jdm61, the link is just a demo of the 5 axis head range of motion.
The actual cutting speed is based on material thickness and the edge quality desired and does not move that fast in actual cutting conditions (unless we're doing foam).
Knifemakers steels are thin so cutting speeds are still real good.
The accuracy is only as good as the motion system, the machine I have have coming is top of the line and will produce very clean accurate parts.
Bolt holes are no problem but dowel pin holes will need a reamer to make em sweet.
I routinely cut tap drill bolt holes in > .25" thick aluminum details that can be tapped without additional drilling or reaming.
This isn't the answer for everything but sure does give me a powerful capability.
I like making knife blanks but there needs to be some volume in order to make best use of our machine time.
Prices are base on the economics of scale, prototypes are more expensive vs cutting full sheets.
