CNC machining zvinhu
Plastics ndechimwe chinhu chakajairika chinoshandiswa muCNC kutendeuka nekuti inowanikwa mune dzakawanda sarudzo dzakasiyana, isingadhure, uye inokurumidza machining nguva.Mapurasitiki anowanzoshandiswa anosanganisira ABS, acrylic, polycarbonate uye naironi.
POM, inozivikanwawo seacetal kana Delrin, ndeye thermoplastic zvinhu zvine semi-crystalline zvivakwa.Iyo inoremekedzwa zvakanyanya nekuda kwesimba rayo rinoshamisa, kuomarara uye kushomeka kwemagetsi.POM inowanzoshandiswa mumashandisirwo anoda kunyatsojeka uye yakaderera friction zvikamu.
POM, inozivikanwawo seacetal kana Delrin, chinhu chinobatika chethermoplastic chinoshandiswa mumhando dzakasiyana dzekushandisa.Hunhu hwayo hwakasiyana hunoita kuti ive yakanakira kugadzira magiya uye mabhengi mumakanika masisitimu.Zvigadzirwa zvemotokari, senge mafuta system zvikamu uye zvemukati trim, zvakare zvinobatsira kubva mukusimba uye kuramba kwePOM.Pamusoro pezvo, POM yakanakisa magetsi insulating zvivakwa inoita kuti ive yakakodzera kushandiswa mumagetsi ekubatanidza.Chekupedzisira, simba rePOM uye hupenyu hurefu hunoita kuti ive sarudzo yakasarudzika yekugadzirwa kwezvinhu zvevatengi senge zipi, matoyi uye midziyo yekubikira.
Nyaya yacho ine simba rinokatyamadza uye inogona kumirisana nemasimba makuru emagetsi.Inopa mafambiro akatsetseka nekukwesha kudiki uye inoshingirira kupfeka.Inochengetedza chimiro chayo uye zviyero mumamiriro ese ezvinhu, ichivimbisa kugadzikana.Mukuwedzera, inopesana nemigumisiro yemakemikari uye inogona kumira kutarisana nezvinhu zvakasiyana-siyana pasina kuora.
Izvo zvinhu zvine kushomeka kwekudzivirira kune UV mwaranzi uye nekudaro inogona kukuvara panguva yekuratidzwa kwenguva refu kuzuva.Zvakare, zvinowanzoitika kumanikidzira kutsemuka pasi pemamwe mamiriro.

POM (Polyoxymethylene), inozivikanwawo seacetal, ipurasitiki yeinjiniya yepamusoro.Iyo semi-crystalline thermoplastic inopa yakanakisa mechaniki simba, kuomarara, uye kugadzikana kwedimensional.POM inowanzoshandiswa muzvikamu zvakaringana, senge magiya, mabhengi, uye zvinhu zvemotokari.
POM ine yakaderera coefficient of friction, iyo inoita kuti ive yakakodzera kune maapplication anoda kushoma kupfeka uye friction.Iyo ine kumira zvakanaka kumakemikari, zvinonyungudutsa, uye mafuta, zvichiita kuti ive yakakodzera kunyorera mumaindasitiri emotokari nemakemikari.POM zvakare ine yakanaka magetsi ekudzivirira zvivakwa uye inogona kumira tembiricha yakakwira.
POM inowanikwa mumhando mbiri huru: homopolymer uye copolymer.Homopolymer POM inopa yakakwira mechaniki kusimba uye kuoma, nepo copolymer POM inopa zvirinani kuramba kuderera kwemafuta uye kurwisa kwemakemikari.
