With the right equipment and proper setup, tube mills can produce dimple-free round tubing efficiently. A multistep process using a two shear blade makes a dimple-free cut, and an inline brush end finisher can be used to remove the ever-present clearance burrs, if needed

When properly selected and utilized, single-cut die sets can produce top-quality cut ends on square and rectangular tubing. This article discusses the criteria for selecting and using the die sets to achieve the best results.

This article covers the application of single-cut and dimple-free cutoff shear technologies as they are applied to contemporary high-speed tube mills.
