DIN, JIS, GB, ASME: Gwaro Rinoshanda reMatanho eGranite Surface Plate

Vatengi vanoenzanisa mapuratifomu egranite kubva kuvatengesi vakasiyana vanowanzosangana nedambudziko risinganzwisiswi: mapuratifomu maviri anogona kutaura kuti "Giredhi 0″ kana "Giredhi AA" akarurama asi asingarevi chinhu chimwe chete, nekuti ari kureva mitemo yakasiyana yenyika ine mafomula akasiyana ekushivirira. Gwaro iri rinotsanangura zvinonyatsotsanangurwa nemitemo mikuru uye kuti nei musiyano wacho uchikosha paunenge uchitsvaga michina.

Sei pasina mwero mumwe chete wepasi rose

Mapureti epamusoro egranite akagadziriswa zvichienderana nekuremara kwakatsetseka kunoyera nehukuru hweplate — plate ye1600mm neplate ye300mm zviri pachena kuti haigone kutakura kuremara kwakafanana. Nyika dzakasiyana dzakagadzira mafomura adzo ekuyera uku, kazhinji panguva imwecheteyo yekugadzirwa kwemaindasitiri:

• Germany — DIN 876 ingangove ndiyo chiyero chinonyanya kutaurwa pasi rose, ichitsanangura kurongeka kwemagiredhi 00, 0, 1, uye 2, uye giredhi 00 ndiyo yakanyanya kusimba. DIN 875 uye DIN 650 ine chekuita negranite tooling geometry.
• United States — Federal Standard GGG-P-463c uye ASME B89.3.7 yemazuva ano inotsanangura mamakisi AA, A, uye B emapuratifomu epamusoro, kare ndiyo yakajairika mumarabhoritari emetrology ekuAmerica nezvitoro zvemichina zvinoongorora.
• Japan — JIS B 7513 inogadza sisitimu yayo yemhando yepamusoro, inowanzo taurwa nezvemichina yakavakirwa kana kutumirwa kune vagadziri vekuJapan, kunyanya muchikamu chekutengesa che semiconductor.
• China — GB/T standards, iyo yave pedyo netsika dzepasi rose mumakore achangopfuura sezvo michina yakagadzirwa neChina yakanyatsogadzirwa ichibatsira misika yekutengesera kunze kwenyika.
• United Kingdom — BS 817, Russia — GOST 10905, neFrance — NF standards dzinopedzisa runyorwa rwemitemo ichiri kutaurwa zvichienderana nenyika yemuchina kana kwawakabva.

Chii chakasiyana pakati pavo?

Kusawirirana kukuru pakati pemitemo hakusi kwepfungwa - ndiyo fomura yemasvomhu inoshandiswa neumwe neumwe kuverenga kupatsanurwa kwakanyanya kunobvumirwa kwe flatness zvichibva pakureba kwe diagonal kweplate. Plate yeDIN 876 Grade 0 ne JIS Grade 1 plate yehukuru hwakafanana zvinogona kuguma nekushivirirana kuri pedyo asi kusina kufanana. Kune akawanda mashandisirwo emaindasitiri musiyano wacho hausi webasa. Kune ma metrology labs anoita traceable calibration, kana kune michina yakagadzirirwa mutengi anoda DIN kana JIS certification, hazvisi izvo.

Ndosaka, pakutsvagazvikamu zvegranitePakutumira kunze kwenyika, zvakakosha kubvunza mutengesi kuti chitupa chekuongorora chiri kutaurwa nezvechipimo chipi - kwete chete kuti nhamba yegiredhi ripi rinoonekwa pamapepa. Chikumbiro che "Giredhi 0" chisina mwero wakanyorwa hachigone kusimbiswa.

Kutevedzana: chikamu chiri nyore kusvetuka

Chitupa chekuongorora chinoshanda chete secheni iri shure kwacho. Chishandiso chinoshandiswa kuyera ndiro — electronic level, autocollimator, laser interferometer — chaifanira kunge chakaongororwa nesangano re metrology rakagamuchirwa, uye kuongorora ikoko kunofanira kuteverwa kudzokera kuchiyero chenyika. Muchokwadi, izvi zvinoreva kukumbira:

1. Chitupa chekugadzirisa plate kana chikamu chaicho, chichitaura kuti ndechipi chiyero (DIN/JIS/GB/ASME/etc.) chakashandiswa.
2. Chitupa chekugadzirisa chinoshandiswa pakuyera, chakapihwa nesangano rinozivikanwa remetrology.
3. Kutaura kwakajeka kwekusaziva kwekuyera, kwete kungopasa/kukundikana chete.

Chimwe chinodarika izvi ndechekuti dzimwe nguva "zvikumbiro zveGiredhi 0" zvakabvumidzwa zvinobuda zvega nefekitori pasina kusimbiswa kwevamwe - kwete zvenhema, asi hazvina zvazvinorevawo.

Chinyorwa chinoshanda kumapoka ekutenga zvinhu

Kana michina yako ichitengeswa kumisika yakasiyana-siyana, zvinowanzokosha kukumbira kuenzaniswa kaviri - semuenzaniso, nhamba dzeDIN 876 neJIS B 7513 - pane kufunga kuti imwe standard inoshandura imwe zvakanaka. Zvinodhura zvakanyanya munguva yekuenzanisa, asi zvinobvisa kusanzwisisika kwemutengi wekupedzisira, kunyanya mumaindasitiri akaita se semiconductor nekugadzira mota uko dhipatimendi remhando yemutengi wekupedzisira richakumbira magwaro akajairwa.
