Mill finish aluminum sheet metal is made with regular aluminum not painted, instead, a brushed finish similar to a #4 finish on stainless steel.. Used for gutters, metal roofing panels, downspouts, chimney caps, cupolas, louvers, finials, edge metal, flashing, step flashing, leader heads, gutter accessories, conductor boxes and skylights.
Mill finish is the surface texture (or finish) of metal after it exits a rolling mill, extrusion die, or drawing processes, including sheet, bar, plate, or structural texture is usually rough and lacks lustre; it may have spots of oxidation or contamination with mill oil. Most mill finish surfaces are machined or treated with polishing, industrial etching, or some other surface

Mill Finish is a basic finish of aluminium extrusion products, it has not gone through further mechanical or chemical process. Aluminium in general has high resistance to corrosion, because it is spontaneously covered by a thin layer due to the result of oxidation that makes product more durable.
#0183;#32;A textile mill is a manufacturing facility that is involved in some aspect of textile manufacturing. Many people use the term to refer specifically to a plant where textiles are made, although it may also refer to facilities that process textiles and turn them into finished products, such as clothing.
Mill finish is the natural finish that aluminum extrusions have as they emerge from the extruder die. It''s basically bare aluminum. Mill finish will oxidize with a light white powder (aluminum oxide) as it is exposed to air and moisture. It can oxidize a lot under very moist or salty conditions.
Many of DeepRoots products are defined by their mil thickness. Our Geomembranes (Water Barrier and Bamboo Barrier), for example, have varying thicknesses of 30, 40 and 60 mil, while our root barriers are all 80 mil what is a mil? A mil is a thouh of an inch .001 inch. It is a typical manufacturing dimension.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
#0183;#32;Roughing end mills quickly remove large amounts of material. This kind of end mill utilizes a wavy tooth form cut on the periphery. These wavy teeth form many successive cutting edges producing many small chips, resulting in a relatively rough surface finish.
#0183;#32;A mill finish is typically the finish a material has as it exits the mill where it is processed. Most metals, such as aluminum, are polished after they leave the mill. This leaves the materials bright and shiny and removes any residue that might be present. A mill finish, however, will often be dull, grainy and without a certain luster.
If your mill is well trammed, youll see equal tooling marks on both sides. If the spindle leans into the cut a bit, youll only see one tooling mark. Some folks prefer the symmetry of two marks and some prefer the one. Either way, if finish matters and your mill is trammable, youll want to retram just before critical finish

Mill Finish is a very lightly oxidized film and will wipe off with your bare finger and immediately form. Rolled sheet would probably have a thinner oxide than hot extruded aluminum. If you want to bond silicone adhesive then you want a phosphate etch, or a light chromate or a thin (.0004 anodize in either chromic, sulfuric, or phosphoric.)

The third image uses a smaller end mill to finish up more of the finer details, but it would take about 3 hours you can see this tradeoff between getting more details for the price of longer mill times (would wear out your end mill faster). In the first picture I have a 3/32quot; end mill.
Face milling A face mill machines a flat surface of the workpiece in order to provide a smooth finish. The depth of the face, typically very small, may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes.
