BLISS-BRET straightening and straightening presses

Editing and straightening are operations for straightening metal, blanks and parts that have dents, bulges, waviness, warping, curvature, etc. Editing and straightening have the same purpose, but differ in the methods of execution and the tools and devices used.

Sheet material and blanks from it can be warped at the edges and in the middle, have bends and local irregularities in the form of dents and bulges of various shapes. When considering the deformed workpieces, it can be seen that their concave side is shorter than the convex one. The fibers on the convex side are stretched, while those on the concave side are compressed.

The metal is straightened both cold and hot. The choice of method depends on the amount of deflection, dimensions and material of the product.
