1. Qhov cuam tshuam ntawm kev sib tsoo tshuab kev teeb tsa thiab kev hloov kho ntawm Hniav Sharpening:
(1) Thaum txhim kho lub tshuab sib tsoo, xyuas kom ruaj ntseg kom tsis txhob muaj kev vibration; tag nrho cov fasteners yuav tsum tau ruaj ntseg txuas, thiab lub sib tsoo log yuav tsum tig smoothly tsis wobbling los yog dhia. Tsis ua li ntawd yuav ua rau cov hniav tsis tuaj yeem ua kom zoo, uas ua rau muaj qhov tsis xws luag xws li serrated txiav npoo.
(2) Lub log sib tsoo yuav tsum yog perpendicular rau lub dav hlau kab rov tav; txwv tsis pub, cov hniav tsis tuaj yeem sharpened kom zoo.
(3) Cov khoom sib tsoo yuav tsum tau muab tso rau ntawm 6 hli ntawm lub log thiab nyob ntawm qhov nruab nrab ntawm lub log lub vojvoog. Qhov chaw tsis raug ntawm lub fixture tuaj yeem yooj yim ua rau tsis sib xws ntawm cov hniav. Qhov ntev ntawm tus pas nrig ncua kev kawm kuj plays lub luag haujlwm; yog tias tsis raug, nws ua kom luv ntawm kev sib tsoo, tiv thaiv cov hniav kom zoo.
(4) Rau cov tshuab sib tsoo uas tau tsav los ntawm kev sib tsoo, V- txoj siv tawv yuav tsum tau teem rau theem tsim nyog kom ntseeg tau tias lub log sib tsoo ncav cuag nws qhov ntsuas kev sib hloov ceev. Kev sib tsoo lub log ceev uas tsawg dhau yuav cuam tshuam qhov kev ua tau zoo ntawm cov txheej txheem sharpening.
2. Qhov cuam tshuam ntawm Abrasive Composition ntawm Hniav Sharpening:
(1) Ntau dhau abrasive (xws li, emery) nyob rau hauv kev sib tsoo sib xyaw: Cov hniav txiav ntug yuav khawb li txheej tuab ntawm abrasive; qhov no ua rau cov ntug hnav sai heev, ua rau nws nyuaj rau ua tiav qhov ntse.
(2) Tsis txaus abrasive nyob rau hauv sib tsoo compound: Cov hniav yuav nyuaj rau sharpen mus rau ib tug ntse ntug, thiab lub sij hawm sib tsoo ntev yuav ua rau muaj kev pheej hmoo ntawm annealing (softening) thiab deformation.
3. Qhov cuam tshuam ntawm kev khiav hauj lwm cov txheej txheem ntawm Hniav Sharpening:
(1) Lub siab tsis sib xws: Qhov no ua rau tsis sib xws ntawm cov hniav, ua rau tsis sib haum xeeb ntawm cov hniav ntawm tus kheej. Tsis tas li ntawd, siv lub siab tsis sib xws thaum oscillating cov hniav tuaj yeem ua rau qhov chaw ntawm cov hniav tuaj yeem tawm sab nraud.
(2) Kev siab dhau: Qhov no yooj yim ua rau annealing thiab deformation ntawm cov hniav, yog li ua rau nws lub neej ua haujlwm luv.
(3) Lub siab tsis txaus: Cov hniav tsis tuaj yeem tuav ruaj khov nrog kev sib tsoo lub log, ua rau muaj qhov tsis sib xws, kev puas tsuaj rau cov hniav, thiab bulging hauv nruab nrab ntawm cov hniav.
(4) Ntau zaus oscillation ceev: Qhov no feem ntau cuam tshuam cov kev sib tsoo thiab yuav ua rau cov hniav tawg. Nws kuj ua rau nws nyuaj rau kev tswj cov hniav sib npaug, ua rau lub siab tsis sib xws, hnav tsis sib xws, thiab bulging hauv nruab nrab.
(5) Tsis txaus oscillation ceev: Qhov no accelerates hnav ntawm cov hniav, shortens nws cov kev pab cuam lub neej, thiab tsub kom qhov kev pheej hmoo ntawm cov hniav undergoing annealing.
(6) Luv sharpening stroke: Qhov no tsis tsuas yog ua tsis tau zoo sharpening hniav, tab sis kuj ua rau qhov chaw ntawm lub sib tsoo log nto los ua concave sai, yog li shortening cov kev pab cuam lub neej ntawm lub sib tsoo log. Yog li ntawd, lub sharpening stroke yuav tsum tau khaws cia ntev li ntev tau.
(7) Lub sij hawm sharpening ntau dhau ntawm lub log sib tsoo nrog cov ntaub abrasive: Qhov no ua rau cov hniav tuaj yeem ua rau annealing thiab deformation.
