Re: [CAD_CAM_EDM_DRO] Air Powered Spindle

It works great for grinding. I have a air spindle for grinding spade drills on drill blanks (cbn or diamond coated bits).

Never used it with an endmill. I would expect my air spindle to have a minimal load as in grinding, it's not a strong tool. I bought an expensive one, (but in comparing it to the harbor freight version, it is the exact same looking airtool, but we bought it in an axa tool holder( but I have never used the harbor freight version)

Hope that helps.

Does anyone have any experience using an air die grinder or similar as a high speed spindle? I need to be able to run up to a 1/4" end mill and will only have air available for power - no electricity! I'll be cutting aluminum slots that are ~1/4" wide, 1" long and 3/8" deep. I'd like to be able to cut 1/8" deep per pass, but could live with less. This will be as a live tool on a lathe - no Y control, so I can't effectively use a smaller end mill with a pocket.
