Acrylic Cutting Help

[Tenson]

Okay well I actually found that my entire Z axis was loose from the X axis. Strangely though I'd have expected that to make the X axis cut poor but that one was great, lol. Still it couldn't have helped matters. I've also made a modification to improve dust extraction. I haven't tried another cut yet, I'll do that tomorrow.

I'm also considering getting a more suitable tool for cutting plastics. Looking at the Cutwell Tools site.. what do you think is better for acrylic they have 45deg Helix flutes (do these extract the chips better?) plus some YG single flute HSSE and some Karnasch cutters. Are the Karnasch worth the extra money?

Never used any to cut plastics but have in Ali and they are excellent cutters. Best finish I've had from any brand cutter so far.

I've just bought a 2mm single flute cutter from cutwel last week for cutting acrylic, 10mm think stuff and ran at 24k 2000 feed 1.5mm DOC the finish is fine but needed some 400 wet&dry treatment not a great deal though.

I didn't bother with a finish pass no real need when I was polishing the edge anyway, it cost £32 or £34 and like a tool it slipped from the collect and lucky as I am hit a metal bolt I use to hold the spoil board down :( still cuts ok but not the same :(

Top tip before undoing the collect nut put a silicon boot on the cutter :)

But I've now change the profile method and use a larger dia cutter 10mm doc taking a finish pass, the edge is spot on, no wet&dry treatment and can be buffed to a shine straight on the buffer.

Can't be seen very clear but the finish is flawless using my new method, I now use the 2mm bit for rapid removal rate and semi finished profile.
