Hello all, I'm trying to set up a Herbert capstan to: Skim 30mm EN8 down to 28mm using a chip box tool on autofeed; Did that, no problem.
Next I need to skim down to 14mm on the same bar. This is giving me a problem. Tried using another chip box but it really struggles and auto isn't an option. It seems to get so far unhappily and then refuses to cut. Upon inspection, the tool is still sharp. I'm running it at full speed 2800rpm approx, loads of coolant.It's almost as if the surface has hardened. Or am I trying to take off too much in one go?
Any ideas? I'm stumped.
