Ena ocheka mphero a ulusi alinso ndi m'mphepete mwake, omwe amatha kukonza nthawi imodzi pobowo. Chidachi chimakhala ndi magwiridwe antchito apamwamba ndipo chimakhala chosinthika kwambiri kuposa kubowola ulusi ndi odula mphero. Kutulutsa kwa ulusi wamkati komwe chida chingathe kukonza ndi D～2D (D ndi mainchesi a thupi locheka).
6 Kupera ulusi wozama kwambiri
Chodulira ulusi wakuya ndi chodulira ulusi wa dzino limodzi. Wodula ulusi wamba ali ndi mano angapo opangira ulusi pamphepete. Malo olumikizana pakati pa chida ndi chogwirira ntchito ndi chachikulu, mphamvu yodulira imakhalanso yayikulu, ndipo m'mimba mwake ya chidacho iyenera kukhala yaying'ono kuposa kabowo ka ulusi pokonza ulusi wamkati. Chifukwa m'mimba mwake thupi la wodulayo lili ndi malire, zomwe zimakhudza kulimba kwa wodulayo, ndipo wodulayo amakakamizika mbali imodzi pamene ulusi wopera, zimakhala zosavuta kusiya chida pamene mphero yakuya, yomwe imakhudza kulondola kwa ulusi. Chifukwa chake, kuya kwabwino kwa odula ulusi wamba kumakhala pafupifupi 2 kuwirikiza kwa thupi la mpeni. Kugwiritsa ntchito mphero zakuya zodula ulusi kumatha kuthana ndi zofooka zomwe zili pamwambapa. Pamene mphamvu yodulira imachepetsedwa, kuya kwa ulusi kumatha kuchulukirachulukira, ndipo kuya kwabwino kwa chida kumatha kufika 3 mpaka 4 kutalika kwa thupi la chida.
7 Ulusi mphero chida dongosolo
Kusinthasintha komanso kuchita bwino ndizotsutsana kwambiri ndi ocheka ulusi. Zida zina zokhala ndi ntchito zophatikizika (monga kubowola ulusi ndi zodula mphero) zimakhala ndi magwiridwe antchito apamwamba koma osasinthasintha, ndipo zida zotha kusinthika nthawi zambiri sizigwira ntchito. Kuti athetse vutoli, ambiri opanga zida apanga makina opangira ulusi wamagetsi. Dongosolo la zida nthawi zambiri limakhala ndi chogwirizira, chotchinga chopingasa komanso chodulira ulusi. Mitundu yosiyanasiyana ya m'mphepete motsutsa-boring chamfering ndi odulira ulusi amatha kusankhidwa malinga ndi zofunikira pakukonza. Dongosolo la chidali lili ndi zinthu zambiri zosunthika komanso magwiridwe antchito apamwamba, koma mtengo wake ndi wokwera kwambiri.
Ntchito ndi mawonekedwe a zida zingapo zomwe zimagwiritsidwa ntchito pogaya ulusi zikufotokozedwa mwachidule pamwambapa. Kuziziritsa ndikofunikanso kwambiri popera ulusi. Ndikofunikira kugwiritsa ntchito zida zamakina ndi zida zoziziritsa mkati. Chifukwa chida chikazungulira pa liwiro lalikulu, choziziritsa chakunja sichosavuta kulowa pansi pa mphamvu ya centrifugal. Kuphatikiza pa njira yozizirira yamkati, yomwe imatha kuziziritsa chidacho bwino, ndikofunikira kwambiri kuti choziziritsa kukhosi kwambiri chingathandize kuchotsa chip pokonza ulusi wa bowo lakhungu. Makamaka, apamwamba mkati kuzirala kuthamanga chofunika pamene Machining yaing'ono m'mimba mwake mkati ulusi mabowo. Onetsetsani kuti chip chisamuke bwino. Komanso, posankha ulusi mphero chida, zofunikira processing ayenera kuganiziridwa mozama, monga kupanga mtanda, chiwerengero cha mabowo wononga, workpiece chuma, ulusi kulondola, specifications kukula ndi zinthu zina zambiri, ndi chida ayenera kusankhidwa mwanzeru.
