    Hi

    I'm looking at ways to mill a groove in the saddle of my WARCO WM16 Milling machine in order to make a bit more clearance for the x axis leadscrew... Does anyone know if this might be possible with a router and metal cutting burr at the lowest RPM setting and plenty of suds?

    If no-one knows then I guess I'll just give it a try on something non-critical...

    Thanks Jo

    Bump...

    Did no-one try this? I admit it sound a little bonkers... but I thought that if I use a grinder to remove the majority of the material I could use a grinding burr to finish up...

    You could use an angle grinder to get the bulk of it out and then use a hand router with a carbide milling cutter in it to get it nice and flat? You can use a CNC router to cut Cast Iron (others on here have done it, I've even cut steel with mine.....slowly!) so no reason (apart from being scary and having lots of scalding metal chips flying around!) why you couldn't.

    Hi Jo
    As Neil said a rotary burr will do the job, my only experience is using them in a die grinder on steel, throws out nasty needles that get everywhere, cast iron should come off more like powder, make sure you have a good quality mask and adequate eye protection, it's nasty if you get it in the eyes.
    Good Luck

    Thanks guys!

    Yes that's exactly what I had in mind!

    I used to have a Dremel which I might have used to finish up with but I gave it away to my daughter who carves wax for lost wax jewelry castings with it now...

    I'll let you know how I get on and post it up in my build log.

    Oops, forgot to ask is there any particular kind of burr/cutter I should be looking at using?

    And do I need lubrication?

    Thanks

    Don't know if a Dremel would be upto the job anyway, we used 6mm shank burr.

    Should be ok cutting dry, will tend to clog if you use something oil based.
