Nyob rau hauv lub realm ntawm precision kho mob khoom manufacturing, zus tau tej cov Hlau Pencil Koob​ originates nyob rau hauv lub microcosm ntawm raw khoom metallurgy. Raws li tus kws tshaj lijHlau Pencil Needles Chaw tsim tshuaj paus, peb nkag siab tias qhov kev ua tau zoo qab nthab ntawm qhov zoo li yooj yim, elongated ntsuas yog tsim los ntawm qhov zoo ntawm stainless- steel hlau pas nrig. Spanning diameters los ntawm 0.25 mm mus rau 30 mm nthuav qhia nyob ze -cov kev xav tau ntawm cov khoom siv purity, homogeneity, thiab kev tswj cov txheej txheem kos duab. Kab lus no tshawb txog peb lub tswv yim tseem ceeb ntawm kev tsim khoom, los ntawm kev tshuaj xyuas cov khoom siv raw mus rau tag nrho -spectrum precision hlau kos duab.

Lub sij hawmHlau Pencil Koob​ muab los ntawm rab koob lub cev qhov profile -ntev, ncaj, thiab tapered zoo li ib tug cwj mem-tsis tau nws cov tub ntxhais tseem nyob stainless- steel hlau pas nrig. Peb feem ntau xaiv ASTM- qauv 304, 304L, 316, thiab 316L kho mob- qib stainless hlau. Cov kev xaiv no yog txhob txwm tshaj tawm, tau tsav los ntawm lawv cov kev tiv thaiv corrosion zoo tshaj thiab biocompatibility. Txawm li cas los xij, kub- dov hlau rods los ntawm steel mills tsis tsim nyog rau kev tsim khoom ncaj qha. Encased nyob rau hauv oxide nplai, lub nra hnyav los ntawm kev ntxhov siab, thiab tsis muaj kev pom zoo microstructure, cov pas nrig thawj zaugpeeling thiab sib tsoo. Siv cov cuab yeej siv tshuab ua kom zoo, peb tshem tawm 0.1 hli mus rau 0.3 hli ntawm tus pas nrig nto, tshem tawm kom huv si sub- cov pob khaus, tawg, thiab nplai. Cov kauj ruam no yog qhov tseem ceeb rau micro- txoj kab uas hla (piv txwv li, 0.25 mm); txhua qhov chaw microscopic flaw amplifies thaum lub sij hawm tom qab deformation, pheej hmoo rau qhov kawg koob puas.

Cov txheej txheem tseem ceeb yogmulti- dhau daim duab txias. Cov txheej txheem no incrementally txo tus pas nrig txoj kab uas hla mus rau lub hom phiaj dimension. Rau micro- txoj kab uas hla (0.25–2 mm), qhov no suav nrog 15 mus rau 25 daim duab sib law liag. Nyob rau hauv txhua kis, cov hlau yog rub los ntawm lub pob zeb diamond tuag nrog ib tug me ntsis aperture. Yas deformation tshwm sim, txo tus ntoo khaub lig-section, nce ntev, thiab nce tensile zog. Tswj lubhla txo tus nqiyog peb cov kws tshaj lij kev tshaj lij. Kev txo qis ntau dhau ua rau kev ua haujlwm nrawm nrawm thiab tawg; Kev txo qis tsis txaus txo qis kev ua haujlwm thiab tsis ua tiav cov khoom siv kho tshuab uas xav tau. Peb ntiav cov khoos phis tawj- tswj cov duab kos nrog nano- qib pob zeb diamond tuag, kom ntseeg tau tias deformation nyob rau hauv cov khoom txwv. Cov xab npum tshwj xeeb emulsions lossis polymer lubricants txo kev sib txhuam thiab tiv thaiv cov hlau los ntawm kev tawg thaum lub sij hawm siab - nrawm nrawm.

Rauloj - koob (10–30 mm), peb txais aua ke txias dov thiab kos duab txheej txheem. Ib qho kev kos duab ua pov thawj tsis muaj txiaj ntsig ntawm cov kab loj loj thiab kev tawm tsam kom ntseeg tau tias muaj kev sib tw. Peb thawj zaug txo tus pas nrig ntawm peb - yob txias reducer kom ze rau - qhov kawg loj, ua raws li los ntawm ib mus rau peb qhov kev ua tiav. Txoj kev no boosts efficiency thiab refines lub grain qauv, txhawb zog thiab toughness. Txawm hais tias txoj kab uas hla, tuag concentricity yog nruj me ntsis tswj. Rau 0.25 hli xov hlau, phab ntsa thickness kam rau ua yuav tsum nyob rau hauv ± 0.002 hli, thov micron - theem tuag precision. Ib qho ellipticity lossis eccentricity ua rau muaj kev ntxhov siab tsis sib xws thaum puncture, pheej hmoo khoov lossis tawg.

Kev kho cua sovyog tus ntsuj plig ntawm kev kos duab. Kev kos duab txias ua rau muaj kev ntxhov siab loj heev, thiab kev ua haujlwm hnyav ua rau cov khoom tawg. Txhawm rau rov qab plasticity, peb uanruab nrab annealing. Peb qhov hluav taws xob txuas ntxiv ci ntsa iab ua haujlwm nyob rau hauv kev tiv thaiv huab cua (hydrogen lossis dissociated ammonia), cua sov cov hlau kom txog li 1050 degree, tuav, ces maj mam txias. Qhov no tshem tawm kev ntxhov siab thiab recrystallizes cov hlau. Rau cov koob tiav lawm, peb siv cov tshuaj kho zaum kawg lossis kev ntxhov siab los tiv thaiv kev ua haujlwm deformation. Peb cov kws ua haujlwm thermal calibrate qhov cub kub, kab nrawm, thiab cov cua txias kom ntseeg tau tias txhua pawg ua tau raws li cov qauv kev kho mob microstructure.

Nto zoo tsis yog -negotiable. Kev kos duab inevitably tso cov roj nplaum seem, hmoov av hlau, lossis micro- khawb. Cov flaws no degrade qaug zog tiv thaiv thiab tiv thaiv corrosion. Yog li ntawd, peb muab kev sib koom ua ke hauv online eddy-tam sim no testers thiab laser gauges, tshuaj xyuas txhua lub 'meter' rau txoj kab uas hla sib xws thiab qhov tsis xws luag. Ib qho anomaly ua rau kev tsis lees paub tam sim. Ultrasonic tu thiab electropolishing ua ntej-kev kho mob ntxiv kom cov hlau nto yog daim iav- du thiab tsis muaj paug{10}}dawb ua ntej cov txheej txheem qis.

Traceability yog qhov tseem ceeb. Txhua lub stainless-steel coil muaj tus naj npawb ntawm cov cua sov tshwj xeeb, sau nws cov keeb kwm yaj, chemistry, thiab cov khoom siv tshuab. Thaum lub sij hawm kos duab, peb tswj hwm "ib pawg, ib daim npav" system, kos duab kos duab, tus ID tuag, thiab cov ntsiab lus ntawm tus neeg teb xov tooj. Qhov kawg no -rau-kawg traceability-los ntawm cov hlau molten mus rau rab koob- ua kom cov hauv paus sai sai- ua rau kev soj ntsuam ntawm ib qho teeb meem zoo. Peb lub hom phiaj tsis tu ncua ntawm cov ntaub ntawv raw thiab kos duab craftsmanship ua lub hauv paus ntawm Hlau Pencil Needles 'zoo, ua kom ntseeg tau kev ua tau zoo nyob rau hauv qhov chaw kho mob xav tau tshaj plaws.
