Figure 2.4 shows the appearance of the integrated CNC machine tool.

Figure 2.5 shows the appearance of the tool magazine and the machine tool as a separate CNC machine tool.

At this time, the capacity of the tool magazine is large, the tool can be heavy, and the transportation device is often attached to complete the transportation of the tool between the tool magazine and the spindle.
Dongguan CNC processing plant The tool changer with tool magazine is composed of tool magazine, tool selection mechanism, automatic tool loading and unloading machine and tool exchange mechanism (manipulator), which is widely used. The automatic tool change system of tool magazine manipulator, the whole tool change process is more complex. First of all, all the tools used in the machining process should be installed on the standard toolholder. After the size is pre adjusted outside the machine, they should be put into the tool magazine in a certain way. When changing the tool, first select the tool in the tool magazine, then take the tool from the tool magazine or the spindle by the tool changing device, and exchange the new tool into the spindle, and put the old tool back into the tool magazine.
Dongguan CNC processing plant Because the first two kinds of tool changing devices can not hold too many tools, which can not meet the needs of complex parts processing, so the automatic tool changing CNC machine tools mostly use the automatic tool changing device with tool magazine. The tool magazine has a large capacity, which can be installed on the side or above of the spindle box. Because there is only one spindle in the spindle box of CNC machine tool with automatic tool changing device of tool magazine in Dongguan CNC processing plant, the stiffness of spindle components should be high to meet the requirements of precision machining. The number of tool magazine is large, so it can meet the multi process processing of complex parts and greatly improve productivity. The automatic tool changing system with tool magazine is suitable for NC drilling center and machining center. It is concluded that the automatic tool changing system with tool magazine is the most promising.
