Surface finsh for anodizing
Surface finsh for anodizing
(OP)
I am working on a prototype product in aluminium 6082-T6. Machined cube about 4" with flat faces and rounded corners.
I wish to clear anodize and would like to achive a smooth, flat blemish free finish that wont show finger marks too badly.
What would be a good surface roughness to achive this? I am concerned about machine marks and blemishes caused by polishing.
Dont want to bead blast or linish.
Thanks

RE: Surface finsh for anodizing
Clear anodizing produces a somewhat matte surface finish. But it won't obscure texture features of the base metal surface, such as machining marks, grit blasting or sanding scratches. If you want a smooth, uniform surface texture you might consider giving the part a vibratory tumble finish before anodize.

RE: Surface finsh for anodizing
Anybody know of a reference I can go to for anodized finish like RAL code painted colour? Only in this case there is an element of surface roughness , texture and visual appearance.
Trial and error seems to be only method available to me at the moment. I do not have my pick of vendors due to my geographical location.
The anodising shop can do some pre-treatment to obscure surface blemishes. Textured bead blasting which is not the effect I desire. Linishing with a sand belt produces a grain in the surface which is prone to finger marks and oil.
Polishing the surface seems to bring out machine marks. Perhaps a different grit size or polishing process should be used.
Perhaps some other process will produce the effect I want. I just don’t know because I cannot un-ambiguously define it.
