Machining Boron Nitride Ceramic

Machining Boron Nitride Ceramic, tseem hu ua WHITE GRAPHITE, yog ib qho fo ob nrov tshuab ua ceramic, lwm qhov yog Machinable iav Ceramic. Lub Mohs hardness ntawm Boron Nitride tsuas yog 2-3, ib qho ntawm cov tshuab tau txiav iav yog li ntawm 4-5, yog li boron nitride ntau ntau softer thiab yooj yim ua tiav. Boron nitride muaj kev sib xyaw ua ke hauv kev siv tshuaj, hluav taws xob thiab cov khoom siv ua lub siab li sintered advanced technical ceramics. Machinable boron nitride siv nyob rau hauv qhov ntau ntawm cov kev lag luam siab. Cov no suav nrog kev ua haujlwm siab cov tshuab hluav taws xob kub, kev tsim khoom lag luam ceramic thiab kev lag luam semiconductor.

Qhov boron nitride machinable ceramic yog tshwm sim los ntawm unidirectional kub nias. Lub tiaj tus hlau hexagonal qauv siv hluav taws xob ua ke yog ua tiav nrog kub nias. Cov atoms ntawm lub platelet dav hlau tau tuav los ntawm covalent daim ntawv cog lus nyob rau hauv kev kho hexagonal, uas ua rau muaj txiaj ntsig zoo ntawm lub cev, thermal thiab hluav taws xob ua yeeb yam. Nruab nrab ntawm cov khaubncaws sab nraud povtseg uas nyob ib sab, thiaj li hu ua Van der Waals txoj hlua khi hu ua, uas ua kom lub nrawm zoo.

Peb cov tshuab machining hexagonal boron nitride chav kawm yog cov khoom lag luam tsim tau. Lawv tuaj yeem tau yooj yim milled thiab tig nrog HSS lossis VHM cov cuab yeej. Cov lag luam muaj cov kais dej txaus rau cov xov. Cov kev ua yuav tsum ib txwm ua kom qhuav. Yuav tsum khaws cov txiav kom tu thiab kom huv. Tsis txhob siv cov ces kaum kev txiav tsis zoo. Raws li kev taw qhia txog kev ua machining boron nitride, thov lav tus ceev spindle ntawm 1,000-2,000 rpm thiab pub mov ntawm 0.25-0.75 mm / U.
