Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.
A reversing mill is a rolling mill in which the workpiece is passed forward and backward through a pair of rolls. The reversing mill is so named because the steel runs back and forth between the rollers, reducing the thickness incrementally with each pass. A reversing mill can be used to reduce material to gauge.
Roughing and finishing end mills are made from a variety of materials that are chosen according to the degree of precision, hardness, durability and wear resistance required by your application. Cobalt (321) Cobalt is harder than high speed steel and provides better wear resistance. It .

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 .
Feb 01, 2016· For high-speed roughing, width of cut is usually set at somewhere between 5 and 10 percent of the cutting tool diameter. This means a 0.50-inch end mill will be engaged 0.025 to 0.050 inch. This setting will impact RCT calculations as well. For example, the average recommended feed rate for a 0.50-inch tool is approximately 0.002 inch per tooth.
Roughing end mills, also known as hog mills, are used to quickly remove large amounts of material during heavier operations. The tooth design allows for little to no vibration, but leaves a rougher finish.
Regal Cutting Tools manufactures a variety of roughers for a wide range of materials and conditions. Heavy cuts can be achieved because our roughing end mills have a much higher effective feed per tooth than a conventional end mill.
