Milling (machining)Wikipedia

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.

RubberProcessing Britannica

Rubber mills have two large horizontally opposed, closely spaced steel cylinders, up to 3 metres (10 feet) long, that are rotated slowly in opposite directions and at somewhat different speeds. Rubber is sheared and softened in the gap between the paddles and wall of the Banbury mixer and in the gap between the two cylinders in the roll mill.

Oct 12, 2012 · Visser I've found that many new operators don't know the differences between materials, be they aluminum, steel, stainless steel, or anything else. One grade of metal will roll far differently from another. For instance, aluminums can vary in strength from T0 to T6. The aluminum 50 series can be a T0 (very soft) while a 60 series can be at least a T3, and sometimes even a T6.

Rolling (metalworking)Wikipedia

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
