The distance between scallops is referred to as pitch. Haas roughing end mills come in fine- and coarse-pitch versions. Fine-pitch scallops are smaller and better for lighter cuts in hard materials. The fine-pitch end mills leave a better finish, and don't require as much stock to be left to clean up with a finish pass using standard end mill.

4-High Rolling Mills. Four-high rolling mills can be put in tandem, two to seven stands, instead of a reversing mill. They can be equipped with load cells to tell the separating force and hydraulic or mechanical screw downs, depending if it is hot or cold rolling. Sometimes mechanical screw downs are preferred when there is a risk of fire.

CONCLUSIONS In heavy-plate rolling, there are many roughing mills where the roll gap height cannot be adjusted during the rolling pass. For such roughing mills, the possibility of using edger rolls to improve the lateral motion of the plate and to reduce its camber was examined. The mathematical model of Ettl et al. (2018) was extended by ...
