1. Dab tsi yog nylon thiab vim li cas nws zoo tagnrho rauCNC Machining?
Nylon (lub npe: polyamide) yog qhov siab -} {{}}}}}}}}}}}}}}}}}}}} qhib polymerization ntawm lactams. Txij li Dupont qhia thawj Nylon 6 nyob rau xyoo 1930, nws tau dhau los ua nws cov kev siv hluav taws xob ntau zaus, hnav tsis kam, thiab lub teeb ua haujlwm tsis kam, thiab lub teeb yuag.
2. Cov yam ntxwv core ntawm machinable nylon thiab nws cov txiaj ntsig hauv CNC machining
Cov Khoom Siv Neeg Kho Tshuab
Lub zog tensile: pa66 tuaj yeem ncav cuag 80-100 MPa, piv rau txhuas alloy thiab deb tshaj abs (40-50 MPa);
Hnav Kuj: nws tus kheej - Lubricious lub zog yog qhov pom zoo dua rau kev tsim khoom, bushings, thiab lwm yam kev tsiv chaw;
Qhov kub kub kuj: iav {{- reaPlectived nylon tuaj yeem tiv thaiv nylon tau tshaj li ntawm 220 degree).
CNC Machining Adjanced: Vim li cas xaiv Nylon rau cnc?
Lub teeb yuag: qhov ceev ntawm tsuas yog 1.1-1.5 g / cm³, tshaj 50% sib dua 50% dua 50% dua li hlau, haum rau aerospace tsho khuam;
Tus nqi -}}}}}}} Cov ntaub ntawv raw khoom yog qis dua cov uas muaj cov pob zeb tshwj xeeb zoo li PTFE thiab peek, nrog kev ua haujlwm siab dua;
Qhov seem ruaj khov: noo noo kev yeem tiv thaiv tsis tau muaj peev xwm tawm los ntawm kev kho kom qhuav (piv txwv li 80 teev), ntsib qhov yuav tsum muaj rau qhov chaw ntsuas.
3. Cov txheej txheem tseem ceeb thiab tsis muaj rau cnc machining ntawm nylon
Kev cov nyom thiab cov kev daws teeb meem
Thermal rhiab: txiav kev sib txhuam tuaj yeem ua rau cov khoom muag hauv zos (yuav tsum tau cov cuab yeej ua kom muaj zog hauv zos (yuav tsum tau muaj cov cuab yeej cua txias (uas muaj cua txias
Chip tuav: Nylon chips yuav zoo li qhwv ib ncig twj, xav tau cov cuab yeej nrog cov ces kaum (15 degree-siab (0.002-0.006 nti / hniav).
