Specifications for Glass Bead Blasting
Does anyone know of a specification that outlines finishes (or processes to achieve them)
achievable by Glass Bead Blasting techniques?
We are looking for a way to visually quantify the appearance of the blasted surface (aluminum)for cosmetic purposes. Some time ago, we developed a system at Tektronix, that outlined Bead size and pressure,but alas it is gone.

I am looking for exactly the same sort of standard or specification for controlling the appearance of bead-blasted, color-anodized aluminum components. Barring the availability of any industry "standards", what type of drawing notations or process specifications have been successfully used to help promote uniform appearance of bead-blasted, color-anodized aluminum components?
Any comments are greatly appreciated.

Due to the process variables involved, I would suggest establishing reference standards that production parts can be compared to. If you detail the entire process, you may eliminate some competent suppliers if their developed recipe is slightly different from your requirements, even though their results are acceptable. Colored, textured anodize has to be the most difficult process to control because there are so many variables that effect the final finish. Expect to pay a premium for a quality supplier.
