I. Kugadzira Maitiro eGranite Straightedge
Raw material screening nekucheka
Maitiro ekusarudza zvinhu: Yepamusoro-mhando giraniti ine density ye ≥2.7g/cm³ uye mwero wekutora mvura we <0.1% (senge "Jinan Green" kubva kuShandong uye "Black Gold Sand" kubva kuIndia) inofanira kusarudzwa. Iyo mineral particles inofanira kuva yunifomu (quartz particles ≤2mm), isina kuputika uye pores, uye matombo akavanzika akavanzika anofanira kubviswa kuburikidza ne-X-ray kukanganisa kukanganisa.
Kucheka kwakashata: Shandisa dhaimondi denderedzwa saha kucheka isina chinhu kuita isina chinhu yakakura 5-10mm kupfuura saizi yechigadzirwa chakapedzwa. Iko kukanganisa kwekufuratira kwekucheka kwepamusoro kunofanirwa kudzorwa mukati me ± 0.5mm.
2. Kurapa kuchembera
Kuchembera kwepanyama: Isa muviri wakasvibira mumhepo yakavhurika kwemwedzi mitanhatu kusvika gumi nemiviri. Kuburikidza nemusiyano wetembiricha pakati pemasikati nehusiku uye shanduko yehunyoro, pamusoro pe90% yekushushikana kwemukati inoburitswa kudzivirira deformation mune inotevera nhanho.
Artificial kuchembera (optional) : Vamwe vagadziri vanoshandisa tembiricha yevira (100-150 ℃) kwemaawa makumi maviri nemana kuti ikurumidze kuburitsa kushushikana, iyo inokodzera kuraira kwekukurumidzira, asi mhedzisiro yacho yakadzikira zvishoma pane yekuchembera kwechisikigo.
3. Kukuya kwakakasharara nekutarisa pamusoro pekugadzirisa
Kukuya kwakashata uye kuumbwa: Shandisa 200-400 mesh diamond grinding vhiri kukuya isina chinhu, bvisa mitsara yekucheka, gadzirisa flatness kubva ± 0.5mm kusvika ± 0.1mm/m (100μm/m), uye sarudza nzvimbo yekutarisa.
Kusashanda kwepamusoro kurapwa: Chamfer kana kupfekedza padivi nepazasi pendi (sekupfapfaidza pendi inorwisa ngura) kudzivirira kumucheto kutsemuka uye kuwedzera mwando.
4. Kugaya chaiko (core process)
Iko kusvetuka chaiko kunowanikwa kuburikidza nehierarchical kugaya, iyo yakakamurwa kuita matanho matatu:
Kukuya kwakashata: Shandisa 400-800 mesh abrasives (silicon carbide kana diamond micro-powder) pamwe chete negranite yekukuya chikuva kugadzirisa flatness kusvika ± 10μm/m, uye pamusoro roughness Ra≤0.8μm.
Kunyatso kugaya: Nekuchinja kune 1200-2000 mesh abrasives uye kusanganisa nemagetsi level (kunyatso ± 1μm / m) yekutarisa-nguva chaiyo, flatness yakagadziridzwa kusvika ± 3μm / m, uye roughness Ra iri ≤0.4μm.
Ultra-fine grinding (kiyi kune yakakwirira-chaiyo zvigadzirwa) : Nekushandisa W10-W5 giredhi diki-upfu (particle size 5-10μm) uye kemikari polishing fluid, kuburikidza neaviri chiito che "mechanical grinding + chemical corrosion", iyo yekupedzisira flatness inogona kusvika ± 1μm/m, uye pamusoro roughness Ra≤0.2μm.
5. Kunyatsoona uye kugadzirisa
Zvishandiso zvekuona: Laser interferometer (kunyatso ± 0.1μm) uye nhanho yemagetsi (resolution 0.001mm/m) inoshandiswa kuita yakazara-renji yekuonekwa kwe flatness uye kutwasanuka, uye kudhirowa mepu yekuparadzira kukanganisa.
Yakavharwa-loop kururamisa: Kubva pane yekuona data, yemuno yekuwedzera kugaya inoitwa panzvimbo yakakwirira-yekukanganisa kuburikidza nemuchina weCNC grinding kusvikira iyo yakazara-yakazara kukanganisa ichidzorwa mukati mechinangwa.
6. Kudzivirira kwepamusoro uye kurongedza
Dziviriro yekurapa: Pfapfaidza nano-scale silica coating (5-10μm gobvu) panzvimbo yereferensi, uye isa anti-corrosion wax layer pane isiri-kushanda kuti udzivise kunyura kana kuti oxidation panguva yekushandiswa kwenguva refu.
Precision kurongedza: Iyo yakazara mune shockproof makesi emapuranga ane desiccants. Panguva yekufambisa, mutsauko wetembiricha unodzorwa mukati me ± 5 ℃ kudzivirira iko kunyungudika kunokonzerwa nekudengenyeka.
Ii. Yepamusoro Precision Giredhi uye Indasitiri Maitiro
Iko kurongeka kwegranite kutwasanuka kunobva pane chikanganiso cheflatness seyepakati index. Zvinoenderana neyakajairwa chiyero chenyika (GB/T 4977-2018) uye chiyero chepasi rose (ISO 2768-2), magiredhi ayo echokwadi uye maparamendi anoenderana anotevera:
Marabhoritari epamusoro anogona kuwana kurongeka kwekupedzisira:
Kuburikidza nenano-scale grinding techniques (senge magneorheological polishing uye ion beam modification), kupfava kwezvimwe zvigadzirwa zvepamusoro-soro zvinogona kuputswa kusvika ± 0.5μm/m (kureva kuti, kukanganisa kwemamita kureba hakupfuuri 0.5 micrometers), kusvika kune imwe nzvimbo yekutarisa ndege. Iwo anonyanya kushandiswa mune zvakanyatsojeka mamiriro akadai seaerospace uye metrology masangano.
Iii. Kuenzanisa Kwezvinhu Zvinokanganisa Kururama
Pfupiso: Iyo chaiyo chaiyo yegranite straightedge inotsamira pane yakazara-maitiro kudzora kwe "yemhando yepamusoro zvinhu + zvekupedzisira-kuchembera + graded kugaya + hutsinye nharaunda", pakati peiyo nzira yekukuya ndiyo musimboti wekubudirira mune chaiyo. Nekuvandudzwa kwenanofabrication tekinoroji, iko kurongeka kwayo kuri kufambira mberi zvishoma nezvishoma yakananga ku-sub-micron nhanho uye yave isingadzokerike bhenji rekushandisa mumunda wepamusoro-kuguma kugadzira.
