekubeni tyaba kwinqanaba lelebhu akufuneki nje kuphela uzinzo oluqhelekileyo lwe-granite enoxinano oluphezulu kodwa kunye nobuchule obukhethekileyo bee-lappers ezibalaseleyo—iingcali zethu ezinokufezekisa ezi mpawu ngesandla ngokuchanekileyo okubizwa ngokuba “yimvakalelo ye-micrometer.”
Ukuthe tye: Umqolo weSinyathelo esiLungileyo
Nangona ukuthe tye kubhekisa kwindawo enamacala amabini, ukuthe tye kusebenza kumgca othile, rhoqo ecaleni kwemiphetho, izikhokelo, okanye iindawo zenxalenye yegranite efana nomphetho othe tye, isikwere, okanye isiseko somatshini. Kuyilo lomatshini, ukuthe tye kubalulekile kuba kuqinisekisa indlela yokwenyani, ethe tye yee-axes zokuhamba.
Xa isiseko segranite sisetyenziselwa ukufaka izikhokelo ezithe ngqo okanye iibheringi zomoya, ukuthe tye kweendawo zokufaka kutshintsha ngokuthe ngqo impazamo ethe ngqo yesigaba sokuhamba, okuchaphazela ukuchaneka kokubeka kunye nokuphindaphinda. Iindlela zokulinganisa eziphambili, ngakumbi ezo zisebenzisa i-laser interferometers (inxalenye ephambili yeprotocol yokuhlola ye-ZHHIMG), ziyafuneka ukuqinisekisa ukuphambuka kokuthe tye kummandla wee-micrometers ngemitha nganye, ukuqinisekisa ukuba iqonga lisebenza njengomqolo ongenasiphako kwiinkqubo zokunyakaza eziguqukayo.
Ukufana kunye nokuLungelelanisa: Ukuchaza uBumbano lweJiyomethri
Kwizinto ezintsonkothileyo zegranite, ezifana neziseko zoomatshini, izikhokelo zomoya, okanye iindawo ezinamacala amaninzi ezifana nezikwere zegranite, izalathisi ezimbini ezongezelelweyo zibalulekile: Ukulingana kunye nokuGqibela (iSquareness).
- Ukuhambelana ngokulandelelana kuthetha ukuba iindawo ezimbini okanye ngaphezulu—ezifana neendawo zokufaka eziphezulu nezisezantsi zegranite beam—zikude kakhulu. Oku kubalulekile ekugcineni ukuphakama kokusebenza okungaguqukiyo okanye ukuqinisekisa ukuba izinto ezikumacala ahlukeneyo omatshini zilungelelaniswe ngokugqibeleleyo.
- Ukulingana, okanye isikwere, kuqinisekisa ukuba iindawo ezimbini zilingana ngokuchanekileyo ngama-90° omnye komnye. KwiCoordinate Measuring Machine eqhelekileyo (CMM), i-granite square ruler, okanye i-component base ngokwayo, kufuneka ibe nesiqinisekiso sokulingana ukuze kupheliswe impazamo ye-Abbe kwaye kuqinisekiswe ukuba ii-X, Y, kunye ne-Z axes zihambelana ngokwenene.
Umahluko we-ZHHIMG: Ngaphaya kweNkcazelo
Kwi-ZHHIMG, sikholelwa ukuba ukuchaneka akunakuchazwa ngokugqithisileyo—Ishishini lokuchaneka alinakuba nzima kakhulu. Ukuzinikela kwethu kudlula ukuhlangabezana nale migangatho ifanayo. Ngokusebenzisa i-ZHHIMG® Black Granite enobunzima obuphezulu (≈ 3100 kg/m³), amaqonga ethu ngokwemvelo anokuxinana okuphezulu kokungcangcazela kunye ne-coefficient yokwandiswa kobushushu ephantsi, ekhusela ngakumbi ukuthamba okuqinisekisiweyo, ukuthe tye, kunye nokufana kwimiba ephazamisayo yendalo kunye nokusebenza.
Xa uvavanya iqonga le-precision granite, jonga kungekuphela nje kwiphepha leenkcukacha kodwa nakwimeko yokwenziwa, iziqinisekiso, kunye nolawulo lomgangatho olulandelekayo—izinto kanye ezenza icandelo le-ZHHIMG® libe lolona khetho luzinzileyo noluthembekileyo kwizicelo ezifuna kakhulu ukuchaneka kwihlabathi.
