Re: Re Router / Mill

Dave, the main differences which come to mind are spindle size and
speed and machine rigidity. For comparison purposes, it would
probably be easy to build a gantry type cnc router with 40"x20"
travels weighing in at less than 750 lbs. Mazak built a nice 40x20
gantry type cnc mill for a while which weighs about 15,000 lbs, or
20 times as much as our router. When you look at the comparative
strengths of the materials which these two machines will be cutting,
and accuracy required, there's a fairly good correlation between
these numbers and the comparative mass of the machines required to
successfully work the materials. Without getting into an off topic
discussion of the intricacies of all the various differences between
a mill and a router, suffice it to say that, while the machines may
share the same concept, there are few other real similarities of
detail. Each has its purpose, and each is a poor imitation of the
other when you attempt to use them for other than their intended
purpose.
