Navigating the world of NC servo feeders can be daunting, especially with the two prominent variants: the popular pneumatic NC servo feeder and its mechanical counterpart. Each serves its unique purpose in the industry, yet their applications and characteristics are far from identical. So, how do these models stack up against each other? And how can we optimize their use in various operations? Let’s delve into a closer examination of these innovative machines.

A Comparative Look at Pneumatic and Mechanical NC Servo Feeders

In the realm of NC servo feeders, the pneumatically driven variant holds the banner of the standard model. Its prestigious title, however, is less about unmatched performance and more about versatility. Harnessing the power of an electromagnetic valve release mechanism, this model shines in its adaptability, being user-friendly and flexible to a variety of machine applications. From punch presses to shearing machines, and hydraulic presses, its applicability is undeniably vast.

On the other side of the spectrum, the mechanically driven NC servo feeder offers a more specialized approach. As an optional model, it touts a mechanical rod release mechanism, necessitating the need for a separate release bracket apparatus. This requirement makes it specifically tailored for punch press applications. Yet, despite its niche focus, this model’s prowess in high-speed feeding and synergy with traditional punch presses outstrips the pneumatic variant’s performance.

Distinguishing Features: Mechanical vs. Pneumatic NC Servo Feeders

While the release methods set these two NC servo feeders apart, they also bear unique traits. The mechanical NC servo feeder notably includes a material thickness adjustment disc and a release handle. These components necessitate adjustments according to the material thickness during operation. In contrast, the pneumatic version uses cylinder pressure on the material, thereby eliminating the need for such tinkering.

Many stamping business owners familiar with pneumatic NC servo feeders often grapple with the task of adjusting material thickness with the mechanical model. To provide clarity, we’ve detailed the adjustment process for the mechanical NC servo feeder in the next section.

Mastering Material Thickness Adjustments in Mechanical NC Servo Feeders

  1. Start by lifting the release handle to distance the upper roller from the lower one.
  2. Then, slide the sheet material from the material rack through the upper and lower rollers, and into the punch press. Lower the release handle to secure the material strip between the rollers.
  3. Proceed to loosen the material thickness adjustment disc’s set screw. Adjust the disc handle upward or downward to match the actual material thickness. Make sure the adjusted release bracket has a lateral clearance of 5mm (Note: Overly large or small bracket clearances can lead to inaccurate feeding).
  4. Once done, tighten the set screw of the material thickness adjustment disc, and you’re ready to commence with the actual stamping feeding production.


Remember, when operating the mechanical NC servo feeder, any change in material thickness requires a subsequent readjustment of the material thickness adjustment disc. This ensures the precision of feeding. As you continue to work with these feeders, this in-depth understanding of the pneumatic and mechanical models will undoubtedly optimize your operation, delivering enhanced productivity and efficiency.
