Kupanga ndi Kupanga kwa PTFE - Kuthamanga Kwantchito

Pamene kulolerana kwakukulu kuyenera kufotokozedwa, kapena pamene mawonekedwe a mankhwala ali ovuta kwambiri, kapena pamene prototypes imodzi kapena ziwiri zimafunika, makina a [imelo otetezedwa] PTFE resins amakhala njira zomveka zopangira.

Ntchito zonse zokhazikika-kutembenuza, kuyang'ana, kutayirira, kubowola, kupukuta, kugwedeza, kubwezeretsanso, kugaya, etc.-zikugwiritsidwa ntchito ku polima PTFE resins.Makina apadera si ofunika.

Mukamapanga ma resin a polima a PTFE, pamanja kapena pawokha, lamulo lofunika kukumbukira ndikuti utomoniwu uli ndi zinthu zakuthupi mosiyana ndi zazinthu zina zomwe zimagwiritsidwa ntchito nthawi zambiri.Iwo ndi ofewa, komabe amphumphu.Iwo ndi waxT, komabe olimba.Amakhala ndi "kumverera" kwa mkuwa, komabe amavala zida zachitsulo chosapanga dzimbiri.Komabe, katswiri wamakina aliyense wophunzitsidwa amatha kupanga polima PTFE mosavuta kuti azitha kulekerera +0.001 inchi ndipo, mosamala kwambiri, mpaka +0.0005 inchi.

Sankhani Mayendedwe Olondola Ogwira Ntchito

Katundu wina wa ma polima PTFE resins omwe amalimbikitsa kwambiri njira zowotchera ndi kutsika kwawo kotentha kwambiri.Sachita kapena kuyamwa mwachangu ndikutaya kutentha komwe kumapangidwa pamphepete.Ngati kutentha kochuluka kopangidwa kumasungidwa pamalo odulira, kumapangitsa kuti chidacho chiziwotcha komanso kutenthetsa utomoni.Zoziziritsa, ndiye, ndizofunikira panthawi yopanga makina, makamaka pamwamba pa liwiro la I50 m/min (500 fpm).

Kuphatikizidwa ndi kutsika kwamphamvu, kuwonjezereka kwa kutentha kwa ma polima PTFE resins (pafupifupi IQ nthawi ya zitsulo) kungayambitse mavuto owonjezera.M'badwo uliwonse ndi kufalikira kwa kutentha kwakukulu kumayambitsa kukula kwa zinthu za fluoropolymer panthawiyo.Kutengera makulidwe a gawolo ndi ntchito yomwe ikuchitika, kukulitsa kwa Iocalized kumatha kubweretsa kupitilira kapena kutsika, ndikubowola dzenje la tapered.

Njira zogwirira ntchito ndiye, makamaka kuthamanga kwa ntchito, ziyenera kuganiziridwa ndi ma conductivity ndi kukulitsa.

Kuthamanga kwapamtunda kuchokera ku 60-150 m/min (200-500 fpm) ndikokhutiritsa kwambiri pakutembenuza komaliza;paziwerengerozi, zoziziritsira madzi osefukira sizifunikira.Kuthamanga kwambiri kungagwiritsidwe ntchito ndi zakudya zochepa kwambiri kapena zodula kwambiri, koma zoziziritsira zimakhala zofunikira kuti zichotse kutentha kochuluka.Chozizirira chabwino chimakhala ndi madzi kuphatikiza mafuta osungunuka m'madzi mu chiyerekezo cha 10: 1 mpaka 20: I.

Kudyetsa kwa liwiro la 60-150 m/min (200-500 frm) kuyenera kuyenda pakati pa 0.05-0.25 mm (0.002-0.010 inchi) pakusintha.Ngati kudula komaliza ndi ntchito yothamanga kwambiri (mwachitsanzo, makina opangira makina opangira 240 m/min [800 fp-]), ndiye kuti chakudya cha musr chitsitsidwe pamtengo wotsikiranso.Kuzama kovomerezeka kumasiyanasiyana kuchokera ku 0.005-6.3 mm (0.0002- 0.25 inchi).

Pobowola, kuyenda kutsogolo kwa chida kuyenera kuchitika mpaka 0.13-0.23 mm (0.005-0.009 inchi) pakusintha.Zitha kukhala zopindulitsa kubowola ndikulowa mkati kuti mulole kutentha kulowe mu chozizirira.
