求翻译：凸轮轴磨床的机械设计及逻辑控制，数控CBN凸轮轴磨床具有高精度、到效率、高柔性、工序集中等特点，几经逐步在现在汽车工业中得到应用。国内已对数控CBN凸轮轴磨削加工方法进行进一步研究，并研制出了部分样机，但从目前的研究状况来看，大多处于实验阶段，磨削加工精度还不能满足实际生产应用的要求，很难实现商品化。因此，本文对该类型磨床进行初步的研究。是什么意思？

Camshaft grinding machines-mechanical design and logic control, CNC CBN camshaft grinding machine with high precision, high efficiency, flexible, process centralization, and so on, after progressive application in the automobile industry has been now. Domestic on CBN camshaft CNC grinding machining method for further research, and developed some prototypes, but judging from the present research situation, most of them are in the experimental stage, production and application of grinding accuracy does not meet the actual requirements, it is difficult to achieve commercialization. Therefore, this article on the type of grinding machines for initial research.
