10 Tips to Improve Surface Finish
For example, when you’re using a 45-degree lead face mill, the cutting force will act downward at 45 degrees, perhaps causing the part to flex after the cutter has passed over the part. This in turn causes the back half of the cutter to recut the machined part, resulting in a negative impact on surface finish.

What is a Mill Coating?
When plates, sheets and other materials made of steel are produced, they produce a mill scale consisting of iron oxides that layer on the top surface, protecting the underlying steel from corrosion. Coatings cannot be applied over this mill coating, so the mill coating must be removed before further protective processes are performed.

Milling surface generation
To generate the best milling surface finish, it is important to ensure that the feed per revolution (f n = f z x z n) is less than 80% of BS.As cutter diameter increases (and for extra close pitch cutters), the number of teeth as well as feed per revolution increases, requiring a larger BS.

Stainless Steel Finishes Explained
2F Finish. It usually starts with a 2B or 2R mill finish. So, the common processing involves cold rolling, heat treatment, and skin pass on roughened rolls. Sometimes, bright annealing or annealing and pickling can be performed. The result is a low-reflective stainless steel finish. It is a uniform matt surface on both sides of the sheet.
