NC locomotive technology is the most widespread application. Numerical control there is in the future lathe to in will develop, the middle-grade to adopt popular numerical control knife rest form a complete set, adopt the motive force type knife rest top-grandly, have such varieties as knife rest of hydraulic pressure, servo knife rest, vertical knife rest, etc. concurrently, it is estimated that will increase to numerical control knife rest demand greatly in recent years. The development trend of the Numerical control rotary table is: With the development of numerical control lathe, numerical control knife rest begin to change one hundred sheets , electric liquid is it urge and urge direction develop while being servo to make up fast. Some originally design and is it continue electricity to use to four worker location vertical electronic machinery of knife rest mainly- exposed to control system control some designs. And use AUTOCAD to pursue to the above part, have a more ocular knowledge of electronic knife rest. The last proposition has put forward the suggestion and measure to Numerical control rotary table. Key words：umerical control rotary table； ear drive；orm drive；ap elimination； worm gear step up 目 录 第1章 绪 论 1 1.1 数控技发展简史 1 1.2 机床数控化改造的必要性 3 1.3 机床数控化改造的内容及优缺点 4 1.4 数控系统的选择 4 1.5 数控改造中主要机械部件改装的探讨 5 1.6 数控技术发展趋势 6 第2章 数控回转工作台的原理与应用 9 2.1 数控回转工作台 9 2.2 设计准则 10 2.3 主要技术参数 10 2.4 本章小结
