CBN可用于銑削含有微量或不含鐵素體組織的軸承鋼或淬硬鋼。高硬度鋼：高硬度鋼（HRC4～7）的高速切削刀具可用金屬陶瓷、陶瓷、TiC涂層硬質(zhì)合金、PCBN等。金屬陶瓷可用基本成分為T(mén)iC添加TiN的金屬陶瓷，其硬度和斷裂韌性與硬質(zhì)合金大致相當(dāng)，而導(dǎo)熱系數(shù)不到硬質(zhì)合金的1/1，并具有優(yōu)異的耐氧化性、抗粘結(jié)性和耐磨性。另外其高溫下機(jī)械性能好，與鋼的親和力小，適合于中高速（在2m/min左右）的模具鋼SKD加工。

直流電機(jī)是指能將直流電能轉(zhuǎn)換成機(jī)械能（直流電動(dòng)機(jī)）或?qū)C(jī)械能轉(zhuǎn)換成直流電能（直流發(fā)電機(jī)）的旋轉(zhuǎn)電機(jī)。它是能實(shí)現(xiàn)直流電能和機(jī)械能互相轉(zhuǎn)換的電機(jī)。當(dāng)它作電動(dòng)機(jī)運(yùn)行時(shí)是直流電動(dòng)機(jī)，將電能轉(zhuǎn)換為機(jī)械能；作發(fā)電機(jī)運(yùn)行時(shí)是直流發(fā)電機(jī)，將機(jī)械能轉(zhuǎn)換為電能。
　　由直流電動(dòng)機(jī)和發(fā)電機(jī)工作原理示意圖可以看到，直流電機(jī)的結(jié)構(gòu)應(yīng)由定子和轉(zhuǎn)子兩大部分組成。直流電機(jī)運(yùn)行時(shí)靜止不動(dòng)的部分稱(chēng)為定子，定子的主要作用是產(chǎn)生磁場(chǎng)，由機(jī)座、主磁極、換向極、端蓋、軸承和電刷裝置等組成。運(yùn)行時(shí)轉(zhuǎn)動(dòng)的部分稱(chēng)為轉(zhuǎn)子，其主要作用是產(chǎn)生電磁轉(zhuǎn)矩和感應(yīng)電動(dòng)勢(shì)，是直流電機(jī)進(jìn)行能量轉(zhuǎn)換的樞紐，所以通常又稱(chēng)為電樞，由轉(zhuǎn)軸、電樞鐵心、電樞繞組、換向器和風(fēng)扇等組成。
　　直流電機(jī)工作原理
　　直流電機(jī)里邊固定有環(huán)狀永磁體，電流通過(guò)轉(zhuǎn)子上的線圈產(chǎn)生安培力，當(dāng)轉(zhuǎn)子上的線圈與磁場(chǎng)平行時(shí)，再繼續(xù)轉(zhuǎn)受到的磁場(chǎng)方向?qū)⒏淖儯虼舜藭r(shí)轉(zhuǎn)子末端的電刷跟轉(zhuǎn)換片交替接觸，從而線圈上的電流方向也改變，產(chǎn)生的洛倫茲力方向不變，所以電機(jī)能保持一個(gè)方向轉(zhuǎn)動(dòng)。
