1. The working accuracy of the automatic 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 processes with high precision requirements, high precision machine tools should be selected.

2. The size of the main specifications of the automatic feeder should be compatible with 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 achieve reasonable use of the equipment.

3. The power and stiffness of the automatic feeder and the maneuver range should be compatible with the nature of the process and the most appropriate cutting amount. For example, a feeder with a large power and a good rigidity is suitable for a large margin of the blank removed by the roughing process.

4, the structure of the automatic feeder depends on the size of the machine tool, the weight of the workpiece and other factors, so be sure to understand the needs before you choose, select as needed.

5, convenient clamping, simple structure of the fixture is also a factor to consider when choosing punching equipment. Whether to choose horizontal automatic feeder or vertical automatic feeder will directly affect the structure and machining coordinate system of the selected fixture, which is directly related to the difficulty of NC programming and the reliability of CNC machining.
