Thaum koj hnov 'premier precision machining', dab tsi los rau hauv siab? Tej zaum yog chav huv huv, ib lab-duas Swiss tshuab dhos, thiab cov khoom siv nrog kev ua siab ntev uas ua rau koj lub taub hau tig. Qhov ntawd yog ib feem ntawm nws, paub meej, tab sis daim ntawv lo tau cuam tshuam ntau heev nws poob nws ntug. Hauv kuv phau ntawv, nws yog tsawg dua ntawm daim ntawv ci ci thiab ntau ntxiv txog cov txheej txheem gritty, unglamorous ntawm kev cog lus rau tus neeg siv khoom thiab tom qab ntawd tawm hws txhua txhua micron kom nws. Nws yog qhov sib txawv ntawm lub khw uas tuaj yeem ntaus ± 0.005 thiab ib qho uas tuaj yeem tuav ± 0.0002 ntawm ib qho nyuaj Inconel 718 aircraft bracket, batch tom qab batch, thaum tswj thermal drift thiab cov cuab yeej hnav hauv lub sijhawm. Qhov ntawd yog lub toj siab. Ntau lub khw thov nws; tsawg tsawg nyob muaj hnub nyob rau hauv thiab hnub tawm.
Lub Foundation: Nws pib nrog Casting
Koj tsis tuaj yeem tham txog qhov tseeb precision machining yam tsis tau pib ntws. Yog tias koj cov khoom nyoos yog cov khib nyiab, koj tsuas yog ua cov khib nyiab mus rau qhov tseeb heev. Qhov no yog qhov uas ntau cov khaub ncaws sib xyaw ua ke luv luv. Kuv tau pom zoo nkauj programmed CNC ua haujlwm puas los ntawm subsurface casting porosity uas tsuas yog tshwm sim ntawm qhov kawg ua tiav. Qhov ntawd yog qhov poob tag nrho. Qhov no yog vim li cas tus qauv ntawm lub tuam txhab nyiam Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) ua rau siab. Nrog 30 xyoo nyob rau hauv ob qho tib si casting thiab machining, lawv tau txais qhov txuas no intrinsically. Lawv qhov chaw pib yog lawv tus kheej qhov chaw ua haujlwm - plhaub pwm thiab peev casting. Los ntawm kev tswj cov txheej txheem casting, lawv tswj cov qauv ntawm cov nplej, cov khoom siv ncaj ncees, thiab cov nyiaj pib pib. Machining ib feem koj nrum koj tus kheej yog sib tham sib txawv; koj paub nws cov secrets, nws cov ntsiab lus kev ntxhov siab, qhov twg nws yuav tau shrunk me ntsis ntxiv. Qhov ntawd yog lub hauv paus kom zoo dua rau premier precision machining uas cov khw ua haujlwm dawb tsis muaj.
Siv lawv cov haujlwm nrog cov nickel-based alloys, piv txwv li. Cov ntaub ntawv no yog kev phem ntawm cov cuab yeej thiab nyiam warp. Yog hais tias lub casting tsis ntxhov siab-relieved kom zoo los ntawm kev mus-mus, tsis muaj ib tug npaum li cas ntawm zoo nkauj machining yuav cawm nws. QSY txoj hauv kev ntawm kev tuav tag nrho cov saw hlau, los ntawm cov hlau molten mus rau qhov tiav, txhais tau tias lawv tuaj yeem ci hauv kev ruaj ntseg los ntawm theem ib. Lawv tsis yog txiav hlau xwb; lawv tau tswj tag nrho lub neej voj voog ntawm lub workpiece ua ntej nws txawm tsoo lub txaj CNC. Qhov no tsis yog qhov txiaj ntsig theoretical - nws yog dab tsi tiv thaiv lub tshuab ua haujlwm zoo kawg nkaus los ntawm kev cuam tshuam tom qab nws rub tawm lub tshuab nqus tsev chuck.
Kuv nco qab txog qhov project rau marine twj impeller hauv duplex stainless hlau. Tus neeg siv khoom tuaj rau peb tom qab ob qhov kev sim ua tsis tiav rau lwm qhov.
