Why is there no white anodized aluminum? (Anodized ...

A gold dye molecule is the size of a golf ball. Blue dye is about the size of a tennis ball. Red and black dyes are about the size of a baseball. Scientists haven't been able to get white dye molecules smaller than beach ball size, which is too large to fit. And that, fellow maillers, is why there is no white anodized aluminum.

Dovetail Milling Cutters | McMaster-Carr

Create dovetail grooves that allow O-rings to flex without falling out of place. Made of solid carbide, they are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from …

The Anatomy of an End Mill - In The Loupe

The overall reach of an end mill, or length below shank (LBS), is a dimension that describes the necked length of reached tools. It is measured from the start of the necked portion to the bottom of the cutting end of the tool. The neck relief allows space for chip evacuation and prevents the shank from rubbing in deep- pocket milling applications.

Then 5 g portions of the powder were placed in a locally built ball mill (Forziati et al. 1950) running at 1750 rpm. The approximately one liter steel jar was chromium plated and 500 mL of stainless steel balls 0.25 in. (~ 6 mm) in diameter were employed. This is considered to be a "vibratory" ball mill in contrast to the planetary type.
