Main Features:

• Front supports: 2 pieces on linear guides, ensuring stability during bending operations

• Y1, Y2 axis adjustment: automatic

• Back gauge adjustment (X axis): servo drive on encoders

• R axis adjustment: servo drive on encoders

• Automatic deflection arrow adjustment

• Mounting double-sided punch: AMADA quick assembly, enabling quick tool changes

Technical parameters

Automatic adjustment of bumper departure (X axis) and R axis (manual option). R axis for easy bending of larger radii, e.g. with a stepper system.

Optional finger adjustment in axes Z1,Z2,R1,R2,X1,X2 on servomotors.

In order for the effect of the performed step bending to be satisfactory, it is necessary to perform certain calculations, which, however, require knowledge of several of the most important parameters related to the bending process - these are:

• Arc length - the distance between the ends of the curve of the bent part of the sheet metal counted on the inside of the bend;
• Number of bends - the number of individual bends that must be performed to obtain a bent sheet metal with a specified radius; the greater the number of bends, the smaller the angle of a single bend and, as a result, the smoother the arc;
• Distance between bends – the distance between individual bends made during the process.

Although the entire step bending process may seem quite complicated, the machines and software available at CORMAK are already at such an advanced stage that in many matters they completely replace the operator.

Automatic compensation of the deflection arrow

Ensures the same bending angle along the entire bending length - (option)

Manual deflection arrow compensation (option)

Ensures the same bending angle along the entire bending length - (option)
