Hey guys I have a few questions I was hoping to get some expertise on.
I am looking at getting a G704 as starter mill and then later get a mtw md001 and upgrade the md001 to cnc with the G704 here a few questions I have.
1) Is the work envelope of the g704 big enough to do this upgrade?( note I may buy the hoss2006 dvd and cnc the G704 first for practice).
2) On grizzly.com the g704 table size in the y direction is 7.125" and the cross travel is 6.875 so is the biggest part I can fit on the y the cross travel or table size or neither. I am looking to machine some plates that are about 9"x9".
3) On most g704's I see the use of stepper motors being used, however on most rf45 conversions I see servos being used with encoder feedback, why is this so common? (pros and cons?)
4) I have seen quite a few bridgeport cnc's most have servos for cnc operation but they still have the handles for manual milling is this a viable option to have both cnc and manual on one machine. what is the reason I dont see this done more?
Thanks in advance for any feed back you can provide.
