1.Characters ti CA ṣe nipasẹ Sol-jeli ọna

CA, yi ni Sol-jeli ọna, ni a irú ti sintered abrasive oka. Ki o ti wa ni tun daruko bi SG abrasive ọkà. Awọn gara apa miran jẹ gidigidi kekere, ti o jẹ nikan 100-500nm, ati awọn ti o jẹ nikan kere ọkan-ogorun ti o wọpọ corundum gara iwọn. A nkan ti 46 # ọkà ni ọkẹ àìmọye ti gara patikulu. Nigba ti lilọ, awọn oka ti ibile itanna dapo alumina di alapin ati deactive, ati irọrun wa ni pipa lati abrasive irinṣẹ labẹ awọn lilọ agbara. Awọn oniwe-iṣẹ aye ni kikuru. Sibẹsibẹ, fun CA, ie SG abrasive oka, gbogbo wọ ilana jẹ tun awọn oniwe-ara-sharpening ilana. Nigba awọn oniwe-iṣẹ aye, titun eti lilọ eti ṣi nigbagbogbo nigbati passivating itanran gara oka wa ni pipa lati awọn lilọ irinṣẹ labẹ awọn lilọ agbara, eyi ti o mu ki awọn oka nigbagbogbo ni didasilẹ ipo. Nítorí, awọn abrasive irinṣẹ ṣe nipa CA ni o wa ti gun aye iye, ti o dara ara-sharpening agbara, ga Ige ṣiṣe, bi daradara bi ko sisun workpieces.

Nitori awọn oniwe-o yatọ si microstructure, CA fihan iyato on abrasive oka egugun ihuwasi. CA fihan pẹlú awọn gara egugun bibajẹ, nigba ti ibile itanna dapo alumina fihan transgranular egugun bibajẹ. Nitorina, awọn toughness ti CA ni lemeji ju ti o ti awọn ti o wọpọ dapo alumina.

CA yi ni Sol-jeli ọna ni iru kemikali tiwqn ati lile to WFA (White dapo Alumina). Nitori awọn oniwe-aṣọ aami microcrystalline be, ga toughness ati awọn aami baje išẹ, CA le ti wa ni o gbajumo ni lilo fun lilọ ti soro-to-ilana ohun elo bi ọpa irin, alakikanju alagbara, irin, ooru-sooro alloy, irin, ati bẹbẹ lọ

 2.Features ti abrasive irinṣẹ ṣe nipa CA

(1)  The oka ni o wa gidigidi didasilẹ, eyi ti o mu ki o ni o ni lagbara Ige agbara, ga lilọ ṣiṣe. O le ṣee lo fun tobi jin Ige, roughing kikọ sii, eru ojuse ati ki o ga ṣiṣe lilọ. Ni ibamu si awọn ṣàdánwò, nikan ilana ono le de ọdọ 0.3mm tabi diẹ ẹ sii, irin yiyọ oṣuwọn jẹ diẹ sii ju lemeji ti o wọpọ corundum lilọ wili.

(2) O dara toughness, kekere abrasion, ati lilọ kẹkẹ pẹlu ti o dara apẹrẹ idaduro. Fun konge lilọ ati fọọmu lilọ, ti o ga onisẹpo yiye ati iwọn apẹrẹ aitasera le wa ni irọrun ni.

(3) Ga agbara ati ki o gun iṣẹ aye. O le de ọdọ 5 to10 igba ti o wọpọ corundum lilọ wili. Low rirọpo igbohunsafẹfẹ le din oluranlowo processing akoko ati downtime, eyi ti o mu ki o conducive si awọn lilo ti ìtúwò Iṣakoso laifọwọyi ẹrọ, mimo laifọwọyi gbóògì.

(4) Ti o dara ara-sharpening išẹ, ko clogging. O le pa duro lilọ išẹ, din atunse (nikan nipa 1/3 ti awọn ti o wọpọ corundum lilọ wili) ki o si mu gbóògì ṣiṣe.

(5) Ni lilọ išẹ, CA lilọ wili ni o wa jina dara ju wọpọ corundum lilọ wili. Fun owo, CA jẹ Elo kekere ju CBN ati Diamond Abrasives, nigba ti awọn oniwe-líle ni iru si wipe ti o wọpọ dapo alumina, eyi ti o mu ki o ko nilo pataki lilọ awọn ẹrọ ati atunse ti awọn ẹrọ. Ki o ni o ni ko si pataki ibeere fun lilọ awọn ẹrọ ko si si tun isoro akawe si CBN ati Diamond Abrasives. O tun ni o ni ko si pataki ibeere fun lilọ-ọmọ. Nítorí, o jẹ rorun lati tan awọn lilo ti o.
