Munyika yekugadzira zvinhu nemazvo, kuyerwa kwese kunoda "zero point" -- purani yakavimbika, yakati sandara zvakakwana iyo mimwe miganhu yese inobva. Kwemakore anopfuura makumi mashanu, granite surface plate yave ichishandiswa senzira huru yekureva. Zvisinei, kana zvasvika pakushongedza imba yekuongorora kana shopu yemichina, mumwe wemibvunzo inowanzo bvunzwa haisi yehukuru hweplate, asi yeGrade.
Kusarudza giredhi rakakodzera inzira yekuenzanisa pakati pekururama kunodiwa nemapurojekiti ako uye mamiriro ezvinhu enzvimbo yako yebasa. Kusarudza giredhi rakaderera zvakanyanya kunogona kukanganisa kutonga kwako kwemhando, nepo kusarudza giredhi rakakwirira zvisingaite kunogona kukonzera matambudziko emari yakawanda uye kugadzirisa. Kuti uite sarudzo ine ruzivo, zvakakosha kunzwisisa kuti giredhi idzi dzinomiririrei chaizvo uye kuti dzinoshanda sei munyika chaiyo.
Kunzwisisa Kururama: Kunzwisisa Kushivirira Kweparutivi
Magiredhi eplate yepamusoro haasi mazita asina kurongeka; anotsanangurwa zvakanyanya nemiyero yepasi rose (yakadai seASME B89.3.7 kana ISO 8512-2). Mitemo iyi inorayira "Chikanganiso Chinobvumidzwa" chekuva yakati sandara pamusoro pese. Patinotaura nezvekuti sandara muchirevo ichi, tiri kureva chinhambwe chiri pakati penzvimbo mbiri dzakafanana dzinofukidza misoro yese nemipata yedombo.
Indasitiri iyi inowanzoisa maplate muzvikamu zvitatu zvekutanga:
-
Giredhi AA (Giredhi reLaboratory): Muyero wepamusoro-soro, unowanzo chengeterwa marabhoritari anodzorwa nekupisa.
-
Giredhi A (Giredhi reKuongorora): Madhipatimendi ekuongorora mhando anoshanda nesimba, achipa mwero wepamusoro wekururama pakuongororwa kwakajairika.
-
Giredhi B (Giredhi reMidziyo): Yakagadzirirwa pasi pechitoro, uko marongero ekutanga uye kuongororwa kwakaoma kunoitika.
Musiyano wekutsetseka pakati pemagiredhi aya unoyerwa muma micrometer (microns). Semuenzaniso, ndiro diki reLaboratory Grade AA rinogona kunge rakatsetseka re2.5 microns, nepo ndiro reToolroom Grade B rehukuru hwakafanana rinogona kubvumira ma microns gumi. Kunyange zvazvo nhamba idzi dzichiita sediki, dzinova chinhu chikuru kana uri kuisa magage blocks kana kushandisa ma electronic indicators ane resolution yepamusoro.
Giredhi AA: Muyero weLabhoritari
Kana nzvimbo yako ichishanda mukugadzira zvinhu zvemuchadenga, kugadzira zvishandiso zvekurapa, kana kugadzira semiconductor, Giredhi AA ingangove ndiyo yaunoda. Maplate aya akagadzirirwa "kuongororwa" zvakanyanya. Nekuti kushivirira kwawo kwakasimba, maplate eGiredhi AA anonyanya kugadzikana nemamiriro ekunze.
Pureti yeGiredhi AA inongoenderana nekamuri rayo chete. Murabhoritari yemetrology, tembiricha inowanzo chengetwa pa20℃ (68℉). Kana waizoisaPlate yeAA yegiredhiPachikuva chechitoro chine mhepo inotonhorera pedyo nemusuwo wakavhurika, kupenya kwekupisa—musiyano wekupisa pakati pepamusoro nepasi pedombo—kwaizokonzera kuti ndiro yacho ikotama zvakakwana kuti ibve pane zvinodiwa zveGiredhi AA mukati memaminitsi mashoma. Saka, unofanira kusarudza Giredhi AA chete kana uine nzvimbo inodzorwa yekuchengetedza mari yako.
Giredhi A: Bhiza reKuongorora
Kune vazhinji vezvitoro zvemichina yekunyora nemazvo, Giredhi A ndiyo sarudzo ine musoro. Inopa kururama kunodiwa pakusimbisa zvikamu zvinogadzirwa pamichina yeCNC pasina "kuoma" sematombo eGiredhi reLaboratory. Maplate eGiredhi A akakodzera kushandiswa negeji dzehurefu, sine bars, uye coordinate measuring machines (CMMs) munzvimbo yakatarwa yekuongorora iyo, kunyange zvazvo isiri "nzvimbo yakachena," inochengetwa patembiricha yakadzikama.
Giredhi A rinopa "nzvimbo yakanaka" maererano neROI. Rinopa kunyatsojeka kwakakwana kuzadzisa zvinodiwa zveISO 9001 uku richiramba rakasimba zvakakwana kuti rishandiswe zuva nezuva nevanozivana vakawanda.
Giredhi B: Kururama Kwakasimba kweToolroom
Mapureti eGiredhi B ndiwo magamba asingaimbwe ekugadzira. Mapureti aya akagadzirirwa kushandiswa panzvimbo iri kuitirwa basa racho. Akakora uye akasimba, akagadzirirwa kutakura huremu hwezvinhu zvakagadzirwa zvisina kugadzirwa kana zvinhu zvinorema.
Kunyange zvazvo usingashandise plate yeGiredhi B kugadzirisa magage blocks ako, zvakakwana pakutarisa marongerwo echikamu kana kusimbisa gadziriro yacho usati waita machine kwenguva refu. Chinhu chikuru cheGiredhi B ndechekuti inotsungirira; inopa nzvimbo yakagadzikana uye yakarurama kupfuura bhenji resimbi, asi haidi "magirovhosi machena" ekugadzirisa nzvimbo yeAA-grade.
Zvinhu Zvikuru Zvekufunga Nezvekusarudza
Paunenge uchisarudza kuti uchatenga giredhi ripi, zvibvunze mibvunzo mitatu inotevera:
-
Chii chandinonyanya kushivirira? Mutemo unowanzo shandiswa ndewekuti chiyero che10:1. Chishandiso chako chekuyera (kusanganisira plate yepamusoro) chinofanira kunge chakarurama zvakapetwa kagumi pane chikamu chauri kuyera. Kana kutsungirira kwechikamu chako kuri ± 0.01 mm, puratifomu yako yepamusoro inofanira kunge yakarurama kusvika ku0.001mm.
-
Plate iyi ichagara kupi? Sezvambotaurwa, nharaunda ndiyo muvengi mukuru wekururama. Plate dzemhando yepamusoro dzinoda kugadzikana kwekupisa. Kana imba yako yekuongorora ichikanganiswa nezuva richirova plate kana mamhepo anotonhodza mweya achivhuvhuta zvakananga pairi, plate yeGrade AA ingasambogara yakati sandara.
-
Huremu hwezvikamu zvacho hwakaita sei? Zvikamu zvinorema zvinogona kukonzera "kurema kwenzvimbo" uye kutsauka. Kunyange zvazvo giredhi richireva kuti rakati sandara, maplate epamusoro anowanzoda kutariswa kakawanda kana akaiswa mutoro unorema unogona kupwanya nzvimbo dzakati dzedombo nekufamba kwenguva.
Mhedziso: Nheyo yeKuvimba
Purati yegranite pamusoro haisi dombo chete; ndiyo hwaro hwekuvimba kwemutengi wako. Kunyangwe ukasarudza kunyatsoita Grade AA, kuvimbika kweGrade A, kana kushanda kwakasimba kweGrade B, chinhu chikuru ndechekuva nechokwadi chekuti puratifomu yacho inoongororwa nguva dzose uye inochengetwa zvakanaka.
Nekunzwisisa hunhu hwehunyanzvi hwemagiredhi aya, unogona kuva nechokwadi chekuti imba yako yekuongorora yakashongedzerwa kugadzirisa matambudziko ekugadzira zvinhu zvemazuva ano pasina kushandisa mari yakawanda pazvinhu zvisina basa.
