I have a Suburban Fly cutter and their 5" bar . I started getting familiar with it by facing off all my aluminum chill blocks. Roughly 4"x5" one inch thick 6061 blocks . The fly cutter works great but I have to run it in low range in my mill, which is 370 RPM and slow table feed . I can run it in High 1 which is 650 RPM and it makes a nice finish, but it has some wobble vibration that i'm not comfortable ...think washing machine on spin cycle ...but not quite that bad. My mill is a PM940 , not a mini but not real heavy either .
I was thinking about tapping the back end of the cutter bar for a bolt that I could put weights on to counter balance the thing , maybe washers , drilled brass or lead weights ??? I donno , just kind of mulling around the idea .
Anyone have any thoughts on this ? Here's is a short vid of some old vice jaws I welded in some deep cuts, gouges and dings . Roughed off the welds with and end mill flush to the original surface, then took a 0.005" fly cutter pass and another pass at 0.004" , both at 370 RPM and slow table feed.
Any input is appreciated , Thanks !
