Introduction to the function and working principle of vertical CNC machine tools

With the industrialization of industrial production activities, people increasingly demand the interchangeability of workpieces. In order to ensure better interchangeability of workpieces, it is necessary to require workpieces with good machining accuracy, so that CNC machine tools become important equipment to ensure machining accuracy and machining price. CNC machine tools are highly automated and can avoid errors caused by manual manipulation. Since more complex workpieces may require relatively more processing steps, if each step is stopped to change the tool, and the tool is re-calibrated and the workpiece is aligned, it will definitely increase the production cycle and reduce productivity. The processing time of a CNC lathe is mainly composed of several processes of working, aligning, turning, and unloading. Repeating the two processes of working and aligning will cause a lot of waste of time, increase cnc machining costs, and reduce productivity. In order to solve this problem, it is necessary to add a tool magazine to the CNC machine tool so that it can automatically change the tools of different processes without stopping the machine.

1 The role of vertical lathe tool magazine

Since the tool compensation is set for the tip of each tool in advance, there is no need to re-calibrate the tool after changing the tool. It can realize the continuous processing of multiple procedures in the process of one card installation. It can greatly improve production efficiency, minimize the uncertain factors of manual operation, and improve the yield of workpieces. For the tool magazine system of a CNC vertical lathe, replacing the tool holder with a turning tool in advance is a relatively simple tool change method.

The turning tool is pre-installed on the tool holder, and then the tool holder is placed on the radial position of the tool holder frame in turn. When the tool needs to be changed, the CNC system sends a command to drive the servo motor and drive the large ring gear through the anti-backlash gear Rotate the corresponding angle to rotate the corresponding tool to the tool change position. At this time, the vertical tool post enters the tool change position, remove the tool holder, and return to the cnc machining parts position to continue processing the next process.
