After the precision parts are processed once and clamped, the digital control system can control the machine tool to automatically select and change the tools according to different procedures, and automatically change the spindle speed, feed, and the absolute workpiece trajectory of the tool and other auxiliary functions, which are completed in sequence. Multi-process processing on several surfaces of the workpiece. And there are a variety of tool change or tool selection functions, which greatly improves the efficiency of consumption.
Due to the concentration of processes and automatic tool change, the precision parts machining center has increased the work of workpiece clamping, measurement and machine tool adjustment, so that the cutting time of the machine tool reaches about 80% of the machine tool start time (normal machine tool is only 15-20%) ; At the same time, it also increases the work-piece turnover, handling and storage time between processes, prolongs the consumption cycle, and has a clear economic effect. The precision parts machining center is suitable for small and medium-sized batches of relatively complex parts, high precision requirements, and frequent product changes.
