Re: Auto tool changers

Hi Ballendo,

I'm not familiar with controllers that want the 'T' word several lines
before it's actual use. And if the machine is still cutting, I don't
see how it can "get ready". This all sounds a little scary to me!

Actually this tool changer is only planned for the ENCO 5" lathe, and
it's close relatives. How could it be used on a mill?
