This video will tell you how to correct the bending angles on the NC Press brake, when you test the bending angles on each side of the machine, if the results are different, you can follow the video tutorial to learn how to fix the problem.

I can guide you through the general process of adjusting the bending angle of an NC press brake by adjusting the synchronizing rod. Here are the steps you can follow:

● Understand the Synchronizing Rod: The synchronizing rod is a critical component of a press brake that ensures both sides of the cylinder move together, maintaining parallelism during the bending process.

● Safety First: Before making any adjustments, ensure that the press brake is turned off and disconnected from its power source. Also, wear appropriate safety gear such as gloves and safety glasses.

● Measure the Bending Angle: Put two small plates underneath the cylinders on both sides and bend them twice under the same Programma, measuring the bending angle respectively. Animation can be seen, the left side of the bending angle than the right side of the bending angle of 2 degrees larger. This will serve as your baseline for adjustments.

● Access the Synchronizing Rod: Depending on the design of your press brake, you may need to access the synchronizing rod from different points.

● Adjustment Procedure:

Loosen the 3 bolts on the smaller angle side of the synchronizing rod. This will allow you to make adjustments to it.

Turning the synchronizing lever counterclockwise increases the bending depth therefore the bending angle decreases. Normally, the amount of movement is 0.1mm for one turn counterclockwise, depending on the thickness of the sheet to be bent and the size of the groove. If the groove is V16, and bending 1.8mm sheet, the angle controlled by rotating the synchronizing lever one turn is about 1 degree. And after adjusting, we need to tighten the 3 belts on the rod.

At this time, we will synchronize the rod's counterclockwise rotation of two turns, at this time the bending depth deepened, the bending angle is reduced.


● Test the Adjustment: After making adjustments to the synchronizing rod, perform a test bend using a piece of scrap material. Measure the bending angle again to ensure it meets your requirements.

● Fine-tune if Necessary: If the bending angle is still not correct, make further adjustments to the synchronizing rod until the desired angle is achieved.

● Secure the Adjustments: Once you're satisfied with the bending angle, tighten the bolts or secure the hydraulic cylinders to prevent the synchronizing rod from moving during operation.

● Final Inspection: Before resuming normal operation, double-check all adjustments and ensure that the press brake is functioning properly.

● Regular Maintenance: Periodically check and adjust the synchronizing rod as needed to maintain accurate bending angles over time.
