    Grinding thin aluminum to obtain .02 flatness

    The holes range from .0465-.0492 and are all toleranced at +/-.0005, so drilling is pretty much the only option. Even with drilling the cycle time is long, about 15 hours, as there are approximately 5000 holes. The edges of the holes only need the burr removed, and they don't need to be...

    Grinding thin aluminum to obtain .02 flatness

    Thanks for the reply, that was helpful. The OD of the part is 14.940, so it's a pretty good size. If we end up grinding after drilling the holes, we're going to have a heck of a time deburring the thousands of holes. Any ideas for how to easily deburr these holes after grinding? Thanks!

    Grinding thin aluminum to obtain .02 flatness

    I'm currently working on a project where the print requires .09 thick 6061-T6 aluminum with a .02 flatness callout. The print also requires a few thousand small holes to be drilled in it, all the same size. The problem is this: the material seems to be moving around a lot after the holes are...

    Turning titanium on a CNC lathe

    I'm trying to find out what the best tooling is to machine titanium (grade 2) on a CNC lathe and CNC mill. I'm currently using uncoated carbide inserts and tools. Is there anything that I can use to increase speeds and feeds without warping the part? Thanks....
