HYDRAULIC ROLLING MILL - Tools and Tool Making ...

May 02, 2015  That is a sexy rolling mill. You're going to love the press/rolling mill combo if you haven't worked with one before. I love mine. It draws billets out way faster than my 24 ton hydraulic press. I set the weld on the press, make passes on the press until it's about 1/2" thick, then draw on the mill. Works really fast. Beautiful machine work. --Dave
