电主轴技术与发展趋势
数控机床将高效、高精度和高柔性集为一体。同时为了得到高生产率，以及为了提高加工精度，高速的加工技术也越来越收到业内的重视。
    超高速数控机床是实现超高速加工的物质基础，而高速主轴又是超高速数控机床的“核心”部件，它的性能直接决定了机床的超高速加工性能，它不但要求较高的速度精度，而且要求连续输出的高转矩能力和非常宽的恒功率运行范围。因此，具备相应的高转速和高精度、高速精密和高效率特性的数控机床电主轴应运而生。电主轴具有结构紧凑、重量轻、惯性小、动态特性好等优点，并可改善机床的动平衡，避免振动、污染和噪声，它在超高速切削机床上得到了广泛的应用。美国、德国、日本、瑞士、意大利等工业发达国家，都在高速数控机床上广泛采用了电主轴结构。

Spindle Technology and Development Trend
NC machine tools are the combination of high-efficience,high-precision and high-flexbility.At the same time,for the purpose of getting high-productivity and improving the cutting accuracy,the technology of high-speed cutting is getting more and more attention in the professional fields.
   The super-high-speed NC machine tools are the material foundation for achieving super-high-speed cutting,and electronic spindle is the key component that makes the machine tools high-speed.Its performance directly influences the NC machine tools’performances on the super-high-speed cutting.The key component not only requires a high accuracy of speed,but also requires to have the ability of constantly outputting high torque and a wide range of constant power operation.Therefore,the electronic spindle of the NC machine tools is produced which has the corresponding characteristics of high-speed,high-precision,high-proficiency and high-efficiency.
