Zomwe ziyenera kuganiziridwa posankha zitsulo zopangira simenti za carbide

Posankha zobowoleza simenti za carbide, zofunikira zolondola pakubowola ziyenera kuganiziridwa poyamba. Nthawi zambiri, kabowo kakang'ono koyenera kukonzedwa, kulolerako kumakhala kochepa. Chifukwa chake, opanga kubowola nthawi zambiri amagawa zobowola molingana ndi kukula kwa dzenje lomwe likupangidwa. Mwa mitundu inayi yomwe ili pamwambayi yobowolera simenti ya carbide, zobowolera zolimba zolimba zolimba zokhala ndi makina olondola kwambiri (zololera za φ10mm zobowoleza zolimba zolimba ndi 0 ~ 0.03mm), ndiye chisankho chabwinoko pakukonza mabowo olondola kwambiri; Kubowola kwa carbide kokhala ndi simenti ndi 0 ~ 0.07mm, komwe kuli koyenera kwambiri pobowola dzenje ndikuwongolera bwino; Kubowola kokhala ndi simenti ya carbide indexable ndikoyenera kumakina olemetsa kwambiri Ngakhale kuti mtengo wake wopangira nthawi zambiri umakhala wotsika kuposa mitundu ina ya kubowola, kuwongolera kwake kumakhalanso kotsika, ndikulolera kwa 0 ~ 0.3mm (kutengera kutalika m'mimba mwake chiŵerengero cha kubowola), choncho nthawi zambiri amagwiritsidwa ntchito pokonza dzenje ndi mwatsatanetsatane otsika, Kapena kumaliza kutsirizitsa dzenje m'malo wotopetsa tsamba.

Kukhazikika kwa kubowola palokha kuyeneranso kuganiziridwa. Mwachitsanzo, zobowola zolimba za carbide zimakhala zolimba kwambiri, kotero zimatha kukwaniritsa makina olondola kwambiri. Chobowola chopangidwa ndi simenti cha carbide chili ndi kusakhazikika kwadongosolo ndipo chitha kupatuka. Zoyika ziwiri zolozera zimayikidwa pabowola iyi. Choyikapo chamkati chimagwiritsidwa ntchito kupangira makina apakati pa dzenje, ndipo choyikapo chakunja chimagwiritsidwa ntchito kusindikiza m'mphepete mwakunja kuchokera pakatikati mpaka m'mimba mwake. Popeza tsamba lamkati lokhalo limalowa mu kudula kumayambiriro kwa kukonzedwa, kubowola kumakhala kosakhazikika, komwe kungapangitse kuti thupi lobowolalo lipatuke, ndipo nthawi yayitali yobowola, imakhala yochuluka kwambiri. Chifukwa chake, mukamagwiritsa ntchito chobowola chopangidwa ndi simenti cha carbide chokhala ndi kutalika kopitilira 4D pakubowola, chakudyacho chiyenera kuchepetsedwa moyenera kumayambiriro kwa gawo lobowola, ndipo kuchuluka kwa chakudya kuyenera kuonjezeredwa mpaka pamlingo wabwinobwino mutalowa mudulidwe lokhazikika. gawo .

Chobowola chopangidwa ndi simenti cha carbide ndi chobowoleracho chosinthika cha simenti cha carbide chimapangidwa ndi m'mphepete mwa symmetrical ndi mtundu wodziyimira pawokha wa geometric. Kukhazikika kwapamwamba kumeneku kumapangitsa kuti zikhale zosafunika pamene kudula mu workpiece Chepetsani mlingo wa chakudya, kupatula pamene kubowola kumayikidwa mosasamala ndikudula pamtunda wina pamwamba pa workpiece. Panthawiyi, tikulimbikitsidwa kuti muchepetse chakudya ndi 30% mpaka 50% pobowola mkati ndi kunja. Chifukwa chitsulo kubowola thupi la mtundu uwu kubowola pang'ono kutulutsa mapindikidwe ang'onoang'ono, ndi oyenera kwambiri lathe processing; pomwe chobowola cholimba cha carbide chimakhala cholimba kwambiri, chimakhala chosavuta kusweka ngati chikugwiritsidwa ntchito pokonza lathe, makamaka ngati kubowola sikunakhazikike bwino. Izi zimakhala choncho makamaka nthawi zina.

Kuchotsa chip ndi vuto lomwe silinganyalanyazidwe pakubowola. M'malo mwake, vuto lomwe limakumana nalo pobowola ndi kusachotsa tchipisi (makamaka popanga zitsulo zokhala ndi mpweya wochepa kwambiri), ndipo vutoli silingapewedwe mosasamala kanthu za mtundu wa kubowola komwe kumagwiritsidwa ntchito. Malo ochitira misonkhano nthawi zambiri amagwiritsa ntchito jakisoni woziziritsa wakunja kuti athandizire kuchotsa chip, koma njira iyi imakhala yothandiza kokha ngati kuya kwa dzenje lopangidwako kuli kochepa kuposa kukula kwa dzenje ndipo magawo odulira achepetsedwa. Kuphatikiza apo, mtundu woyenera wozizirira, kuchuluka kwa mayendedwe ndi kuthamanga ziyenera kusankhidwa kuti zigwirizane ndi kukula kwa kubowola. Pazida zamakina zopanda kuzirala mu spindle, mapaipi ozizira ayenera kugwiritsidwa ntchito. Kuzama kwa dzenje loyenera kukonzedwa, kumakhala kovuta kwambiri kuchotsa tchipisi komanso mphamvu yoziziritsira yomwe ikufunika. Choncho, mpweya wozizira wocheperako womwe wopanga kubowola uyenera kutsimikiziridwa. Ngati kuzizira sikukukwanira, chakudya chopangira makina chiyenera kuchepetsedwa.
