Abrasivehardness yog hais txog qhov nyuaj ntawm cov abrasive hais nyob rau saum npoo ntawm lub abrasive kom poob tawm nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, uas yog, lub firmness ntawm lub abrasive binding tus neeg saib xyuas tuav lub abrasive hais. , lub hardness ntawm abrasive yuav tsawg, thiab vice versa, hardness yuav siab.
Qhov kev xaiv ntawmabrasivehardness feem ntau txiav txim siab qhov kev sib tsoo efficiency thiab qhov zoo ntawm cov txheej txheem nto.Cov abrasive yog xaiv tau zoo, cov blunt abrasive hais tsis yooj yim rau poob, lub sib tsoo log yog yooj yim rau clog, sib tsoo kub nce, thiab lub workpiece yog ib qho yooj yim mus hlawv, uas cuam tshuam rau qhov zoo ntawm lub workpiece.Kev sib tsoo efficiency yog tsawg.Yog tias cov abrasive raug xaiv mos dhau lawm, cov khoom abrasive yuav poob tawm thaum lawv tseem ntse, uas ua rau kom poob ntawm cov cuab yeej abrasive, thiab tib lub sijhawm nws yooj yim los plam qhov tseeb abrasive geometry, uas cuam tshuam rau kev ua haujlwm raug ntawm lub workpiece, yog li kev xaiv ntawm abrasive hardness yuav tsum yog nruab nrab.Qhov kev sib raug zoo ntawm abrasive hardness thiab nto roughness yog pom nyob rau hauv daim duab 9.
Daim duab Qhov kev sib raug zoo ntawm abrasive hardness thiab nto roughness
(1) Thaum sib sau, sib tsoo thiab sib tsoo ntawm qhov chaw sib tshuam, lub hardness ntawm abrasive yuav tsum siab dua.
(2) Lub hardness ntawm lub cuab yeej abrasive yuav tsum softer thaum lub dav hlau sib tsoo, thiab lub hardness ntawm lub cuab yeej abrasive yuav tsum softer thaum kawg lub ntsej muag sib tsoo zoo dua li ntawm qhov sib tsoo.
(3) Lub hardness ntawm cov cuab yeej abrasive xaiv rau sab hauv lub voj voog sib tsoo yog siab dua li ntawm lub voj voog sab nrauv thiab dav hlau sib tsoo.
(4) Thaum cov cuab yeej ntse ntse, xaiv cov cuab yeej mos mos.
(5) Lub hardness ntawm high-speed sib tsoo abrasives yog 1-2 qib qis dua li cov sib tsoo zoo tib yam.
Abrasive hardness xaiv txoj cai:
(1) Thaum sib tsoo cov ntaub ntawv nyuaj, xaiv cov abrasives softer, thiab thaum sib tsoo cov ntaub ntawv mos, xaiv cov tawv abrasives.
(2) Thaum sib tsoo mos thiab tawv cov ntaub ntawv uas tsis yog-ferrous hlau, hardness yuav tsum softer.
(3) Rau kev sib tsoo cov ntaub ntawv uas tsis zoo thermal conductivity (alloy steel, cemented carbide, thiab lwm yam), softer abrasives yuav tsum tau xaiv.
Kev xaiv ntawmabrasivehardness raws li kev sib tsoo sib txawv
Lub hardness ntawm lubabrasivecov cuab yeej siv rau kev txiav thiab sib tsoo lub voj voog sab nrauv yog softer dua li ntawm lub voj voog sab nrauv siv rau kev sib tsoo longitudinal pub.Txoj kev txiav grinds workpieces nrog siab geometric zoo li yuav tsum tau xws li cov ces kaum me, arcs los yog txoj cai kaum, thiab busbars, thiab hardness ntawm cov cuab yeej abrasive yog 1-2 qib siab dua.
