Zida Zam'mwamba Zapulasitiki Zapamwamba za CNC
Kodi zenizeni zamitundu yosiyanasiyana ya CNC ndi chiyani?
CNC Machining akhoza kupanga mbali pafupifupi zitsulo kapena pulasitiki.Zopindulitsa za zinthu izi ndi:
1. Mphamvu zamakina: zomwe zimawonetsedwa ndi mphamvu zokolola;
2. machinability: kumasuka kwa makina kumakhudza mtengo wa CNC;
3. mtengo wa zinthu;
4. kuuma: makamaka zitsulo;
5. kutentha kukana: makamaka kwa mapulasitiki.
CNC Zitsulo
Mapulogalamu omwe amafunikira mphamvu zambiri, kuuma, ndi kukana kutentha amagwiritsa ntchito zitsulo kapena, m'malo mwake, ma alloys achitsulo.
1.Aluminiyamu: amagwiritsidwa ntchito popanga zida zachitsulo ndi ma prototypes.
2.Chitsulo chosapanga dzimbiriamatha kuwotcherera, kupangidwa ndi makina, ndi kupukutidwa mosavuta.
3.Chitsulo chochepa, kapena chitsulo chochepa cha carbon: amagwiritsidwa ntchito pazigawo zamakina, ma jigs, ndi zosintha.
4.Chitsulo chachitsulolili ndi zinthu zina zophatikizira kuphatikiza kaboni kuti zithandizire kulimba, kulimba, kutopa, komanso kukana kuvala.
5.Chida chitsulondizothandiza pazida zopangira zinthu monga ma dies, masitampu, ndi nkhungu.
6.MkuwaNdi yabwino kwa mapulogalamu omwe amafunikira kukangana kochepa komanso kamangidwe kake kuti apange magawo owoneka ngati golide pazokongoletsa.
CNC Plastiki
Pulasitiki ndi zinthu zopepuka zokhala ndi mawonekedwe osiyanasiyana, zomwe nthawi zambiri zimagwiritsidwa ntchito pakukana kwawo kwamankhwala komanso mawonekedwe amagetsi.
1.ABS: Nthawi zambiri amagwiritsidwa ntchito popanga ma prototypes asanapangidwe misa ndi jekeseni.
2.Nylon, or polyamide (PA): Amagwiritsidwa ntchito makamaka pazaumisiri chifukwa cha makina ake abwino kwambiri, mphamvu zake, komanso kukana kwamankhwala ndi ma abrasion.
3.Polycarbonatenthawi zambiri imakhala yowoneka bwino, kupangitsa kuti ikhale yoyenera kugwiritsa ntchito zambiri, monga zida zamadzimadzi kapena kunyezimira kwamagalimoto.
POM (Delrin) ndiye chinthu chosankha pa makina a CNC pomwe magawo amafunikira:
1. kulondola kwambiri
2. kukhazikika kwakukulu
3. kukangana kochepa
4. kwambiri dimensional bata pa kutentha kwambiri
5. Mayamwidwe otsika kwambiri amadzi.
PTFE (Teflon) imalimbana ndi kutentha kopitilira 200 ° C ndipo, chifukwa chake, ndi insulator yabwino kwambiri yamagetsi.
High-density polyethylene (HDPE) ndiyoyenera kugwiritsidwa ntchito panja ndi mapaipi.
PEEK: Amagwiritsidwa ntchito makamaka m'malo mwa zitsulo chifukwa cha kuchuluka kwake kwamphamvu ndi kulemera kwake.Magiredi azachipatala amapezekanso, kupangitsa PEEK kukhalanso yoyenera kugwiritsa ntchito zamankhwala.
CNC Composite Zida
Ma Composites, m'mawu osavuta, ndizinthu zingapo zomwe zimakhala ndi mawonekedwe osiyanasiyana akuthupi ndi mankhwala omwe amaphatikizidwa kuti apange chinthu champhamvu, chopepuka, kapena nthawi zina chosinthika.
Chimodzi mwazinthu zodziwika bwino pamsika ndipulasitiki yolimbikitsidwa.Masiku ano, pulasitiki imagwiritsidwa ntchito mwanjira yoyera pazinthu zambiri, monga zoseweretsa ndi mabotolo amadzi.Komabe, imatha kulimbikitsidwa ndi ulusi wochokera kuzinthu zina.Njira imeneyi imapangitsa ena mwamagulu amphamvu kwambiri, opepuka, komanso osunthika kwambiri kupezeka.
Kugwiritsiridwa ntchito kofala kwa kompositi ndiko kulimbikitsa chinthu choyera ndi ulusi kuchokera ku china choyera kapena chophatikizika.Wopanga nthawi zambiri amawonjezeraulusi wa carbon kapena graphiteku kompositi.Ulusi wa kaboni umakhala wochititsa chidwi, umakhala ndi kuphatikiza kodabwitsa kwa ma modulus apamwamba komanso kulimba kwamphamvu, umakhala ndi CTE yotsika kwambiri (yoyipa pang'ono) (gawo la kukulitsa kwamafuta), ndipo imathandizira kukana kutentha kwambiri.Makhalidwewa amapanga mpweya wabwino kwambiri pamabizinesi osiyanasiyana, ndipo umalumikizana mosavuta ndi zida zingapo.
Kuwonjezera pa carbon,galasi la fiberglassndi chinthu chodziwika bwino cha fiber reinforcement.Fiberglass si yamphamvu kapena yolimba ngati mpweya wa carbon, koma ili ndi makhalidwe enaake omwe amachititsa kuti ikhale yofunikira mu ntchito zambiri.Ulusi wagalasi siwoyendetsa (mwachitsanzo, chotchingira) ndipo nthawi zambiri suwoneka pamitundu yambiri yotumizira.Izi zimapangitsa kukhala chisankho chabwino pamapulogalamu amagetsi kapena owulutsa.
Ma resinndi gawo lofunikira la kompositi.Ndi matrices omwe amagwirizanitsa zida zosiyana popanda kusakanikirana kwathunthu kukhala chinthu chimodzi choyera.
