Hello everybody!

I'm new to this cnc stuff and i experienced something new yesterday. The endmill shaft diameter was slightly wider than the cutter diameter.
That sound very weird to me as an beginner but others have told met his is normal.

Now I'm machining a prototype electronics case:


Max dept is 61mm and I'm having an really hard time finding an endmill that can do this.
Other than grinding down the shaft of one of my endmills or paying someone to make a custom one for me ... I'm out of ideas.

Having an 4/5 axis would solve my problem but that isn't an option now.

Does anybody know an vendor that has an endmill for this (preferably in europe)

Thanks!

IMO Your approaching this wrong. I would make it in pieces... the four side walls and the one bottom piece with some sort of corner interlock then have it laser welded. We done protos dozens of times that way. Any solid boxes we have done have had large radius ( .125 - .190) on the inside corners designed into it just so you can machine it.

Long neck endmills.... check this site out:

I like the laser welding idea, but sadly that is not an option.
At the moment i'm looking a off the shelf mill and getting it grinded down 0.2-0.5mm from the shaft.
These endmills are available 100-150mm 6mm cutting diameter.
