Purati yegranite pamusoro ndiyo hwaro hwekuyera mativi. Ndiyo nzvimbo huru yekuyera inoenzaniswa nezvimwe zviyero zvese. Asi haasi mapurati ese epamusoro akagadzirwa akaenzana—uye haasi ese maitiro akafanana. Kana uri kusarudza purati yepamusoro yerabhoritari yemetrology, dhipatimendi rekuongorora, kana nzvimbo yekuenzanisa, kunzwisisa mutsauko uripo pakati pemitemo yeDIN, ASME, neJIS hakusi kungodzidza chete. Musiyano uripo pakati pekutenga purati inosangana nezvaunoda nekutenga isingaenderane nezvaunoda.
Mamiriro Ezvinhu
Mitemo yakati wandei yepasi rose inodzora kururama uye kuyera mapuratifomu epamusoro egranite. Inonyanya kutaurwa nezvayo inosanganisira:
- DIN 876 (chiyero cheGerman), chinofukidza mapurati epamusoro ekuongorora nekuyera
- ASME B89.3.7 (standard yeAmerica), iyo yakatsiva yekare Federal Specification GGG-P-463C
- JIS B 7513 (chiJapan standard), inofukidza mapurati epamusoro kuti iongororwe nemazvo
- GB/T 20428 (muyero wechiChinese)
- BS 817 (Muyero weBritain)
Mwero wega wega unotsanangura mamakisi akasiyana ekururama, nzira dzekuyedza, uye zvinodiwa zvekugamuchira. Plate inosangana neDIN 876 Grade 00 ingasasangana neASME B89.3.7 Grade AA—uye zvinopesana.
Kunzwisisa Magiredhi Ekururama
Kururama kweplate yegranite pamusoro kunowanzo ratidzwa maererano nekushivirira kwayo kusingatsvedzerere pamusoro peplate. Heino kuenzanisa kwakazara:
| Giredhi | Kushivirira Kwakajairika Kwekupfava | Kushandiswa Kwakajairika |
|---|---|---|
| DIN 876 Giredhi 00 | ± 0.001 mm/m | Kuongororwa kwerabhoritari, metrology yakanyatsojeka |
| DIN 876 Giredhi 0 | ± 0.002 mm/m | Kuongorora, kugadzirisa |
| ASME B89.3.7 Giredhi AA | ±(1.0 + L/250) μm | Kuyera kwakanyatsojeka |
| ASME B89.3.7 Giredhi A | ±(2.0 + L/250) μm | Kuongorora kwakawanda |
| Giredhi 0 reJIS | ± 0.003 mm/m | Kuyera nemazvo |
| Giredhi 1 reJIS | ± 0.006 mm/m | Kuongorora musangano |
L = kureba kweplate yakatarisana mu mm
Chinhu chikuru: ndiro ine "Giredhi 00" pasi peDIN haifanirwe kunge yakaenzana ne "Giredhi AA" pasi peASME. Nzira dzekuyedza dzinosiyana, mapoinzi ekuyera anosiyana, uye zvinodiwa zvekugamuchira zvinosiyana.
Zvekutarisa muPlatifomu Yepamusoro Yemhando Yepamusoro
Kupfuura giredhi rekururama, zvinhu zvakawanda zvinosarudza kana plate yepamusoro ichaita sezvainotarisirwa muhupenyu hwayo hwekushanda:
Hunhu Hwakanaka hweChinhu. Granite inofanira kunge yakatsetseka, isina zvikanganiso, uye ine huwandu hwakafanana. Granite yemhando yepasi inogona kunge iine madiki-madiki anotyoka anokanganisa kugadzikana kwenguva refu. PaZHHIMG®, tinoshandisa granite nhema yeZHHIMG® ine huwandu hwe ≈3100 kg/m³—yakakwirira kupfuura granite nhema zhinji dzekuEurope neAmerica—zvichivimbisa kugadzikana kwakanyanya uye kusakara.
Kuomarara uye Kusapfeka. Purati yepamusoro inofanira kuramba kukwenywa uye kusakara kubva pakushandiswa kakawanda. Granite yedu ine kuomarara kweMohs kwe6–7, zvichipa simba rakanaka rekudzivirira kusapfeka kwemakumi emakore ekushandiswa kwezuva nezuva.
Kugadzikana kweThermal. CTE yegranite inofanira kunge yakaderera uye ichifanotaurwa sezvinobvira. Granite yedu nhema yeZHHIMG® inopa kugadzikana kwakanyanya kwekupisa, ichichengetedza kutsetseka pakati pekuchinja kwekupisa izvo zvinogona kukonzera kuti maplate esimbi atenderere.
Kuenzanisa uye Kutevedza. Purati iyi inofanira kuuya nechitupa chekuenzanisa chinotevedza zviyero kubva kusangano renyika remetrology. PaZHHIMG®, purati yega yega yepamusoro inoongororwa uchishandisa zvishandiso zvakapihwa chitupa neJinan Institute of Metrology neShandong Institute of Metrology, pamwe nekutevedza neNational Institute of Metrology of China.
Basa reUnyanzvi Hwekugadzira Zvinhu
Kunyangwe granite yakanakisisa haibatsiri kana isina kupedzwa zvakanaka.ndiro yepamusoro yegraniteZvinosanganisira matanho maviri makuru: kugadzirira kusina chinhu uye kugadzira nemazvo. Nzvimbo isina chinhu inochekwa kubva pabhokisi rakacherwa, yozonyatsogadzirwa kusvika pakuva yakati sandara. Asi danho rekupedzisira—kuwana giredhi rakatarwa rekuva sandara—rinoda hunyanzvi hwekurovera nemaoko.
Nyanzvi dzehunyanzvi dzinonyatsogadzirisa pamusoro peplate kuti iite kuti itsvedzerere uye itsvedzerere. Chidimbu chimwe nechimwe chinofanira kupasa ongororo yakasimba kuti chisimbise kuti chinosangana negiredhi rakatarwa. KuZHHIMG®, magrinder edu makuru ane ruzivo rwemakore anopfuura makumi matatu rwekushandisa maoko, achikwanisa kutsvedza ne micrometer kuburikidza nekubata kwakasimba uko pasina muchina unogona kutevedzera.
Mazano Anoshanda Kune Vatengi
Kana uchienzanisa mashoko kubva kuvagadziri vakasiyana, usavimba nezita rechinhu chacho chete. Chikumbiro:
- Kuwanda chaiko kwegranite (kwete "granite" chete asi mhando chaiyo uye kuwanda kwayo)
- CTE (coefficient of thermal expansion) inoyerwa pa20°C.
- Kushivirira kwakawanikwa kwekutsetseka uye mwero wazvinoyerwa nawo
- Chitupa chekuongorora uye magwaro ekutevera
- Garandi yehupenyu hwebasa uye mutemo wekugadzirisazve
Kana mutengesi asingakwanise kupa ruzivo urwu, izvozvo zvinonyadzisa. Vagadziri vadiki vazhinji vanoshandisa marble yakachipa panzvimbo pegranite chaiyo—tsika yekunyengera yatinopikisa zvikuru. Marble yakapfava, haina kugadzikana, uye inowanzo shandiswa kupfuura granite chaiyo. Musiyano hausi mudiki; musiyano uripo pakati peplate yepamusoro inochengetedza kururama kwayo kwemakumi emakore uye iyo inodonha isina kunyatsojeka mukati memakore.
Kugadzirisa uye Kugadziridzazve Chitupa
Purati yegranite pamusoro haisi mari yekuisa "seta wokanganwa". Kunyangwe mapurati akanakisa anoda kugadziriswa nguva nenguva kuti ave nechokwadi chekuti haana kudonha kubva pakushivirira. ASME B89.3.7 inosanganisira chitupa chitsva, kugadziriswazve mumunda, uye kugadziriswazve mushure mekugadzirwazve. DIN 876 uye JIS B 7513 ane zvinhu zvakafanana.
Kugadzirisa nguva dzose—kuchenesa nezvinhu zvinonyungudutsa zvakakodzera, kudzivirira pamusoro kuti pasarove, uye kushandisa zvivharo zvakakodzera kana zvisiri kushandiswa—kunowedzera hupenyu hweplate yepamusoro zvakanyanya. Uye kana plate ikapera kupfuura zvayakatarwa, kuigadzirisa nenyanzvi inogona kuidzorera pamamiriro ayo matsva.
KuZHHIMG®, hatingogadziri mapuratifomu epamusoro chete. Tinopa rutsigiro rwakakwana rwehupenyu hwese—kubva pakugadzirwa kwekutanga uye kugadziriswa kuburikidza nekuvandudzwa uye kugadziriswazve—nekuti tinonzwisisa kuti mapuratifomu epamusoro haasi chishandiso chete. Ndiwo hwaro hwehurongwa hwako hwese hwekuyera.
