Yuav ua li cas tuav riam yog ib qho kev txhawj xeeb rau cov neeg nyiam sab nraum zoov thiab cov riam. Tom qab tag nrho, ib rab riam zoo tsim nyog peb saib xyuas zoo. Txhawm rau kom cov riam ua lub luag haujlwm ntau dua thiab muaj lub neej ntev, yuav tsum tau saib xyuas ntau zaus.
Yog li yuav ua li cas tswj lub cuab yeej? Siv cov hlau polished kom ntse riam thiab ua kom cov hniav ntse yog ib txoj hauv kev zoo los tswj cov riam, tshwj xeeb tshaj yog rau cov riam hauv chav ua noj thiab lwm cov riam uas nquag siv.
Cov phooj ywg uas muaj kev paub txog riam tau hais tias yog cov riam siv ntau zaus, lawv yuav tsum tau muab cov riam ntau zaus, tsawg kawg ib zaug ua ntej thiab tom qab siv txhua. Qhov tseeb, kev sib tsoo hlau tsis yog tiag tiag sharpening cov hniav, tab sis kho thiab tu ntug ntawm riam.
Ib qho yooj yim polished steel yog ib tug hlau pas nrig nrog ib tug kov, nrog ncaj nqaim grooves faib rau nws. Cov hlau polished zoo dua yog magnetized, uas tuaj yeem nyiam cov molecules ntawm lub cuab yeej los kho lawv hauv txoj kab ncaj nraim.

Yuav ua li cas tuav riam, polishing yog ib qho tseem ceeb.
Siv tej yam ntuj tso grindstone kom ntse riam
Ua ntej, peb sau cov hom ntawm cov pob zeb ntuj uas tuaj yeem siv rau polishing thiab lawv qhov sib npaug ntawm qhov sib npaug (kev sib tsoo muaj peev xwm):
Vashta Pob zeb-zoo li marble, nrog ib qho me me sib npaug ntawm 300-350. Ib qho zoo pib sanding pob zeb, uas tuaj yeem tshem tawm cov khawb me me thiab tsim ib qho beveled contour.
Hard Arkansas-dawb los yog lub teeb grey, nrog ib tug particle loj sib npaug ntawm 500-600. Siv los ua kom tiav cov npoo ntawm qhov kawg ntawm cov xuab zeb.
Dub tawv Arkansas-dub lossis grey tsaus, nws qhov loj me feem ntau yog 800-1000. Cov pob zeb polishing zoo heev, tuaj yeem siv los txhuam cov hniav kom ntse li rab chais. Tau ntau xyoo, cov pob zeb zoo li no tau yuav luag tag, thiab tsuas yog ob peb qhov chaw tseem tsim cov pob zeb no. Feem ntau, hom pob zeb no tsis xav tau rau cov riam ntse. Thaum xub thawj, tsuas yog cov neeg siv folding rab chais nyiam siv nws los ua kom cov riam. Feem ntau hais lus, peb xaiv ib daim ntawm pob zeb wastar thiab ib daim ntawm Arkansas nyuaj raws li ntuj grindstones. Qhov loj ntawm cov pob zeb yog nyob ntawm qhov ntev ntawm cov hniav.
Piv txwv li: portable riam-3-5" ntev grindstone, yos hav zoov riam-4-8" ntev grindstone, chav ua noj riam-6-8" ntev grindstone
Thaum sharpening riam, xyuam xim rau cov kev txawj ntse thiab siv sharpening roj los tiv thaiv me me hlau chips los ntawm embedded nyob rau hauv lub grindstone. Tsis txhob siv cov roj lubricating zoo tib yam, uas yuav thaiv qhov chaw ntawm cov pob zeb. Lub kaum sab xis ntawm kev sib cuag ntawm cov hniav thiab cov pob zeb thaum lub sij hawm sharpening yog qhov nyuaj tshaj plaws los tuav. Muab cov riam ncaj nraim rau ntawm lub pob zeb, thiab maj mam tsa lub nraub qaum ntawm rab riam kom txog thaum txoj kab nqes ntawm cov hniav yog sib npaug mus rau saum npoo ntawm whetstone. Yog tias koj tsa nws siab dhau, nws yuav plam tus hniav, thiab yog tias nws qis dhau, cov hniav yuav tsis ntse. Koj tuaj yeem sim Polished ntawm lub kaum sab xis ntawm 20 degrees. Thaum sib tsoo, cov roj ntau ntau yuav tsum tau them rau ntawm cov pob zeb, thiab kev sib tsoo qhuav tsis raug tso cai, vim tias cov chips hlau yuav raug muab tshem tawm thiab muab tso rau hauv qhov chaw ntawm cov pob zeb, ua rau cov pob zeb thiab cov hniav ntuag.
Pib ntxhib sanding nrog Vashta grindstone. Taw tes rau ntawm lub ntsej muag ntawm lub pob zeb thiab lub nraub qaum ntawm rab riam rau koj tus kheej, thiab ua kom lub ntsej muag lub ntsej muag ntawm 20-degree lub kaum sab xis nrog lub pob zeb nto, thiab tom qab ntawd thawb lub riam rau pem hauv ntej zoo li koj tab tom sim zom pob zeb. Lub hauv ntej kawg yog txiav zoo li ib daim me me. Rov ua qhov kev txav no los ntawm hauv qab mus rau sab saum toj 2-3 zaug, tom qab ntawd rov qab rab riam kom lub ntsej muag ntsej muag rau koj, thiab tom qab ntawd siv lub ntsej muag riam los ua 20-degree lub kaum sab xis nrog cov nplais pob zeb, thiab txhuam tib lub sijhawm. Nco ntsoov tias tus naj npawb ntawm polishing ntawm ob sab yuav tsum yog tib yam. Thaum cov txheej txheem polishing no tiav, ib txoj kab bevel ntshiab tuaj yeem tau txais, yog li koj tau npaj nkag mus rau qhov kawg polishing txheej txheem. Peb siv ib qho nyuaj Arkansas grindstone rau nplua sanding. Ib yam li ntawd, koj yuav tsum tau siv ntau cov roj sharpening rau saum npoo ntawm cov pob zeb thiab rov ua cov xuab zeb ntxhib kom txog thaum koj tau txais qhov ntse koj xav tau, thiab cov xuab zeb tiav.
Thov nco ntsoov tias cov pob zeb yuav tsum tau muab ntxuav nrog ib daim ntaub tom qab txhua polishing, thiab txhua txhua xyoo, koj yuav tsum ntxuav cov pob zeb kom huv si nrog cov tshuaj tshwj xeeb thiab txhuam txhuam kom cov kab noj hniav ntawm cov pob zeb tsis thaiv thiab ntxuav. Nco ntsoov: riam phom yog qhov txaus ntshai dua! Qhov tseeb, rab riam ntse ntse muaj kev nyab xeeb dua li riam riam, vim nws txiav tau yooj yim, tsis xav kom koj siv zog los yog saib tsis zoo ntawm kev ua haujlwm, thiab ua haujlwm zoo dua. Txawm hais tias riam phom kim npaum li cas thiab zoo heev, nws tsis tuaj yeem tswj hwm nws qhov ntse ntawm nws tus kheej, yog li koj yuav tsum ua ntu zus thiab tswj cov riam ntug kom nws nyob hauv qhov zoo tshaj plaws.
Yog tias koj siv lub tshuab ntse, ua ntej siv dej me ntsis rau ntawm lub pob zeb diamond saum npoo ntawm lub tshuab ntse, tig rov qab ntawm rab riam rau koj, thiab cov hniav kov lub ntsej muag ntawm lub kaum sab xis ntawm 20 °. Thawb rab riam los ntawm ib qho kawg ntawm rab riam mus rau lwm qhov, piv txwv li, rub lub sab saum toj los ntawm sab hauv qab ntawm rab riam, tom qab ntawd rov qab riam, thiab thawb rau lwm sab ntawm cov hniav los ntawm sab saum toj ntawm rab riam rov qab mus rau qhov chaw. hauv qab.
