Low Speed Engraving

[TaK]

I'm looking at engraving some small letters on a decorative piece of aluminum. The problem is that my X3 only gets up to about 2000 rpm. Can you engrave at this speed and get a nice finish? Is it just a matter of a super slow feed or is the only option to build an engraving attachment for my mill?

Any recommendations are appreciated.

Thanks

Of course you can engrave at 2000rpm you just have to feed at a slower rate.

It would be worth getting a high speed spindle if you were going to do this a lot.

If you end up doing more engraving, you can make a bracket and attach a high-speed trim router that will run 25,000-30,000 RPM. It's a cheap way to get high speed.

I recently upgraded to an Air Turbine Tool that runs steady at 25,000 RPM with good power. It runs very quietly. It does use a lot of air, though.

we use a special attachement (it goes as tool into spindle) for RPM rise.
