TCT Router cutters in a mill running at 4000 RPM

[m_c]

One thing worth mentioning is you really shouldn't machine wood on metalworking machines, especially ones that aren't well sealed.
They really aren't designed to handle the inevitable sawdust which will work it's way in to places it shouldn't, and clog things up.

Hi m_c

Tar very much for letting me know you shouldn't machine wood on a mill. Themanual says that you can machine wood on it but with what you have said I willnot do that the last thing I want is to damage my machine. I will go by whatyou say having read many of your posts. Thanks again you could have saved me alot of trouble.

All the best

I once cut plywood a wind turbine blade on my milling machine with a TCT router bit, long before I'd made the CNC router. Due to the potential problems from the dust I taped paper to the machine to stop the dust getting on the slides too much, then cleaned and oiled everything thoroughly afterwards. The chipload can be kept quite high - I used something like 0.2-0.3mm chipload at 2150rpm. I think it was a 1/2" cutter. The milling machine is obviously very strong compared to a router, so you can push it quite fast. Not something I would do remotely regularly though...
