Machine to unload position - Roll stop - Faceplate retracted - Tailstock quill retracted ;Soft loader up Program end Ready to unload the roll;Machining Example: Steel Industry (Hot Mill);上面的动画和图示告诉我们磨床的工艺过程,那么它是通过什么手段来实现工艺要求?这需要我们了解磨床内部的机械液压部分和电气自动化控制部分.;我们先看磨床的机械结构:是直接看机械图?还是看模型和照片?;CP-Type;相比较其他数控机床,轧辊磨床的液压部分要复杂许多.主要是因为: 1.它加工的工件重; 2.工作过程中负荷大. 这两个原因直接带来的问题就是: 1.工件的安装定位难; 2.运动部件的摩擦和磨损大. 而液压技术可以很好的解决这两个问题.;首先解决安装定位的问题.;在解决摩擦和磨损问题;磨??的电气控制部分;西门子公司;倍福公司;磨床的操作和工艺;备件工作;面对问题,思路何在?;标准和规程;大家觉得还需要一起学习点什么?
