In the tool exchange of CNC machining center, in addition to the tool holder, the tool magazine can also be used to realize the tool change process. The main power of the tool magazine comes from the electric motor and hydraulic system to provide transmission power, and the positioning unit is used to ensure that each tool and tool sleeve that is replaced can rely on accurate stop. The CNC machining center is fully enclosed and protected, and the working procedures are concentrated and the machining process is continuous. The use of multiple tools can easily realize the automatic tool change process, and the use of multiple workbenches can automatically perform workbench exchange. At the same time, the CNC machining center also has a very powerful function support, and it is more inclined to compound processing. High degree of automation, high precision and high sales volume. Under appropriate circumstances, it can be brought into full play. According to the specific structure, it can be divided into three forms: vertical, horizontal, and gantry. The difference between CNC machining centers and other CNC machine tools is that CNC machining centers have tool magazines and automatic tool change devices, while other CNC machine tools do not have tool magazines and automatic tool change devices. This is the difference between CNC machining centers and other CNC machine tools. This is also processing. The advantage of the center lies. With automatic tool changer and tool magazine, the workpiece can be clamped at once without manual labor, and multiple procedures can be completed automatically. Do you know which CNC machining center tool magazines that require operators? As we all know, the tool magazine of CNC machining center can be divided into two types according to the tool change: the tool magazine of the operator is required, and the tool magazine of the operator is not required. There are two types of tool magazines of the CNC machining center: the disc tool magazine and the chain tool magazine. , Both of these two CNC machining centers use robotic arms to complete the tool change process, so the difference between these two tool magazines lies in this.
