The NC servo feeder is an exceptional feeding machine that offers versatility beyond its use with punch presses. It seamlessly integrates with various processing machines, including shearing machines, hydraulic presses, forming machines, and laser cutting machines. However, it’s crucial to note that there are distinct differences in the control methods when utilizing the NC servo feeder with punch presses versus other types of processing machines. This article explores these differences and highlights the benefits of leveraging the shearing function of the NC servo feeder for enhanced automated punching production.

Control Methods for Punch Presses

When employed in conjunction with a punch press, the operation of the NC servo feeder primarily relies on the punch press cam signal. This signal controls the precise feeding actions of the NC servo feeder, ensuring optimal coordination with the punch press. This integration enables efficient and synchronized operations, resulting in high-quality output.

Control Methods for Other Processing Machines

Conversely, when the NC servo feeder is utilized with other equipment such as shearing machines, hydraulic presses, forming machines, or laser cutting machines, it adopts a different control approach. In this scenario, the NC servo feeder predominantly generates a shearing signal to govern the operation of the associated processing equipment. This shearing signal acts as a command, ensuring seamless coordination and precision during the material processing.

Leveraging the Shearing Signal for Punch Press Feeding

In certain cases, the NC servo feeder can also be externally controlled by a shearing signal, specifically for punch press feeding in long-stroke material handling operations. By incorporating this functionality, the NC servo feeder expands its capabilities, enabling efficient handling of extended feeding processes.

Challenges in Long-Stroke Punch Press Material Handling

When the NC servo feeder is employed for long-stroke punch press material handling, the feeding time naturally becomes longer. However, utilizing a standardized punch press control method for continuous punching and feeding may present challenges. Specifically, there is a risk of the punch press slide reaching the bottom dead center position before the NC servo feeder completes the feeding process. This misalignment hampers accurate feeding operations, potentially leading to production inefficiencies.

Overcoming Challenges with Shearing Control

To address the aforementioned challenges, a more effective and reliable solution involves utilizing the shearing function of the NC servo feeder to control the punch press operation. This approach enables long-stroke continuous automated punching production while maintaining accuracy and efficiency.

Implementing Shearing Control

In practical use, implementing shearing control involves establishing an additional shearing control line. This line connects the electrical control box of the NC servo feeder to the footswitch of the punch press. By doing so, the NC servo feeder emits a shearing signal that governs the punch press for automatic punching operations. This process occurs once the punch press switches to footswitch mode after initiating the NC servo feeder’s automatic feeding.

Benefits of Shearing Control

By leveraging shearing control, stable and automated punching production for long-stroke applications can be achieved. This approach eliminates the need for manual intervention, allowing for uninterrupted continuous punching operations. The seamless integration of the NC servo feeder and the punch press enhances productivity, reduces downtime, and improves the overall efficiency of the manufacturing process.


The NC servo feeder stands as a versatile feeding machine, facilitating not only punch press operations but also various other processing machines. Understanding the distinctions in control methods is essential to maximize the benefits of this remarkable equipment.
