Mumunda wekuyera kuyerwa, granite yakatwasuka, sechishandiso chakakosha chekuvimbisa kurongeka kwemidziyo uye kuyerwa, giredhi rayo reflatness rinokanganisa zvakananga kuvimbika kwemhedzisiro yekuyera. National Institute of Standards and Technology (NIST) certification yeUnited States chiyero chinozivikanwa pasi rose chepamusoro-chaizvo zvekuyeresa michina, uye AA-level flatness ndeimwe yemagiredhi ane yakanyanya kurongeka zvinodiwa. Semhando inotungamira muindastiri, ZHHIMG, nehunyanzvi hwayo hwepamusoro uye hunyanzvi hwekuita, inobatsira vashandisi kuwana chitupa cheNIST uye AA-level flatness zvinangwa zvegranite straighteers. Izvi zvinotevera zvinokupa iwe ongororo yakadzama yecalibration kiyi mapoinzi uye nzira dzekuita.
1. Nzwisisa NIST certification uye AA-level flatness standard
NIST certification ine mukurumbira mukuyedza kwayo uye maitiro ekuongorora, nechinangwa chayo chikuru kuve kuona kuti michina yekuyera inosangana neinotungamira pasirese mwero. Mumunda wegranite straightedge, iyo AA giredhi flatness inodiwa yakanyanya kuomarara. Kazhinji, zvinotarwa kuti chikanganiso cheflatness mukati mehurefu hwemamita yega yega chinofanira kudzorwa mukati me ± 0.5μm. Iyi chiyero inoisa kumberi zvakanyanyisa zvinodikanwa zvezvinhu zvezvinhu, kugadzirisa tekinoroji uye calibration tekinoroji yeiyo straightedge. Iyo AA-level granite straightedge yakasimbiswa neNIST haingori vimbiso yakavimbika yekuyerwa kwepamusoro-soro, asiwo humbowo hwakasimba hwekusimba kwebhizinesi rehunyanzvi uye mhando yechigadzirwa.
Ii. Iyo Quality Foundation yeZHHIMG granite yakatwasuka
Iyo ZHHIMG granite yakatwasuka yakaisa yakakwira-chaiyo hwaro kubva padanho rekusarudza zvinhu. Yakasarudzwa yemhando yepamusoro yegranite yemhando yepamusoro, ine dense yemukati mineral crystallization uye yunifomu chimiro, ine yekupisa yekuwedzera coefficient yakaderera se5-7 × 10⁻⁶/℃, uye ine kugadzikana kwechisikigo uye anti-deformation kugona, ichipa mukana wekuzvarwa wekuwana AA-level flatness. Munguva yedanho rekugadzirisa, ZHHIMG inoshandisa hunyanzvi hwepamberi senge CNC kukuya nekupukuta, yakasanganiswa neyakajeka-chaiyo yekuona michina senge laser interferometers yechaiyo-nguva calibration, kuve nechokwadi chekuti pamusoro peiyo straighteer inowana yakanyanya kukwirira kwekutanga kurongeka panguva yekugadziriswa, ichigadzira mamiriro akanaka einotevera calibration basa.
Iii. Gadziriro Pamberi Pekugadziriswa
Usati waitisa NIST certification calibration, zvinodikanwa kuti uone kuti kutwasanuka kuri muchimiro chepamusoro. Chokutanga pane zvose, pamusoro peiyo yakatwasuka inofanira kucheneswa zvakadzama. Shandisa jira-risina-lint uye yakakosha yekuchenesa kubvisa mafuta mavara, guruva uye zvimwe zvitsvina pamusoro kudzivirira kusvibiswa kunokanganisa iko calibration. Chechipiri, isa iyo yakatwasuka munzvimbo ine tembiricha inogara uye hunyoro kweanopfuura maawa makumi maviri nemana kuibvumira kuti ienderane zvizere nekupisa kwezvakatipoteredza uye hunyoro, ichibvisa diki deformations inokonzerwa nekuchinja kwezvakatipoteredza. Uye zvakare, yakakwirira-chaiyo calibration maturusi akadai se laser interferometers uye mazinga emagetsi anoda kugadzirirwa. Kurongeka kwezvishandiso izvi kunokanganisa zvakananga kurongeka kwemhedzisiro yecalibration.
Iv. Calibration Maitiro uye Key Technologies
Rough calibration: Shandisa chiyero chemagetsi kuita kuyerwa kwekutanga kwekutwasanuka. Unganidza nzvimbo yekuyeresa pane dzimwe nguva (senge 100mm) kuti uwane dhata rekuyera renzvimbo yakatwasuka. Zvichienderana nemhedzisiro yekuyerwa, pamusoro peiyo yakatwasuka yakanyatsogadzirwa kuburikidza neCNC yekukuya michina kuti ibvise zviri pachena mapoinzi, zvichiita kuti flatness itange yasvika kuAA-level zvinodiwa.
Precision calibration: Kuyera kwepamusoro-soro kunoitwa uchishandisa laser interferometer, iyo inogona kunyatsoona kushanduka kwehurefu pamusoro peiyo yakatwasuka padanho re micrometer. Kubva pane iyo data yakadzoserwa neiyo interferometer, pamusoro peiyo yakatwasuka yakanyatso kuvhurika nekubatanidza manyore kugaya neCNC machining. Munguva yekukuya, kudzvinyirirwa uye kutungamira kunoda kugara kuchigadziriswa kuti zvishoma nezvishoma kubvisa kukanganisa kweflatness, kuitira kuti kutaridzika kwepamusoro kweiyo straightedge kunogona kusvika kune yakakwirira.
Kudzokororwa kudzokororwa uye kugadzirisa zvakanaka: Mushure mekupedza iyo yakanaka calibration, shandisa laser interferometer uye yemagetsi nhanho kuita ongororo yakazara yekutwasanuka zvakare kuti uve nechokwadi chekuti chikanganiso che flatness cheyero imwe neimwe yekuyera iri mukati meiyo AA-level standard renji. Kana zvikanganiso zvidiki zvikawanikwa munzvimbo yenzvimbo, kukwenenzvera kwakanangwa kunofanirwa kuitwa kudzamara kuwanda kwese kwekwese kwazadzikisa zvizere zvinodiwa neAA-level yeNIST certification.
V. NIST Certification Application uye Ongororo
Mushure mekupedza calibration uye nekusimbisa kuti kutwasanuka kwawana AA-level flatness, unogona kuendesa certification application kuNIST. Munguva yemaitiro ekunyorera, yakadzama tekinoroji ma paramita eiyo straightedge, kugadzirisa tekinoroji tsananguro, calibration marekodhi uye zvimwe zvinhu zvinofanirwa kupihwa. NIST ichatumira vaongorori vehunyanzvi kuti vaite ongororo pa-saiti uye ongororo yekutwasuka. Ongororo yacho ichavhara akawanda maficha senge flatness, kugadzikana kwekupisa, uye kupfeka kuramba kweiyo yakatwasuka. Chete granite straightedge iyo yakapfuura ongororo yakasimba ndiyo inogona kuwana NIST certification uye kuva benchmark chigadzirwa mumunda wekuyera chaiko.
Nekutevera zvadudzwa pamusoro ZHHIMG granite straightedge calibration nhungamiro, mabhizinesi nemasangano ekutsvagisa anogona kuwana chitupa cheNIST uye AA-level flatness zvinangwa zvakanyanya. Zvingave mumaindasitiri ane zvakanyanyisa hunyanzvi zvinodiwa sekugadzira michina, aerospace, kana machipisi emagetsi, iyo ZHHIMG granite straightedge yakasimbiswa neNIST ichava mubatsiri akavimbika mukuona kuyerwa kwakaringana uye kunaka kwechigadzirwa, zvichibatsira mabhizinesi kuramba achipaza mumunda wekuyera uye kuenda kune ramangwana rechokwadi chepamusoro.
