Mechanical dulling finish

[IngeAX]

Hi Guys, need your help in getting some info in subject above; I have been searching about it and until now nothing...does anybody know what is this finish (Mechanical Dulling), do you have a link so I can learn about it?
Thank you guys

That is not a recognized process name, it just means use a mechanical method to dull/roughen the surface. Could be abrasive blasting or similar.

Thank you for your comment CoryPad, I will research those processes.

There are some standards for cosmetic mill surface finish of materials as produced. I recall descriptions like 1D or 2D being used for the mill finish of stainless steel sheet. I assume the 'D' meant "dull".

Perhaps tumble finish? Commonly use in machine shop.

Yeah, I was going to suggest "vibratory finishing". Throwing the part in the vibrating bowl with all the deburring media stones will give a nice homogeneous scratched-dull finish. Very common.

A "mechanical dulling" finish would seem to imply a process that produces a uniformly smooth but non-reflective surface. A grit blasted surface would normally be described as a "matte" finish. I would agree that a vibratory tumble using the proper media would produce a "mechanical dull" finish. A finish that is both uniform and non-reflective.

Of course the term "dulling" would seem to imply a process that makes a surface less polished or smooth.

IngeAX,

Please define "dull" for us. Is this an anti-glare surface. Is this a laser absorbing finish for an optical system? Is it a cool looking that that contrasts with nearby shiny paint?

It just has to be a mis-translation.

Throw in another vote for vibratory tumble finish from me..

I always liked shell blasting.

Just my 0.02. Worth what you paid for it.
