Pob Zeb Diamond Sib Tsoo Log: Ib Daim Ntawv Qhia Tag Nrho rau Cov Nta, Tech, Cov Zoo & Cov Ntawv Thov

Cov Log Sib Tsoo Pob Zeb Diamond Yog Dab Tsi?

Cov log sib tsoo pob zeb diamond yog cov cuab yeej abrasive uas muaj peb lub ntsiab lus tseem ceeb:

Cov Pob Zeb Diamond Abrasive Grain: Cov khoom siv txiav, ua los ntawm cov pob zeb diamond ntuj (tsis tshua muaj, kim heev) lossis cov pob zeb diamond tsim (feem ntau, tsim los kom sib xws). Cov pob zeb diamond tsim feem ntau raug coated (piv txwv li, nrog nickel lossis titanium) kom txhim kho kev sib txuas rau daim ntawv cog lus thiab tiv taus kev hnav.
Cov Ntawv Sib Txuas: Tuav cov noob pob zeb diamond kom ruaj khov thiab tswj kom cov noob "poob" sai npaum li cas (hnav) thaum siv. Cov hom ntawv sib txuas feem ntau suav nrog cov resin, hlau, vitrified, thiab electroplated (ntau ntxiv txog qhov no hauv ntu Technical Info).
Cov Qauv Qhov: Cov qhov me me ntawm cov ntawv sib txuas thiab cov noob uas tso cai rau cov dej txias ntws, tshem tawm cov chips, thiab tiv thaiv kev txhaws - tseem ceeb rau kev tswj hwm qhov tseeb hauv cov ntawv thov kub siab.

Cov yam ntxwv tseem ceeb ntawm Pob Zeb Diamond Sib Tsoo Log

Cov log sib tsoo pob zeb diamond yog txhais los ntawm cov yam ntxwv uas ua rau lawv zoo tagnrho rau cov ntaub ntawv nyuaj. Nov yog cov tseem ceeb tshaj plaws uas yuav tsum xav txog:

1. Kev Nyuaj Siab thiab Kev Hnav Tsis Zoo

Pob zeb diamond muaj qib 10 ntawm Mohs hardness scale (qhov siab tshaj plaws), uas txhais tau tias nws tuaj yeem sib tsoo cov khoom uas muaj qhov hardness txog li 9 Mohs—xws li alumina ceramics, silicon carbide, iav, thiab tungsten carbide. Tsis zoo li lub log aluminium oxide lossis silicon carbide (uas hnav sai sai rau cov khoom tawv), lub log pob zeb diamond khaws lawv cov duab thiab kev txiav zoo dua 50–100 npaug, txo cov nqi hloov cuab yeej.

2. Kev Muaj Peev Xwm Sib Tsoo Zoo

Nrog cov noob me me li 0.5 μm (micrometers), cov log pob zeb diamond ua tiav qhov chaw tiav du li Ra 0.01 μm - tseem ceeb rau cov khoom siv kho qhov muag, cov khoom siv semiconductor, thiab cov khoom siv kho mob qhov twg txawm tias qhov tsis zoo me me ua rau tsis ua haujlwm.

3. Kev Tiv Thaiv Kub thiab Txias Txiav

Pob zeb diamond muaj qhov thermal conductivity siab dua li tooj liab 5 zaug, ua rau nws yaj sai sai thaum sib tsoo. Qhov no txo qhov "thermal damage" (piv txwv li, tawg, kub hnyiab, lossis cov khoom warping) hauv cov khoom siv uas rhiab heev rau cua sov xws li iav, quartz, thiab cov khoom siv ceramics siab heev.

4. Kev hloov kho tau

Cov chaw tsim khoom kho cov log pob zeb diamond rau cov ntawv thov tshwj xeeb los ntawm kev kho:

Qhov loj ntawm cov noob (ntxhib kom tshem tawm cov khoom sai, zoo rau kev ua tiav).
Hom kev sib txuas (resin rau cov ntawv thov uas tsis kub heev, hlau rau kev sib tsoo hnyav).
Lub log zoo li cas (tiaj, khob, tais, lossis vojvoog) kom phim lub geometry ntawm qhov workpiece.

Cov Ntaub Ntawv Txog Kev Siv: Yuav Ua Li Cas Pob Zeb Diamond Sib Tsoo Log Ua Haujlwm

Yuav kom xaiv tau lub log pob zeb diamond zoo, kev nkag siab txog nws cov lus qhia tshwj xeeb yog qhov tseem ceeb. Hauv qab no yog cov kev cai tseem ceeb tshaj plaws:

1. Hom Kev Sib Txuas: Lub "Backbone" ntawm lub log

Qhov kev sib txuas txiav txim siab qhov ruaj khov ntawm lub log, qhov ceev ntawm kev txiav, thiab qhov haum rau cov ntaub ntawv sib txawv. Nov yog qhov sib piv plaub hom kev sib txuas tseem ceeb:

Hom Nyiaj Txiag	Cov Khoom Tseem Ceeb	Zoo Tshaj Plaws Rau
Cov roj hmab sib txuas	Yooj yim siv, tsis kub heev, txiav sai. Maj mam tawg kom pom cov pob zeb diamond tshiab.	Kev ua tiav cov haujlwm (piv txwv li, iav kho qhov muag, semiconductor wafers), cov ntaub ntawv uas yooj yim raug puas tsuaj los ntawm cua sov.
Kev Sib Txuas Hlau	Muaj zog heev, tsis yooj yim hnav, thiab ruaj khov. Zoo tagnrho rau kev tshem tawm cov khoom hnyav.	Sib tsoo cov hlau tawv (tungsten carbide), pob zeb ua vaj tse, thiab pob zeb. Yuav tsum tau siv dej txias kom tsis txhob kub dhau.
Cov ntawv cog lus vitrified	Kev tiv taus kub siab, kev khaws cia zoo heev, thiab kev txhaws tsawg.	Kev sib tsoo kom raug ntawm cov khoom siv ceramics, cov cuab yeej carbide, thiab cov hlau bearing. Siv rau hauv cov tshuab sib tsoo ceev ceev (HSG).
Kev Sib Txuas Hluav Taws Xob	Txheej sib txuas nyias, ntom ntom nrog cov pob zeb diamond uas pom tseeb. Muab kev txiav zoo tshaj plaws.	Kev sib tsoo profiled (piv txwv li, cov hniav turbine, cov pwm qhov) thiab kev tsim khoom me me.

2. Kev Ntsuas Pob Zeb Diamond

Qhov concentration yog hais txog qhov ntau ntawm cov pob zeb diamond hauv lub log (ntsuas ua carats ib cubic centimeter). Cov concentration feem ntau yog txij li 50% txog 150%:

50–75%: Kev sib tsoo me me (piv txwv li, iav tiav).
100%: Kev sib tsoo dav dav (piv txwv li, cov cuab yeej carbide).
125–150%: Kev sib tsoo hnyav (piv txwv li, pob zeb ua vaj tse, pob zeb).

Kev sib xyaw ua ke ntau dua = lub log ntev dua tab sis tus nqi siab dua.

3. Qhov Loj ntawm Cov Nplej

Qhov loj ntawm cov noob yog muab cim los ntawm tus lej mesh (piv txwv li, 80 # = ntxhib, 1000 # = zoo) lossis micrometer (μm). Txoj cai yooj yim:

Cov noob ntxhib (80 # - 220 #): Tshem tawm cov khoom sai (piv txwv li, ua cov blocks ceramic).
Cov noob nruab nrab (320 # - 600 #): Kev tshem tawm thiab kev ua tiav sib npaug (piv txwv li, kev sib tsoo carbide inserts).
Cov hmoov zoo (800 # – 2000 #): Kev ua tiav zoo (piv txwv li, cov iav tsom iav, cov wafers semiconductor).

4. Ceev ntawm lub log

Lub log pob zeb diamond ua haujlwm ntawm qhov ceev peripheral tshwj xeeb (ntsuas hauv meters ib ob, m/s) los ua kom zoo dua kev ua tau zoo:

Kev sib txuas ntawm cov roj hmab: 20–35 m/s (qis mus rau nruab nrab).
Kev sib txuas ntawm cov hlau: 15–25 m/s (qhov ceev nruab nrab, xav tau cov dej txias).
Vitrified bond: 30–50 m/s (kev kub ceev, zoo tagnrho rau HSG).

Yog tsav ceev tshaj qhov pom zoo ces yuav ua rau lub log tawg lossis cov pob zeb diamond poob tawm.

Cov txiaj ntsig ntawm Pob Zeb Diamond Sib Tsoo Log Dua Li Cov Abrasives Ib Txwm Muaj

Cov log txhuam ib txwm muaj (piv txwv li, txhuas oxide, silicon carbide) pheej yig dua, tab sis lawv tsis ua haujlwm zoo thaum sib tsoo cov khoom tawv lossis cov khoom siv raug. Nov yog vim li cas cov log pob zeb diamond thiaj tsim nyog rau kev nqis peev:

1. Lub Cuab Yeej Siv Tau Ntev Dua

Raws li tau hais ua ntej lawm, cov log pob zeb diamond kav ntev dua li cov log txhuas oxide 50–100 npaug thaum sib tsoo cov khoom tawv. Piv txwv li, lub log pob zeb diamond tuaj yeem sib tsoo 10,000 daim carbide ua ntej yuav tsum tau hloov, thaum lub log txhuas oxide tsuas yog tuav tau 100 daim. Qhov no txo lub sijhawm tsis ua haujlwm rau kev hloov cov cuab yeej thiab txo cov nqi mus sij hawm ntev.

2. Kev Sib Tsoo Zoo Dua

Qhov tawv ntawm pob zeb diamond ua rau nws txiav tau cov khoom siv sai dua li cov khoom siv abrasives ib txwm muaj. Piv txwv li, kev sib tsoo lub phaj alumina ceramic 10mm-tuab nrog lub log pob zeb diamond siv sijhawm 2-3 feeb, piv rau 10-15 feeb nrog lub log silicon carbide.

3. Qhov Zoo Tshaj Plaws

Cov log tsheb ib txwm muaj feem ntau tso "kos" lossis "me me tawg" rau ntawm cov khoom tawv, uas xav tau cov kauj ruam polishing ntxiv. Cov log pob zeb diamond tsim cov xim zoo li daim iav hauv ib zaug dhau, tshem tawm qhov xav tau kev ua tiav tom qab sib tsoo thiab txuag lub sijhawm.

4. Txo Cov Khoom Siv Pov Tseg

Kev sib tsoo kom raug nrog cov log pob zeb diamond txo qhov "sib tsoo ntau dhau" (tshem cov khoom ntau dua li qhov tsim nyog). Qhov no yog qhov tseem ceeb rau cov khoom kim heev xws li semiconductor wafers (qhov twg ib lub wafer tuaj yeem raug nqi $ 1,000+) lossis cov khoom siv kho mob.

5. Kev siv tau ntau yam

Tsis zoo li cov log tsheb ib txwm muaj (uas tsuas yog siv rau cov hlau lossis cov khoom mos xwb), cov log pob zeb diamond sib tsoo ntau yam khoom siv: iav, quartz, ceramics, carbide, pob zeb, pob zeb ua vaj tse, thiab txawm tias cov khoom siv hluavtaws xws li carbon fiber reinforced polymer (CFRP).

Daim Ntawv Thov: Qhov Twg Siv Cov Log Sib Tsoo Pob Zeb Diamond

Cov log sib tsoo pob zeb diamond yog qhov tseem ceeb rau kev lag luam uas xav tau kev ua haujlwm kom raug thiab ruaj khov. Hauv qab no yog lawv cov qauv siv feem ntau:
