We have a niagara circle cutter. I've had to replace the cutter wheels once (I believe the machine is close to 80 years old) due to the burring of the material edge.

I'm not sure if you have a circle cutter or a slitter, but our circle cutter is not designed to cut the material in one pass. It usually takes at least 3 passes for 26 gauge, more for thicker material. I just keep a slight pressure on the tightener and as the material makes each revolution I can "feel" the cut.

Large discs of thin material will get wavy as they pass through, just the nature of the material. BTW, you can make a circle cutter cut flat rings by simply cutting the outer circumference first, then adjusting to cut the inner.
