Mawu Ofunika: Makina ophulitsira mchenga a Junda ophulitsira mchenga
Makina ophulitsira mchenga omwe akugwiritsidwa ntchito, ayenera kumvetsetsa momwe amagwirira ntchito, kuti achepetse kulephera kwa zida, alimbikitse kugwiritsa ntchito bwino zida, komanso kuti ogwiritsa ntchito ambiri amvetsetse momwe amagwiritsira ntchito, njira yotsatira yatsatanetsatane imayamba.
Choyamba, chithandizo chisanachitike.
Makina opukutira mchenga a workpiece omwe ali mu kupopera, kupopera zoteteza (utoto kapena zinthu zina zotsutsana ndi kuwononga), pamwamba pa workpieceyo payenera kukonzedwa bwino, komwe kumadziwika kuti pretreatment.
Ubwino wa chithandizo chisanadze umakhudza kumatirira, mawonekedwe, kukana chinyezi komanso kukana dzimbiri kwa chophimbacho, chifukwa filimu yabwino yophimba (yosanjikiza) imamatiridwa pamwamba pomwe yatsukidwa mosamala. Ngati ntchito yokonzekera siili bwino, dzimbiri lidzapitirira kufalikira pansi pa chophimbacho ndikuchotsa ming'alu yophimba. Pambuyo poyeretsa bwino pamwamba pake ndi kuyeretsa kosavuta (kwa sandpaper kapena burashi yamanja) kwa chidutswa chogwirira ntchito, ndi njira yowonetsera poyerekeza chophimbacho, moyo ukhoza kukhala nthawi 4-5. Pali njira zambiri zoyeretsera pamwamba, koma njira yovomerezeka kwambiri ndi: A. kuyeretsa zosungunulira zida za BC m'manja D. zida zamagetsi
Mwanjira izi, njira iliyonse ili ndi momwe imagwiritsidwira ntchito, koma mu njira zonse zotsukira pamwamba, njira yophulitsira mchenga ndi yolondola kwambiri, yotsika, yodziwika bwino, komanso yotakata, chifukwa chake ndi:
A, kupukuta mchenga ndi bwino kuposa njira zina zotsukira pamwamba pa chinthu chogwirira ntchito.
B, Palibe njira ina yomwe imakulolani kusankha pakati pa magawo anayi a ukhondo omwe amadziwika bwino komanso ovomerezeka.
Chachiwiri, kuphulika kwa mchenga.
Makina opopera mchenga amagwiritsa ntchito mpweya wopanikizika ngati mphamvu kuti apange mtanda wothira mwachangu, zinthu zopopera (mkuwa, mchenga wa quartz, mchenga wachitsulo, mchenga wa m'nyanja, silicon carbide, ndi zina zotero), monga ndege yothamanga kwambiri yomwe imafunika kuthana ndi pamwamba, mawonekedwe a pamwamba amasintha, chifukwa cha mphamvu yowononga pamwamba pa workpiece ndi kudula, kupanga ukhondo ndi kuuma kosiyanasiyana kwa workpiece pamwamba, kupanga pamwamba pa makina. Zingathe kukonzedwa, kotero onjezerani kutopa kwa workpiece, onjezerani kugwirizana pakati pake ndi chophimba, onjezerani kulimba kwa filimuyo, komanso kumathandiza kuti utoto ndi zokongoletsera ziyende bwino.
