Thaum nws los txog rau qhov kev sib tsoo kom zoo, cbn (cubic boron nitride) sib tsoo log yog qhov kev xaiv zoo rau ntau cov ntawv thov. Cov cuab yeej siv siab no muaj cov yam ntxwv tshwj xeeb muaj cov yam ntxwv zoo uas ua rau lawv xaiv qhov kev sib tsoo uas nyiam tshaj plaws rau ntau txoj kev sib tsoo. Hauv cov blog no, peb yuav tshawb cov yam ntxwv tseem ceeb ntawm CBN sib tsoo lub log thiab nkag siab vim li cas lawv tau saib xyuas kev lag luam.
Siab tawv thiab tawv:
CBN sib tsoo lub log yog lub npe rau lawv cov kev nyuaj siab thiab tawv. Qhov no tso cai rau lawv tswj hwm lawv txoj kev txiav caj dab thiab kev ncaj ncees txawm tias thaum raug cov kev sib tsoo siab thiab ua haujlwm hnyav. Raws li qhov tshwm sim, lawv xa cov kev sib tsoo thiab meej haum, ua rau lawv zoo rau kev ua haujlwm machining.
Kev kub siab ua hauj thiab zoo thermal stability:
Ib qho ntawm cov khoom seem ntawm CBN sib tsoo cov log yog lawv qhov kub siab tiv thaiv thiab zoo thermal stability. Qhov no ua rau lawv tswj tau lawv txoj kev txiav kev ua haujlwm kub, ua rau lawv haum rau kev sib tsoo nrawm nrawm. Lawv lub peev xwm tiv thaiv tshav kub kuj tseem me me qhov kev pheej hmoo ntawm kev puas tsuaj thermal rau lub workpiece, kom ntseeg tau tias lub tshuab hluav taws xob tsis pub dawb los ntawm kev txawv txav metallorgalities.
Muaj zog tshuaj inertness:
CBN sib tsoo cov log pom kev nthuav qhia cov tshuaj lom neeg ua kom muaj zog, ua rau lawv tiv taus tshuaj lom neeg nrog cov khoom siv. Tus yam ntxwv sib tsoo no tau sib tsoo nyob ruaj khov thiab tsis cuam tshuam los ntawm cov khoom siv ua haujlwm, yog li txuas tau nws lub neej thiab khaws cia kev txiav txim siab.
Cov ris muaj zog tsis kam thiab ntev kev pabcuam lub neej:
Nrog lawv qhov tshwj xeeb hnav tsis kam, CBN sib tsoo cov log muaj lub neej pabcuam txuas ntxiv, txo qhov ntau ntawm cov log hloov thiab downtime. Qhov no txhais cov khoom lag luam thiab cov nqi txuag tau rau tus neeg siv, ua rau lawv xaiv tau nqi-siv rau kev tsim khoom lag luam.
Zoo thermal conductivity:
Qhov zoo thermal conductivity ntawm CBN sib tsoo cov log sib tsoo kom muaj cua kub ua kom muaj kev sib tsoo, tiv thaiv kev puas tsuaj thermal thiab ua kom muaj kev sib tsoo sib tsoo dua.
Hauv kev xaus, cov yam ntxwv ntawm CBN sib tsoo log teeb lawv ua qhov kev xaiv tshwj xeeb rau cov ntawv thov kev sib tsoo. Los ntawm lawv lub siab tawv thiab tawv rau lawv cov kev hnav zoo heev, CBN sib tsoo log muaj cov yeeb yam sib xyaw ua ke uas ua rau lawv tsis tseem ceeb hauv kev tsim khoom lag luam.
