Kev cuam tshuam ntawm brittleness thiab toughness ntawm abrasive ntawm kev sib tsoo workpiece ntawm kev sib tsoo log

Lub brittleness thiab toughness ntawm abrasives muaj qhov cuam tshuam loj rau cov txheej txheem sib tsoo thiab qhov zoo ntawm cov khoom siv thaum lub sij hawm sib tsoo cov txheej txheem sib tsoo. Abrasives yog ib qho tseem ceeb ntawm kev sib tsoo lub log, thiab lawv cov khoom ncaj qha txiav txim siab qhov kev sib tsoo thiab qhov zoo ntawm lub workpiece.

Lub tswv yim thiab qhov sib txawv ntawm brittleness thiab toughness ntawm abrasives:

Abrasives 'brittleness: Brittleness yog hais txog cov cuab yeej ntawm cov khoom uas nquag tawg lossis tawg nyob rau hauv kev ua ntawm sab nraud quab yuam. Rau abrasives, brittleness yog manifested raws li qhov yooj yim ntawm kev tawg mus rau hauv finer hais thaum lub sij hawm sib tsoo txheej txheem. Cov khoom no tuaj yeem ua rau thaj tsam sib tsoo, txhim kho kev sib tsoo. Txawm li cas los xij, ntau dhau ntawm brittleness kuj tseem tuaj yeem ua rau tawg ntxov ntawm cov khoom abrasive, cuam tshuam rau kev ua haujlwm ntev thiab kev ruaj ntseg ntawm lub log sib tsoo.

Abrasives 'toughness: Toughness yog qhov tseem ceeb ntawm qhov sib txawv ntawm brittleness. Nws yog hais txog lub peev xwm ntawm cov khoom siv los tiv thaiv kev puas tsuaj thiab tswj nws cov duab thiab qhov loj me stability nyob rau hauv qhov kev txiav txim ntawm sab nraud rog. Nyob rau hauv abrasives, toughness yog manifested raws li lub peev xwm ntawm abrasive hais kom muaj ib tug tej yam kev mob ntawm kev ncaj ncees thiab lub zog thaum raug hnav thiab cuam tshuam, ncua kev pab cuam lub neej ntawm lub sib tsoo log. Abrasives nrog zoo toughness tuaj yeem tiv taus hnav thiab tawg, tswj cov duab thiab precision ntawm kev sib tsoo log.

Qhov cuam tshuam ntawm abrasives ' brittleness thiab toughness ntawm kev sib tsoo ntawm workpieces:

Kev cuam tshuam ntawm brittleness:

Txhim kho kev sib tsoo kom zoo: Abrasives nrog ntau dua brittleness yog qhov yooj yim rau tawg rau hauv cov khoom zoo dua thaum lub sij hawm sib tsoo, uas tuaj yeem ua rau thaj tsam sib tsoo, txhim kho kev sib tsoo. Qhov no tso cai rau kom tshem tawm cov khoom sai dua ntawm qhov chaw ua haujlwm, txo lub sijhawm ua haujlwm.

Muaj feem cuam tshuam rau kev sib tsoo zoo: Txawm li cas los xij, cov brittleness ntau dhau kuj tuaj yeem ua rau cov khoom abrasive tawg ua ntej, ua rau cov duab tsis zoo. Cov khoom tsis zoo no tuaj yeem tsim cov txiav tsis ruaj khov thaum sib cuag nrog cov khoom ua haujlwm, ua rau khawb lossis tsis sib xws ntawm qhov chaw ua haujlwm.

Kev cuam tshuam ntawm toughness:

Txhawm rau tswj cov duab ntawm lub log sib tsoo, cov abrasives nrog zoo toughness tuaj yeem tiv taus hnav thiab cuam tshuam zoo, uas ua rau muaj kev tswj xyuas cov duab thiab qhov ntev ntawm kev sib tsoo log. Qhov no ua kom cov precision thiab sib xws nyob rau hauv cov txheej txheem sib tsoo, thaum kawg txhim kho qhov zoo ntawm workpiece. Tsis tas li ntawd, ntau dua toughness ncua lub neej ntawm lub log sib tsoo los ntawm kev txo cov pob txha thiab detachment ntawm abrasive hais, uas slows down lub coj tus nqi ntawm lub log. Yog li ntawd, qhov no txo ​​qhov zaus thiab tus nqi cuam tshuam nrog kev hloov cov log sib tsoo.

Lub brittleness thiab toughness ntawm abrasives muaj qhov cuam tshuam tseem ceeb ntawm cov txheej txheem thiab qhov tshwm sim ntawm kev sib tsoo workpieces. Thaum xaiv cov abrasives, nws yog ib qho tsim nyog yuav tsum sib npaug ntawm kev sib raug zoo ntawm brittleness thiab toughness raws li kev ua haujlwm tshwj xeeb thiab cov khoom siv ntawm lub workpiece. Rau cov khoom ua haujlwm uas yuav tsum tau tshem tawm cov khoom siv tau zoo, abrasives nrog siab dua brittleness tuaj yeem raug xaiv kom tsim nyog los txhim kho kev sib tsoo; rau workpieces uas yuav tsum tau siab precision thiab zoo ua, abrasives nrog zoo toughness yuav tsum tau xaiv los xyuas kom meej stability thiab precision ntawm kev sib tsoo.Los ntawm tsim nyog xaiv abrasives thiab optimizing sib tsoo txheej txheem tsis, npaum thiab zoo sib tsoo log sib tsoo ua tiav.
