drill at 200+ipm
I mostly cut brass, but do some woodworking. Everything is fine except for simple drilling, in which with whatever drill/endmill or settings I try for hardwoods I get burning. MDF isn't as bad. I have a medium sized router with collets up to 6mm, and unfortunately it is fixed at 10,000rpm. Haven't figured out how to work the VFD yet.
Thanks!

Ah. I've been using much slower speeds. I don't think my machine will go anywhere that fast, though. Maybe 40 ipm.
Thanks
If drilling is a large part of what you want to do, you might consider adding a drilling spindle outboard, which would go a lot slower. You can drill very small holes with your router, but larger diameter bits need to slow down from those speeds - or get in and out a lot faster.

Yes, I don't see a simple solution here. I will see how fast I can run the Z axis - probably faster than I have it set at the moment. Otherwise I don't do that much drilling anyway, so I can simply spot with the mill, and then move the work over to the drill press.

It's Wood,,,???? No need for a second operation,,figure it out by varying speeds,feeds,and cutters
Why have a CNC if your not going to use it ?
Yes,,the above post is spot on,and.......use air
I think I just have my rapid feed setting set way too low (27.5ipm) for the Z axis. I'll see how much I can bump it up. I drill sizes from 3 to 6mm, sometimes 25mm deep, using either peck or fast peck. For wood it seems like the slow retraction speed is where the burning is happening. I do have air, but don't need it for anything else, so I'd sort of forgotten about it.
Thanks!
