1. The power and stiffness of the punch feeder and the range of maneuver should be compatible with the nature of the process and the most appropriate amount of cutting. If the blank amount removed by the roughing process is large and the cutting allowance is selected large, the machine tool is required to have large power and good rigidity.
2. The structure of the punch feeder depends on the size of the machine tool and the weight of the workpiece.
3. The working accuracy of the punch feeder is compatible with the machining accuracy required by the process. According to the machining accuracy requirements of the parts, the machine tool should be selected. For rough machining processes with low precision requirements, machine tools with low precision should be selected. For precision machining operations with high precision requirements, high precision machine tools should be used.
4. The size of the main specifications of the punch feeder should be adapted to the contour size of the workpiece. That is, small workpieces should be machined with small specifications, while large workpieces should be machined with large specifications to ensure fair use of the equipment.
5. The convenience of the clamping and the simple structure of the fixture are also factors that need to be considered in selecting the punching machine. The choice of horizontal punch feeder is still the choice of vertical punch feeder, which will directly affect the structure and machining coordinate system of the selected fixture, which is directly related to the difficulty of CNC programming and the reliability of CNC machining.
It should be noted that in the selection of the punch feeder, the function of the numerical control equipment should be fully utilized, and the development should be carried out as needed to expand the functions of the punching machine and meet the needs of the product. Then, according to the selected punch feeder, the numerical control processing scheme and the process route are further optimized, and the contents of the process are appropriately adjusted as needed.
