Uma ukubekezelelana okwedlulele kufanele kucaciswe, noma uma izimo zomkhiqizo ziyinkimbinkimbi kakhulu, noma lapho kudingeka iphrothotype eyodwa noma ezimbili, ukucutshungulwa [kwe-imeyili evikelwe] amareyini e-PTFE kuba indlela enengqondo yokwenza.
Yonke imisebenzi ejwayelekile-ukuguqula, ukubheka, ukubhora, ukubhoboza, ukuxhuma, ukucofa, ukuphinda, ukugaya, njll.-kuyasebenza kuma-polymer PTFE resins.Imishini ekhethekile ayidingekile.
Lapho kwenziwa izingxenye ze-polymer PTFE resins, ngokwenza noma ngokuzenzakalelayo, umthetho oyisisekelo okufanele ukhunjulwe ukuthi lawa ma-resin anezinto ezibonakalayo ngokungafani nalezo zanoma iyiphi enye impahla evame umshini.Athambile, nokho aluhlaza.Ziyi-waxT, nokho ziqinile.“Zinomuzwa” wokusika wethusi, nokho umphumela wokugqoka kwamathuluzi wensimbi engagqwali.Noma kunjalo, noma yimuphi uchwepheshe wemishini oqeqeshiwe angakwazi ukubumba i-polymer PTFE ekubekezeleleni okungu-+0.001 intshi futhi, ngokunakekela okukhethekile, iye ku-+0.0005 intshi.
Khetha Izivinini Zokusebenza Ezilungile
Isici esisodwa se-polymer PTFE resins enethonya elinamandla amasu okusebenzisa i-rnachining ukuguquguquka kwawo okushisayo okuphansi kakhulu.Azikutholi futhi azikusheshi ukumunca futhi zikhiphe ukushisa okukhiqizwa endaweni ethile.Uma ukushisa okukhiqizwe okuningi kugcinwa endaweni yokusika, kuzothambekela ekwenzeni ithuluzi libe buthuntu futhi kushise kakhulu inhlaka.Izinto zokupholisa ziyathandeka ngesikhathi sokusebenza komshini, ikakhulukazi ngaphezu kwesivinini esiphezulu esingu-I50 m/min (500 fpm).
Ngokuhambisana nokuhamba kancane, ukunwetshwa okuphezulu okushisayo kwezinhlaka ze-polymer PTFE (cishe izikhathi ze-IQ kunezensimbi) kungadala izinkinga ezengeziwe.Noma isiphi isizukulwane kanye nokwenza kwasendaweni ukushisa okweqile kuzodala ukunwetshwa kwempahla ye-fluoropolymer ngaleso sikhathi.Ngokuya ngokuqina kwesigaba nokusebenza okwenziwayo, ukunwetshwa kwe-Iocalized kungase kubangele ama-overcuts noma ama-undercuts, kanye nokubhoboza imbobo ecijile .
Izinqubo zomshini ke, ikakhulukazi isivinini sokusebenza, kufanele zicabangele imiphumela yokuqhuba kanye nokwandisa.
Izivinini ezingaphezulu ukusuka ku-60-150 m/min (200-500 fpm) zigculisa kakhulu emisebenzini yokujika eqeda kahle;kulawa ma-speecl, izinto zokupholisa izikhukhula azidingeki.Isivinini esiphezulu singasetshenziswa ngokuphakelayo okuphansi kakhulu noma ukusikeka okuqinile, kodwa izinto zokupholisa ziba yimfuneko ukuze kususwe ukushisa okukhiqizwa ngokweqile.Isipholile esihle siqukethe amanzi kanye nowoyela oncibilikayo emanzini ngesilinganiso sika-10:1 kuya ku-20:I.
Okuphakelayo kwebanga lesivinini elingu-60-150 m/min (200-500 frm) kufanele kusebenze i-berween 0.05-0.25 mm (0.002-0.010 inch) i-revolurion ngayinye.Uma ukusika kokuqeda kuyinjongo yokusebenza kwesivinini esikhulu (isb, umshini ozenzakalelayo oyisikulufa osebenza ku-240 m/min [800 fp-]), khona-ke i-fid musr yehliselwa enani eliphansi ngokuhambisanayo.Ukujula okunconyiwe kokusika kuyahluka ukusuka ku-0.005-6.3 mm (0.0002- 0.25 amayintshi).
Emisebenzini yokumba, ukuhamba phambili kwethuluzi kufanele kubanjwe ku-0.13-0.23 mm (0.005-0.009 inch) inguquko ngayinye.Kungase kube nenzuzo ukubhoboza ngokunyakaza kokuphuma ukuze uvumele ukuchithwa kokushisa kupholise.
