I. Kev Npaj Ua Ntej Nthuav
Ua ntej pib sharpening, kev ceev faj txog kev nyab xeeb thiab kev kuaj mob yuav tsum tau ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo.
Hnav Cov Khoom Siv Tiv Thaiv Tus Kheej: Ib txwm hnav cov txiav- cov hnab looj tes tiv thaiv, tsom iav, thiab daim npog ntsej muag kom tiv thaiv cov hlau shavings lossis txiav los ntawm cov hniav.
Tshawb xyuas lub Squeegee Lub Cev: Paub meej tias lub squeegee yog dawb los ntawm kev khoov hnyav, tawg, lossis hauv zos hnav. Yog tias pom muaj deformation loj lossis tawg, hloov tam sim ntawd; tsis txhob sim ua kom ntse.
Ntxuav lub Squeegee Surface: Siv txhuam txhuam los yog daim txhuam cev kom tshem tawm cov kua nplaum uas seem thiab cov impurities, tsis txhob siv cov khoom tawv tawv uas tuaj yeem khawb cov hniav thaum lub sij hawm sharpening.
Npaj Cov Cuab Yeej Siv Tau: Cov cuab yeej muaj xws li cov ntaub ntawv tiaj tus nruab nrab, cov pob zeb ntxhib thiab cov roj zoo (220 # ~ 600 # pom zoo), thiab lub tshuab ntse ntse nrog lub tshuab ua kom txias. Kev tuav ntse ntse yog tsim rau cov xwm txheej kub ntxhov, thaum lub tshuab ntse ntse yog qhov zoo dua rau kev ua batch thiab siab - qhov yuav tsum tau ua.
II. Standard Sharpening txheej txheem
1. Cov ntaub ntawv pib los ua Daim Ntawv Txiav Ntug: Siv cov ntaub ntawv tiaj tus los ua cov ntawv scraper ntawm lub kaum sab xis 15-20 degree. Qhov no yog lub kaum sab xis yooj yim kom ntseeg tau tias txawm khawb. Kev ua ntaub ntawv yuav tsum tau ua kom zoo nyob rau hauv ib qho kev taw qhia, tsis txhob rov qab - thiab - ua ntaub ntawv uas tuaj yeem ua rau burrs. Siv txawm tias lub siab los tiv thaiv dhau - sib tsoo hauv qee qhov chaw, uas tuaj yeem ua rau lub ntsej muag zoo nkauj ntawm ntug txiav. Ib daim ntaub tuab tuab tuaj yeem muab tso rau hauv ib sab ntawm cov ntaub ntawv los tiv thaiv tes slippage thiab raug mob.
2. Ua kom tiav cov ntse kawg: Cov ntse kawg ntawm cov scraper uas tiv tauj lub voj voog yuav tsum tau muab sib npaug thiab smoothed nrog cov ntaub ntawv zoo. Qhov no yog ib qho kev ntsuas tseem ceeb los tiv thaiv khawb cov phab ntsa sab hauv ntawm lub voj voog ncig thaum ua haujlwm; txwv tsis pub, nws tuaj yeem yooj yim ua rau wrinkles lossis tsis xws luag xws li pinholes.
3. Oilstone Polishing los txhim kho Smoothness: Ua ntej, siv cov coarse oilstone dipped nyob rau hauv tshuab roj polish thiab tshem tawm cov ntaub ntawv cim kom txog thaum lub txiav ntug yog ncaj thiab tsis muaj wavy kab. Tom qab ntawd, siv lub pob zeb zoo rau polishing kom ua tiav daim iav -zoo li smoothness. Thaum lub sij hawm sib tsoo, siv tus pas ntsuas lub sij hawm los xyuas kom meej tias qhov kev ua yuam kev ncaj tsis tshaj 0.1 hli raws qhov ntev.
4. Tshem tawm Burrs thiab me ntsis Chamfering
Tom qab sib tsoo, maj mam txhuam sab nraub qaum ntawm cov hniav nrog cov ntawv xuab zeb zoo los yog cov tawv tawv kom tshem tawm cov burrs me me. Me ntsis chamfering (kwv yees li 0.02-0.05mm) tuaj yeem siv los txhim kho cov hniav cuam tshuam thiab tiv thaiv chipping thaum siv.
III. Kev tshuaj xyuas thiab khaws cia tom qab sib tsoo
Tom qab sib tsoo, yuav tsum tau kuaj pom thiab ua haujlwm:
Saib xyuas cov hniav ntug kom ncaj, smoothness, thiab tsis muaj cov kab wavy pom tseeb lossis dents.
Tactile Test: Lub ntug yuav tsum zoo nkaus li du thiab tsis yog -prickly rau kov, tsis tau muaj ib tug tej℃ntawm sharpness.
Kev Xeem Ua Tau: Maj mam khawb daim ntawv nrog av scraper. Yog hais tias nws txiav smoothly tsis tearing, lub sharpness ua tau raws li tus qauv.
Tom qab sib tsoo, tam sim ntawd siv ib txheej ntawm xeb- tiv thaiv cov roj rau ntawm cov hniav thiab khaws cov scraper vertically nyob rau hauv ib tug tshwj xeeb riam tuav kom tsis txhob muaj kev sib tsoo los yog oxidation los ntawm noo noo.
IV. Kev ceev faj thiab cov txheej txheem sib txuam cov lus pom zoo
Tswj cov khoom tshem tawm thaum lub sij hawm sib tsoo: Cov khoom tshem tawm thaum txhua qhov sib tsoo yuav tsum tsis pub tshaj 0.1 hli. Kev sib tsoo ntau dhau yuav ua rau cov hniav luv luv.
Tsis txhob sib tsoo qhuav: Txawm hais tias kev sib tsoo manually lossis mechanically, lubricating roj los yog coolant yuav tsum tau txuas ntxiv kom tsis txhob muaj hlau annealing thiab txo hardness vim qhov kub thiab txias.
Kho kev sib tsoo lub tswv yim raws li tus qauv: Thaum luam ntawv zoo kab qauv, ib tug sharper hniav ntug thiab ib tug me me lub kaum sab xis yuav tsum tau txhim kho qhov tseeb ntawm squeegee tswj; rau cov luam ntawv tuab tuab lossis loj- cheeb tsam tag nrho- dhau cov qauv, me ntsis blunt hniav ntug tuaj yeem khaws tau los txhim kho kev hnav tsis kam thiab txo qis kev hloov pauv ntau zaus.
Tsim kom muaj kev tiv thaiv kev sib tsoo: Nws raug nquahu kom ua kev sib tsoo txhua 2-3 qhov kev txiav txim loj lossis tom qab kev ua haujlwm ntau dua 300 teev, tsim kom muaj kev tu tus cwj pwm.
