Kupfuura Slab: Granite Measuring Surface Plate Inova Sei Chiratidzo Chepamusoro CheMetrology Pasirose?

Mumakwikwi ari kuenderera mberi ekuenda kumuganhu we nanometer, zvinodiwa pakugadzira zvinhu zviri kukura zvakanyanya. Mainjiniya anogadzira masisitimu anochinja-chinja ane sub-micron feedback loops uye anoshandisa zvinhu zvisingawanzoitiki, asi chiyero chepamusoro chemhando chinowanzo enderana nehwaro huri nyore uye hwakagadzikana huripo: granite chaiyo.ndiro yekuyera pamusoro pegranite, inowanzo shanda seGranite Metrology Table, haisi chinhu chete; imhando chaiyo ye zero plane, nzvimbo isingachinjiki inosimbisa zvimwe zvikamu zvese musystem yakanyatsojeka.

Mhinduro yacho yakazara—inosanganisira ndiro yegranite ine hunyanzi hwepamusoro payo, ndiro yegranite ine rutsigiro, uye tafura yekuyera granite ine chigadziko—inomiririra kugadzikana kwenzvimbo yekugadzira zvinhu. Zvishandiso izvi ndizvo zvinodzivirira nyonganyonga yenzvimbo yekugadzira, zvichiita kuti mhedzisiro yekuyera itevedzerwe uye ive yakavimbika.

Fizikisi Isingaputsiki yeBlack Precision Granite Surface Plate

Kuvimba kusingazununguki kwakaiswa mugranite pamusoro pezvimwe zvinhu (sesimbi kana kongiri yepolymer) kwakavakirwa pazvinhu zviviri zvakakosha, zvisingashande: kugadzikana kwekupisa kwakanyanya uye kudzikamisa kwakanyanya kwekudengenyeka.

Kugadzikana kweThermal: Kubatsira kweCTE Yakaderera

Munzvimbo ipi zvayo inodzorwa nemamiriro ekunze, kuchinja-chinja kwekushisa kudiki hakudzivisiki. Kune zvishandiso zvesimbi, izvi zvinounza kusagadzikana kwehukuru hwazvo nekuda kwekuwedzera kwazvo kweCoefficient of Thermal Expansion (CTE). Furemu yesimbi inogona kushandura ma micrometer akati wandei pamusoro pekuchinja kudiki kwekushisa, zvichiita kuti kunyatsoita zvakanaka kukanganise.

Kunyatsojeka kwenhemamapuratifomu epamusoro egranite, kunyanya izvo zvinobva munzvimbo dzine huwandu hwakanyanya hwe geological (senge zvinhu zveZHHIMG zvinosvika 3100 kg/m³), zvine CTE yakaderera zvikuru. Hunhu uhwu hwezvinhu zvemukati hunovimbisa kuti shanduko yehukuru hwepamusoro hwekuyera inoderedzwa, zvichipa chiratidzo chinoramba chiri chechokwadi pasinei nekusiyana kwekupisa kwekunze. Uyezve, kusagadzikana kukuru kwekupisa kwegranite ine huwandu hwakawanda kunobatsira kuti irambe kupisa nekukurumidza, ichiva nechokwadi chekuti kupisa kunokonzerwa nekubata kana michina yekuyera hakukanganisi geometry yepamusoro.

Kuderedza Kushanda: Kunyaradza Zvakatipoteredza

Murabhoritari yemetrology, kururama kwemuchina kunofanira kuparadzaniswa kubva mukuzununguka kwepasi. Chimiro cheGranite chakaita sekristalline chinoipa simba rekudzivirira mukati, zvichireva kuti inotora simba remuchina nekukurumidza uye inorishandura kuita kupisa kushoma. Kana Zvishandiso zvekuyera zveGranite zvine resolution yepamusoro zvikaiswa paplate, granite inodzivirira kurira kwesimba, ichidzivirira ruzha rwezvakatipoteredza kuti rusakanganisa zviyero zvakapfava zvinoitwa neCMMs, optical profilers, kana laser interferometers. Iyi kinetic environment yakanyarara haigone kutaurwa nezvayo kuti iongororwe ne nanoscale.

Kubva paSlab kuenda kuSystem: Tafura yekuyera Granite ine Stand

Kunyange zvazvo granite slab pachayo ichipa kugadzikana, tafura yekuyera granite ine chigadziko inoshandura nzvimbo isingapindiki kuita nzvimbo inoshanda zvizere uye yakabatana yemetrology. Dhizaini yesystem yekutsigira yakakosha sezvakaita zvinhu zveplate.

Kubatanidzwa kweplate yepamusoro pegranite nerutsigiro kwakagadzirwa kuti ichengetedze hunhu hweplate hwakasimbiswa. Zvimiro zverutsigiro zvinowanzogadzirwa kuti zvienderane nemapoinzi eAiry akaverengerwa eplate kana mapoinzi eBessel, ayo ari mapoinzi akakodzera erutsigiro anogovera kushushikana zvakaenzana uye kuderedza kutsauka pamusoro pese. Kune maplate akakura zvakanyanya kana anorema, masisitimu ekutsigira akawanda-point anoshandiswa, anowanzo kuve netsoka dzinochinjika dzinochinjika kana mapedhi ekudzivirira akabatanidzwa.

Tafura yekuyera yegranite yemhando yepamusoro ine chigadziko inoita kuti plate yacho isatsvedzerere. Chero dambudziko riripo pakuoma kwechigadziko kana kuenzana kwacho rinoshanduka kubva pakukanganisika, zvichiita kuti plate yese isashande pabasa rayo nemazvo. Saka, sisitimu yese yetafura inowanzoonekwa seyuniti imwe chete, yakanatswa zvikuru yeGranite Metrology Table, yakaenzana zvakanaka uye yakasimbiswa panzvimbo yemutengi.

Nzvimbo yeZvishandiso zvekuyera Granite

Kushanda kweplate yekuyera yegranite kunowanikwa kuburikidza neGranite Measuring Tools. Zvishongedzo izvi—granite squares, straight edges, V-blocks, uye parallels—zvinofanirwa kugadzirwa nezvinhu zvakafanana zvegranite kuti zvive nechokwadi chekuti zvinhu zvakafanana panguva yese yekuyera. Izvi zvakakosha pakuchengetedza thermal equilibrium uye kugadzikana kwakafanana kwezvinhu zvese zvine chekuita nekuongorora.

Pakutarisa mativi echinhu chakaoma, semuenzaniso, kufanana kwegiraini yegiraini kana tichienzanisa nepuratifomu, kutwasuka kwegiraini yegiraini, uye kutwasuka kwepuratifomu yekuyera yegiraini zvinofanira kunge zvakanyatsorongeka uye zvichisimbiswa. Kugadzikana kwezvishandiso izvi—zvose zvichishandisa hunhu hwepamusoro hwegranite—kunovimbisa kuti zvikanganiso zvejometri zvakaonekwa zvikanganiso zviri muchikamu chebasa, kwete sisitimu yekuyera.

Simba reMagiredhi uye Unyanzvi hwekugadzira

Kugadzirwa kweplate yegranite nhema yepamusoro-soro yepamusoro-soro kunopfuura kugadzirwa chete; kunoda musanganiswa wetekinoroji yepamusoro uye hunyanzvi hwevanhu husingaverengeki.

1. Kugona Kwakakura: Vatengesi vanotungamira vanofanira kunge vaine zvivakwa zvekugadzirisa mapuratifomu makuru emetrology pasi rose, zvinoda michina yeCNC inokwanisa kubata zvinhu zvinodarika matani zana uye kureba kwemamita makumi maviri.

2. Kunyatsosimbiswa: Kusatsetseka kwekupedzisira kunowanikwa kuburikidza nemaitiro akaoma ekurovera nemaoko, anoitwa nenyanzvi dzehunyanzvi dzine ruzivo rwemakumi emakore. Kugona kwavo kusvika paGiredhi 00 kana kuti Giredhi A kusatsetseka, kunoyerwa muzvikamu zve micron kana nanometers, kunosimbiswa uchishandisa maturusi akaomarara akadai se laser interferometers, ese anoteverwa nemazinga epasi rose (NIST, PTB, NPL).

3. Kutevedzera Mutemo Wepasi Pose: Sisitimu yemhando yepamusoro inofanirwa kuve yakatenderwa zvichienderana nezvinodiwa zvepasi rose (ISO 9001, 14001, 45001) uye inokwanisa kutenderwa nemaplates zvichienderana nezvinodiwa zvakasiyana-siyana, zvinosanganisira DIN, ASME, JIS, uye GB, zvichiita kuti Granite Metrology Table ikwane nezvinodiwa zvakanyanya pasi rose.

Kugara kwenguva refu uye simba rezvishandiso zvekuyera zveGranite zvinoratidza musimboti mukuru: munguva yekushandiswa kwemagetsi, chokwadi chejometri chinofanira kugara chisina kusimba, chakagadzikana, uye chinoteverwa. Puratifomu yepamusoro yegranite ine rutsigiro, inoshanda senzvimbo yekupedzisira isina kutaurwa, inoramba iri hwaro husingazununguki hwese hwehunyanzvi muinjiniya yehunyanzvi hwepamusoro-soro.
