Izixhobo zoomatshini be-CNC
Umatshini wokugaya i-CNC kwi-POM
Iiplastiki zezinye izinto eziqhelekileyo ezisetyenziswa ekuguquleni i-CNC kuba zifumaneka ngeendlela ezahlukeneyo, azibizi kakhulu, kwaye zikhawuleza kakhulu ukwenziwa. Iiplastiki ezisetyenziswa rhoqo ziquka i-ABS, i-acrylic, i-polycarbonate kunye ne-nylon.
Inkcazo yePOM (iPolyoxymethylene)
I-POM, ekwaziwa ngokuba yi-acetal okanye i-Delrin, yinto eyenziwe nge-thermoplastic eneempawu ze-semi-crystalline. Ixatyiswa kakhulu ngenxa yamandla ayo angaqhelekanga, ukuqina kwayo kunye neempawu zokungqubana okuncinci. I-POM idla ngokusetyenziswa kwiindawo ezifuna ukuchaneka kunye nezixhobo zokungqubana okuncinci.
Isicelo
I-POM, eyaziwa ngokuba yi-acetal okanye i-Delrin, yinto eguquguqukayo ye-thermoplastic esetyenziswa kwiintlobo ngeentlobo zezicelo. Iimpawu zayo ezikhethekileyo zenza ukuba ilungele ukuvelisa izixhobo kunye neebheringi kwiinkqubo zoomatshini. Izixhobo zezithuthi, ezifana nezixhobo zenkqubo yepetroli kunye nokuhlobisa kwangaphakathi, nazo ziyazuza kukuqina kunye nokumelana kwe-POM. Ukongeza, iimpawu zokukhusela umbane ezibalaseleyo ze-POM zenza ukuba ifaneleke ukusetyenziswa kwizihlanganisi zombane. Okokugqibela, amandla kunye nobude be-POM kwenza kube lukhetho olukhethwayo kwimveliso yezinto zabathengi ezifana nee-zipper, iithoyi kunye nezixhobo zasekhitshini.
Amandla
Le nto inamandla amangalisayo kwaye inokumelana namandla amakhulu oomatshini. Inika intshukumo egudileyo kunye nokungqubana okuncinci kwaye ayigugi. Igcina imo yayo kunye nobukhulu bayo kuzo zonke iimeko, iqinisekisa uzinzo. Ukongeza, ayigugi kwimiphumo yeekhemikhali kwaye inokumelana nokuchatshazelwa zizinto ezahlukeneyo ngaphandle kokuwohloka.
Ubuthathaka
Le nto inamandla okuxhathisa imitha ye-UV kwaye ngenxa yoko isengozini yokonakala xa ichaphazeleka lilanga ixesha elide. Kwakhona, inokuba neengxwelerha zoxinzelelo phantsi kweemeko ezithile.

Ulwazi lwesayensi oludumileyo malunga ne-POM
I-POM (iPolyoxymethylene), eyaziwa ngokuba yi-acetal, yiplastiki yobunjineli esebenza kakhulu. Yi-thermoplastic e-semi-crystalline enika amandla abalaseleyo oomatshini, ukuqina, kunye nozinzo olulinganayo. I-POM isetyenziswa rhoqo kwiindawo ezichanekileyo, ezifana neegiya, iibheringi, kunye nezixhobo zemoto.
I-POM ine-coefficient ephantsi yokungqubana, nto leyo eyenza ukuba ifaneleke kwiindlela ezifuna ukuguguleka okuncinci nokungqubana. Iyakwazi ukumelana neekhemikhali, izinyibilikisi kunye namafutha, nto leyo eyenza ukuba ifaneleke kwiindlela zokusetyenziswa kwiimoto nakwiikhemikhali. I-POM ikwanazo neempawu ezilungileyo zokugquma umbane kwaye inokumelana namaqondo obushushu aphezulu.
I-POM ifumaneka kwiindidi ezimbini eziphambili: i-homopolymer kunye ne-copolymer. I-Homopolymer POM inika amandla aphezulu oomatshini kunye nokuqina, ngelixa i-copolymer POM inika ukumelana okungcono nokuwohloka kobushushu kunye nokuhlaselwa ngamakhemikhali.
