I am embarking on building a high-speed cnc router table. I only need a work envelope of 24" x 24" x 6" in the xyz. Actually the z only needs to be 1" (.5" cut depth and .5" clearance). I have two machines, since they are general use, they are not designed for high-speed. I am cutting wood only to a max. z of .5". I am looking to cut at 600ipm and up with 1/8" and 1/4" shanked bits. Right now, 180ipm is as fast as my 4' x 8' x 6" router table with steppers can go. Since my loads will not be great, I am thinking a rigid, but light gantry and high speed spindle with servos will get me where I need to go. Anyone have info. on cheap servos and drives? Also, accuracy requirements are not as tight as my metal cnc machine. I can probably get away with +-.010" (.020" total delta). Great forum.
Thanks,
Rob
