Kana ukapinda muchitoro chemichina chakanyatsogadzirwa, murabhoritari yekuongorora, kana munhandare yendege muEurope kana North America, unogona kuwana chinhu chaunowanzoona: dombo rakasviba, rakapoteredzwa regranite rinoshanda sehwaro hwechinyararire chekuyera kwakakosha. Iri ndiro Granite Surface Plate—dombo guru remetrology kwemakore anopfuura makumi mashanu. Asi heino mubvunzo unobvunzwa nevashoma: ndiro iyoyo inopa kururama kwayakagadzirirwa here, kana kuti mashandiro ayo ari kukanganiswa chinyararire nekuisa kwayo, kutsigirwa kwayo, uye kutarisirwa kwayo?
Chokwadi ndechekuti,Granite Pamusoro PlateHazvisi kungori dombo rakati sandara. Chinhu chakagadzirwa chakagadziriswa—chiratidzo chechokwadi chejometri. Asi vashandisi vazhinji vanochibata sefenicha: chakasungirirwa pafuremu isina kusimba, chakaiswa pedyo nechinhu chinopisa, kana kusiiwa chisina kugadziriswa kwemakore vachifunga kuti "granite haichinji." Kunyange zvazvo chiri chokwadi kuti granite inopa kugadzikana kwakanyanya kana tichienzanisa nesimbi, haisi kudzivirirwa pakukanganisa. Uye kana ikabatanidzwa nezvishandiso zvinonzwa senge mageji ekukwirira, zviratidzo zvekudhirowa, kana maekisesaizi ekuona, kunyangwe kutsauka kwema micron gumi kunogona kukonzera kusanzwisisana kunodhura.
Apa ndipo panonyanya kukosha musiyano uripo pakati peplate isina chinhu nesystem yakazara. Granite Surface Plate ine stand haisi yekungorerutsira chete—inongova yekusimba kwemetrological. stand haisi chinhu chinobatsira; chinhu chakagadzirwa neinjiniya chinoita kuti plate irambe yakati sandara, yakagadzikana, uye iri nyore kusvika mumamiriro ezvinhu chaiwo. Pasina iyo, kunyangwe granite yepamusoro-soro inogona kudonha, kudedera, kana kuchinja—zvichikanganisa kuyerwa kwese kwainoitwa pairi.
Ngatitangei nezvinhu zvacho pachazvo. Granite nhema yemhando yeMetrology—inowanzo torwa kubva mumagwenga emuIndia, China, kana Scandinavia—inosarudzwa nekuda kwechimiro chayo cheisotropic, kuwedzera kwekupisa kwakaderera (kusvika 6–8 µm/m·°C), uye hunhu hwayo hwekunyorovesa mvura. Kusiyana nesimbi yakakandwa, iyo inoita ngura, inoramba ichiita machining stress, uye inowedzera zvakanyanya nekupisa, granite inoramba yakafanana munzvimbo dzese dzebasa. Ndosaka mitemo yepasi rose yakaita seASME B89.3.7 (US) neISO 8512-2 (pasi rose) ichitsanangura granite seyega chinhu chinogamuchirwa chemaplate epamusoro anoshandiswa pakuenzanisa nekuongorora.
Asi zvinhu chete hazvina kukwana. Funga izvi: Granite Surface Plate yakajairika ye1000 x 2000 mm inorema anenge 600–700 kg. Kana ikaiswa pauriri husina kuenzana kana furemu isina kuomarara, simba rinokwevera pasi chete rinogona kukonzera kutsauka kudiki—kunyanya pakati. Kutsauka uku kunogona kusaonekwa neziso asi kunoyerwa neinterferometry, uye kunokanganisa zvakananga kushivirira kugadzikana. Semuenzaniso, plate yeGiredhi 0 yehukuru ihwohwo inofanira kuchengetedza kugadzikana mukati me ±13 microns pamusoro payo yese zvichienderana neISO 8512-2. plate isina kutsigirwa zvakanaka inogona kupfuura izvozvo—kunyangwe granite pachayo yakakwenenzverwa zvakanaka.
Ndiro simba—uye kukosha—kwechinangwa chakavakirwaGranite Pamusoro Platenechigadziko. Chigadziko chemhando yepamusoro chinoita zvinopfuura kungosimudza plate kusvika pakukwirira kwayo (kazhinji 850–900 mm). Chinopa rutsigiro rwakanyatsorongwa rwemapoinzi matatu kana akawanda rwakabatana nepfungwa dzechisikigo dzeplate kudzivirira kukotama. Chinosanganisira kubatanidza kwakasimba kuti chisatendere kutenderedzwa. Mazhinji anosanganisira tsoka dzinodedera kana kuti zvinosungirirwa kuti zvidzivirire kubva pakukanganiswa nepasi kubva kumichina iri pedyo. Mamwe anotova nema terminals ekudzika pasi kuti abvise static - inokosha mumagetsi kana maapplication ekuchenesa.
KuZHHIMG, takashanda nevatengi vaifunga kuti granite plate yavo yaive "yakanaka zvakakwana" nekuti yaitaridzika zvakanaka uye yakanga isina kutsemuka. Mumwe mutengesi wemotokari kuMidwest akawana kuti maburi akaenzana zvakanaka pamagetsi emagetsi. Mushure mekuferefeta, mhosva yacho yakanga isiri CMM kana mushandi - yaive furemu yesimbi yakagadzirwa kumba yaichinjika pasi pemutoro. Kuchinja kuenda kuGranite Surface Plate ine chitupa, yakagadzirwa zvinoenderana nemirairo yeASME, kwakabvisa musiyano uyu husiku hwese. Kuwanda kwezvimedu zvavo kwakadzikira ne30%, uye zvichemo zvevatengi zvakanyangarika.
Chimwe chinhu chinowanzoonekwa sechinoongororwa ndechekuenzanisa. Granite Surface Plate—ingave yakamira yoga kana kuti yakaiswa—inofanira kugadziriswa nguva nenguva kuti irambe yakavimbika. Mitemo inokurudzira kugadziriswazve kwegore negore kwemaplate ari kushandiswa, kunyange zvazvo ma laboratori ane hungwaru hwepamusoro anogona kuzviita mwedzi mitanhatu yega yega. Kuenzanisa kwechokwadi hakusi chitambi cherabha; kunosanganisira kuyera mazana enzvimbo pamusoro uchishandisa mazinga emagetsi, autocollimators, kana laser interferometers, wobva wagadzira mepu inoratidza kutsauka kubva pakukwirira kusvika kumupata. Ruzivo urwu rwakakosha kuti ISO/IEC 17025 itevedzere mitemo uye igadzirire kuongororwa.
Kugadzirisa zvinhu kunokoshawo. Kunyange zvazvo granite isingade mafuta kana machira akakosha, inofanira kucheneswa nguva nenguva ne isopropyl alcohol kubvisa zvinotonhodza, machipisi esimbi, kana guruva rinogona kupinda muma micro-pores. Usamboisa maturusi anorema zvakananga pamusoro usina mapedhi ekudzivirira, uye dzivisa kudhonza magage blocks—gara uchiasimudza woaisa. Chengeta ndiro yakavharwa kana isiri kushandiswa kudzivirira kusvibiswa nemhepo.
Pakusarudza Granite Surface Plate, tarisa zvinopfuura runako. Simbisa:
- Giredhi re flatness (Giredhi 00 re calibration labs, Giredhi 0 rekuongorora, Giredhi 1 rekushandiswa kwakajairika)
- Chitupa cheASME B89.3.7 kana ISO 8512-2
- Mepu ine ruzivo rwakadzama rwekuti zvinhu zvakati sandara—kwete kungoratidza kuti munhu apasa/akundikana chete
- Kwakatangira uye kunaka kwegranite (zviyo zvakanaka, pasina mitswe kana mitsipa ye quartz)
Uye usambofa wakaderedza chigadziko. Bvunza mutengesi wako kana chakagadzirwa uchishandisa ongororo yechimiro, kana tsoka dzekuyera dzakabatanidzwa, uye kana gungano rese rakaedzwa pasi pemutoro. KuZHHIMG, Granite Surface Plate yega yega ine chigadziko chatinopa inonyorwa seri, yakasimbiswa yega yega, uye inoperekedzwa nechitupa chinoteverwa neNIST. Hatitengesi ma slabs—tinounza masisitimu emetrology.
Nekuti pakupedzisira, kunyatsorongeka hakusi kwekuva nezvishandiso zvinodhura zvakanyanya. Zviri pamusoro pekuva nenheyo yaunogona kuvimba nayo. Ungave uri kuongorora banga re turbine, kuronga pakati pechiumbwa, kana kugadzirisa huwandu hwemageji ekukwirira, data rako rinotanga nepamusoro paro. Kana pamusoro paro pasina kutsetseka, kugadzikana, uye kuteverwa, zvese zvakavakirwa pairi zvinofungidzirwa.
Saka zvibvunze kuti: paunotora chiyero chako chakakosha nhasi, une chivimbo here nereferensi yako—kana kuti unotarisira kuti ichiri yakarurama? KuZHHIMG, tinotenda kuti tariro haisi nzira yekuyera. Tinokubatsira kutsiva kusava nechokwadi nekushanda kwakasimbiswa—nekuti kunyatsojeka kwechokwadi kunotangira kubva pasi zvichikwira.
