通过本刊以前几讲的介绍,读者对组合机床的总体设计、液压系统的设计都有了一定的了解。我们知道,组合机床是针对某些特定工件,进行特定工序加工而设计的专用设备。这样,对于为不同的被加工零件、不同的加工工序而设计的组合机床,其电气控制系统也各不相同。目前一般接触到的组合机床,当其对工件的加工工艺范围确定以后,则其主轴转速、动力头进给速度及整个机床的工作循环就都确定下来了,这就使得组合机床的电气控制系统可
Through the introduction of several previous articles, the reader of the overall design of the combination of machine tools, hydraulic system design have a certain understanding. We know that the combination of machine tools for certain specific parts, for the specific process of processing and design of special equipment. In this way, for different parts to be processed, different processing processes designed machine combination, the electrical control system is also different. The current general access to the combination of machine tools, when the processing of the workpiece to determine the scope of the process, the spindle speed, power head feed rate and the entire work cycle of the machine are determined, which makes the combination of machine electrical control system can
