Cov tshuaj tiv thaiv hauv kev sib tsoo

Sib tsoo lub workpiece yog ib qho kev lag luam hauv kev lag luam ntau lawm, thiab ntau tus neeg yuav xav tias nws tsuas yog cov txheej txheem ntawm lub cev yooj yim, uas yog, kev sib tsoo ntawm qhov chaw ua haujlwm los ntawm kev sib tsoo lub log. Txawm li cas los xij, raws li tus kws qhia chemistry, kuv xav qhia koj tias hauv cov txheej txheem no, kev hloov tshuaj lom neeg tsis tuaj yeem tsis quav ntsej. Kev nkag siab txog cov tshuaj hloov pauv no pab peb tswj cov txheej txheem sib tsoo zoo dua thiab txhim kho qhov zoo ntawm cov khoom ua haujlwm.

Ua ntej ntawm tag nrho cov, peb yuav tsum to taub lub ntsiab Cheebtsam ntawm lub sib tsoo log. Sib tsoo log feem ntau muaj cov abrasives, bonds thiab pores. Abrasive yog ib feem tseem ceeb ntawm kev sib tsoo log, feem ntau corundum (tsuas yog alumina), silicon carbide thiab lwm yam. Thaum lub sij hawm sib tsoo, cov abrasive tuaj rau hauv kev sib cuag nrog lub ntsej muag ntawm lub workpiece, tshem tawm cov khoom los ntawm qhov chaw ntawm lub workpiece los ntawm kev ua txhua yam.

Txawm li cas los xij, cov txheej txheem no tsis yog kev sib tsoo lub cev nkaus xwb. Raws li kev sib tsoo, qhov kub thiab txias tshwm sim ntawm qhov abrasive thiab lub workpiece nto. Qhov chaw kub kub no yuav ua rau cov tshuaj hloov pauv hauv cov khoom ntawm qhov chaw ua haujlwm. Piv txwv li, qee cov ntaub ntawv hlau tuaj yeem oxidize nrog oxygen hauv huab cua ntawm qhov kub thiab txias los tsim oxides. Cov oxides no tuaj yeem ua raws li qhov chaw ntawm qhov chaw ua haujlwm, cuam tshuam rau qhov zoo ntawm qhov chaw thiab qhov tseeb ntawm lub workpiece.

Tsis tas li ntawd, lub log sib tsoo nws tus kheej kuj tuaj yeem hloov kho tshuaj lom neeg vim qhov kub thiab txias. Qee cov khoom ntawm cov abrasive tuaj yeem hnov ​​​​mob nrog cov binder, uas ua rau muaj kev hloov pauv ntawm cov qauv ntawm lub log sib tsoo, uas cuam tshuam rau nws txoj kev sib tsoo. Yog li ntawd, xaiv cov kev sib tsoo uas tsim nyog thiab kev sib tsoo tsis zoo los tswj qhov kub thiab txias thaum lub sij hawm sib tsoo yog tus yuam sij kom ntseeg tau tias kev sib tsoo.

Rau cov neeg siv lub log sib tsoo, qhov tseem ceeb ntawm kev nkag siab txog cov tshuaj hloov pauv no yog tias lawv tuaj yeem xaiv hom kev sib tsoo thiab kev sib tsoo tsis zoo raws li cov khoom siv thiab cov kev xav tau ntawm cov khoom siv. Piv txwv li, rau cov khoom siv hlau uas yooj yim oxidized, lub log sib tsoo nrog qhov sib tsoo qis tuaj yeem raug xaiv los txo qhov tshwm sim ntawm cov tshuaj tiv thaiv oxidation. Nyob rau tib lub sijhawm, kev tshuaj xyuas tsis tu ncua thiab kev hloov ntawm kev sib tsoo lub log kuj yog ib qho kev ntsuas tseem ceeb los xyuas kom meej qhov kev sib tsoo.

Hauv cov ntsiab lus, tsis tsuas yog lub cev hloov pauv hauv cov txheej txheem ntawm kev sib tsoo lub workpiece, tab sis kuj muaj tshuaj hloov pauv. Kev nkag siab txog cov tshuaj hloov pauv no pab peb tswj cov txheej txheem sib tsoo zoo dua thiab txhim kho qhov zoo ntawm cov khoom ua haujlwm. Raws li tus neeg siv lub log sib tsoo, peb yuav tsum tau ua tib zoo kawm txog kev paub txog tshuaj lom neeg kom tau txais txiaj ntsig zoo dua hauv kev sib tsoo.

Hauv kev xyaum, cov neeg siv lub log sib tsoo tuaj yeem txhim kho kev sib tsoo los ntawm:

Xaiv lub coolant kom raug: Siv cov coolant zoo tuaj yeem txo qhov kub thiab txias thaum lub sij hawm sib tsoo thiab txo qhov tshwm sim ntawm cov tshuaj hloov pauv. Tus neeg siv tuaj yeem xaiv lub coolant nrog kev ua haujlwm txias txias thiab tiv thaiv oxidation raws li cov khoom siv ua haujlwm thiab kev sib tsoo.

Tswj kev sib tsoo ceev thiab siab: Kev sib tsoo ntau dhau thiab siab yuav ua rau muaj kev sib tsoo kub thiab ua rau muaj kev hloov tshuaj lom neeg ntau ntxiv. Yog li ntawd, tus neeg siv yuav tsum kho qhov sib tsoo ceev thiab siab raws li cov khoom siv ua haujlwm thiab cov yam ntxwv sib tsoo kom ntseeg tau tias muaj kev sib tsoo ruaj khov thiab ua haujlwm zoo.

Kev saib xyuas tsis tu ncua ntawm kev sib tsoo lub log: Sib tsoo lub log yuav maj mam hnav thaum siv, cuam tshuam rau lawv cov kev sib tsoo. Tus neeg siv yuav tsum xyuas qhov hnav ntawm lub log sib tsoo tsis tu ncua thiab hloov lub log sib tsoo hnyav rau lub sijhawm kom ntseeg tau tias kev sib tsoo zoo thiab ua haujlwm tau zoo.

Ua tib zoo saib xyuas ib puag ncig: plua plav thiab tso pa tawm thaum sib tsoo tuaj yeem ua rau muaj kuab paug rau ib puag ncig. Cov neeg siv yuav tsum tau siv cov kev tiv thaiv tsim nyog, xws li txhim kho cov khoom siv tshem tawm plua plav thiab tswj kom muaj cua zoo hauv chaw ua haujlwm, kom txo tau qhov cuam tshuam rau ib puag ncig.

Cov tshuaj hloov pauv hauv kev sib tsoo ntawm lub workpiece tsis tuaj yeem tsis quav ntsej. Cov neeg siv lub log sib tsoo yuav tsum ntxiv dag zog rau kev paub thiab kev nkag siab ntawm cov tshuaj hloov pauv no kom tswj tau cov txheej txheem sib tsoo zoo dua hauv kev ua haujlwm tiag tiag thiab txhim kho qhov zoo ntawm cov khoom ua haujlwm. Nyob rau tib lub sijhawm, los ntawm kev siv cov kev ntsuas tsim nyog thiab cov txheej txheem, cov neeg siv tuaj yeem ua kom zoo dua qhov kev sib tsoo thiab ua tiav cov txiaj ntsig ntau dua thiab cov txiaj ntsig kev lag luam.
