OT I know but I need a little help. A friend needs a piece of Bakelite engraved which is to big for my machine. It is for antique radios and requires a logo and dial engraving. Any takers?

Cheers,

Andrew

Is the engraving to be on a flat surface or a rounded uneven surface.
Most of us could handle flat, but a rounded surface makes the job much more complicated.
BTW what side of town are you as I will then be able to suggest someone closer.

I am in Ringwood Melbourne.

I need to get a little more detail from my friend. I am of the understanding it is a flat panel.

If you have the cutter I can engrave a piece x axis 1150mm y axis 600mm z axis 140mm. Using mach 3. I am based in Beaumaris.

Thanks for that. I have engraving cutters that are .2mm tip on a 3mm shank.

The Bakelite is 4mm thick and 382mm x 192mm. What format do you need the drawings?

Cheers,

Andrew

DXF is fine if the contours are constant depth. If if is not you will need to generate G-code for mach 3. I have a 3mm collet and can run at 24000 rpm. It would be best if you had a test piece we could use to set speeds.
