Ib tus neeg muag khoom German Tier 1 tau xa mus rau peb ob daim ntawv kho lub hli tas los. Ob tus neeg muag khoom hu ua lawv cov kev pabcuam "kev kho kom zoo dua qub." Ib tus nqi $4,800. Lwm tus hais txog $12,000.
Qhov $ 4,800 nqe lus hais tias tsis muaj kev sim hardness, tsis muaj vuam txheej txheem, tsis muaj qhov loj me. Tus nqi $12,000 tau teev tseglaser vuamnrog sib phim S136 muab tub lim, pov thawj rau ± 0.01mm, thiab 200,000-cycle warranty. Ib tus neeg muag khoom tau muag cov sijhawm ua haujlwm. Lwm tus yog muag ib qho kev kho kom zoo dua qub.
Pab neeg yuav khoom xaiv $4,800. Plaub lub hlis tom qab, kev kho tsis tau tiav ntawm 38,000 cycles. Re-kho ntxiv ntau lawm stoppage tshaj qhov $12,000 kev xaiv yuav raug nqi nrog warranty zoo.
Peb pom qhov txawv ntawm qhov no tsis tu ncua. Qhov teeb meem tsis yog tias cov neeg yuav khoom xaiv tsis zoo - nws yog cov pwm kho cov lus siv suab nrov thaum xa khoom sib txawv. Tsis muaj lub hauv paus rau kev sib piv cov nqe lus ntawm qhov tshwm sim ntau dua li cov lus piav qhia, koj tab tom muab cov txiv apples sib piv rau cov ntsiab lus tsis txaus ntseeg.
Cov ntaub ntawv German ntawd rov qab mus rau ib qho kev suav tsis tau hais txog: tus nqi ib lub voj voog ntxiv.
Cov pwm yog Class 102, ua rau 500,000 cycles, zaum ntawm 380,000 thaum pib kho. Qhov kev kho $4,800, nws tau tuav hla 120,000 qhov seem seem, yuav raug nqi $0.04 ib feem. Qhov kev xaiv $ 12,000 nrog warranty yuav raug nqi $ 0.06 ib feem. Tus tshiab $28,000 pwm amortized tshaj 500,000 cycles khiav $0.056 ib feem.
Qhov kev xaiv pheej yig tshaj rau ib feem yog qhov ua tsis tau tiav -tab sis tsuas yog tias nws tsis ua tiav. Tom qab rov- kho dua, tus nqi tiag tiag tau tshaj cov cuab yeej tshiab uas tsis muaj kev lav phib xaub mus tom ntej.
Yog tias koj daim ntawv kho mob tsis suav nrog cov ntawv tshaj tawm - kho lub voj voog lub neej kwv yees, koj tsis tuaj yeem suav tus nqi ib feem ntawm -. Koj tab tom pom zoo rau ib kab, tsis yog kev txiav txim siab peev. Nug tus lej. Yog tias tus neeg muag khoom tsis tuaj yeem muab tau, lawv tab tom hais txog kev ua haujlwm, tsis yog kho dua tshiab.
Qhov crossover point-qhov twg hloov kho kho- feem ntau yog nyob ib ncig ntawm 80% ntawm lub voj voog lub neej. Abrasive cov ntaub ntawv thawb nws mus rau 70%. Koj cov pwm ntawm 450,000 tawm tsam 500,000 qhov ntsuas yog nyob hauv thaj chaw sib txawv dua li koj cov pwm ntawm 300,000.
Tus neeg yuav khoom German kho qhov kev txiav txim siab muaj qhov teeb meem thib ob: lawv tau saib cov pwm puas thaum lawv tuaj yeem saib cov txheej txheem kev puas tsuaj tshwm sim los ntawm pwm.
Flash nyob ib ncig ntawm tag nrho cov cheeb tsam ib puag ncig feem ntau qhia tias clamping quab yuam los yog kev sib tw -ib qho teeb meem xovxwm. Kho qhov ntsuas tsis raug nqi dab tsi. Flash ntawm kev sib cais cov kab lus qhia qhia tias cov cuab yeej siv hauv zos yuav tsum tau kho. Flash nyob ib ncig ntawm ejector pins teeb liab hnav bores- hloov cov khoom, tsis yog qhov loj dua.
Misdiagnosis nkim nyiaj hauv ob qho tib si. Peb ntsib cov qauv no tsis tu ncua: qhov tsis zoo ntawm qhov chaw raug ntaus nqi los ntawm kab noj hniav thaum qhov tseeb ua rau degraded txias efficiency. Scale hauv cov cua txias channel tsim cov chaw kub uas ua rau muaj qhov tsis xws luag ua rau cov kab noj hniav hnav. Kev tshem tawm feem ntau daws qhov tshwm sim uas yuav tsum tau ua kom cov kab noj hniav rov ua dua - ntawm 15% ntawm tus nqi.
Ua ntej cog lus rau kev ua hauj lwm kab noj hniav, xyuas cov cua txias txaus tawm tsam thawj qhov tshwj xeeb. Yog tias ntws poob ntau dua 20%, descaling yog thawj qhov kev sim, tsis yog qhov kawg.
Cov ntaub ntawv German muaj lwm qhov tseem ceeb: tsis muaj cov ntsiab lus siv rau kev siv nyiaj txiag tsim nyog.
Raws li US Department of Energy tshawb fawb, txhua las hauv kev tiv thaiv kev saib xyuas rov qab kwv yees li tsib duas las hauv kev zam kev ua tsis tiav (eere.energy.gov). Kev lag luam benchmarks qhia txhua xyoo saib xyuas faib ntawm 3-5% ntawm pwm tus nqi rau cov cuab yeej yooj yim, 15-25% rau txoj kevkub khiav systems.
Koj li $45,000 16-kab noj hniav kub khiav nqa cov peev nyiaj kho mob qis dua $6,750 yog qhov tsis txaus ntseeg. Qhov sib txawv tsis ploj mus-nws hloov mus rau cov ntawv xa nyiaj kub ceev nrog 3-5x tus lej sib npaug thiab lub sijhawm tsis zoo.
Cov pwm German ntawd tsis muaj keeb kwm kev kho mob. Thawj "kho" yog qhov tseeb ncua kev txij nkawm. Thaum lub sij hawm kev puas tsuaj tau hais txog, cov khoom siv ntau dhau tau hla qhov chaw pib qhov kev kho sai.
Kev xaiv thev naus laus zis ua rau muaj txiaj ntsig ntau dua li pab pawg muag khoom paub.
FAW-Volkswagen tau sau tseg txog kev kho qhov tuag stamping: 10mm qhov chaw ntawm qhov tseem ceeb tsim. Siv ALM200 laser welding-0.4mm qhov chaw, 0.4mm hlau-technicians ua tiav qhov vuam hauv 30 feeb ntxiv rau 30 feeb ua tiav. Yield rov qab mus rau 99.8%. Tus nqi tuaj nyob rau hauv 85% qis dua ib txwm TIG mus kom ze (dowinlasers.com).
Qhov kom zoo dua yog localized tshav kub. Nrog laser vuam, niam txiv hlau nyob ntawm qhov kub thiab txias millimeters ntawm lub pas dej welding. Rauhigh kub cuab yeej steelsqhov twg hardness tseem ceeb-H13, S7, 420 stainless- tuav cov khoom kho cua sov txiav txim seb puas kho puas tau.
Thaum thov cov quotes, nug seb puas muaj peev xwm laser nyob hauv -tsev lossis subcontracted. Hauv -lub tsev txhais tau tias hloov pauv sai dua thiab tswj tau ncaj qha. Subcontracting ntxiv cov kauj ruam tuav. Tsis yog qhov tsis ncaj ncees lawm, tab sis koj yuav tsum paub qhov koj tab tom yuav.
Laser tsis yog universally zoo. Loj - thaj chaw puas tsuaj feem ntau ua sai dua nrog TIG. Aluminium teb tsis zoo rau cov txheej txheem laser. Lo lus nug tsis yog "koj puas muaj laser?" tab sis "rau qhov kev puas tsuaj ntawm cov hlau no, cov txheej txheem zoo li cas, thiab vim li cas?"
Kev kho RFQ yog qhov uas koj muaj leverage -thiab feem ntau cia nws tsis siv.
Ib qho RFQ tshwj xeeb tsuas yog "thov kho thiab hais lus" caw cov lus teb tsis sib xws. Txhua tus neeg muag khoom muaj peev xwm ua raws li lawv qhov kev xav.
Kev suav suav hloov kev sib tham los ntawm "qhov no yuav raug nqi dab tsi?" rau "qhov no puas ua rau kev txiav txim siab nyiaj txiag ntawm qhov cuab yeej no lub neej?" Tus neeg muag khoom pom 450,000 lub voj voog tawm tsam 500,000 qhov ntsuas yuav tsum qhia seb qhov kho puas yog suab zoo- tsis yog vim lawv muaj kev siab dawb, tab sis vim hais tias kev pom zoo ua haujlwm tsis ua rau muaj kev ntseeg siab.
Cov ntaub ntawv qib tiv thaiv hom tsis ua haujlwm feem ntau: muab tub lim incompatibility. P20 puag welded nrog H13 muab tub lim tsim hardness mismatch uas accelerates hnav ntawm qhov kho ciam teb.
Ib qho kev sib txawv ntxiv los ntawm cov ntaub ntawv German: seb puas yuav tawm los yog tsim kom muaj peev xwm sab hauv.
Kev khiav hauj lwm khiav tsawg dua 10-15 cov pwm nquag ua haujlwm tsis tshua pom zoo rau sab hauv kho muaj peev xwmkev loj hlob. Khoom siv ib leeg- precision grinder, laser welder, EDM- khiav $150,000+ ua ntej kev cob qhia thiab chaw. Nyob rau hauv tas li ntawd, lub peev yuav muaj ntau outsourced peev xwm.
Tshaj 15 pwm nrog cov nqi nres ntau tshaj $20,000/hnub, hauv -lub tsev feem ntau them los ntawm lub sijhawm teb. Ib qho pwm kho thaum hmo ntuj rov qab los rau tag kis. Tib txoj hauj lwm outsourced yuav tsum tau thauj ob qho tib si cov lus qhia ntxiv rau lub sij hawm queue ntawm cov chaw muag khoom.
Cov hybrid uas ua haujlwm rau nruab nrab- kev ua haujlwm teev: muaj peev xwm sab hauv rau kev saib xyuas niaj hnub- ntxuav, hloov tus pin, polishing- nrog cov neeg muag khoom kev sib raug zoo rauprecision ua haujlwm zoo li laser vuam lossis loj reconditioning. Ceev kom zoo dua ntawm kev cuam tshuam ntau zaus, tsis muaj peev txheej hauv cov cuab yeej tshwj xeeb siv ob zaug hauv ib xyoos.
Tus thawj coj saib xyuas kev muag khoom hauv German tau rov tsim nws cov txheej txheem RFQ nkaus. Cov qauv tam sim no suav nrog suav suav, qib steel, qhov ntev kam rau ua, qhia meej txog kev kwv yees lub neej thov. Cov neeg muag khoom qhia cov txheej txheem, muab tub lim compatibility, thiab kev sib piv cov ntaub ntawv kho.
Tus naj npawb ntawm cov neeg muag khoom uas teb tau poob los ntawm kwv yees li ib nrab. Teb zoo tau zoo heev. Qhov feem pua ntawm kev kho tuav los ntawm kev ntsuas lub neej tau nce. Kev siv nyiaj kho tag nrho thoob plaws nws chav cuab yeej tau txo qis -tsis yog vim tias ib tus neeg ua haujlwm tau pheej yig dua, tab sis vim tias tsawg dua txoj haujlwm ua tsis tiav thiab yuav tsum tau ua haujlwm dua -.
Tam sim no nws pab neeg ua haujlwm yooj yim kev txiav txim siab ua ntej kev pom zoo kho: Dab tsi yog ib feem ntawm - tus nqi ntawm qhov kev kho no thoob plaws lub neej ntawm cov cuab yeej? Yuav ua li cas rau tus nqi ntawd yog tias qhov kho tsis tuav? Puas yog cov qauv kev puas tsuaj zoo ib yam nrog kev hnav, lossis nws puas qhia txog cov txheej txheem uas kho yuav tsis daws tau?
Peb cov lus nug no nthuav tawm feem ntau ntawm cov ntaub ntawv sib txawv uas ua rau nws qhov yuam kev $4,800 qub. Cov lus teb tsis yog ib txwm pom tseeb. Tab sis nug lawv ua ntej cog lus nyiaj txiag hloov kev sib tham los ntawm "qhov kev tsocai no puas siv tau?" rau "yog qhov kev nqis peev no?"
Ntawm ABIS, peb pom ob sab ntawm qhov sib npaug no. Peb tsim cov pwm uas thaum kawg yuav tsum tau kho, thiab peb ntsuas qhov kev txiav txim siab kho ntawm cov pwm uas peb tsis tau tsim. Cov qauv kev ua tsis tiav yog zoo ib yam: teeb meem pawg ntawm cov lus hais nyob ib ncig ntawm cov ntaub ntawv tsis tiav, tsis nyob ib puag ncig kev ua haujlwm tsis zoo lossis kev xav phem.
Tus neeg yuav khoom German tau them tus nqi kawm ntawv peb tau saib dua nyob rau ntau lub cuab yeej chav: qhov kev kho cov lus hais uas zoo li pheej yig tshaj yog feem ntau yog ib qho uas muaj qhov tsis meej tshaj plaws. Qhov tsis meej pem tsis yog phem - nws yog qhov tshwm sim ntawm cov neeg muag khoom teb cov lus nug sib txawv thaum lawv tau txais cov lus qhia tsis tiav.
Yog tias koj muaj ib daim ntawv kho mob ntawm koj lub rooj thiab qhov tsis meej - lossis yog tias koj tsis paub tseeb tias kev kho puas ua rau muaj kev nkag siab ntawm qhov no hauv lub neej cuab yeej - xa peb yam koj muaj. Qib steel, txhaj tshuaj suav, cov duab puas yog muaj. Peb yuav qhia rau koj seb qhov kev tsocai hais txog qhov xav tau tiag tiag, cov lus nug dab tsi los thawb rov qab mus rau tus neeg muag khoom, thiab seb qhov peev txheej lej ua haujlwm ntawm kev suav tam sim no.
Qhov kev ntsuas ntawd tsis muaj nqi dab tsi. Tau txais cov ntaub ntawv raug cai ua ntej yuav nqis peev nyiaj, raws li tus neeg yuav khoom German tau kawm, tseem ceeb tshaj li kev txuag ntawm kev kho nws tus kheej.
