RoboDrill vs. Traditional VMC

As I have been told, the FANUC RoboDrill is typically 20-60% faster than traditional 40 taper VMCs, depending on the part. These are pretty large numbers and hard for me to comprehend. I did like what most do and first look at the traverse rates, while 2,125 IPM rapid traverse is fast others might show a faster rate. Then I started looking into the "grey" specifications to try to understand this. First, tool change time. Most believe automatic tool changers are equal. FANUC builds their own "turret style" tool changer, utilizing a FANUC servo motor, tool change time (tool to tool) is 0.7 seconds. Next, I looked at the acceleration / deceleration. FANUC specification states 1.5 G on all three linear axis. Again this is a spec that sometimes gets over looked. Several years ago, acc/dec was further defined as how "quickly" you can get from point A to point B. 1.5 G on a FANUC RoboDrill is equal to full rapid movement in less than 0.100" movement or a 20" movement in less than 0.5 seconds. I sometimes wonder when FANUC uses their 31i-B5 CNC Control, is the RoboDrill a test site for the latest and greatest technology. It makes you wonder why such a powerful controller is used on a simple drilling machine. Again, utilizing technology to shave seconds.

Watch the video of a 10,000 RPM spindle FANUC RoboDrill side by side to a "traditional VMC" - over 37% faster cycle time on this part. With labor rates rising, the expense of floor space becoming more critical and the push for more efficiencies, why wouldn't you consider a FANUC RoboDrill?
