The small machining center is a highly automated cnc machining equipment, which can complete many processing contents such as milling, drilling, boring, reaming, tapping, etc. at a time when the workpiece only needs to go through the clamping process once. Before the workpiece is processed, it must first be processed in terms of technology, including the treatment of tool setting and tool change, the choice of clamping method and the selection of tool.
1. Treatment of tool setting and tool changing
Complete machining of a workpiece by a small machining center requires the participation of several or even dozens of tools. In order to establish the corresponding relationship between the parameters of each tool type and the processing of each process of the workpiece, and the position of the tool change. The tool setting operation must be carried out, otherwise serious consequences will occur.
2. Selection of clamping method
We know that the most significant feature of cnc machining parts in small machining centers is the centralized processing of the process, and the workpiece must be re-set for each clamping, which will greatly increase the time of auxiliary processing and affect its processing efficiency, so I choose the clamping method It is possible to process most of the surface to be processed after one clamping as much as possible.
3. Tool selection
Small machining center workpieces need to be loaded into the tool magazine before machining the workpiece. The selection of the tool should be based on the cutting performance of the material of the part; the selection according to the processing stage of the part and the characteristics of the processing area.
