Kodi njira zabwino kwambiri zogwiritsira ntchito makina ndi kukonza mapepala a granite pamwamba ndi ziti?

Buku Lotsogolera pa Kukonza ndi Kukonza Mapepala a Granite: Mapepala a granite olondola kwambiri amafunika makina apadera komanso kukonzedwa kuti atsimikizire kuti ndi olondola komanso amoyo. Asanapukutidwe, gawo la granite liyenera kukonzedwa koyamba ndi makina opingasa kutengera mfundo zoyikiramo zitatu. Pambuyo popukutidwa mopingasa, ngati makina a CNC sangathe kukwaniritsa kulondola kofunikira—nthawi zambiri kufika pa kulondola kwa Giredi 0 (kulekerera kwa 0.01mm/m monga momwe zafotokozedwera mu DIN 876)—kumaliza ndi manja kumakhala kofunikira kuti mupeze magiredi apamwamba olondola monga Giredi 00 (kulekerera kwa 0.005mm/m malinga ndi miyezo ya ASTM B89.3.7).

Njira yopangira makina imaphatikizapo masitepe angapo ofunikira. Choyamba, kupukusa mopanda mphamvu kumakhazikitsa kusalala koyambira, kutsatiridwa ndi kutsiriza kwachiwiri kuti muchotse zizindikiro za makina. Kupukusa molondola, komwe kumachitika nthawi zambiri pamanja, kumakonza pamwamba kuti pakhale kulekerera kosalala komwe kumafunidwa komanso kusalala kwa pamwamba (Ra value ya 0.32-0.63μm, pomwe Ra ikuyimira kusiyana kwapakati pa mbiri ya pamwamba). Pomaliza, kuwunika mosamala kumatsimikizira kuti kutsata miyezo yaukadaulo, ndi malo oyezera omwe amayikidwa mwanzeru kudutsa ma diagonal, m'mphepete, ndi pakati - nthawi zambiri mfundo 10-50 kutengera kukula kwa mbale - kuti zitsimikizire kuwunika kolondola kofanana.

Kugwira ndi kuyika kumakhudza kwambiri kulondola. Chifukwa cha kulimba kwa granite (kulimba kwa Mohs 6-7), kukweza molakwika kungayambitse kusintha kosatha. Pa ntchito zofunika kwambiri zomwe zimafuna kulondola kwa Giredi 00, kuyika manja pambuyo poyika ndikofunikira kuti kubwezeretse kulondola komwe kwawonongeka panthawi yoyendera. Kusamala kumeneku kumasiyanitsa mbale zapamwamba za granite zolondola kwambiri ndi mitundu yokhazikika yopangidwa ndi makina.

Machitidwe osamalira amakhudza mwachindunji magwiridwe antchito ndi moyo wa munthu. Yambani ndi kuyeretsa bwino pogwiritsa ntchito zotsukira za pH zosalowerera ndale—pewani zinthu zokhala ndi asidi zomwe zimatha kuswa pamwamba. Kuyesa kwa pachaka pogwiritsa ntchito ma laser interferometers, omwe amatsatiridwa ndi miyezo ya NIST, kumatsimikizira kuti zinthuzo zikuyenda bwino. Mukayika zinthu zogwirira ntchito, lolani kuti kutentha kufanane (nthawi zambiri mphindi 15-30) kuti mupewe zolakwika zoyezera kuchokera ku kusiyana kwa kutentha. Musamayendetse zinthu zokwawa pamwamba, chifukwa izi zingayambitse kukanda pang'ono komwe kumakhudza kusalala.

Malangizo oyenera ogwiritsira ntchito akuphatikizapo kulemekeza malire a katundu kuti apewe kusintha kwa kapangidwe kake, kusunga malo okhazikika (kutentha 20±2°C, chinyezi 50±5%), ndikugwiritsa ntchito zida zonyamulira zapadera kuti mupewe kuwonongeka kwa ndege. Mosiyana ndi zitsulo zina, kukhazikika kwa kutentha kwa granite (0.01ppm/°C) kumachepetsa kukhudzidwa kwa chilengedwe, koma kusintha kwadzidzidzi kwa kutentha kuyenera kupewedwabe.

Monga chida choyambira pa kuwerengera molondola, ma granite surface plates ovomerezeka (ovomerezedwa ndi ISO 17025) amagwira ntchito ngati muyezo wofotokozera miyeso ya miyeso. Kusamalira kwawo kumafuna khama lochepa—kungopukuta ndi nsalu yopanda ulusi mukatha kugwiritsa ntchito—sikufunikira zophimba zapadera kapena mafuta. Potsatira njira izi zopangira ndi kusamalira, ma granite surface plates olondola amapereka magwiridwe antchito odalirika kwa zaka zambiri, zomwe zimapangitsa kuti akhale ofunikira kwambiri m'ma laboratories owerengera, kupanga ndege, komanso ntchito zaukadaulo zolondola kwambiri.
