Mawonekedwe a Milling Cutters
Kuyesera kulimbitsa kukhazikika kwazomwe zimapangidwira zisanayambe kukonza kudzabweretsa phindu pakupanga kwanthawi yayitali m'tsogolomu. Izo osati kutalikitsa moyo wa chida, komanso bwino pamwamba pa workpiece ndi kuchepetsa Machining cholakwika.
Momwemonso, kusankha kogwiritsa ntchito molakwika kudzafupikitsa moyo wa chida. Mwachitsanzo, ngati mphero yokhala ndi mainchesi a 3.175mm yayikidwa mu chodulira (m'malo mwa chuck ya kasupe), chifukwa cha zomangira zomangira, kusiyana koyenera pakati pa chodula ndi chodulira kumakondera kumodzi. mbali, ndipo pakati pa wodulayo amapatuka. Pakatikati pa kuzungulira kwa chogwiritsira ntchito kumawonjezera kutuluka kwa radial kwa chodula mphero panthawi yogwira ntchito, zomwe zimapangitsa kuti pakhale kudulidwa kosawerengeka pa dzino lililonse la wodula mphero. Kudula kumeneku sikwabwino kwa chida, makamaka pogaya ma aloyi opangidwa ndi faifi tambala.
Pogwiritsa ntchito chida chomwe chimapangitsa kuti pakhale kukhazikika kwa zida zoyika zida, monga hydraulic chuck ndi shrink-fit chuck, kudula kumatha kukhala koyenera komanso kokhazikika, kuvala kwa zida kumachepetsedwa, ndipo mawonekedwe apamwamba amawongolera. Mfundo iyenera kutsatiridwa posankha chogwirira, ndiko kuti, chogwiriracho chiyenera kukhala chachifupi momwe mungathere. Zida izi ndi zida zomangira zogwirira ntchito zimagwiranso ntchito pogaya zinthu zilizonse, ndipo pogaya ma aloyi opangidwa ndi faifi tambala, luso laukadaulo laukadaulo limafunikira ngati kuli kotheka.
Kugwiritsa Ntchito Zida
Mosasamala kanthu za momwe chidacho chimapangidwira, kapena kuti chimapangidwa ndi chiyani, wopanga zida ayenera kupereka zikhalidwe zoyambira pakudula liwiro ndi chakudya pa dzino. Ngati izi sizikupezeka, dipatimenti yaukadaulo ya wopanga iyenera kufunsidwa. Opanga akuyenera kudziwa momwe zopangira zawo zimakwaniritsira m'lifupi, kuzungulira, kugwetsa, kapena kudumphadumpha, popeza ambiri mwa odula mphero sangathe kugwira ntchito zambiri izi. Mwachitsanzo, ngati chodulira mphero sichikhala ndi ngodya yayikulu yokwanira yachiwiri, ngodya ya bevel yodumphadumpha imachepetsedwa.
Mwachiwonekere, ngati mphamvu yopangira chida yadutsa, idzawononga chidacho. N'chimodzimodzinso ndi mphero. Ngati tchipisi sitingathe kuthamangitsidwa pansi pa groove mu nthawi, tchipisi tidzafinyidwa ndipo chida chidzawonongeka pambuyo pake. Pomaliza, izi zimawononga moyo wa zida pogaya ma superalloy. Ngati mukuganiza kuti kuchepetsa kuchuluka kwa chakudya kumawonjezera moyo wa zida, zidapezeka kuti ndizolakwika. Chitsanzo chodziwika bwino ndi pamene kudula koyamba kumapangidwa ndipo zinthu zimawoneka zolimba kwambiri. Ngati chakudya chachepetsedwa (mwachitsanzo, chakudya pa dzino la chodulira mphero chimachepetsedwa kukhala 0.025 mpaka 0.5 mm), m'mphepete mwa chidacho chidzapukuta mwamphamvu chogwiritsira ntchito, ndipo zotsatira zake zidzakhala kuti chidacho chidzawonongeka. mwachangu kapena nthawi yomweyo. Kukangana kungayambitse kuuma kwa ntchito pamwamba pa workpiece. Pofuna kupewa kuuma kwa ntchito, katundu wina wodula (0.15-0.2mm / chakudya pa dzino) ayenera kusamalidwa podula mpeni woyamba.
