数控车削主要加工对象是哪些

  一、要求高的回转体零件

  1:精度要求高的零件

  由于数控车床的刚性好,制造和对刀精度高,以及能方便和精确地进行人工补偿甚至自动补偿,所以它能够加工尺寸精度要求高的零件。一般来说,车削七级尺寸精度的零件应该没什么困难。在有些场合可以以车代磨。此外由于数控车削时刀具运动是通过高精度插补运算和伺服驱动来实现的,再加上机床的刚性好和制造精度高,所以它能加工对母线直线度、圆度、圆柱度要求高的零件。对圆弧以及其它曲线轮廓的形状,加工出的形状与图纸上的目标几何形状的接近程度比仿形车床要好得多。车削曲线母线形状的零件常采用数控线切割加工并稍加修磨的样板来检查。数控车削出来的零件形状精度,不会比这种样板本身的形状精度差。数控车削对提高位置精度特别有效。不少位置精度要求高的零件用传统的车床车削达不到要求,只能用尔后的磨削或其它方法弥补。车削零件位置精度的高低主要取决与零件的装夹次数和机床的制造精度。在数控车床上加工如果发现位置精度较高,可以用修改程序内数据的方法来校正,这样可以提高其位置精度。而在传统车床上加工是无法作这种校正的。数控车削主要加工对象是哪些图
