He got talked into that machine by a former rep and told me that he now regrets not getting something a little more sane. Apparently, it doesn’t cut your standard sheet goods or 8/4, 12/4, etc. lumber very well. The way the rpm range is geared on that thing, even dialed up all the way, blade speed is not quite fast enough to get good cuts with 12” or 14” blades. This never would have occurred to me unless someone mentioned it or, I guess, I ran into it myself but point being, machines this size/spec are designed for a specific task and in the case of the K590E or that Martin, it’s for cutting huge architectural timbers with an 18” or 20” blade, not our vanilla 12” or 14” blades.
Now, I suppose the VFD could be reprogrammed but regardless, this thing is a Formula-1 car and there wiil be a price to pay for trying to make it a daily driver. Since dado got mentioned, how will it cut with a 10” dado stack or even a 300mm slotting cutter? You want run an 18” blade on it for everday use? Everyone’s wallet is their own and they should buy what they want but the rubber hits the road at some point.
