一、晶体定向的基本概念在结晶学上,通常把选择晶体的坐标系统称为晶体定向。然而,在晶体加工中所说的晶体定向在概念上与此稍有不同,它指的是在晶体的坐标系统已经确定的前提下,根据所加工的晶体零件的具体要求,首先测定已知晶体的实际晶面与要求晶面的偏角,进而通过切割或研磨校正这一偏角使之获得准确晶面的过程。 First, the basic concept of crystal orientation In crystallography, the crystal coordinate system is usually called the choice of crystal orientation. However, the definition of crystal orientation in the crystal processing is conceptually different from it, referring to the specific requirements of the crystal component being processed, given that the crystal’s coordinate system has been determined, and the known crystal The actual crystal face and the required crystal face off angle, and then by cutting or grinding correction of this declination to obtain accurate crystal face of the process.
