Kutendeseka kwechero chaiyo kugadzira kana metrology maitiro anotanga nehwaro hwayo. PaZHHIMG®, nepo mukurumbira wedu wakavakirwa pa Ultra-Precision Granite mhinduro, tinoona basa rakakosha rinoitwa neCast Iron Surface Plates uye Makona Plate mumaindasitiri epasi rose. Kunzwisisa nzira yekuisa zvakanaka, kuchengetedza, uye kuona chokwadi chezvishandiso zvekushandisa izvi hakusi kungoitwa kwakanakisa-ndiwo mutsauko pakati pekusimbiswa kwemhando uye zvimedu zvinodhura.
Iyo Absolute Prerequisite: Kuiswa Kwakakodzera uye Kusagadzikana Chimiro
Pamberi pesimbi yakakandwa yekumaka ndiro inogona kuunza kwayo kurongeka kwayo, inofanirwa kuiswa nemazvo uye kugadziridzwa. Ichi chakakosha kuseta chikamu hachisi chemaitiro chete; iyo inokanganisa zvakananga kurongeka kweplate uye flatness. Kuisa zvisina kufanira-sekugovera kusaenzana kwemutoro kana kusaenzana kwakashata-kunogona kutyora mirau yeindasitiri uye kukanganisa zvachose ndiro, zvichiita kuti isashande. Nokudaro, vashandi vane mvumo chete, vakadzidziswa vanofanira kuita basa iri. Kutyora maitirwo aya hakungoite chete asi kunogona kukanganisa chimiro cheiyo chaiyo chishandiso.
Kumaka Plate muKufambiswa Kwebasa: Iyo Reference Datum
Mune chero wekishopu, maturusi akarongedzerwa kune chaiwo mabasa: referensi, kuyera, kudhirowa kwakananga, uye kusungirira. Chiratidzo chekumaka ndicho chinhu chakakosha chekushandisa pakunyora. Kunyora pachezvako ndiko kwakakosha kushandura dhizaini pane isina chinhu kana semi-yakapedzwa workpiece, kumisikidza yakajeka miganho yekugadzira, mareferenzi, uye yakakosha mitsetse yekururamisa. Uku kwekutanga kunyora chaiko, kunowanzo kudiwa kuve mukati me 0.25 mm kusvika 0.5mm, kune yakananga uye yakadzama kukanganisa pamhando yechigadzirwa chekupedzisira.
Kuti uchengetedze kutendeseka uku, ndiro yacho inofanira kuenzaniswa uye kuiswa zvakachengeteka, nemutoro wakagoverwa zvakaenzana kumativi ose ekutsigira kudzivirira kushushikana kwemaitiro. Vashandisi vanofanirwa kuve nechokwadi chekuti uremu hwebasa haumbopfuure chiyero cheplate kudzivirira kukuvadzwa kwechimiro, deformation, uye kudzikiswa kwemhando yebasa. Uyezve, nzvimbo yekushanda inofanirwa kushandiswa zvakafanana kudzivirira kusapfeka kwenzvimbo uye denti, kuve nechokwadi chekugara kwenguva refu.
Kuongorora Flatness: Iyo Sayenzi Yekusimbisa
Chiyero chechokwadi cheplate yekunyora ndiyo flatness yekushanda kwayo. Nzira yekutanga yekusimbisa iSpot Method. Iyi nzira inoraira density inodiwa yenzvimbo dzekusangana mukati me25mm square nharaunda:
- Giredhi 0 uye 1 Plates: Madiki 25 mavara.
- Giredhi 2 Plates: Maminimuminimu makumi maviri mavara.
- Giredhi 3 Plates: Maminimuminimu gumi nemaviri mavara.
Nepo hunyanzvi hwechinyakare hwe "kukwenya mahwendefa maviri kune mumwe nemumwe" huchigona kuita kuti pave nekubatana kwakasimba uye kushamwaridzana kwepamusoro, hazvivimbise kupfava. Iyi tekinoroji inogona kuita kuti pave nenzvimbo mbiri dzakanyatso kubatirana idzo, chokwadi, dzakakombama. Chokwadi kutwasanuka uye kupfava kunofanirwa kusimbiswa uchishandisa nzira dzakaomarara. Kutsveyama kutsauswa kunogona kuverengerwa nekufambisa chiratidzo chedhiya uye chitsigiro chayo chinomira padivi penzvimbo inozivikanwa yakatwasuka, senge chaiyo-yekona yekurudyi mutongi, pakatarisana neplate. Kune mahwendefa ekuyeresa anodiwa zvakanyanya, iyo Optical Plane Method inoshandisa optical interferometry inoshandiswa kuratidza huchokwadi padanho resub-micron.
Kukanganisa Kubata: Kuvimbisa Hurefu Hwehupenyu uye Kutevedza
Kumaka plate mhando inotongwa neakasimba ekudzora masisitimu, senge JB/T 7974-2000 yakajairwa muindasitiri yemuchina. Munguva yekukanda maitiro, kukanganisa senge porosity, maburi ejecha, uye shrinkage cavities zvinogona kuitika. Mabatirwo akafanira ezvakaremara zvekukandira izvi kwakakosha paupenyu hwesevhisi yendiro. Kune mahwendefa ane giredhi rechokwadi pasi pe "00," kumwe kugadzirisa kunobvumidzwa:
- Zvirema zvidiki (zvimedu zvejecha zvine dhayamita isingasviki 15mm) zvinogona kubatirwa nezvinhu zvakafanana, chero kuoma kweplug kwakadzikira pane simbi yakatenderedza.
- Nzvimbo yekushanda haifanire kunge iine mapoinzi anodarika mana, akapatsanurwa nechinhambwe chingangoita $80\text{mm}$.
Kupfuura kukanganisa kwekukanda, nzvimbo yekushanda inofanirwa kunge isina chero kushandisa-inokanganisa ngura, mavanga, kana mazino.
Kuchengetedza Kutsungirira Kwakarurama
Kunyangwe chishandiso chereferensi iCast Iron Marking Plate kana ZHHIMG® Granite Surface Plate, kugadzirisa kuri nyore asi kwakakosha. Nzvimbo yacho inofanira kuchengetedzwa yakachena; kana isiri kushandiswa, inofanira kunyatsocheneswa uye yakaputirwa nemafuta ekudzivirira kudzivirira ngura uye yakavharwa nevhavha yekudzivirira. Kushandisa kunofanirwa kugara kuchiitwa munzvimbo inodzorwa, zvakanaka pane ambient tembiricha ye (20± 5) ℃, uye kudedera kunofanirwa kudzivirirwa. Nekuomerera kune idzi nhungamiro dzakasimba dzekuisa, kushandiswa, uye kugadzirisa, vagadziri vanogona kuona kuti ndege dzavo dzereferenzi dzinoramba dzakarurama, dzichidzivirira kunaka uye kuvimbika kwezvigadzirwa zvavo zvekupedzisira.
