Raws li tus kws tshaj lij kev lag luam luam yeeb ntim tshuab qhov chaw, Hansheng Automation khav theeb nws tus kheej CNC machining chaw, khav theeb qhov tseeb ntawm ± 0.002mm, ua tiav super- daim iav- zoo li tiav. Tom ntej no, kuv mam li tshawb txog tooj liab, cov khoom siv rau CNC machining, kos duab ntawm peb tus kheej machining xyaum.
tooj liab yog dab tsi?
Yuav kom nkag siab tias tooj liab yog dab tsi, peb yuav tsum xub teb cov lus nug, "Cov khoom siv tooj liab yog dab tsi?" Tooj liab yog ib qho tshwm sim, cov hlau hloov pauv nrog cov cim tshuaj Cu (los ntawm Latin "cuprum") thiab tus lej atomic 29. Nws yog ib qho ntawm ob peb yam khoom uas tuaj yeem muaj nyob hauv ib lub xeev hlau thiab yog ib qho ntawm cov hlau siv los ntawm tib neeg.
Hom tooj liab muaj dab tsi?
Tooj tsis yog ib hom khoom siv; Hloov chaw, nws tau muab faib ua ob pawg: ntshiab tooj liab thiab tooj liab alloys. Txhua hom muaj kev ua tau zoo tshaj plaws rau cov kev xav tau ntawm CNC machining.
Ntshiab tooj liab
This type of copper has a purity of ≥99.5%. The most commonly used grade in CNC machining is C110 electrolytic tough pitch copper, which boasts a purity of up to 99.9%. It exhibits excellent electrical conductivity (101.5% IACS, second only to silver), thermal conductivity (391 W/m-K), and ductility (elongation >45%, ua kom kos duab rau hauv ultra- cov xov hlau nyias nyias li 0.01mm). Thaum CNC machining ntshiab tooj liab, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov nws cov viscosity siab, yuav tsum tau tshwj xeeb cov cuab yeej geometry (xws li lub cuab yeej rake lub kaum sab xis siab dua los yog sib npaug li 25 degree) thiab TiAlN txheej los tiv thaiv kev tsim - nce ntug.
Tooj Alloys
Hom tooj liab no feem ntau yog tsim los ntawm kev ntxiv cov khoom xws li zinc, tin, thiab ua rau cov tooj liab ntshiab, txhim kho nws lub zog thiab kev ua haujlwm. Cov hom muaj xws li:
Brass: tooj liab-zinc alloy (5%-45% zinc ntsiab lus). C360 tooj dag (muaj 2.5%-3.7% txhuas) yog tus qauv siv dawb- txiav cov khoom tooj liab. Nws qhov ntsuas kev txiav yog ua raws li 100% ntawm 1214 dawb-txiav steel. Nws lub zog txiav yog 40% qis dua cov tooj liab ntshiab, thiab nws lub cuab yeej lub neej yog peb zaug ntev dua, ua rau nws yog cov khoom siv tooj liab zoo tshaj plaws rau CNC machining ntau zaus.
Bronze: Ib qho tooj liab- tin alloy nrog cov txiaj ntsig zoo rau kev tiv thaiv corrosion (tshwj xeeb tshaj yog dej hiav txwv tsis kam) thiab hnav tsis kam, ua rau nws tsim nyog rau kev ua haujlwm marine engineering xws li cov kiv cua bushings.
Oxygen-Free Copper (OFC): Nrog rau kev purity ntau dua lossis sib npaug li 99.99% thiab cov ntsiab lus tsis tshua muaj oxygen, nws tsim nyog rau siab - CNC qhov chaw (xws li lub tshuab nqus tsev hluav taws xob). Txawm tias cov kab impurities tuaj yeem cuam tshuam nws qhov kev ua tau zoo.
High-lub zog alloys: xws li C194 tooj liab- hlau-phosphorus alloy thiab C195 tooj liab- hlau-zinc alloy, txhim kho tensile lub zog thaum tswj kev ua haujlwm siab (Ntau dua lossis sib npaug rau 85% ntawm cov tooj liab ntshiab), ua kom cov khoom siv hluav taws xob tsawg tsawg.

Cov khoom siv tooj liab puas muaj kev nyab xeeb?
Cov khoom siv tooj liab muaj kev nyab xeeb thaum siv kom raug thiab nrog kev ceev faj tsim nyog, ob qho tib si thaum CNC machining thiab hauv nws daim ntawv thov zaum kawg.
Machining kev nyab xeeb
Hluav taws xob conductivity Risk: tooj liab yog hluav taws xob conductive. Xyuas kom cov khoom siv CNC yog hauv av kom zoo los tiv thaiv hluav taws xob thaum lub tshuab ua haujlwm.
Txiav Fluid Protection: Sulfur- muaj cov kua txiav yog feem ntau siv thaum ua cov tooj liab ntshiab. Cov neeg ua haujlwm yuav tsum hnav cov hnab looj tes kom tsis txhob muaj kev sib cuag ntawm daim tawv nqaij ncaj qha thiab ua kom muaj cua zoo hauv qhov chaw ua haujlwm kom tsis txhob nqus cov khoom tsis haum.
Kev Nyab Xeeb Kev Nyab Xeeb
Antimicrobial Advantage: Tooj liab muaj cov khoom siv tshuaj tua kab mob. Cov khoom siv kho mob tau ua los ntawm tooj liab los ntawm kev ua CNC pab txo cov kab mob microbial - kev pheej hmoo kis kab mob, ua haujlwm zoo dua cov khoom yas.
Kev txwv kev siv: tooj liab feem ntau tsis tsim nyog rau cov ntim khoom noj ncaj qha (piv txwv li, tsis muaj coated) vim muaj kev phom sij los ntawm kev noj ntau dhau. Rau cov khoom siv dej uas siv tau, cov khoom siv tooj liab nrog cov khoom noj - qib txheej yuav tsum raug xaiv.
FAQ
Q: Dab tsi yog cov cuab yeej txiav thiab cov tsis pom zoo rau CNC machining ntawm cov tooj liab ntshiab thiab C360 tooj dag?
A: Rau cov tooj liab ntshiab, vim nws cov nplaum siab, xaiv cov cuab yeej nrog lub kaum sab xis sab xub ntiag Loj dua lossis sib npaug li 25℃ua ke nrog TiAlN txheej. Siv cov kua txiav uas muaj sulfide additives los tiv thaiv kev tsim - nce ntug. Rau C360 tooj dag- feem ntau CNC- siv cov khoom siv tooj liab- cov cuab yeej txheem carbide txaus. Nyob rau hauv qhuav txiav tej yam kev mob, nto roughness tuaj yeem ncav cuag Ra 0.8μm, nrog rau cov nqi pub khoom noj tau ntawm ob zaug ntawm cov tooj liab ntshiab.
Q: Vim li cas tooj liab alloys (xws li tooj dag) tawg yooj yim thaum vuam? Yuav tiv thaiv qhov no li cas?
A: Kev tawg feem ntau tshwm sim los ntawm qis - boiling - cov ntsiab lus (zinc / lead) nyob rau hauv tooj liab alloys vaporizing thaum vuam, ua rau porosity nyob rau hauv lub vuam. Kev tiv thaiv txoj hauv kev: Rau tooj dag vuam, siv TIG vuam nrog ua ntej -tsim silicon bronze hlau (ERCuSi-A). Rau cov ntshiab tooj liab vuam, preheat lub hauv paus khoom rau 400℃thiab siv phosphorus -deoxidized tooj liab electrodes (ECu). Nrog rau kev ua kom zoo, kev sib koom ua ke tuaj yeem ncav cuag 90% ntawm cov khoom siv hauv paus.
Q: Yuav ua li cas deg oxidation thiab blackening zoo tiv thaiv ntawm CNC -machined ntshiab tooj liab qhov chaw?
A: Ua raws li peb - txheej txheem tiv thaiv:
① Ultrasonic tu kom tshem tawm cov kua dej;
② Chromate los yog benzotriazole passivation los ua ib zaj duab xis tiv thaiv (~ 0.5μm);
③ Nqus ntim.
Q: C360 tooj dag puas tuaj yeem hloov cov tooj liab ntshiab rau siab -cov khoom siv hluav taws xob muaj tseeb (piv txwv li, siab- cov khoom txuas tam sim no)?
A: No. Pure copper's conductivity (101.5% IACS) far exceeds C360 brass (25% IACS). Brass exhibits significantly higher temperature rise under high currents (>50A) thiab tsuas yog tsim nyog rau qis - daim ntawv thov teeb liab tam sim no (<1A) to reduce costs.
Q: Cov ncej dab tsi - yuav tsum tau ua rau cov khoom siv tooj liab siv nyob rau hauv marine ib puag ncig kom ntseeg tau tias muaj zog?
A: Brass nrog nto passivation yog qhov nyiam xaiv. Cov zinc-raws li oxide zaj duab xis nws cov ntaub ntawv tuaj yeem tiv taus ntau tshaj 1000 teev ntawm kev ntsuas ntsev tsuag. Yog tias siv tooj liab ntshiab, ntxiv nickel plating yuav tsum ua kom tiav qhov kev ua tau zoo, tab sis qhov no nce tus nqi los ntawm 30%.
