What will cause the inaccurate feeding of the servo feeder? How to solve?

Inaccuracy feeding occasionally happens in the metal coil feeding process. Various reasons caused the feeding accuracy problem, HE-machine summarized the leading causes and solutions for the inaccurate feed of NC servo feeder.

The sheet metal coil will always be biased in one direction because of the uneven feed roller pressure, which will cause inaccurate feeding.

What Can Do: If the coil sheet always biased to the left, it means the pressure on the left is too large. At this time, turn the left pressure adjustment nut counterclockwise to reduce the left spring pressure until the material runs back to the correct position, or turn the right pressure adjustment nut clockwise to increase the right side spring pressure.

The soft material is easy to deform will also cause inaccurate feeding, such as copper, aluminum. Excessive pressure on the upper roller may cause elastic material deformation and bias. The coil sheet will sometimes go to the left side and sometimes go to the right side.

What Can Do: Please unplug the lower tube of the release air cylinder and fold it up. If the material is still deformed, please rotate the two pressure adjustment nuts counterclockwise to release the pressure. We must know your coil material kind before produce a servo feeder machine. Please confirm your coil feeding material with our sales before purchasing.

The thickness of the two sides of the material is different, or the article has grinding burrs, which will cause the article always to be biased to one side when feeding.

What Can Do: Adjust the pressure adjustment nut and change the inlet locating wheels to the inlet locating plates. Otherwise, we can only try to replace the materials.

Wrong machine processing or assembly will also cause inaccurate feeding. This problem doesn’t happen in HE-machine servo feeders yet. But if any fault of our servo feeder, please contact us soon to solve the problem in time.
