Thanks for link,Nick. Evry day is a schoolday. Otherwise concur with JS provided a finishing hatchet is used NOT the roughing hatchet used for remodelling H & S inspectors..

After I got the feedrate right, thank you Andrew, I now feed 4mm/second and cut 370mm 25mm thick Aluminum in 90 secoonds, with a saw 125x2x27mm 72T at 600rpm, I see no reason to use a cutting disk for this kind of task. The finnish is really good. As long as I can put it on the mill table, I'm OK. If it's too long for that, I'll guess I will get a Aluminum cutting disk for the angle grinder.
 
I think cutting oil is a must though. I'm using rapeseed oil with no additives myself.

You get a far better finish with extra virgin olive oil.

extra virgin at about 10 times the price of rapeseed must be for gourmet mechanics running RR's

Rigid workholding is of utmost importance. Vibration can easily come from a flimsy setup.
