Koj paub, thaum cov neeg feem coob hnov 'CNC machining', lawv daim duab pristine, automated Rhiav qhov twg koj pub rau hauv CAD qauv thiab zoo meej qhov chaw cia li pop tawm. Qhov ntawd yog glossy daim ntawv qhia version. Qhov tseeb, qhov koj tsuas yog kawm los ntawm kev khiav haujlwm thiab tuav cov khoom tiav hauv koj txhais tes, yog kev sib tham tas li ntawm qhov zoo tshaj plaws digital thiab lub ntiaj teb lub cev ntawm cov hlau. Nws tsis yog hais txog programming xwb; Nws yog hais txog kev paub yuav ua li cas ib pawg tshwj xeeb ntawm 316L stainless yuav coj tus cwj pwm nyob rau hauv lub cuab yeej tshiab, lossis yog vim li cas qhov zoo nkauj, kev tsim qauv yuav sib tham zoo li vwm tshwj tsis yog tias koj txhawb nws hauv txoj kev tshwj xeeb, tsis pom tseeb. Qhov sib txawv ntawm qhov screen thiab swarf yog qhov chaw ua haujlwm tiag tiag.
Lub Foundation: Nws pib nrog cov khoom, tsis yog Code
Kuv tsis tuaj yeem ntxhov siab qhov no txaus. Koj G-code tsuas yog zoo li koj nkag siab txog cov khoom koj txiav. Peb pom nws txhua lub sijhawm - tus neeg siv khoom xa cov qauv tsim kom zoo rau txhuas thiab xav kom nws ua hauv Inconel 718 vim tias nws yuav tsum tau tiv taus siab kub. Ntawm qhov screen, nws yog tib cov ntaub ntawv. Nyob rau hauv pem teb khw, nws yog ib tug tsiaj nyaum txawv kiag li. Cov kev txiav txim siab, kev xaiv cov cuab yeej, txawm tias lub tshuab rigidity yuav tsum hloov pauv loj heev.
Qhov no yog qhov chaw tsim khoom-machining combo ua haujlwm, zoo li ib qho ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., (koj tuaj yeem tshawb xyuas lawv cov peev txheej ntawm https://www.tsingtaocnc.com), muaj qhov zoo zais cia. Lawv twb nyob rau hauv casting thiab CNC machining rau xyoo lawm. Thaum lawv tau txais ib qho casting uas xav tau kev ua tiav, lawv twb paub cov qauv ntawm cov nplej, qhov muaj peev xwm nyuaj me ntsis los ntawm cov txheej txheem txias, qhov seem ntawm kev ntxhov siab. Qhov ntawd yog intel koj tsis tau txais los ntawm cov ntaub ntawv pov thawj. Nws txhais tau tias lawv tuaj yeem npaj cov txheej txheem machining ua haujlwm nrog cov ntaub ntawv keeb kwm, tsis tawm tsam nws. Sim ua lub tshuab ua lag luam nyuaj uas tsis muaj keeb kwm yav dhau los zoo li kev taug kev hauv qhov tsaus ntuj.
Piv txwv li, nrog nickel-based alloys lawv hais txog - cov khoom zoo heev, tab sis npau suav phem rau lub neej yog tias koj kho lawv zoo li hlau. Cov khoom ua haujlwm-hardens thaum koj txiav. Yog li koj tsis tuaj yeem cia lub cuab yeej rub; koj xav tau ib tug zoo rake, ntse npoo, thiab koj yuav tsum muaj ib tug tas li, nruj txaus pub kom tau nyob rau hauv uas ua hauj lwm-hardened txheej. Nres lossis qeeb hauv nruab nrab ntawm kev txiav? Koj nyuam qhuav tsim ib qho chaw hauv zos uas yuav rhuav tshem koj qhov kev hla dhau mus. Nws yog ib tug seev cev ntawm siab thiab precision.
Txoj hauj lwm yooj yim uas tsis yog: Ib Daim Phaj Ncaj Ncees Saga
Cia kuv muab piv txwv yooj yim rau koj uas mus rau sab. Cov neeg siv khoom xav tau ib lub phaj loj, tuab ntawm cov hlau me me, tsuas yog qee qhov los ntawm qhov thiab lub hnab milled. Yooj yim nyiaj, txoj cai? Peb muab lub phaj, clamped nws, thiab pib tig. Ua tiav thawj sab, tig nws, thiab pib ntawm qhov thib ob. Thaum ntawd yog thaum npau suav phem pib. Lub phaj, nyob rau hauv kev ntxhov siab ntawm thawj zaug txiav, tso tawm sab hauv kev ntxhov siab thiab warped. Phem. Thaum lub sij hawm peb ua tiav lub ntsej muag thib ob, ib feem yog txiv tsawb-puab, tawm ntawm kev kam rau siab los ntawm mais.
Qhov tsis ua tiav yog xav tias cov khoom siv raw ruaj khov. Rau txoj haujlwm flatness tseem ceeb, koj feem ntau yuav tsum tau siv lub tshuab ntxhib, ces cia nws zaum (kev ntxhov siab), tom qab ntawd ua tiav tshuab. Tej zaum koj tseem yuav tau ua ob zaug. Nws yog ib zaj lus qhia ntawm kev ua siab ntev thiab txheej txheem. Tam sim no, thaum kuv saib daim duab kos duab yooj yim, kuv xav txog cov khoom hauv paus, nws thickness, nws cov keeb kwm thermal. Qhov ntawd yog hom kev ua tau zoo, tsis muaj kev xav pom tseeb uas cais cov khoom sib tsoo los ntawm tus khub machining. Lub khw nrog cov khoom siv sib sib zog nqus, zoo li QSY nrog lawv cov keeb kwm yav dhau los 30 xyoo, yuav muaj cov txheej txheem no ci rau hauv lawv cov haujlwm ua haujlwm rau cam khwb cia thiab forged blanks, zam cov nqi rov ua dua.
Tooling tsis yog hais txog lub hom
Txhua leej txhua tus xav tham txog qhov tseeb, zoo tshaj plaws kawg zeb los ntawm lub npe saum toj kawg nkaus. Thiab tseeb, cov cuab yeej zoo tseem ceeb. Tab sis qhov tseem ceeb tshaj yog kev teeb tsa. Kuv tau pom $ 200 kawg zeb snap vim qhov me me ntawm kev khiav tawm hauv cov khoom pheej yig, thaum lub cuab yeej nruab nrab hauv qhov zoo kawg nkaus tuned, cov neeg ua haujlwm siab ua haujlwm tau ntau teev. Tag nrho cov system - spindle, tuav, collet, cuab yeej - yuav tsum tau suav hais tias yog ib qho. Vibration yog tus yeeb ncuab ntawm kev ua tiav thiab lub neej cuab yeej.
Rau cov khoom siv tawv tawv, peb feem ntau siv cov cuab yeej carbide, tab sis qee zaum zoo, ntse cobalt HSS cov cuab yeej nrog lub zog geometry tuaj yeem muaj sia nyob zoo dua nyob rau hauv ib qho kev sib tshuam los ntawm kev sib tsoo nrog cov khoom tsis sib xws. Nws tsis yog ib txwm hais txog qhov nyuaj tshaj plaws substrate; nws yog hais txog cov cuab yeej zoo rau kev txiav. Lawv ua hauj lwm nrog plhaub pwm thiab peev castings txhais tau hais tias lawv nyob nraum tas li cuam tshuam nrog qhov sib txawv ntawm qhov chaw pib, yog li cov cuab yeej siv no yog qhov thib ob rau lawv.
Precision yog txheej txheem, tsis yog qhov chaw
Koj hu rau qhov kam rau ua ntawm +/- 0.01mm ntawm lub tshuab. Puas yog qhov ntawd txhais tau hais tias ib feem yuav ua siab ntev? Tsis tas li. Thermal expansion yog qhov tseeb. Ib feem machined thaum sawv ntxov thaum lub khw yog 18 ° C yuav ntsuas txawv thaum tav su ntawm 24 ° C, tshwj xeeb tshaj yog nrog txhuas. Peb tau kawm kom cia qhov chaw normalize rau hauv chav kuaj ntsuas kub ua ntej ntsuas zaum kawg. Rau kev ua haujlwm tshwj xeeb, koj tswj hwm qhov chaw ib puag ncig, qhov txias txias, txhua yam.
Qhov no txuas mus rau fixturing. Qhov zoo nkauj machined feature tsuas yog raws li qhov tseeb raws li lub vise lossis fixture tuav qhov. Peb ib zaug scrapped ib pawg vim hais tias lub puab tsaig hnav-tawm lub puab tsaig muaj ob peb microns ntawm qaij peb tsis tau ntes. Tam sim no, qhia txog kev teeb tsa yog kev ntseeg, tsis yog kev tawm tswv yim. Rau ib lub tuam txhab machining siab-kev ncaj ncees castings rau ntau yam lag luam, cov txheej txheem kev qhuab qhia yog tsis-negotiable. Qhov tsis zoo ntawm lub twj tso kua mis los yog lub cev lub cev tsis yog qhov tsis lees paub xwb; nws yog ib qho kev ua tsis tiav.
Thiab hais txog kev ntsuas, kev ntseeg siab caliper muaj nws qhov txwv. Rau qhov tseeb txoj hauj lwm tolerances los yog complex contours, koj xav tau ntau dua. CMMs, optical scanners - lawv tau dhau los ua ib feem ntawm kev tawm tswv yim machining voj. Cov ntaub ntawv qhia rau koj yog tias koj cov txheej txheem drifting. Nws yog qhov kaw-voj ntawm lub tshuab, ntsuas, kho uas tsim kom muaj qhov sib xws.
Thaum Tsim Raws Li Kev Tsim Khoom
Qhov no yog qhov loj tshaj ntawm kev sib txhuam thiab lub sijhawm. Engineers tsim rau kev ua haujlwm, uas yog qhov tseeb. Tab sis qee zaum lub vojvoog me me ntxiv, lossis kev ua siab ntev rau ntawm lub ntsej muag tsis tseem ceeb, tuaj yeem txiav lub sijhawm ua haujlwm thiab raug nqi los ntawm 30% nrog xoom cuam tshuam rau kev ua haujlwm. Cov haujlwm zoo tshaj plaws tshwm sim thaum muaj kev sib tham ua ntej qhov kev kos duab zaum kawg yog khov.
Ib qho classic yog qhov sib sib zog nqus hnab ris nrog lub kaum sab xis me me. Tus tsim qauv xav tau lub ntse ntse 1mm sab hauv ces kaum. Qhov ntawd xav tau 2mm kawg zeb. Yuav zeb 50mm sib sib zog nqus hnab tshos nrog ib tug 2mm cuab tam? Koj tab tom saib ntau, ntau qhov qeeb qeeb, cov cuab yeej loj deflection, thiab tej zaum yuav tawg. Kev tawm tswv yim txog 2.5mm lossis txawm tias 3mm radius tso cai rau lub cuab yeej muaj zog dua, pub nrawm dua, thiab cov txheej txheem txhim khu kev qha. Nws tsis yog kev sib haum xeeb; nws yog optimization rau kev muaj tiag.
Ua hauj lwm nrog pre-cast Cheebtsam ntxiv lwm txheej. Cov CNC machining daim ntawv qhia txog kev nqis peev-ntxuav yog tsis pib los ntawm cov khoom thaiv; nws pib los ntawm daim ntawv ze-net-zoo li. Tus kws kho tshuab txoj haujlwm yog txhawm rau ntaus cov ntaub ntawv tseem ceeb thiab qhov chaw, feem ntau ua haujlwm nrog cov nyiaj tsis sib xws. Qhov no yuav tsum muaj qhov sib txawv ntawm qhov programming - feem ntau siv cov voj voog kev sojntsuam txhawm rau nrhiav qhov casting qhov tseeb hauv qhov chaw es tsis xav tias nws yog qhov zoo sib xws. Nws yog hybrid ntawm precision machining thiab txawj haum.
Tus nqi tsis pom: Kev sib npaug ntawm qhov ntsuas
Leej twg tuaj yeem ua tau ib feem zoo. Ua qhov 1000th qhov zoo ib yam rau thawj zaug yog qhov kev sib tw tiag tiag ntawm CNC machining. Qhov no yog qhov uas cov ntaub ntawv txheej txheem, cuab yeej tswj lub neej, thiab kev kuaj xyuas hauv cov txheej txheem tuaj. Nws yog qhov ua haujlwm tsis txaus ntseeg. Cov cuab yeej teev teev teev tseg, teem caij tiv thaiv kev saib xyuas ntawm cov cav tov, muaj cov lus qhia meej rau cov neeg ua haujlwm.
Rau ib tus neeg muag khoom zoo li QSY, uas nws lub lag luam tau tsim los ntawm kev muab cov khoom siv los ua kom ntseeg tau, lub pob txha ua haujlwm no yog txhua yam. Lawv cov keeb kwm ntev qhia tias lawv yuav tsum tau daws cov teeb meem kev ntsuas no rau cov neeg siv khoom thoob plaws kev lag luam, los ntawm ib qho qauv mus rau kev tsim khoom. Lub tuam txhab kev paub txog yuav ua li cas thiaj li tswj tau qhov zoo ntawm cov khoom sib txawv ntawm cov castings yog ib qho khoom muaj nqis uas koj tsis tuaj yeem rub tawm lossis yuav tawm ntawm lub txee.
Yog li, thaum kuv xav txog CNC, Kuv tsis txaus siab los ntawm lub tshuab 5-axis flashy (txawm hais tias lawv yog cov cuab yeej zoo kawg nkaus), thiab xav paub ntau dua nyob rau hauv lub ntsiag to, grittier ecosystem nyob ib ncig ntawm nws: cov khoom siv science, fixture tsim, kev ntsuas nruj, thiab nyuaj-yeej zaj lus qhia los ntawm cov hauj lwm uas tsis mus rau txoj kev npaj. Qhov ntawd yog qhov hloov pauv cov ntaub ntawv digital mus rau qhov kev cia siab, lub cev tiv thaiv. Nws yog ib qho khoom siv tes ua uas hnav cov khaub ncaws ntawm automation.
