Mbale ya granite pamwamba ndi ndalama zogulira ndalama kwa nthawi yayitali, tanthauzo lenileni la chuma cholimba m'dziko la metrology. Komabe, chida chofunikira ichi sichimawonongeka, kuwonongeka, kapena kutayika kosatha pakapita nthawi. Kwa woyang'anira aliyense wowongolera khalidwe, kumvetsetsa osati kusankha koyenera kwa mbale yowunikira granite pamwamba komanso njira zokonzera mbale ya granite pamwamba ndikofunikira kwambiri kuti muchepetse nthawi yogwira ntchito ndikusunga kulondola. Chiyembekezo chakuti mbale ya pamwamba, kaya ndi mbale ya granite yayikulu kapena mtundu wina wotsogola, isungabe kusalala kwake kosatha ndizosatheka.
Mmene Granite Ikugwirira Ntchito: Chifukwa Chake Kukonza Granite Surface Plate Kumakhala Kofunikira
Chifukwa chachikulu chomwe granite plate imafunika kukonzedwa ndi kuwonongeka kwa malo. Ngakhale granite wakuda wolimba kwambiri amagonjetsedwa ndi kukangana kosalekeza kuchokera ku zida zoyezera, zida zogwirira ntchito, ndi tinthu ta fumbi tomwe timayabwa. Kuwonongeka kumeneku nthawi zambiri kumawonekera m'malo owonongeka kwambiri, omwe amapezeka pomwe zida monga ma gauge a kutalika zimayikidwa ndikusunthidwa nthawi zambiri, zomwe zimapangitsa kuti zikhale zovuta kuwerenga momwe zimabwerezedwera. Ichi nthawi zambiri chimakhala chizindikiro choyamba chakuti kukonza granite pamwamba pa plate kungafunike. Kuphatikiza apo, kuwonongeka mwangozi m'mphepete kapena ngodya za plate kungayambitse kusweka; pomwe zidutswa zomwe zili kutali ndi malo ogwirira ntchito sizingakhudze mwachindunji kusweka, zimatha kuwononga umphumphu wa kapangidwe kake ndikuwonetsa kugwirira ntchito molakwika. Kuphatikiza apo, pakapita zaka zambiri zogwiritsidwa ntchito kwambiri, plate yonseyo imatha kugwa pang'onopang'ono kuchokera pa grade yake yovomerezeka (monga, plate ya Giredi 0 ikhoza kuchepa kufika pa grade 1 tolerance). Izi zimafuna kukonzanso kwathunthu. Ngati kulekerera kofunikira pantchito yowunikira sikukwaniritsidwanso, yankho silosintha, koma njira yapadera yokonzanso yotchedwa re-lapping kapena resurfacing. Izi zimaphatikizapo akatswiri aluso kwambiri omwe amachotsa mosamala malo okwera pa plate pogwiritsa ntchito mankhwala okhwima ndi ma master reference plates akuluakulu, kubweretsa kusweka mkati mwa kulekerera kovomerezeka. Utumiki wapaderawu umawonjezera nthawi ya moyo wa mbaleyo kwamuyaya, zomwe zimapangitsa kuti ikhale gawo lofunika kwambiri pa kasamalidwe ka zida za metrology.
Muyezo Wagolide: Kodi Muyezo wa Granite Surface Plate ndi Chiyani?
Kuti munthu azitha kuyang'anira bwino labotale ya metrology, choyamba ayenera kufotokoza zomwe zili muyeso wa kulondola kwa granite pamwamba pa mbale. Muyeso uwu ukutanthauza magiredi olekerera padziko lonse lapansi (AA, 0, ndi 1) omwe adakhazikitsidwa ndi ma specifications monga US Federal Specification GGG-P-463c kapena German DIN 876. Mapepala awa amalamula kupatuka kwakukulu kovomerezeka kuchokera ku ndege yangwiro, kuonetsetsa kuti magawo ndi miyeso zimasinthana padziko lonse lapansi. Komabe, muyeso weniweni umaphatikizaponso filosofi ya kupeza zinthu zodalirika. Opanga monga granite pamwamba pa mbale yayikulu kapena mitundu ina yodziwika bwino amatsatira njira zowongolera khalidwe, osati pongopeza kusalala koyambirira komanso potsimikizira mtundu wa granite wakuda wosaphika - kuonetsetsa kuti uli ndi quartz yochepa, kuchuluka kwakukulu, komanso kuchuluka kochepa kwa kutentha (CTE) kuti isasinthe mawonekedwe chifukwa cha kusinthasintha kwa kutentha. Granite yowunikira pamwamba yomwe yagulidwa kuchokera kwa ogulitsa odalirika imakhala ndi chitsimikizo chakuti zinthuzo ndizoyenera kugwira ntchito molondola kwambiri.
Kukonzekeretsa Kuyang'aniridwa: Ntchito ya Granite Surface Plate yokhala ndi Chizindikiro Choyimira
Ntchito yaikulu yomwe imachitika pa granite test surface plate ndi kuyeza koyerekeza, komwe muyezo wodziwika bwino (gage block) umagwiritsidwa ntchito kukhazikitsa geji, ndipo workpiece imayesedwa motsutsana ndi kukula komweko. Njirayi nthawi zambiri imagwiritsa ntchito granite surface plate yokhala ndi chizindikiro. Chizindikiro, chomwe nthawi zambiri chimakhala ndi mzati wolimba wokhazikika pa maziko a maginito kapena makina, chimakhala ndi chizindikiro choyesera dial kapena digito probe. Kukhazikika kwake ndikofunikira kuti muyese molondola. Ngakhale kuti ma gauge osavuta a mzati amatha kusunthidwa mozungulira mbaleyo, kukhala ndi mbale yopangidwa mwapadera kuti iphatikize zida izi kumapangitsa kuti njira yowunikira ikhale yosavuta. Granite surface plate yokhala ndi chizindikiro nthawi zambiri imatanthauza kukhazikitsa kosatha, kokhazikika kwambiri, nthawi zina kugwiritsa ntchito zoyika ulusi mkati mwa mbale kuti zigwirizane ndi chithunzicho mwachindunji, kuchotsa kuyenda pang'ono kapena kupendekera komwe kungatheke ndi maziko a maginito. Kuphatikiza apo, granite imapereka datum yoyenera yokhazikitsira chizindikiro cha zero point pogwiritsa ntchito gage block, ndipo chizindikirocho chimasunga kutalika ndi perpendicularity, kuonetsetsa kuti miyeso yoyerekeza imabwerezedwanso, yomwe ndi maziko a metrology yowunikira. Kuphatikiza kumeneku kwa nsanamira yokhazikika ndi mbale yovomerezeka yowunikira ya granite kumapangitsa kuti njira yonse yoyezera ikhale yolondola, kusintha slab yosavuta kukhala malo oyezera okwanira komanso olondola kwambiri.
Kusunga Umphumphu wa Granite Inspection Plate
Chisamaliro chodzitetezera nthawi zonse chimakhala chotsika mtengo kuposa kukonza mbale ya granite pamwamba. Ngakhale kuti kuwonongeka sikungapeweke, kuchuluka kwake kumatha kuchepetsedwa kwambiri pokonza bwino nyumba. Mdani wamkulu wa mbale ndi fumbi ndi matope, zomwe zimagwira ntchito ngati matope oundana pansi pa zida. Ogwiritsa ntchito ayenera kuyeretsa mbaleyo mosamala asanayambe kugwiritsa ntchito komanso atamaliza kugwiritsa ntchito ndi chotsukira mbale chapadera, ndipo osakoka zinthu zolemera pamwamba pake. Pomaliza, kudzipereka ku khalidwe la metrology kumatanthauza kuvomereza moyo wofunikira wa zida izi: kusankha mosamala, kugwiritsa ntchito, kukonza nthawi, komanso kukonza mbale ya granite pamwamba pake. Potsatira mfundo yakuti kutsatira kwambiri miyezo yoyezera ndiye muyezo wa mbale ya granite pamwamba, akatswiri owongolera khalidwe amateteza kulondola kwa muyeso uliwonse womwe umathandizira kuti chinthucho chikhale cholondola.
