Lub npeHlau Pencil Koob​ muab tau los ntawm lawv kos npe "xum-point" terminus. Tsis zoo li cov lus qhia beveled lossis trocar, qhov geometry no muaj qhov elongated, ntse conical taw tes, feem ntau tsis muaj cov chaw nres nkoj sab lossis txiav ntug. Qhov kev tsim no ua rau muaj qhov tshwj xeeb ntawm cov ntaub so ntswg nkag thiab cov lus qhia meej. Raws li seasonedHlau Pencil Needles Chaw tsim tshuaj paus, peb tau txais kev txawj ntse hauv kev sib tsoo thiab burr -dawb tsim rau qhov tshwj xeeb lub tswv yim. Cov txheej txheem no hla tsuas yog shaping; nws xav tau kev txawj ntse ntawm cov khoom siv tshuab, sib tsoo cov thermodynamics, thiab micro-surface integrity.

Kev tsim cov cwj mem taub yog ntau-theem sib tsoo ua haujlwm. Ua ntej, kos cov hlau kawg hloov mus rau hauv lub khob hliav qab. Rau micro- koob (0.25-2 mm), qhov no yog qhov nyuaj heev. Peb siv tsib -axis CNC cuab yeej grinders nrog kev cai pob zeb diamond log. Kev sib tsoo nthuav tawm hauv peb theem: roughing, semi-ua tiav, thiab ua tiav. Roughing sai tshem tawm cov khoom lag luam ntau dhau, tsim kom muaj qhov yooj yim conical profile. Parameter tswj (lub log ceev, pub, qhov tob) yog qhov tseem ceeb. Cov chaw txhoj puab heev ua rau muaj cua sov ntau dhau, hloov cov stainless{13}}steel microstructure (xws li, temper softening lossis brittle martensite tsim), cuam tshuam cov tawv tawv thiab toughness. Peb ntiav "me me-thiab{18}}feem ntau" hla nrog siab-siab txias txias dej nyab kom qhov chaw sib tsoo qis dua 80℃.

Semi-kev ua tiav kho lub khob hliav qab thiab qhov ncaj. Wire Pencil Needles feem ntau muaj qhov ntev taper (linearly converging rau lub ntsis). Txoj kev sib tsoo lub log yuav tsum yog geometrically meej. Peb lub tshuab CNC ua cov txheej txheem sib xyaw ua ke, ua kom lub khob hliav qab du thiab seamless. Peb concurrently saib covtip lub vojvoog-zoo tshaj 5-20 µm. Cov lus qhia ntse heev (<5 µm) pierce easily but risk rolling or chipping; overly blunt tips (>20 µm) nce qhov kev quab yuam thiab cov neeg mob tsis xis nyob. Online laser ntsuas tshuab muab tiag tiag - lub sij hawm vojvoog tawm tswv yim, nws pib - kho qhov sib tsoo tsis.

Kev ua tiav thiab polishing tshem tawm cov micro- tsis xws luag. Kev sib tsoo ua ntej tawm cov kab mob microscopic thiab burrs-cov kev ntxhov siab thiab cov kab mob niches. Peb xa tawmelectrochemical polishing (ECM). Lub koob, raws li anode nyob rau hauv ib tug tshwj xeeb electrolyte, undergoes tswj anodic dissolution. Lub hauv paus ntsiab lus tseem ceeb,"micro-leveling,"​ governs this: high-current-density peaks dissolve faster than recessed valleys, smoothing the surface. ECM mus txog thaj chaw kho tshuab polishing tsis tuaj yeem, yam tsis muaj kev ntxhov siab tshiab. Ncej -ECM, tip deg roughness (Ra) poob qis dua 0.05 µm, ua tiav daim iav tiav. Qhov no drastic txiav insertion kev sib txhuam thiab boosts corrosion kuj thiab biocompatibility.

Burr{0}}dawb tsimyog peb lub hom phiaj. Mechanical sib tsoo inevitably tsim burrs. Txawm tias micron - qhov loj burrs tuaj yeem snag cov ntaub so ntswg, ua rau cellular puas lossis cov qauv paug. Peb lub tswv yim yog"kev tiv thaiv thawj zaug, tshem tawm thib ob."Optimized log grit, hardness, thiab hnav tsis kam minimize burr genesis. Tshaj tawm - sib tsoo, peb thovmicro-kev vibration deburring. Siab- zaus, qis- amplitude vibrating cov cuab yeej, coj los ntawm microscopy, maj mam cheb lub ntsis ntug, excising nascent micro- burrs yam tsis ua mob rau lub ntsis qauv.

Rau qhov loj - txoj kab uas hla (10–30 mm), sib tsoo sib npaug efficiency thiab lub zog. Siv nyob rau hauv orthopedics los yog kua dej, cov koob no tiv taus qhov tseem ceeb thrust. Peb txhob txwm ntxiv cov hlais hloov pauv ntawm lub hauv paus taub kom txo qis kev ntxhov siab. Hnav- cov kev kho mob tiv taus xws li nitriding lossis titanium txheej yuav ua raws. Tsis hais qhov loj me,concentricityyog sacrosanct. Lub taub hau lub apex yuav tsum ua tib zoo nrog cov xaim lub hauv paus axis. Eccentricity ua rau wobble thiab instability -ib qho tseem ceeb tsis xws luag peb categorically tsis lees paub.

Kev tswj kom zoo yog txhua yam. Peb lub-tier soj ntsuam system ua haujlwm: tus neeg teb xov tooj tus kheej- kuaj xyuas, hauv- txheej txheem kev soj ntsuam, thiab qhov kawg 100% kev tshuaj xyuas. High-Lub koob yees duab daws teeb meem nrog AI algorithms tshuaj xyuas txhua lub ntsiab lus taper, ncaj, vojvoog, thiab kev ncaj ncees ntawm qhov chaw. Tsis yog-cov khoom ua raws li nws pib- tsis lees paub. Periodic simulated puncture xeem siv cov ntaub so ntswg biomimetic validate penetration quab yuam thiab kev taw qhia raug. Tsuas yog cov qauv xeem dhau txhua qhov kev xeem tau txais kev tso cai tso tawm. Peb txoj kev xav nrog xaum- cov lus qhia zoo tshaj plaws tshwm sim los ntawm kev hwm rau kev nyab xeeb ntawm tus neeg mob thiab peb lub koob npe nrov ua cov chaw tsim khoom tseem ceeb.
