Re: Acrylic machining edge finish…
Thanks for the reply's.
Could that also be stepper noise? Meaning that the steppers movement is leaving those marks as they are very consistent... this is a rack and pinion machine but very stable, acrylic shouldn't really be a problem for it.
I've been using shallow passes .125 so no swarf has been even close to welding. Tool stick out has also been minimal since this is only .500 material, so I have to think its not toll deflection.
Spindle bearings I hadn't thought of, this is a relatively new spindle with very few miles on it but it is Chinese.. how would I check for a bad bearing(s)?
Also, could I use a .500 multi-flute bit for finishing while I'm running a finish pass @ .008?
Thanks for the input.
