Mechanical feeders and NC servo feeders are two commonly used roll material feeding devices in automated processing. Customers typically choose between these two models when selecting a feeding machine. This article aims to explain the similarities and differences between the two types of machines to help customers make an informed decision.

1.The range of applications for the two punching press feeders is significantly different:

    • Mechanical feeders are only suitable for use with various types of punching presses with output shafts, and there are strict limitations on the feeding width and feeding pitch. Usually, mechanical feeders cannot be selected if the material width exceeds 500mm or the feeding pitch is greater than 300mm. However, mechanical feeders also have advantages. Their high-speed models can achieve a large feeding speed of up to 500 times/min and can be used with high-speed punching presses.
    • NC servo feeders are suitable for use with various types of punching presses, hydraulic presses, shearing machines, laser cutting machines, and other types of processing equipment. There are no limitations on the feeding width and feeding pitch, and they have a high degree of customization. They have a wider range of applications than mechanical feeders. However, due to the response time of the servo motor, NC servo feeders are not suitable for high-speed feeding applications.

2.There are significant differences in the use and debugging of the two punching press feeders:

    • Mechanical feeders feeders are mechanically driven, and the feeding time and feeding pitch need to be adjusted by fixing an eccentric disc on the output shaft of the punching press. Debugging is relatively cumbersome, and requires a high level of professionalism.
    • NC servo feeders come with a standard 7-inch touch screen. The feeding pitch, feeding frequency, and other adjustments can be easily set on the touch screen, making it easy for anyone to use.

3.There are significant price differences between the two punching press feeders:

    • Mechanical feeders do not have motors or electrical components, so they are relatively inexpensive.
    • NC servo feeders use a complete set of Yaskawa servo control systems. The price of a single servo motor alone far exceeds that of a mechanical feeder, making it much more expensive.

In summary, the main differences between mechanical feeders and NC servo feeders lie in these three aspects. Processing and production companies can choose according to their own needs. Mechanical feeders are economically affordable, but their operation is relatively cumbersome, their range of applications is smaller, and their personnel requirements are higher. NC servo feeders have a higher initial investment cost, but are easier to operate, have a wider range of applications, and are more suitable for the long-term development needs of the enterprise.
