Thaum cov kws tshaj lij qhia cov khoom siv yas rau lub tshuab hluav taws xob aerospace, cov tsev kho mob cog, lossis cov cuab yeej siv hluav taws xob semiconductor wafer, "precision plastic machining factory" tsis yog ib lo lus tshawb nrhiav - nws yog qhov yuav tsum tau sib tham tsis tau. Tolerances nruj dua ± 0.005 hli, nto tiav nyob rau hauv Ra 0.4 µm, thiab xoom warpage tom qab sterilization los yog thermal cycling xav tau ntau tshaj tus qauv CNC khw yuav xa. Peb tau pom cov neeg siv khoom rov qab los ntawm peb tus neeg muag khoom nrog cov khoom uas dhau los ntawm qhov ntsuas qhov ntsuas-tab sis ua tsis tiav qhov kev ntsuas lub tshuab nqus tsev vim yog micro-tawg los ntawm qhov seem seem. Tias yog vim li cas tus sib txawv tiag tiag tsis yog cov cuab yeej siv xwb - nws yog li cas cov khoom siv coj los siv, lub tswv yim zoo, thiab kev tswj ib puag ncig cuam tshuam hauv ib qho kev ua haujlwm sib koom ua ke.
Vim li cas cov yas tsis yog "hlau yooj yim dua"-Thiab yog vim li cas qhov kev xav yuam kev raug nqi sijhawm thiab nyiaj txiag
Ntau pawg neeg yuav khoom xav tias kev siv lub tshuab yas yog qhov yooj yim dua li cov hlau: qis txiav quab yuam, tsis muaj qhov xav tau coolant, lub sij hawm voj voog sai. Tab sis precision yas machining Hoobkas ua hauj lwm ntsib cov cim physics-raws li txwv. Acrylic creep nyob rau hauv clamping siab. PEEK absorbs ya raws - o mus txog 0.3% ua ntej machining, ces shrinking unpredictably thaum ziab. Polycarbonate softens ntawm 140 ° C; ib qho dhau los nrog cov nti tsis txaus tuaj yeem tsim kom muaj cua sov hauv zos txaus kom yaj qhov chaw txiav. Peb ib zaug taug qab ib pawg ntawm qhov ua tsis tau zoo kho qhov muag lens nce mus rau ambient humidity spikes thaum lub sij hawm ua ntej machining cia - tsis yog CNC program. Tias yog vim li cas cov chaw saum toj kawg nkaus kho cov yas zoo li cov khoom siv tsis zoo: huab cua tswj cov khoom siv raw khoom, kev ntsuas kub hauv cov txheej txheem, thiab cov cuab yeej ua kom zoo rau cov cua sov dissipation - tsis yog ceev xwb.
Plaub lub peev xwm tsis sib tham koj yuav tsum txheeb xyuas (ua ntej xa koj thawj daim duab)
Tsis txhob cia siab rau daim ntawv teev npe "CNC milling" thiab "ISO 9001." Nug plaub nqe lus nug no-thiab xav tau pov thawj:
- Puas yog lawv tau lees paub cov ntaub ntawv ntau ntxiv mus rau ASTM D638 tensile cov ntaub ntawv? Tsis yog tus neeg muab ntawv pov thawj nkaus xwb-cov ntaub ntawv xeem tiag tiag los ntawm lawv tus kheej lub chaw kuaj mob lossis cov neeg thib peb tau lees paub. Peb pom ib tus neeg muag khoom siv "qib kho mob PTFE" uas tau ntsib FDA 21 CFR tab sis ua tsis tiav ASTM F758 biocompatibility specs vim tias cov ntsiab lus muab tub lim sib txawv ntawm cov khoom siv.
- Lawv puas tuaj yeem ua pov thawj thermal stabilization raws tu qauv? Cov khoom siv los ntawm extruded pas nrig yuav tsum tau tswj xyuas kev sib tsoo * ua ntej * qhov kawg ua tiav - txwv tsis pub muaj kev ntxhov siab sab hauv tso tawm tom qab xa khoom. Nug lawv lub sijhawm so / qhov kub thiab txias rau Delrin® thiab Ultem®.
- Lawv puas siv pob zeb diamond-coated los yog cov khoom siv-carbide nkaus xwb rau qhov chaw kho qhov muag? Txheem HSS cov cuab yeej tawm micro-kua kua cim ntawm PMMA uas tawg lub teeb. Peb ntsuas qhov kev ncaj ncees ntawm qhov chaw nrog dawb-lub teeb interferometry-tsis yog stylus profileometers xwb.
- Puas yog GD&T txhais lus ua rau hauv kev tshuaj xyuas engineering-tsis yog outsourced? Qhov "txoj hauj lwm tseeb" hu rau ntawm lub tsev yas tsis yog hais txog qhov chaw nyob ib leeg. Nws yog hais txog yuav ua li cas shrinkage gradients cuam tshuam nrog pwm kab offsets. Yog tias lawv pab neeg tsis tuaj yeem taug kev koj los ntawm qhov xwm txheej phem tshaj plaws uas siv koj cov ntaub ntawv CTE tiag tiag, taug kev mus.
Kev sib xyaw ntsug ntsug feem ntau cov neeg yuav khoom saib dhau
Nov yog qhov tsis tshua muaj tshwm sim hauv cov vev xaib: feem ntau "cov chaw tsim khoom yas machining" outsource cov kauj ruam tseem ceeb. Lawv tshuab-tab sis xa cov khoom mus rau lwm lub khw rau vapor polishing, electrostatic paug (ESD) txheej, lossis kev sib sau ua ke. Txhua qhov kev tuav pov hwm ntxiv kev pheej hmoo: kev kis kab mob, qhov dav dav, ploj traceability. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb khiav yas machining ib sab ntawm peb cov hlau thiab cov kab nrib pleb-tsis yog cov chaw sib cais, tab sis raws li cov txheej txheem sib cuam tshuam. Vim li cas qhov ntawd tseem ceeb? Vim tias thaum tus neeg siv khoom xav tau cov khoom sib xyaw - lub cev tsis muaj steel hlau nrog lub tes tsho PEEK sib xyaw - peb tshuab ob qho tib si ntawm tib lub CMM-calibrated platform, siv cov qauv sib koom ua ke thermal. Tsis muaj kev kwv yees txog qhov sib txawv ntawm qhov sib txawv thaum lub sij hawm sim ua haujlwm. Qhov kev sib koom ua ke no txiav lub sijhawm ua haujlwm los ntawm 37% ntawm ntau cov khoom sib dhos - thiab tshem tawm 92% ntawm kev cuam tshuam cuam tshuam nrog kev ua tsis tiav hauv hydraulic system prototypes.
Dab tsi "High-Tolerance" tiag tiag txhais tau tias hauv kev coj ua (thiab Yuav Ua Li Cas Qhia Nws Zoo)
"High-tolerance" tsis muaj ntsiab lus tsis muaj ntsiab lus. A ± 0.01 hli kam rau ntawm 50 hli acrylic bracket yog niaj hnub. Tib qhov kev zam rau ntawm 300 hli polycarbonate optical lub rooj ntev zaum? Qhov ntawd yuav tsum muaj lub tshuab nqus tsev-chuck fixturing, sub-1 µm spindle runout, thiab lub sijhawm tiag tiag kev co damping-vim txawm tias hauv pem teb-borne resonance los ntawm ze forklifts hloov yas ntau dua hlau. Peb qhia cov neeg siv khoom kom paub meej txog kev ua siab ntev los ntawm * kev ua haujlwm *, tsis yog qhov loj me xwb: "Yuav tsum tuav 0.002 hli parallelism ntawm mating nto hauv qab 200 kPa hydraulic load" ntaus "± 0.005 hli flatness." Qhov ntawd qhia peb qhov twg los faib cov peev txheej metrology - thiab seb puas yuav pom zoo kom txo qis kev ntxhov siab lossis hloov mus rau PEEK uas muaj iav kom nruj. Tsis tas li: ib txwm hais txog qhov ntsuas ntsuas. "As-machined" txhais tsis muaj dab tsi. "Kev ntsuas ntawm 23 ° C ± 1 ° C, 50% RH, 4 teev tom qab tshem tawm ntawm huab cua-tswj ntim ntim" - uas yog qhov ua tau.
Xaiv lub tshuab yas machining precision tsis yog hais txog kev sib piv cov lus. Nws yog hais txog kev txheeb xyuas leej twg yog tus tswv lub physics - los ntawm polymer crystallinity mus rau cov cuab yeej deflection mus rau ib puag ncig hysteresis. Tus khub zoo tsis yog tuav lub siab ntev; lawv cia siab tias koj txoj haujlwm yuav coj li cas hauv nws qhov chaw kawg. Tias yog vim li cas engineers ntawm Tier-1 cov tuam txhab kho mob thiab semiconductor OEMs tsis tu ncua rov qab mus rau cov chaw uas cov yas tsis yog qhov kev xav tom qab - nws tau tsim kho nrog tib yam nruj raws li superalloy turbine hniav. Precision pib ntev ua ntej thawj nti ya.
