Hello all, I was hoping for my first post someone could shoot me some advice or any thoughts and suggestions.
I'm a Lab Manager for a mid volume full service lab. We recently starting surfacing poly. I'm having some issues with swirl marks on a small handful of jobs. Its completely random and happens on about twenty percent of my poly surface.
I run a 2G generator with a new blade and motor. A set of 505 cylinder machines for fining and polishing. I'm running a two minute 1st fine cycle and a two minute second fine(17lbs of pressure). I'm using DAC velocity one step pads but the swirls are horrible if I don't two step. I'm running a six minute polish cycle(18 lbs of pressure). My water and polish are chilled to about 65 degrees. I'm using Americal Plus polish.
I have been troubleshooting this for several months but I just can't get it as consistent as my cr39. If this is as good as it gets I can live with it but I'd like to get rid of them completely. Is that possible? Or is this just the nature of the game with poly?
Sorry for the long post.
P.S
I know the 505's are really designed for glass and plastic. Replacing them or my generator is not an option.
Thanks for any help. If any other info would be helpful just let me know.
