Xaiv cov kev sib tsoo uas tsim nyog: Xav txog cov ntsiab lus nthuav dav (2)

Tom qab txheeb xyuas koj tus kheej cov kev xav tau, xaiv txoj kev sib tsoo lub log yog ib kauj ruam tseem ceeb los xyuas kom meej tias kev ua haujlwm zoo thiab ua haujlwm tau zoo. Kev xaiv ntawm kev sib tsoo log muaj ntau qhov kev txiav txim siab, suav nrog hom abrasive, hom kev sib cog lus, qhov loj ntawm kev sib tsoo lub log, qhov nyuaj ntawm kev sib tsoo log, qhov porosity (cov ntaub so ntswg), thiab cov concentration uas yuav tsum tau txiav txim siab rau ultra- nyuaj sib tsoo log (pob zeb diamond, CBN sib tsoo log). Nov yog qhov kev txheeb xyuas ntawm cov yam ntxwv no:

abrasive yam

• Corundum (xim av, dawb, chromium, ib leeg siv lead ua, SG, thiab lwm yam) : haum rau cov hlau dav hlau, cam khwb cia hlau thiab lwm yam khoom siv hlau sib tsoo, nrog kev hnav zoo thiab tawv.

• Silicon carbide (dub silicon carbide, ntsuab silicon carbide): feem ntau yog siv nyob rau hauv kev sib tsoo cov ntaub ntawv uas tsis yog-hlau, xws li pob zeb, ceramics, iav, thiab lwm yam., nrog siab hardness thiab brittleness.

• Cubic boron nitride (CBN): tsim nyog rau kev sib tsoo ntawm cov khoom siv tawv tawv thiab cov tawv tawv siab, xws li cov hlau tawv, cov hlau kub ceev, cemented carbide, thiab lwm yam., nrog rau kev hnav tsis kam thiab thermal stability.

• Pob zeb diamond: Tsim nyog rau kev sib tsoo ntawm cov ntaub ntawv nyuaj heev thiab nkig, xws li cemented carbide, ceramics, gems, thiab lwm yam, nrog lub siab tshaj plaws hardness thiab hnav tsis kam.

Bond hom

• Ceramic daim ntawv cog lus: haum rau high-speed sib tsoo thiab hnyav load sib tsoo, zoo tshav kub tsis kam, tsis yooj yim rau deform, tab sis tsis zoo tus kheej-sharpening.

• Resin daim ntawv cog lus: haum rau kev sib tsoo zoo thiab polishing, zoo tus kheej-sharpening, yooj yim rau luas, tab sis tsis zoo cua sov.

• Hlau daim ntawv cog lus: haum rau hnyav load, siab ceev sib tsoo, siab zog, zoo durability, tab sis siab nqi.

• Roj hmab daim ntawv cog lus: haum rau kev sib tsoo ntawm cov ntaub ntawv elastic thiab cov ntaub ntawv tsis yog xim hlau, nrog zoo elasticity thiab poob siab absorbing.

• Plating daim ntawv cog lus: tsis tshua muaj siab sib tsoo efficiency thiab precision. Nws yog tsim rau precision sib tsoo thiab daim iav sib tsoo.

• Brazing daim ntawv cog lus: Haum rau kev ua haujlwm siab, kev sib tsoo ceev, tuaj yeem tiv taus kev sib tsoo loj thiab cuam tshuam. Zoo durability, siab sib tsoo efficiency.

Granularity

Sib tsoo log granularity yog hais txog lub thickness ntawm abrasive hais nyob rau hauv lub sib tsoo lub log, uas txiav txim qhov chaw sib cuag thiab txiav peev xwm ntawm abrasive thiab workpiece nto thaum sib tsoo. Qhov loj ntawm particle ncaj qha cuam tshuam rau kev sib tsoo efficiency, roughness ntawm machined nto thiab kev pab cuam lub neej ntawm lub sib tsoo log.

•Coarse particle loj: loj abrasive hais, siab sib tsoo efficiency, tab sis tsis zoo nto roughness.

• Qhov loj me me: haum rau kev sib tsoo dav dav, suav nrog kev ua haujlwm zoo thiab qhov roughness.

• Fine particle loj: me me abrasive hais, siab nto tiav tom qab sib tsoo, tab sis tsis tshua muaj kev sib tsoo efficiency.

Lub hauv paus ntsiab lus ntawm kev xaiv granularity yog raws li hauv qab no

Raws li cov khoom siv workpiece xaiv:

• Cov hlau mos thiab tawv yuav tsum xaiv cov coarse-grained sib tsoo log.

• Fine grained sib tsoo log yuav tsum tau xaiv rau cov tawv thiab nkig hlau.

Xaiv raws li kev sib tsoo:

• Thaum sib tsoo ntawm kev kub ceev, ib qho abrasive nrog ib qho me me me me me me yuav tsum tau xaiv kom muaj peev xwm txiav txaus.

• Thaum qhov chaw sib cuag ntawm lub log sib tsoo thiab cov khoom ua haujlwm loj, cov abrasive nrog me me particle loj yuav tsum tau xaiv kom dissipate tshav kub thiab txo kev ntxhov siab.

Xaiv raws li qhov yuav tsum tau ua:

• Thaum roughness saum npoo yog siab, zoo-grained sib tsoo log yuav tsum tau xaiv.

• Thaum yuav tsum tau muaj kev ua tau zoo ntau lawm, cov coarse-grained sib tsoo log yuav tsum raug xaiv.

4. Hardness ntawm kev sib tsoo log

• Qib Hardness: los ntawm mos mus rau tawv yog muab faib ua ob peb qib, siab hardness sib tsoo log hnav tsis kam, haum rau kev ua cov ntaub ntawv mos; Kev sib tsoo lub log nrog qis hardness muaj qhov zoo ntawm tus kheej ntse thiab tsim nyog rau kev ua cov ntaub ntawv nyuaj.

• Kev xaiv txoj cai: Raws li lub hardness ntawm workpiece cov ntaub ntawv thiab kev sib tsoo yuav tsum tau, xaiv qhov tsim nyog hardness ntawm lub sib tsoo log los xyuas kom meej kev sib tsoo efficiency thiab ua zoo.

5. Porosity (cov ntaub so ntswg)

• Porosity: sawv cev rau qhov feem pua ​​​​ntawm qhov ntim ntawm porosity nyob rau hauv lub sib tsoo log, uas cuam tshuam rau qhov txias, nti tshem tawm thiab durability ntawm lub log sib tsoo thaum lub sij hawm sib tsoo.

• Lub koom haum naj npawb: qhov siab dua qhov porosity, qhov loj ntawm lub koom haum tooj, lub softer lub sib tsoo log, haum rau kev sib tsoo lub workpiece uas yooj yim rau cua sov thiab deformation; Qhov me me ntawm cov ntaub so ntswg, qhov sib tsoo lub log, haum rau kev sib tsoo hnyav.

6. Concentration (tsuas yog rau super nyuaj sib tsoo log)

• Kev Cuam Tshuam: Qhia qhov feem pua ​​​​ntawm qhov ntim ntawm abrasive nyob rau hauv lub sib tsoo lub log, uas cuam tshuam rau lub durability thiab sib tsoo efficiency ntawm lub log.

• Kev xaiv txoj cai: siab concentration sib tsoo log ntau abrasive, zoo durability, tab sis lub sib tsoo quab yuam loj, yooj yim rau cua sov; Tsawg concentration sib tsoo log tsawg abrasive, sib tsoo quab yuam me me, tsis tshua muaj cua sov, tab sis durability tsis zoo. Xaiv qhov tsim nyog concentration raws li qhov yuav tsum tau ua thiab cov khoom siv ua haujlwm.

7. Lwm yam kev xav

• Cov duab thiab qhov loj me: Xaiv qhov zoo thiab qhov loj ntawm lub log sib tsoo raws li hom khoom sib tsoo thiab kev xav tau.

• Sib npaug thiab raug: xyuas kom meej tias lub log sib tsoo muaj qhov sib npaug zoo thiab raug thaum tig ntawm kev kub ceev kom txo kev vibration thiab suab nrov thiab txhim kho kev ua haujlwm zoo.
