Yuav ua li cas xaiv lub taub hau txheej txheem?

1. Pob zeb diamond granularity xaiv

Thaum lub pob zeb diamond particle loj yog tuab thiab ib leeg-grained, lub taub hau taub hau yog ntse thiab sawing efficiency siab, tab sis lub zog dabtsi yog khoov ntawm pob zeb diamond blocks yog txo, thiab thaum lub pob zeb diamond particle loj yog zoo los yog ntxhib particle loj sib tov, lub taub hau yog ruaj. tab sis tsawg npaum li cas. Noj cov ntsiab lus saum toj no rau hauv tus account, nws yog qhov tsim nyog los xaiv pob zeb diamond granularity ntawm 50/60.

2. Kev xaiv ntawm pob zeb diamond faib concentration

Nyob rau hauv ib tug tej yam ntau yam, thaum lub pob zeb diamond concentration hloov ntawm qis mus rau siab, lub sharpness thiab sawing efficiency ntawm lub sawb maj mam txo, thiab cov kev pab cuam lub neej yog maj mam ncua; Nrog qis concentration thiab ntxhib grain loj, qhov ua tau zoo yuav raug txhim kho. Siv cov teebmeem sib txawv ntawm kev txiav ntawm ntau qhov chaw ntawm lub taub hau, qhov sib txawv ntawm qhov sib txawv (piv txwv li qhov qis dua tuaj yeem siv rau hauv nruab nrab txheej ntawm peb txheej lossis ntau txheej txheej), qhov nruab nrab zawj yog tsim los ntawm cov cuab yeej ua haujlwm thaum lub sijhawm sawing. , uas yog qhov zoo rau kev tiv thaiv cov hniav skew, yog li kev txhim kho pob zeb ua haujlwm zoo.

3. Pob zeb diamond zog xaiv

Lub zog ntawm pob zeb diamond yog qhov ntsuas tseem ceeb los xyuas kom meej qhov kev ua tau zoo. Lub zog ntau dhau yuav ua rau cov siv lead ua tsis yooj yim tawg, kev sib tsoo cov khoom siv yog polished, sharpness txo, ua rau cov cuab yeej ua haujlwm tsis zoo; Yog li, qhov kev siv zog yuav tsum tau xaiv ntawm 130 txog 140N.

4. Kev xaiv ntawm kev sib khi theem

Qhov kev ua tau zoo ntawm cov hniav nyob ntawm tsis yog pob zeb diamond nkaus xwb, tab sis ntawm kev ua tau zoo tag nrho ntawm cov khoom sib xyaw xws li lub taub hau uas lub pob zeb diamond thiab cov ntaub ntawv sib txuas kom zoo. Rau cov pob zeb mos xws li marble, kev ua haujlwm hydraulic ntawm lub taub hau yog qhov tsawg, thiab cov khoom siv tooj liab yog muaj. Txawm li cas los xij, tooj liab-raws li binder sintering kub yog tsawg, lub zog, hardness yog tsawg, toughness yog siab, thiab lub binding zog ntawm pob zeb diamond yog tsawg. Thaum tungsten carbide (WC) ntxiv, WC los yog W2C yog siv los ua cov pob txha hlau, nrog rau qhov tsim nyog ntawm cobalt los txhim kho lub zog, hardness thiab binding yam ntxwv, thiab ib tug me me ntawm melting point, tsawg hardness Cu, Sn, Zn. thiab lwm yam hlau rau kev sib txuas theem. Lub granularity ntawm lub ntsiab ntxiv yuav tsum zoo nyob rau hauv 200, thiab cov granularity ntawm cov khoom xyaw ntxiv yuav tsum zoo nyob rau hauv 300.

5. Kev xaiv cov txheej txheem sintering

Nrog rau qhov nce ntawm qhov kub thiab txias, qhov ceev ntawm lub log tsheb lub cev nce, qhov kev tiv thaiv rau kev khoov kuj nce, thiab nrog rau kev ncua sij hawm ntawm lub rwb thaiv tsev, lub zog ntawm lub cev tsis muaj zog ntawm lub cev thiab pob zeb diamond block yog nce thiab tom qab ntawd txo cov txheej txheem sintering 120s. tuaj yeem xaiv ntawm 800 ° C kom ua tau raws li qhov yuav tsum tau ua.
