Has anybody had success milling HDPE ?
I have tried several flat and ballnose endmills, from 6mm diameter down to 1/8" with marginal success. I’ve used my Router with great success - buttery smooth cuts and finish, but the Nomad gives me a stringy spaghetti mess. If I try to take a slightly deeper depth of cut, or stepever, then the spindle stalls. Seems to be no happiness in the middle. I’ve been mostly using conventional milling, but have also tried climb milling and that seems even worse.
I’ve got a couple other end mills I’ve not had a chance to try on HDPE… a few single flutes designed specifically for plastics which have worked spectacularly on acrylic, and some downcut mills for wood and plastic.
Was just wondering if anyone has had success and could share experiences ?
