finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 gears to reduce the slab's thickness by as much as 2-½".

Ball Mill Specifications All-Steel Shells and Heads. Ball-Rod Mills have heavy rolled steel plate shells which are arc welded inside and outside to the steel heads or to rolled steel flanges, depending upon the type of mill. The double …
Although it appears simple enough, there are many considerations that come into play in precision metal cutting and machining. In this first part of a series, we cover the names of the components and processes used in precision machining. These include setup factors like spindle speed and cutting speed, material hardness and ductility, and the physical setting and rigidity …
