Tips for drilling wood?
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!

Re: Tips for drilling wood?
Ah. I've been using much slower speeds. I don't think my machine will go anywhere that fast, though. Maybe 40 ipm.
Thanks
Re: Tips for drilling wood?
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.

Re: Tips for drilling wood?
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.

Are you peck drilling, it helps a lot in keeping the tip of the drill cool. what size holes are you drilling?Originally Posted by robobass

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
Re: Tips for drilling wood?
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!
