Yuav ua li cas txhawm rau txhim kho kev tsim khoom ntawm pob zeb diamond sib tsoo log

Yuav ua li cas txhawm rau txhim kho kev tsim khoom ntawm pob zeb diamond sib tsoo log?

Qhov twg efficiency los ntawm:

• Nkag siab txog cov ntsiab lus tseem ceeb ntawm kev sib tsoo log

 

Kev ua haujlwm siab yog pom nyob rau hauv cov ntaub ntawv tshem tawm sai dua, kev pab cuam lub neej ntev dua, luv luv downtime rau kev hloov, thiab zoo dua saum npoo zoo. Tag nrho cov no yog txiav txim siab los ntawm ntau yam tseem ceeb ntawm kev sib tsoo log:

 

1. Abrasive hom- cov no yog "cov hniav" ntawm lub log sib tsoo

• Brown corundum (A): Muaj zog universality, haum rau carbon steel, alloy steel, thiab lwm yam., nrog cov nqi siab -effectiveness.
• Dawb corundum (WA): siab dua hardness, zoo tus kheej sharpening, haum rau quenched steel thiab siab -ceev steel, nrog tsawg sib tsoo kub.
• Silicon carbide (C/GC): ntse thiab tawv, haum rau cov alloys nyuaj, tsis yog -ferrous hlau (xws li txhuas, tooj liab), thiab tsis yog - cov ntaub ntawv hlau.
• Ceramic alumina (SG): Nrog rau cov qauv microcrystalline, nws yog hnav- tiv taus thiab tswj kev ntse, nrog rau lub neej ntev heev, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm hnyav- kev sib tsoo.
• Cubic boron nitride (CBN) thiab pob zeb diamond (D): superhard abrasives siv rau kev ua haujlwm nyuaj rau cov khoom siv xws li cov alloys nyuaj, ceramics, thiab siab - steel ceev, nrog lub neej ntev heev tab sis tus nqi siab.
• Cov lus qhia ua haujlwm tau zoo: Kev sib txuam abrasives nrog cov ntaub ntawv ua haujlwm yog thawj kauj ruam. Xaiv qhov tsis ncaj ncees lawm abrasive tuaj yeem ua rau kev sib tsoo tsis ua haujlwm, hlawv ntawm qhov chaw ua haujlwm, lossis hnav nrawm ntawm lub log sib tsoo, ua rau kev sib tham tsis zoo.

 

2. Granularity- txiav txim siab qhov tuab ntawm "cov hniav"

• Coarse grained (xws li 24 # -46 #): Muaj zog txiav quab yuam, siab cov khoom tshem tawm tus nqi, tab sis qhov nto kuj ntxhib. Haum rau kev sib tsoo ntxhib thiab ua kom zoo deburring.
• Nruab nrab particle loj (xws li 60 # -100 #): universal ntau, ntsuas efficiency thiab nto zoo.
• Fine grained (xws li 120 # thiab finer): siv rau precision sib tsoo thiab polishing kom tau ib tug du nto, tab sis nrog ib tug qis dua tus nqi tshem tawm.
• Cov lus qhia ua haujlwm tau zoo: Thaum ua tau raws li qhov yuav tsum tau ua, xaiv coarser particle loj npaum li sai tau tuaj yeem txhim kho kev tshem tawm tau zoo.

 

3. Hardness- yog hais txog lub zog ntawm cov khoom abrasive tswj los ntawm tus neeg sawv cev sib txuas

• Cov mos mos dhau lawm: Cov khoom abrasive poob ntxov dhau, lub log sib tsoo hnav sai sai, cov duab tsis yooj yim los tswj, thiab hloov zaus nce.
• Ib qho nyuaj heev: Cov khoom abrasive tsis poob tawm tom qab passivation, ua rau nws tus kheej tsis zoo sharpening thiab muaj zog sib tsoo, cua kub hnyav, uas yuav hlawv cov workpiece thiab txo efficiency.
• Qhov zoo tshaj plaws hardness yog thaum cov khoom abrasive poob rau hauv ib lub sij hawm thaum lub sij hawm passivation, exposing tshiab ntse abrasive hais thiab tswj kev nruam thiab muaj peev xwm txiav.
• Cov Lus Qhia Txog Kev Ua Haujlwm: Rau kev sib tsoo zoo (xws li kev sib tsoo tiaj tus thiab tsis muaj kev sib tsoo), xaiv lub log sib tsoo uas yog me ntsis nyuaj dua li cov pa tawv tawv, uas tuaj yeem tuav cov duab thiab ruaj khov nyob rau hauv siab thiab txhim kho tag nrho kev ua haujlwm.
   

 

 

4. Lub koom haum thiab binders- "skeletal structure" ntawm kev sib tsoo log

• Lub koom haum (looseness ntawm abrasive particle tis): Lub koom haum nruj yog hnav- tiv taus, lub koom haum xoob tau tshem tawm cov nti zoo, ceev cua sov dissipation, thiab tsis yooj yim los thaiv. Kev sib tsoo zoo feem ntau yuav tsum tau tshem tawm cov nti zoo thiab ua kom sov, yog li qhov nruab nrab rau cov qauv xoob yog ib qho kev xaiv.
• Bonding agent: Feem ntau siv ceramic bonding agent (V) muaj kev ruaj ntseg zoo thiab corrosion kuj; Resin binder (B) muaj elasticity, poob siab tsis kam, thiab yog haum rau precision sib tsoo thiab txiav; Hlau sib txuas tus neeg sawv cev (M) muaj lub zog siab thiab feem ntau yog siv hauv superhard abrasive sib tsoo lub log
