Xa unyamezelo olugqithisileyo kufuneka luxelwe, okanye xa iimilo zemveliso zintsonkothile kakhulu, okanye xa kufuneka iprototypes enye okanye ezimbini, ukwenziwa kwe [i-imeyile ekhuselweyo] iintlaka zePTFE ziba yindlela enengqiqo yokwenza.
Yonke imisebenzi esemgangathweni-ukuguqula, ukujongana, ukudika, ukubhola, ukuthunga, ukucofa, ukubuyisela kwakhona, ukugaya, njl.-zisebenza kwi-polymer PTFE resins.Umatshini okhethekileyo awuyimfuneko.
Xa umatshini wokwenziwa kweendawo ezivela kwi-polymer PTFE resins, ngesandla okanye ngokuzenzekelayo, umgaqo osisiseko omawukhunjulwe kukuba ezi reins zineempawu ezibonakalayo ngokungafaniyo nezo zezinye imathiriyeli eqhele ukwenziwa ngoomatshini.Zithambile, ukanti zinentwasa.Ziyi-waxT, kodwa zinzima.Bano "imvakalelo" yokusika yobhedu, kodwa umphumo wesixhobo sentsimbi engenasici.Nangona kunjalo, nawuphi na umchwephesha oqeqeshiweyo unokubumba i-polymer PTFE ngokulula kunyamezelo lwe +0.001 intshi kwaye, ngokhathalelo olulodwa, ukuya +0.0005 intshi.
Khetha Izantya ezichanekileyo zokuSebenza
Enye ipropathi ye-polymer PTFE resins ezinefuthe elimandla ubuchule bokusebenzisa i-rnachining kukuqhuba kwazo okuphantsi ngokugqithisileyo kwe-thermal.Ayenzi okanye ifunxe ngokukhawuleza kwaye ikhuphe ubushushu obuveliswa kwinqanaba lokusika.Ukuba ubushushu obuninzi obuveliswayo bugcinwe kwindawo yokusika, kuya kuthambekela ekunciphiseni isixhobo kunye nokutshisa i-resin.Izinto ezipholileyo, ke, zinqweneleka ngexesha lomsebenzi womatshini, ngakumbi ngaphezulu kwesantya esiphezulu se-I50 m/min (500 fpm).
Xa kudityaniswa ne-conductivity ephantsi, ukwanda kwe-thermal ye-polymer PTFE resins (phantse amaxesha e-IQ eentsimbi) kunokubangela iingxaki ezongezelelweyo.Nasiphi na isizukulwana kunye nendawo yokushisa okugqithisileyo kuya kubangela ukwandiswa kwezinto ze-fluoropolymer kuloo ndawo.Ngokuxhomekeke kubukhulu becandelo kunye nokusebenza okwenziwayo, ukwandiswa kwe-Iocalised kunokubangela ukugqithisa okanye ukugqithisa, kunye nokubhoboza umngxuma oqingqiweyo.
Iinkqubo zoMatshini ke, ngakumbi isantya sokusebenza, kufuneka zithathele ingqalelo i-conductivity kunye neziphumo zokwandisa.
Izantya zomphezulu ukusuka kwi-60-150 m/min (200-500 fpm) zonelisa kakhulu kwimisebenzi yokuguqula ukugqiba;kwezi nkcazo, izinto zokupholisa izandyondyo azifuneki.Izantya eziphezulu zingasetyenziswa ngokutya okuphantsi kakhulu okanye ukusika ngokurhabaxa, kodwa izinto zokupholisa ziba yimfuneko ekususeni ubushushu obuveliswe ngokugqithisileyo.Isipholisi esilungileyo siquka amanzi kunye ne-oyile enyibilikayo emanzini ngokomlinganiselo we-10:1 ukuya kuma-20:I.
Ukutya kwe-60-150 m / min (200-500 frm) uluhlu lwesantya kufuneka luqhube i-berween 0.05-0.25 mm (0.002-0.010 intshi) nge-revolurion nganye.Ukuba ukugqiba ukusika yinto yokusebenza kwesantya esiphezulu (umzekelo, umatshini wokujija ozenzekelayo osebenza kuma-240 m/min [800 fp-]), ngoko ke i-fied musr iwiswe kwixabiso eliphantsi ngokuhambelanayo.Ubunzulu obucetyiswayo bokunqunyulwa buhluka kwi-0.005-6.3 mm (0.0002- 0.25 intshi).
Kwimisebenzi yokugaya, ukuhamba phambili kwesixhobo kufuneka kubanjwe kwi-0.13-0.23 mm (0.005-0.009 intshi) nge-revolution.Kungabonakala kunenzuzo ukugrumba ngentshukumo yangaphakathi ukuvumela ukulahlwa kobushushu kwisipholisi.
