Kodi plunge milling ndi chiyani?Kodi ntchito pokonza ndi chiyani?

▉Ubwino

Plunge milling ili ndi zabwino izi:

① Itha kuchepetsa kusinthika kwa workpiece;

②Itha kuchepetsa mphamvu yodulira yozungulira yomwe imagwira ntchito pamakina amphero, zomwe zikutanthauza kuti spindle yokhala ndi shafting yotopa imatha kugwiritsidwabe ntchito poponya mphero popanda kukhudza luso la makina opangira;

③The overhang of the tool is large, which is a phindu kwambiri mphero ya workpiece grooves kapena pamwamba;

④ Imatha kuzindikira kuphulika kwa zida za alloy zotentha kwambiri (monga Inconel).Plunge mphero ndi yabwino popanga nkhungu zomangika ndipo ndi bwino kumakanika zinthu zakuthambo.Kugwiritsidwa ntchito kumodzi ndikudumphira kwa masamba a turbine pamakina atatu kapena anayi amphero, omwe nthawi zambiri amafunikira zida zapadera zamakina.

▉Mfundo yogwira ntchito

Mukagwetsera tsamba la turbine, limatha kupukutidwa kuchokera pamwamba pa chogwirira ntchito mpaka ku mizu ya chogwiriracho, ndipo ma geometries ovuta kwambiri amatha kupangidwa mwa kumasulira kosavuta kwa ndege ya XY.Pamene kudumphira kumachitidwa, m'mphepete mwa mphero wodula amapangidwa podutsana ndi mbiri ya zoyikapo.Kuzama kwakuya kumatha kufika 250mm popanda kuyankhulana kapena kupotoza.Mayendedwe odulira a chida chokhudzana ndi workpiece akhoza kukhala pansi kapena pansi.Kukwera, koma nthawi zambiri kutsika pansi kumakhala kofala kwambiri.Pogwetsa ndege yopendekera, wodulayo amasuntha mozungulira pa Z-axis ndi X-axis.Nthawi zina pokonza, odula mphero ozungulira, odula kumaso kapena ocheka mphero amathanso kugwiritsidwa ntchito pokonza zosiyanasiyana monga mphero, mphero, ma bevel, ndi mphero.

▉Kuchuluka kwa ntchito

Odulira odzipatulira odzipatulira amagwiritsidwa ntchito popangira roughing kapena kumaliza pang'ono, kudula m'mphepete kapena kudula m'mphepete mwa chogwirira ntchito, komanso ma geometri ovuta, kuphatikiza kukumba mizu.Kuonetsetsa kutentha kosalekeza, zodulira shank plunging zimaziziritsidwa mkati.Thupi lodula ndi kuyika kwa chodulira chodulira amapangidwa kutiiwoakhoza kudula mu workpiece pa ngodya yabwino.Nthawi zambiri, mbali yodula ya wodulayo ndi 87 ° kapena 90 °, ndipo kuchuluka kwa chakudya kumayambira 0.08 mpaka 0.25mm / dzino.Kuchuluka kwa zoyikapo zomwe ziyenera kumangika pa chodula chilichonse zimatengera kukula kwa chodulira.Mwachitsanzo, chodulira mphero chokhala ndi mainchesi a φ20mm chikhoza kuikidwa ndi 2 zoyikapo, pomwe chodulira mphero chokhala ndi mainchesi a f125mm chikhoza kuyikidwa ndi 8.Kuti mudziwe ngati makina opangira makinawa ndi oyenera kugwetsa mphero, zofunikira za makina opangira makinawo ziyenera kuganiziridwa.Ngati ntchito yopangira makina imafuna kuchuluka kwachitsulo chochotsa zitsulo, kugwiritsa ntchito mphero kungathe kuchepetsa nthawi yopangira makina.

Nthawi ina yoyenera njira yodumphira ndi pamene ntchito yopangira makina imafuna kutalika kwakukulu kwa axial kwa chida (monga mphero zazikulu kapena mitsinje yakuya), popeza njira yodulira imatha kuchepetsa mphamvu yodulira ma radial, imayerekezedwa ndi mphero. njira, ali apamwamba Machining bata.Kuonjezera apo, pamene mbali za workpiece zomwe zimayenera kudulidwa zimakhala zovuta kuzifikitsa ndi njira zowonongeka, mphero yothira ingathenso kuganiziridwa.Popeza chodulira chimatha kudula zitsulo m'mwamba, ma geometries ovuta amatha kupedwa.

Kuchokera pakuwona kugwiritsa ntchito chida cha makina, ngati mphamvu ya makina opangira ntchito yogwiritsidwa ntchito ndi yochepa, njira yopangira mphero imatha kuganiziridwa, chifukwa mphamvu yofunikira pa mphero ndi yocheperapo kuposa ya mphero ya helical, kotero ndizotheka kugwiritsa ntchito. zida zamakina zakale kapena zida zamakina opanda mphamvu kuti mupeze ntchito yabwino.High processing dzuwa.Mwachitsanzo, kugwetsa ma grooves akuya kumatha kutheka pa chida cha kalasi 40, chomwe sichiyenera kupanga makina odulira atali atali, chifukwa mphamvu yodulira yozungulira yomwe imapangidwa ndi mphero ya helical ndi yayikulu, yomwe ndi yosavuta kupanga mphero. kugwedezeka kwa cutter.

Plunge mphero ndi yabwino pamakina akale okhala ndi zotchingira zong'ambika chifukwa cha mphamvu zochepa zodulira ma radial panthawi yolowera.Njira yopangira mphero imagwiritsidwa ntchito makamaka pakupanga makina ovuta kapena omaliza, ndipo kupatuka pang'ono kwa axial komwe kumachitika chifukwa cha kuvala kwa shaft system sikungakhudze kwambiri makinawo.Monga mtundu watsopano wa CNC Machining njira,ndinjira ya plunge mphero imayika zofunikira zatsopano zamapulogalamu a makina a CNC.
