YHMCNC8326-10數控凸輪軸磨床主要特點 Technical characters
1.采用德國西門子(SIEMENS)840D數控系統。
2.采用靜動*承動平衡高速電主軸（號：ZL2009 2 0063655.8），配置CBN砂輪，實現凸輪軸的80－120米/秒高速磨削。
3.采用高精度高剛度直驅式閉式矩形靜壓導軌（發明公開號：CN201010228669.8），消除了低速爬行現象.
4.工件旋轉軸采用加減速控制方法（發明公開號：CN201010278922.0）（軟件著作權：2010SR004346），提高了磨削精度。
5、砂輪主軸采用內置式在線動平衡。
6.采用金剛石滾輪在線修整CBN砂輪（發明申請號：201110247142.4），提高了機床的加工精度和加工效率。
1.Adopts Germany's Siemens 840D CNC system.
2.Adopts the high-speed spindle bearing（patent No:ZL 2009 2 0063655.8）,with static ant dynamic pressure of balancing, and the CBN grinding wheel to achieve the high-speed grinding for camshaft at80--120 m/s.
3.Use High-precision high-rigidity direct-driving rectangular closed hydrostatic guideways（patent No:CN201010228669.8）,to eliminate the phenomenon of low-speed crawling.
4.The workpiece rotation axis adopts acceleration and deceleration control method（patent NO:201010278922.0）（software copyright:2010SR004346）,to improve the grinding accuracy.
5.The wheel spindle uses the built-in online dynamic balance.
6.Use diamond wheel online for dressing CBN grinding wheel（patents NO:201110247142.4）to improve the machining accuracy and efficiency.
