When might a single spiral flute half inch shank be to much for a router?
Is there a better bit to be used on firm rubber like plastics?
The guy that runs the Nextwave Branded CNC (just retail marketed DIY stuff) insists that a job we do, cutting these soft rubber like plastics, must be done with the 1/2in single flute. That while other bits can be used, they can only be smaller, meaning longer time per cut. The trouble is we also insist on using ONLY routers that Next Wave signed off on as being acceptable for use on the Shark CNC machine, so a particular model of Porter Cable is the only one we use. But since they upgraded the model, it now catches fire when using the half in bit. Sometimes sparks, sometimes smoke, sometimes it just stops spinning. I speculate the bit is pulling to much strain on the bearings and in turn is effecting the load on the internal power regulator, which is likely just powerful enough to handle the expected load and not power through. It’s the best theory I have. I know router doesn’t have the same quality of parts that a spindle does.
Although I don’t like the controller, or the drivers. I do not believe they are at fault with this failure. I do think the Router model is a problem, but thats more an internal argument. Though I don’t mind if you have tips, or experience to share on the mater. I can pass it back and hopefully we can move on.
