Thaum koj hnov ib lub npe zoo li 'Advanced Precision Machining Inc,' nws conjures ib daim duab tshwj xeeb, puas yog? Spotless floors, kab ntawm gleaming tsib-axis tshuab humming deb, thiab kam rau ua ntsuas hauv microns. Qhov ntawd yog qhov zoo tshaj plaws kev lag luam. Qhov tseeb, kev sib tsoo txhua hnub, yog messier, ntau nuanced, thiab frankly, nthuav ntau dua. Lo lus 'advanced' tau cuam tshuam ntau heev nws poob nws ntug. Nws tsis yog hais txog kev muaj Mori Seiki lossis DMG; nws yog hais txog dab tsi koj ua nrog nws thaum luam ntawv hu rau ib tug cobalt-raws li alloy ib feem nrog ib tug nyias-wall seem thiab sab hauv. Qhov ntawd yog qhov kev sim tiag tiag pib, thiab qhov twg ntau lub khw uas nyuam qhuav yuav daim paib pom tias lawv tsis yog 'siab tshaj' raws li lawv xav.
Advanced Misconception thiab Material Reality
Cia peb tham cov ntaub ntawv ua ntej, vim hais tias yog qhov chaw precision txawm nyob los yog tuag. Leej twg tuaj yeem ua tau txhuas. Qhov kev sib tw, thiab dab tsi cais lub khw ua haujlwm los ntawm qhov tseeb advanced precision machining tus khub, yog tuav cov khoom nyuaj. Xav tias cam khwb cia hlau rau lub hauv paus hnyav uas muaj kev vibration damping tseem ceeb, los yog 316 stainless rau corrosive ib puag ncig. Tab sis qhov kev ua si tiag tiag yog nyob rau hauv cov alloys tshwj xeeb. Kuv tab tom tham txog Inconel, Hastelloy, cobalt-chrome. Cov no tsis yog 'nyuaj' hlau xwb; lawv coj txawv txawv. Lawv ua hauj lwm-harden tam sim ntawd, lawv ua phem rau cov cuab yeej, thiab lawv xav tau ib tug symphony ntawm qhov tseeb speeds, pub, coolant siab, thiab cov cuab yeej txoj kev zoo. Ib lub khw thov advanced precision machining Lub peev xwm yuav tsum muaj qhov symphony down pat, tsis yog rau ib-tawm prototypes tab sis rau kev ua haujlwm zoo ib yam.
Qhov no yog qhov uas koj pom kev sib faib meej. Kuv nco qab kev ntsuas tus neeg muag khoom ob peb xyoos rov qab rau cov khoom siv nickel-alloy sensor vaj tsev. Lawv muaj cov tshuab tshiab, paub meej. Tab sis lawv cov txheej txheem yog kwv yees. Lawv tau hlawv los ntawm $ 200 kawg zeb hauv ob qhov chaw, lawv qhov chaw ua tiav tsis sib xws, thiab thermal distortion yog kev sib ntaus sib tua tas li. Lawv muaj cov cuab yeej kho vajtse, tab sis tsis yog cov ntaub ntawv, yuav luag intuitive paub. Sib piv nrog cov haujlwm uas tau loj hlob nrog cov ntaub ntawv tshawb fawb, zoo li pab pawg dhau ntawm Qingdao Qiangsenyuan Technology (QSY). Thaum koj tau nyob hauv casting thiab tshuab rau ntau tshaj 30 xyoo, raws li lawv muaj, koj tsim kev xav rau nws. Koj paub yuav ua li cas cobalt-raws li alloy yuav txav tom qab koj txiav nws, yuav ua li cas rau theem ua haujlwm los tswj kev ntxhov siab. Qhov ntawd yog advanced. Nws yog nyob rau hauv pab pawg neeg paub, tsis yog daim ntawv spec.
Qhov sib txuas ntawm casting thiab machining yog lwm qhov tsis zoo ntawm qhov tseeb precision. Ntau precision machining inc kev khiav hauj lwm nyiam pib nrog billet Tshuag. Nws yog kwv yees. Tab sis rau cov geometry nyuaj, pib nrog ze-net-puab casting-zoo li lub plhaub lossis peev castings QSY tshwj xeeb hauv- tuaj yeem yog txoj hauv kev ntse dua. Qhov ua kom yuam kev, thiab nws yog ib qho tseem ceeb, yog lub machining prep thiab nkag siab txog qhov casting qhov tsim qauv. Koj tsis tuaj yeem cia li clamp ib qho raw casting thiab mus. Koj xav tau datum nto, koj yuav tsum tau account rau tej yam porosity nyob rau hauv koj cov cuab yeej txoj kev, koj yuav tsum to taub cov nyhuv ntawm daim tawv nqaij. Tau txais txoj cai no yuav tsum muaj kev sib koom tes sib sib zog nqus ntawm qhov chaw tsim khoom thiab lub khw muag khoom, ib yam dab tsi uas tau hloov kho thaum ob lub peev xwm nyob hauv ib lub ru tsev.
Precision raws li ib tug txheej txheem, Tsis yog ib lub caij
Precision tsis yog ib qho kev ntsuas ntawm CMM daim ntawv qhia. Nws yog txheej txheem uas pib ntawm qhov kev tsocai thiab xaus ntawm kev xa khoom. Kuv tau pom cov khoom zoo nkauj tau muab pov tseg vim qhov kev tshuaj ntsuam xyuas yog qhov kev xav tom qab. Rau qhov tseeb advanced precision machining kev khiav hauj lwm, metrology yog kev koom ua ke. Nws tsis yog qhov kev kuaj zaum kawg nkaus xwb; nws yog nyob rau hauv-txoj kev. Kev soj ntsuam niaj hnub, kev soj ntsuam cov cuab yeej siv, SPC cov ntaub ntawv sau rau ntawm qhov loj me. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov khoom uas yuav tsum tau sib sau ua ke. Ib qho zoo meej uas tsis sib haum nrog nws tus khub yog tsis muaj txiaj ntsig.
Ib qho tsis ua hauj lwm uas nrog kuv yog ib pawg ntawm stainless hlau valve lub cev. Cov bores tau mus rau ib tug nruj concentricity callout. Peb tshuab lawv zoo kawg nkaus—los yog peb xav. CMM tau qhia txhua yam hauv spec. Tab sis thaum sib dhos, lawv khi. Qhov teeb meem? Peb ntsuas hauv chav ntsuas kub, tab sis cov khoom tau sib sau ua ke ntawm lub khw hauv pem teb uas yog 10 degrees sov dua. Lub thermal expansion sib txawv ntawm cov stainless yog txaus los ua cuam tshuam. Ib qho yuam kev rookie, tab sis ib qho uas raug nqi ib lub lim tiam kev tsim khoom. Nws qhia kuv tias 'precision' suav nrog cov saw ib puag ncig ntawm kev saib xyuas. Tam sim no, rau cov rooj sib txoos tseem ceeb, peb qhia tsis yog qhov ntsuas ntsuas xwb, tab sis kev sib dhos temp ntau. Qhov ntawd yog theem ntawm kev nthuav dav uas tseem ceeb.
Txoj kev xav no txuas ntxiv mus rau fixturing. Rau qhov ntim siab precision machining, koj fixture tseem ceeb npaum li koj cutter. Tsim ib lub fixture uas nrhiav tawm cov yam ntxwv cam khwb cia, muab kev sib txuas clamping quab yuam yam tsis muaj kev cuam tshuam, thiab tso cai rau kev thauj khoom / tshem tawm tau zoo yog kev kos duab. Nws tsis yog glamorous, tab sis ib tug tsis zoo tsim fixture yuav lav variability, txawm li cas 'advanced' koj zeb yog.
Qhov Tseem Ceeb CNC: Nws yog hais txog Programmer, tsis yog lub tshuab xwb
CNC yog lub nraub qaum, tab sis nws yog ib qho ntsiag to, ruam qaum tsis muaj lub siab zoo tom qab nws. Qhov sib txawv ntawm qhov zoo thiab qhov zoo feem ntau zaum hauv CAM software. Cov cuab yeej txoj kev optimization rau cov ntaub ntawv nyuaj yog qhov tseem ceeb. Koj xav tau cov cuab yeej txuas mus tas li, koj xav nce zeb qhov twg ua tau, koj xav tswj cov cua sov. Tus programmer uas tsuas yog siv cov tswv yim ua ntej yuav tau txais ib feem, tab sis lawv yuav hlawv los ntawm kev siv cuab yeej thiab kev pheej hmoo ua rau muaj kev ntxhov siab.
Kuv nco qab ua haujlwm nrog tus programmer ntawm titanium tivthaiv. Nws tau siv cov qauv zigzag pa. Lub cuab yeej lub neej yog txaus ntshai, thiab qhov kawg yog tsis zoo. Peb hloov mus rau txoj kev trochoidal milling rau roughing. Nws zoo li coj txawv txawv ntawm qhov simulation - cov voj voog, cheb cov lus tsa suab - tab sis nws khaws cov cuab yeej nyob rau hauv tas li, lub teeb txiav. Cov cuab yeej lub neej tripled, qhov ua tiav zoo dua qub, thiab peb txo lub sij hawm voj voog los ntawm 15%. Qhov ntawd yog qhov 'advanced' hauv CNC machining. Nws yog software txawj ntse siv rau lub cev txwv.
Lwm qhov hloov maj mam yog tom qab ua tiav. Lub tshuab maub los xav tau tus lej huv, muaj txiaj ntsig zoo. Lub clunky post processor uas tsis leverage qhov tshwj xeeb high-ceev machining zog ntawm koj Okuma los yog Makino yog tawm hauv kev ua tau zoo ntawm lub rooj. Tuning cov posts, feem ntau nyob rau hauv kev koom tes nrog lub tshuab cuab tam builder, yog ib tug tsaus nti kos duab uas them nyiaj faib loj nyob rau hauv lub smooth motion thiab txo lub sij hawm voj voog.
Kev sib xyaw ua ke: Thaum Casting ntsib Machining
Qhov no yog qhov uas tus qauv ntawm lub tuam txhab nyiam QSY ua kom muaj tswv yim ntau. Muaj plhaub pwm casting, peev casting, thiab CNC machining nyob rau hauv ib qho kev tswj cov qauv tshem tawm ib tug loj npaum li cas ntawm kev sib txhuam. Qhov mob taub hau loj tshaj plaws hauv kev tsim cov khoom lag luam yog qhov kev sib tw. Thaum tus neeg muag khoom casting thiab tus neeg muag khoom machining sib cais, koj tau txais qhov kev ua si liam. Qhov teeb meem machining? Lub tsev casting hais tias cov nyiaj pub dawb tau zoo. Ib qho teeb meem casting? Lub khw muag khoom hais tias cov khoom tsis raug.
Nrog ib tus neeg muab kev koom ua ke, kev lav phib xaub yog qhov tseeb. Qhov tseem ceeb tshaj, lub voj kev tawm tswv yim yog instantaneous. Pab pawg machining tuaj yeem qhia qhov chaw tsim khoom, Peb tab tom pom qhov porosity zoo ib yam ntawm lub ces kaum ntawm pwm, peb puas tuaj yeem hloov kho qhov rooj? Lub foundry tuaj yeem qhia tau tias, Cov hlau no yuav txo qis ntawm qhov tshwj xeeb no, yog li ntxiv ib qho ntxiv 0.5mm Tshuag muaj. Qhov kev sib koom tes, cov txheej txheem rov ua dua no yog li cas koj ua tiav kev ntseeg tau thiab tus nqi-zoo rau qhov nyuaj. Nws hloov cov saw hlau mus rau hauv kev sib tham, tsis yog kev sib pauv.
Piv txwv li, lub twj tso kua mis impeller hauv duplex stainless hlau yog tus neeg sib tw classic rau qhov no. Nws yog ib qho nyuaj, hydraulically rhiab zoo li zoo meej rau kev peev casting, tab sis nws yuav tsum tau muaj kev sib npaug ultra-precise thiab bore machining. Muaj ib pab neeg tswj xyuas tag nrho cov kev taug kev los ntawm cov hlau molten mus rau qhov sib npaug, cov khoom tiav tiav ua kom lub hom phiaj tsim tau khaws cia ntawm txhua kauj ruam. Cov machinists paub tias yog vim li cas ib qho kev siv lub kaum sab xis casting, thiab cov engineers foundry nkag siab txog cov ntaub ntawv tseem ceeb rau machining ops.
Tib neeg lub ntsiab hauv lub Ntiaj Teb Digital
Thaum kawg, rau tag nrho cov lus hais ntawm automation thiab advanced precision, nws tseem los rau tib neeg. Tus kws kho tsheb qub qub uas hnov qhov kev hloov ntawm lub suab ntawm kev txiav thiab nres lub tshuab ua ntej lub cuab yeej tawg. Tus kws tshuaj ntsuam xyuas zoo uas pom qhov pom qhov tsis pom kev ntawm CMM kev soj ntsuam tsis pom. Tus txheej txheem engineers uas pores tshaj SPC kab kos tab tom nrhiav rau ib tug qauv, tsis yog ib tug pass / poob.
Qhov kev txawj ntse no tau tsim ntau xyoo lawm, tsis tau rub tawm. Nws yog lub cuab tam tseem ceeb ntawm tej yam loj precision machining inc. Koj tsis tuaj yeem yuav nws nrog lub tshuab tshiab. Koj cog nws los ntawm cov haujlwm nyuaj, los ntawm kev ua tsis tiav (xws li kuv lub thermal expansion blunder), thiab los ntawm kab lis kev cai uas muaj nuj nqis rau cov khoom siv tes ua ntau npaum li cov thev naus laus zis. Thaum kuv saib tus neeg muag khoom lub peev xwm, kuv siv sijhawm ntau npaum li lub khw hauv pem teb tham nrog cov neeg ua haujlwm thaum kuv ua hauv chav sib tham saib lawv cov npe khoom siv peev.
