Dab tsi ntawm cov cuab yeej txiav feem ntau siv rau hauv kev ua cov hlau cam?
Hom thiab cov yam ntxwv ntawm cov cam khwb cia hlau
CAST hlau raws li nws cov dej num tau muab faib ua: Grey cam khwb cia hlau, Dawb cam khwb cia hlau, Malleable cam khwb cia hlau, Zas hlau, vermicular cam khwb cia hlau, Alloy cam khwb cia hlau thiab lwm yam. Grey cam khwb cia hlau yog siv dav hauv kev lag luam tsheb, thiab kev lag luam tsheb yog qhov thov rau cov cuab yeej NC, yog li feem ntau ua cov nroj tsuag muaj grey hlau ua kev xav tau.
Dab tsi ntawm cov cuab yeej txiav tau siv los ua cov hom hlau nrum
Hauv daim ntawv no, cov hlau cam hom yog grey hlau, zas hlau thiab AUSTENITE CAST IRON, grey hlau ua tiav kev ua tau zoo, xws li kev siv alumina txheej carbide milling cutter, feem ntau muaj peev xwm rau grey hlau txiav. Vim tias ntawm lub ntsej muag ntawm graphite cov ntsiab lus ntawm kev ua haujlwm ntawm SPHEROIDAL graphite cam khwb cia hlau, kev lag luam coated alloy milling cutter nrog sib xyaw hard alloy bar siv tau.
Cov dog dig cam khwb cia hlau ua cov cuab yeej, cov yig tungsten steel milling cutter tuaj yeem tsim nyog. Thib ob, kev kub ceev steel txiav cov cuab yeej muaj cov kabmob cobalt siv tau.
Dab tsi ntawm cov cuab yeej txiav tau siv rau qhov nyuaj-rau-txheej txheem cam khwb cia hlau
COLD-HARD CAST IRON, txias-tawv cam khwb cia hlau yog ib hom hnav-resistant cam khwb cia hlau, nws yog nyob rau hauv cov cam khwb cia hlau los ntawm kev ua kom sai txheej txheej ntawm cam khwb cia hlau txias kom tos ib pliag, kom nws txheej txheej kom tau txais ib qho encyclopedia ntawm cam khwb cia hlau qauv, sib sau ua lub siab hardness, siab hnav-resistant tus yam ntxwv. Chilled cam khwb cia hlau yuav muab faib ua dog dig chilled cam khwb cia hlau, NI-CR chilled cam khwb cia hlau, siab chromium dawb hlau thiab chromium-vanadium dawb hlau thiab hais txog.
1) machining cov yam ntxwv ntawm chilled cam khwb cia hlau
Lub hardness ntawm chilled cam khwb cia hlau yog siab heev, Brittleness yog loj heev, chav txiav txiav quab yuam kuj tseem loj heev, thiab nws cov nti muaj qhov tawg, vim tias lub cuab yeej cov lus yog nyob rau hauv kev sib cuag nrog kev txiav, lub zog txiav thiab txiav txiav kub yog cov nyob ze ze ntawm ntug txiav, yooj yim ua rau cov cuab yeej hnav thiab tsim kua muag. Kev ua ntawm cov hlau ntuag hlau ua rau feem ntau yog ntxhib, thiab cov nyiaj tau los ntawm lub tshuab yog qhov loj thiab tsis sib xws, uas ua rau txoj kev nyuaj ntawm kev nrum hlau ua. Tau kawg, tam sim no cov hlau ua cov cuab yeej ua, cam hlau txiav cutter, thiab yog li muaj cov tshuaj zoo heev.
2) kev xaiv ntawm kev txiav cov cuab yeej rau machining chilled cam khwb cia hlau
Qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm txias-tawv nrum hlau yog siab hardness, hnav tsis kam, nrog lub zog ntawm cov cuab yeej cov khoom siv. Feem ntau, YG hom cemented carbide lossis alumina ceramic cuab yeej nrog cov nplua zoo los yog ultra-nplua grain txheej yog siv.
3) qhov txiav txiav ntau ntawm txias txias cam khwb cia hlau milling cutter
Cov cuab yeej carbide; loj noj nyob rau ntawm tsawg ceev. V=9m / min, pub ntim feem ntau raws li lub ntsiab loj ntawm lub kaum sab xis thiab rov qab noj riam rau xaiv. 0.5 MM / R rau ntxhib machining thiab 0.1 ー 0.4 hli / r rau ua tiav machining ntawm cam khwb cia hlau.
Kev kub ceev milling, ntxhib thiab ib nrab tiav CAST IRON V=50 ~ 80m / min, thiab ua tiav machining V=80 ~ 120m / min.
CAST hlau ua cov cuab yeej, xws li riam cov riam, tuaj yeem ua kom ntxhib, semi thiab nplua. Yog tias koj tsis paub dab tsi siv cam khwb cia hlau txiav cutter, Txheej Txheem Hlau Milling Tshuab Cutter yog ntawm chav kawm xaiv hom YG carbide cutter.
