Brushed Finish Alum.

[Bubba85]

The company I work for is wanting to quote sheet metal alum. with a brush finish. Does anyone have any ideas of how to achieve this finish without shelling out for a new type of machine? We do have a time saver deburr machine I was thinking we could use if the parts come in flat. ( I haven't seen a part or a print yet ) Any advise would be greatly appreciated.

sounds kinda subjective.

asumming a scotch-brite wheel or wire brush over the finished part would suffice.

i would ask if a media tumble would suffice, it it will have less labor.

You can do brushing in your cnc's.

I have just seen a part. It is about five feet long a few inches wide. They want the brush finish to follow the grain of the material, which is making me lean more towards our time saver with a scotch-brite belt. I think a wheel or brush would be too labor intensive.

The raw stock could be brush finish
