Press Brake

NC Press Brake

If you have limit budget, the NC press brake will be a good choice for you to finish sheet metal bending.

Press Brake

CNC Press Brake

CNC press brake has much higher accuracy, efficiency than NC press brake when bending metal plate.

Robotic Press Brake

Robotic Press Brake

Robotic press brake It can efficiently and accurately complete the automatic bending of sheet metal.

How is the bending coefficient of sheet metal calculated

The calculation formula is as follows:

L=0.5π ×( R + K coefficient × T) ×(θ/ 90)

L: Unfold length of sheet metal
R: Inner radius of bend
T: Material thickness
θ: Bending angle
Y factor: a constant determined by the position of the neural bend line. Its default value is 0.5 (the so-called “bend line”).

In the practice of sheet metal design, the commonly used sheet metal flattening calculation formula is based on the K coefficient, which ranges from 0 to 1, indicating the resistance of the material to stretching during bending.

The relationship with the y coefficient is as follows:
Y coefficient = (π / 2) × K coefficient
