Aluminiyamu CNC Machining njira

Mukhoza makina aluminiyumu ndi angapo CNC Machining njira zilipo lero.Zina mwa njirazi ndi izi.

Kutembenuka kwa CNC
Potembenuza CNC, chogwirira ntchito chimazungulira, pomwe chida chodulira chimodzi chimakhala chokhazikika pambali pake.Kutengera ndi makina, mwina chogwirira ntchito kapena chida chodulira chimayendetsa chakudya motsutsana ndi chinacho kuti chikwaniritse kuchotsa zinthu.

CNC Milling
CNC Milling ntchito ndi ambiri ntchito machining mbali zotayidwa.Ntchitozi zimaphatikizapo kuzungulira kwa nsonga zamitundu yambiri motsatira mbali yake, pomwe chogwirira ntchito chimakhala choyima motsatira mbali yake.Kudula kuchitapo kanthu ndikuchotsa zinthu kumatheka ndi kayendedwe ka chakudya kachipangizo, chida chodulira, kapena zonse ziwiri kuphatikiza.Kusuntha uku kungathe kuchitidwa ndi nkhwangwa zingapo.

CNC Drilling
CNC Drilling ndi njira yopangira dzenje mu workpiece.Pantchitoyi, chida chodulira chamitundu yambiri chozungulira cha kukula kwake chimasuntha molunjika mpaka pamtunda kuti chibowoledwe, potero kumapanga dzenje.

Zida zopangira ma aluminium
Pali zinthu zingapo zomwe zimakhudza kusankha kwa chida cha aluminiyamu CNC Machining.

Kupanga zida
Pali mbali zosiyanasiyana za zida za geometry zomwe zimathandizira kuti zitheke kupanga aluminiyamu.Chimodzi mwa izi ndi kuchuluka kwake kwa zitoliro.Pofuna kupewa zovuta pakutulutsa kwa chip pa liwiro lalikulu, zida zodulira za aluminiyamu CNC Machining ziyenera kukhala ndi zitoliro 2-3.Kuchuluka kwa zitoliro kumabweretsa zigwa zing'onozing'ono za chip.Izi zipangitsa kuti tchipisi zazikulu zopangidwa ndi ma aluminiyamu aloyi atseke.Pamene mphamvu zodulira zili zochepa ndipo chilolezo cha chip ndichofunika kwambiri pa ntchitoyi, muyenera kugwiritsa ntchito zitoliro ziwiri.Kuti mugwiritse ntchito bwino chip clearance ndi mphamvu ya zida, gwiritsani ntchito zitoliro zitatu.

Zitoliro za zida (harveyperformance.com)
Helix angle
Ngodya ya helix ndi ngodya yomwe ili pakati pa mzere wapakati wa chida ndi mzere wowongoka wa tangent m'mphepete mwake.Ndi mbali yofunika ya zida kudula.Pomwe ngodya yayikulu ya helix imachotsa tchipisi mwachangu, imawonjezera kukangana ndi kutentha panthawi yodula.Izi zitha kupangitsa kuti tchipisi tiwotcherera pazida pamwamba pa makina othamanga kwambiri a aluminium CNC.Mbali yotsika ya helix, kumbali ina, imatulutsa kutentha pang'ono koma sikungachotse tchipisi bwino.Popanga aluminiyamu, 35 ° kapena 40 ° helix angle ndi yoyenera kugwiritsira ntchito roughing, pamene ngodya ya helix ya 45 ° ndiyo yabwino kwambiri kumaliza.

Chilolezo angle
Clearance angle ndi chinthu china chofunikira pakugwira bwino ntchito kwa chida.Kutentha kwakukulu kumapangitsa kuti chipangizocho chizigwira ntchito ndi kuyankhulana.Kumbali ina, ngodya yaying'ono kwambiri ingayambitse mkangano pakati pa chida ndi ntchito.Ma angles ochotsera pakati pa 6 ° ndi 10 ° ndi abwino kwambiri pamakina a aluminiyamu a CNC.

Zida zothandizira
Carbide ndiye chida chomwe chimakondedwa pazida zodulira zomwe zimagwiritsidwa ntchito mu aluminiyamu CNC Machining.Chifukwa aluminium ndi kudula kofewa, chomwe chili chofunikira mu chida chodulira cha aluminiyamu sichimalimba, koma kutha kusunga lumo lakuthwa.Kutha kumeneku kulipo mu zida za carbide ndipo zimatengera zinthu ziwiri, kukula kwambewu ya carbide ndi chiŵerengero cha binder.Ngakhale kuti chimanga chokulirapo chimapangitsa kuti chikhale cholimba, kukula kwanjere kakang'ono kumapangitsa kuti pakhale zinthu zolimba, zosagwira ntchito zomwe kwenikweni ndizomwe timafunikira.Mbewu zing'onozing'ono zimafunikira cobalt kuti zitheke bwino komanso mphamvu zake.

Komabe, cobalt imakhudzidwa ndi aluminiyumu pa kutentha kwakukulu, kupanga m'mphepete mwa aluminiyumu pamwamba pazida.Chofunikira ndikugwiritsa ntchito chida cha carbide chokhala ndi cobalt yoyenera (2-20%), kuti muchepetse izi, ndikusungabe mphamvu zofunikira.Zida za Carbide zimatha kupirira bwino kuposa zida zachitsulo, kuthamanga kwambiri komwe kumalumikizidwa ndi ma aluminium CNC Machining.

Kuphatikiza pa zida za zida, kupaka zida ndizofunikira kwambiri pakudula zida.ZrN (Zirconium Nitride), TiB2 (Titanium di-Boride), ndi zokutira ngati diamondi ndi zokutira koyenera kwa zida zomwe zimagwiritsidwa ntchito popanga ma aluminium CNC Machining.

Zakudya ndi liwiro
Kudula liwiro ndi liwiro lomwe chida chodulira chimazungulira.Aluminiyamu imatha kupirira kuthamanga kwambiri chifukwa chake kuthamanga kwazitsulo zotayidwa kumadalira malire a makina omwe akugwiritsidwa ntchito.Liwiro liyenera kukhala lokwera kwambiri monga momwe limagwirira ntchito muzitsulo za aluminiyamu za CNC, chifukwa izi zimachepetsa kuthekera kwa mapangidwe a m'mphepete mwake, zimapulumutsa nthawi, zimachepetsa kutentha kwa gawolo, kumapangitsa kuti chip chiwonongeke, komanso kumaliza.Liwiro lenileni lomwe limagwiritsidwa ntchito limasiyanasiyana ndi aloyi ya aluminiyamu ndi kukula kwa chida.

Mtengo wa chakudya ndi mtunda womwe chogwirira ntchito kapena chida chimayenda pakasinthasintha kwa chida.Chakudya chomwe chimagwiritsidwa ntchito zimadalira kumaliza komwe mukufuna, mphamvu, komanso kulimba kwa chogwiriracho.Kudula movutikira kumafuna chakudya cha 0.15 mpaka 2.03 mm/rev pomwe kumaliza kudula kumafuna chakudya cha 0.05 mpaka 0.15mm/rev.

Kudula madzimadzi
Ngakhale kuti ndi makina ake, musamadule aluminiyumu mouma chifukwa izi zimathandizira kupanga m'mphepete mwake.Madzi odulira oyenera a aluminiyamu CNC Machining ndi emulsions yamafuta osungunuka ndi mafuta amchere.Pewani kudula madzi omwe ali ndi chlorine kapena sulfure yogwira ntchito chifukwa zinthuzi zimadetsa aluminiyamu.
