Chifukwa Chake Chitsulo Chopangidwa Chikulamulirabe M'malo Opanga Zenizeni
Zaka zingapo zilizonse, munthu wina mumakampani amafalitsa nkhani yokhudza momwe granite imasinthira chitsulo chopangidwa kuti chigwiritsidwe ntchito poyeza molondola. Ndipo zaka zingapo zilizonse, akatswiri odziwa bwino ntchito zamakina amawerenga nkhanizo, amagwedeza mutu mwaulemu, ndikupitiliza kugwiritsa ntchito mbale zawo zachitsulo chopangidwa.
Chifukwa chake si kuuma mtima, koma ndi sayansi ya fizikisi ndi kuchita zinthu moyenera.
Chitsulo chopangidwa ndi chitsulo chili ndi mphamvu yapadera yochepetsera chinyezi kuposa granite. Pamene ntchito zodula kwambiri zikuchitika pafupi — kugaya, kugaya, EDM — mphamvu yogwedera yomwe ingawonetse pamwamba pa granite yolimba ndikuipitsa miyeso yapafupi imatengedwa ndi kapangidwe ka chitsulo chopangidwa ndi chitsulocho. Si matsenga. Ndi ma graphite flakes omwe ali mu matrix ya chitsulo chopangidwa ndi chitsulo akuchita zomwe adapangidwira kuchita.
Khalidwe lochepetsa kutentha kumeneku ndi lofunika kwambiri m'malo opangira zinthu kuposa m'malo oyezera kutentha omwe amayendetsedwa ndi nyengo. Ndipo m'malo opangira zinthu ndi komwe kupanga zinthu molondola kwambiri padziko lonse lapansi kumachitika.
Chitsulo chopangidwa ndi chitsulo chimakonzedwanso m'njira zomwe granite singathe kukonzedwa. Ngati mbale ya pamwamba yachitsulo chopangidwa ndi chitsulo yawonongeka mosagwirizana, kapena ikawonongeka pamalo enaake, katswiri wamakina amatha kuikonzanso - kuibwezeretsa ku Giredi 00 popanda kusintha mbale yonse. Izi zimawonjezera moyo wa mbale ya pamwamba yachitsulo chopangidwa bwino mpaka zaka 30, 40, kapena 50. Yesani kuchotsa zimenezo mu mbale ya granite yomwe yagwetsedwa.
Masewera a Giredi: Kodi Manambala Amatanthauza Chiyani Kwenikweni?
Wogulitsa akakupatsani chizindikiro cha mbale yachitsulo chopangidwa ndi chitsulo, nthawi zambiri amatchula giredi - nthawi zambiri Giredi 00, Giredi 0, Giredi 1, kapena Giredi 2. Magiredi awa amafotokozedwa mu miyezo monga DIN 876, ASME GGGP-463C, ISO 8512, ndi ena. Kumvetsetsa tanthauzo lawo ndikofunikira kwambiri pogula mbale yoyenera.
Giredi imafotokoza kulekerera kwa flatness — kusiyana kwakukulu kovomerezeka kuchokera ku malo ofotokozera angwiro omwe ali pamwamba ponse poyezera.
Kwa DIN 876, kulekerera kumawoneka motere:
Giredi 00: pafupifupi ma microns 2.3 kusiyana pa 1,000mm. Giredi 0: pafupifupi ma microns 4.6. Giredi 1: pafupifupi ma microns 9.2. Giredi 2: pafupifupi ma microns 18.5.
Kutsika kulikonse mu giredi kumawonjezera kawiri cholakwika chovomerezeka. Pa ntchito zomwe zimafuna kulondola kwa mulingo wa micron, izi ndizofunikira kwambiri. Mbale yomwe imalola ma micron 18.5 a flatness deviation — Giredi 2 — imadya pafupifupi gulu lanu lonse la tolerance band musanayambe kuyeza.
Ntchito zambiri zowunikira mafakitale zimatchula Giredi 0 kapena Giredi 1. Giredi 00 imasungidwa ku ma lab a metrology, kuwunika komaliza kwa ndege, ndi ntchito zomwe bajeti yoyesa ndi yochepa. Kusiyana kwa mitengo pakati pa ma giredi kumasonyeza nthawi yowonjezera ndi luso lofunikira popanga zinthu, osati kusiyana kwa malonda kokha.
