What many people overlook: Even the smallest cracks at the edges of steel strip can lead to material failure under stress – with serious consequences for components such as springs, band saws, and many other applications.

Why Do These Microcracks Occur?
Microcracks often develop under continuous load on strip materials. During the cutting of metal strips, a fracture edge is created, making tiny edge cracks almost unavoidable. These cracks can grow under stress and significantly increase the risk of material failure.

How Can This Be Prevented?
By deburring the strip edges and removing the fracture edge, the risk can be significantly reduced. However, in many deburring systems, the burr is broken off across the strip direction. This process creates fine grooves that can actually promote crack formation.

The Solution: Precision Edge Rounding by Grinding
With precision edge rounding by grinding, the process runs lengthwise along the strip direction. The result: grooves aligned with the direction of tension – no transverse notches. Bend tests clearly show: material that has undergone precision edge rounding lasts longer and breaks later than conventionally deburred material.

A key insight for anyone focused on durability and quality:
Precision edge-rounded material can significantly extend the service life of your components.
