Zipangizo zopangira makina a CNC
Kukonza CNC mu POM
Mapulasitiki ndi chinthu china chofala chomwe chimagwiritsidwa ntchito potembenuza CNC chifukwa chimapezeka m'njira zosiyanasiyana, ndi otsika mtengo, ndipo nthawi yopangira zinthu imakhala yofulumira. Mapulasitiki omwe amagwiritsidwa ntchito kwambiri ndi monga ABS, acrylic, polycarbonate ndi nayiloni.
Kufotokozera kwa POM (Polyoxymethylene)
POM, yomwe imadziwikanso kuti acetal kapena Delrin, ndi chinthu chopangidwa ndi thermoplastic chomwe chili ndi mphamvu ya semi-crystalline. Chimalemekezedwa kwambiri chifukwa cha mphamvu zake zapadera, kuuma kwake komanso mphamvu zake zochepa zokangana. POM nthawi zambiri imagwiritsidwa ntchito popanga zinthu zomwe zimafuna kulondola komanso kukangana kochepa.
Kugwiritsa ntchito
POM, yomwe imadziwikanso kuti acetal kapena Delrin, ndi chinthu chopangidwa ndi thermoplastic chomwe chimagwiritsidwa ntchito m'njira zosiyanasiyana. Kapangidwe kake kapadera kamapangitsa kuti ikhale yoyenera kupanga magiya ndi ma bearing m'makina. Zigawo zamagalimoto, monga zigawo zamakina amafuta ndi zokongoletsera zamkati, zimapindulanso ndi kulimba ndi kukana kwa POM. Kuphatikiza apo, mphamvu zabwino kwambiri za POM zotetezera magetsi zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazolumikizira zamagetsi. Pomaliza, mphamvu ndi moyo wautali wa POM zimapangitsa kuti ikhale chisankho chabwino kwambiri popanga zinthu monga zipi, zoseweretsa ndi ziwiya zakukhitchini.
Mphamvu
Zipangizozi zili ndi mphamvu zodabwitsa ndipo zimatha kupirira mphamvu zazikulu zamakina. Zimapereka kuyenda kosalala komanso kukanda kochepa komanso sizimawonongeka. Zimasunga mawonekedwe ake ndi kukula kwake muzochitika zonse, kuonetsetsa kuti zimakhala zokhazikika. Kuphatikiza apo, sizimakhudzidwa ndi mankhwala ndipo zimatha kupirira kukhudzana ndi zinthu zosiyanasiyana popanda kuwonongeka.
Zofooka
Zinthuzo zimakhala ndi mphamvu zochepa zotsutsana ndi kuwala kwa UV ndipo motero zimatha kuwonongeka zikagwiritsidwa ntchito kwa nthawi yayitali padzuwa. Komanso, zimatha kukhala ndi ming'alu yamavuto pazifukwa zina.

Chidziwitso chodziwika bwino cha sayansi chokhudza POM
POM (Polyoxymethylene), yomwe imadziwikanso kuti acetal, ndi pulasitiki yopangidwa mwaukadaulo yapamwamba kwambiri. Ndi thermoplastic ya semi-crystalline yomwe imapereka mphamvu yabwino kwambiri yamakina, kuuma, komanso kukhazikika kwa mawonekedwe. POM imagwiritsidwa ntchito kwambiri m'zigawo zolondola, monga magiya, mabearing, ndi zida zamagalimoto.
POM ili ndi mphamvu yochepa yolimbana ndi kutentha, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito zomwe sizifuna kuwonongeka kwambiri. Ili ndi mphamvu yolimbana ndi mankhwala, zosungunulira, ndi mafuta, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'mafakitale a magalimoto ndi mankhwala. POM ilinso ndi mphamvu zabwino zotetezera kutentha kwa magetsi ndipo imatha kupirira kutentha kwambiri.
POM imapezeka m'mitundu iwiri ikuluikulu: homopolymer ndi copolymer. Homopolymer POM imapereka mphamvu zambiri zamakaniko ndi kuuma, pomwe copolymer POM imapereka kukana bwino kutentha ndi kuukira kwa mankhwala.
