In today’s manufacturing landscape, where efficiency and precision are paramount, the coordination between workstations in stamping and feeding processes holds critical importance. However, challenges arise when the material strip undergoes irregular stretching or fails to feed properly, resulting in subpar stamping outcomes and a surge in defective products. These issues often stem from factors such as excessive elasticity in the material, inadequate discharge load, or the thinness of the material strip.

Addressing Challenges with NC Servo Feeders

To combat these challenges effectively, the integration of two NC servo feeders with a stamping press proves to be a game-changer. By adopting a one-feed-one-pull feeding mode, this setup ensures rapid and precise material feeding, thereby guaranteeing stability and high precision in the stamping process.

How Two NC Servo Feeders Work in Tandem

The configuration involves two NC servo feeders, each driven by a dedicated set of servo systems. These systems can be strategically positioned either on the left and right sides or the front and rear of the setup. The sheet metal is fed through specialized feeding rollers, with the pressure distributed evenly across individual rollers, whether for feeding or pulling the material. To maintain consistent feeding and pulling, both NC feeders utilize a mechanism for automatically releasing accumulated errors and internal stresses by elevating the cylinders. This approach effectively minimizes the impact of material deformation on the processing area.

Seamless Operation of One-Feed-One-Pull NC Servo Feeder

In operation, the one-feed-one-pull NC servo feeder system functions seamlessly. Initially, the servo motor of the feeding servo feeder propels the front rollers forward for material feeding. Simultaneously, the servo motor of the pulling servo feeder drives the rear servo feeding rollers forward in synchronization with the feeding process. As the sheet metal advances to the front rollers, both sets of rollers work in unison to facilitate continuous feeding. Once the material reaches the desired length, the cylinder undergoes a temporary lift before descending again. This cyclical process repeats, ensuring precise feeding and relaxation, thereby addressing issues related to irregular stretching or improper material feeding. Consequently, this setup guarantees stable stamping accuracy and maintains the high quality of processed products.


Incorporating a one-feed-one-pull NC servo feeder system into stamping processes revolutionizes manufacturing efficiency and precision. By overcoming challenges associated with material irregularities and feeding inconsistencies, this setup elevates the overall quality of stamped products while optimizing production outcomes. Embracing innovative solutions like NC servo feeders underscores a commitment to excellence in modern manufacturing practices.
