Cov khoom tsim nyog rau precision machining feem ntau suav nrog stainless hlau (xws li SUS303), dawb- txiav hlau (xws li 12L15, 10S20), aluminium alloys (xws li 6061, 7075), tooj liab alloys (xws li H59, C31000 leaded brass), thiab titanium alloys. Cov ntaub ntawv no tau siv dav hauv kev tsim cov khoom siv siab - qhov tseeb vim lawv cov machinability zoo, qhov ruaj khov, thiab lub zog siab.
Common precision machining cov ntaub ntawv thiab lawv cov yam ntxwv:
Stainless hlau (xws li SUS303): Corrosion-resistant thiab hnav-resistant, feem ntau siv hauv cov khoom siv kho mob thiab khoom noj khoom haus. Txawm li cas los xij, nws yog nquag ua raws li cov cuab yeej txiav thaum lub sij hawm machining, yuav tsum tau siv cov coolant tshwj xeeb thiab cov cuab yeej txiav.
Dawb- txiav hlau (xws li 12L15, 10S20): Muaj cov sulfur los txhim kho nti tawg kev ua haujlwm, ua rau muaj kev ua haujlwm siab thiab ua kom zoo, haum rau kev tsim khoom loj ntawm cov khoom tsis yog - tus qauv fasteners thiab connectors.
Aluminium Alloys (6061, 7075)
6061: Lub teeb yuag, zoo thermal conductivity, thiab du machining; feem ntau siv hauv aerospace thiab hluav taws xob vaj tsev.
7075: Lub zog ze rau cov hlau; haum rau siab - load Cheebtsam, tab sis kim dua thiab nquag tawg; yuav tsum tau tsawg-kev ceev machining.
Copper Alloys (H59 Brass, C31000 Lead Brass)
H59: Zoo heev machinability; siv nyob rau hauv manufacturing precision iav thiab li qub.
C31000: Cov ntsiab lus txhuas txhim kho lubricity; txheeb ze machinability ncav cuag 75%, haum rau micron -theem hluav taws xob txuas machining.
Titanium Alloys (piv txwv li, TC4): Lub zog muaj zog, tsis tshua muaj lub ntiajteb txawj nqus, thiab corrosion kuj; dav siv nyob rau hauv aerospace thiab kev kho mob implants. Txawm li cas los xij, tsis zoo thermal conductivity; yuav tsum muaj siab - cua txias thaum lub sij hawm machining los tiv thaiv lub zos overheating thiab deformation.
Engineering Plastics (xws li PTFE, PEEK)
PTFE: Resistant mus rau acids thiab alkalis, siv nyob rau hauv tshuaj sealing Cheebtsam, tab sis muaj tsis zoo seem stability thiab yuav tsum tau them nyiaj yug.
PEEK: Kub kub tsis kam (260 degree) thiab lub zog siab, dhau los ua qhov kev xaiv tshiab rau qhov tseeb hauv cov tsheb tshiab, tab sis nrog cov nqi ua haujlwm siab.
