Frequently Asked Questions
A V-opening refers to the width of the die opening in a press brake used for bending sheet metal. The size of the V-opening affects the bend radius and the quality of the bend.
The right V-opening depends on your sheet thickness and material. Our calculator provides recommended minimum, optimal, and maximum V-opening sizes based on industry standards.
Using too small a V-opening can damage your tooling or cause cracking in the material. Too large a V-opening may result in inaccurate bends or excessive springback.
