Lub tshuab ua haujlwm ntawm pob zeb diamond- xaj cov hniav.

Nyob rau hauv cov txheej txheem tsim khoom ntawm pob zeb diamond saw hniav, ob peb kauj ruam yog siv, nrog rau kev sib xyaw pob zeb diamond thiab hlau hmoov, granulation, sib sau, sintering, thiab lwm yam. Pob zeb diamond yog randomly faib nyob rau hauv matrix, uas yog nquag mus tsub zuj zuj thiab segregation, uas ua rau tsis txaus tuav ntawm matrix ntawm lub pob zeb diamond nyob rau hauv lub pob zeb diamond tsub zuj zuj ntawm cheeb tsam, thiab detachment ntawm cov pob zeb diamonds thiab detachment. thiab detachment ntawm pob zeb diamond.

 

Raws li qhov tsis zoo ntawm cov pob zeb diamond saw hniav tsim cov txheej txheem, peb lub tuam txhab tau txhim kho thiab tsim thev naus laus zis ntawm pob zeb diamond txiav txim, thiab tsim thiab tsim cov pob zeb diamond txiav txoj kev pom cov hniav, phab ntsa pom hniav, nplhaib saw hniav, thiab pob zeb diamond steel - pob zeb diamond txiav cov khoom siv.

 

Tus yuam sij rau lub thev naus laus zis no yog tswj cov pob zeb diamond hais rau ntawm qhov txiav ntawm cov saw hniav kom tsim ib qho V- zoo li lub kaum sab xis txiav (lub kaum sab xis yog nruab nrab ntawm 15 txog 60 degree, saib daim duab 1). Thaum lub sij hawm txiav, cov khib nyiab uas tsim los ntawm ob lub pob zeb diamond hais nyob rau pem hauv ntej ntawm V-puab flushes lub pob zeb diamond hais nyob rau tom qab ntawm V-puab, yog li ua rau cov pob zeb diamond hais rau ntawm lub saw hniav kom protrude sai, ua rau lub siab txiav ceev rau cov saw hniav.

 

 

Cov pob zeb diamond raug faib los ntawm txheej txheej ntawm ib ntus raws qhov siab ntawm cov saw hniav. Thaum lub qhov siab ntawm lub pob zeb diamond nyob rau hauv kab dhau los mus txog 1/3 ntawm pob zeb diamond particle loj, lub pob zeb diamond nyob rau hauv kab tom ntej pib protrude. Cov txheej txheem no yog rov ua kab los ntawm kab, raws li qhia hauv daim duab 2. Qhov kev npaj no tso cai rau cov matrix los tiv thaiv cov embedded nto ntawm kab yav dhau los ntawm cov pob zeb diamond, ncua lub pob zeb diamond tsis ua hauj lwm. Lub voj voog no txuas ntxiv mus txog thaum kawg txheej ntawm pob zeb diamond raws li qhov siab ntawm cov saw hniav tau noj, yog li tswj xyuas qhov ntse ntawm cov hniav ntawm qhov pib mus rau qhov kawg thiab ua tiav lub neej ntev. Kev tswj tau thiab tsis sib xws ntawm cov pob zeb diamond nyob rau hauv cov saw hniav ua kom muaj kev ua haujlwm siab thiab kev ruaj ntseg thoob plaws hauv tag nrho cov txheej txheem txiav, txo qis kev siv zog thiab suab nrov.
