What onsrud bit is that? A feed at 30 IPM at 18k RPM seems incredibly slow. I just did it with an onsrud bit 63-530 and it looked terrible - minimum chip load is .006-.008. Your edge in the video looks pristine so which bit is this?
Just to clarify you are sure that is 3/8" material on the acrylic as it looks like 1/4". I am inquiring about purchasing a machine from Laguna right now and want to verify that it is 3/8" material you are using. Great Video Thanks
So sorry that we missed your question. A 40 watt laser like our PL1220 is good for cutting thinner acrylic materials, up to approx. 1/4 inch, but for thicker 1/2 inch material a higher wattage laser is more desirable. Thanks!
There is definitely a lot of difference in your feed and speed for the polished and frosted edge, but I did not notice much difference between the bits besides the brand. Is this an accurate observation?
Hi Joseph, the difference between frosted and polished is the feed, speed, bit, and the number of passes. The polished finish had two passes, consisting of 1 rough pass with an offset and 1 clean pass with a higher RPM and no offset. The bit is generally the same with a slight difference in brands.
I was unaware that it is possible to cut acrylic with a laser. I thought this is impossible with transparent material. Does this also work with a standard cheap chinese 40W laser with a blue beam?
That's a good observation, and the acrylic sheet is laying on top of a vacuum table, which has a grid of channels that can be isolated into sections by using flexible soft hosing that fits into the grooves on the table. It may not be visible in the video, but there are larger holes in various sections of the table that are connected to a vacuum pump that provides suction to the various sections on the CNC table.
@@LagunaTools How many CFM does the vacuum table pull? I've taken a look at your web site but I found no info about it, I was looking at the Samrt Shop M, 4x8 table size, the one that mounts the Italian made spindle.
@@tuscanland There are various vacuum pumps available for our CNC machines. Our sales team will make sure you get the best vacuum for your Maker and needs. Give us a call at (949) 474-1200 and we can help you with any specs/info you need. The Maker 4x8 is a great choice!
Is there any particular difference between those two bits? Since they are both single flute could the Amana bit have just been run at the slower feed rate to achieve the same edge look as the Onsrud?
The difference between the two bits is in the way they are milled. True, they are both Single Flute Spirals, but when you look at them side by side, the Amana is quite different in the way it is designed compared to the Onsrud. It's a good question, and it's best to compare both bits according to the manufacturers specs/feeds/speeds info. Hope that helps!
@@joshwhlr1983 At this time, the exact part number in not known. Most likely the bit is a 63-530. However, you can find great info about all of the Onsrud Solid Carbide Spiral O Flutes at this link: www.onsrud.com/images/LMT%20Onsrud%20Product%20Cutting%20Tools%20Catalog%20PCT-19.pdf and go to: 63-500/Series Upcut Spiral O Flute. There are many sizes to choose from in this product category, depending on your needs. Hope this helps!
@@LagunaTools I wonder if this is the bit you mentioned - I ran this using your exact parameters got no where near the result - but then again you're cutting a different acrylic than I am (likely) but going that slow melts the chips back into it and also adds chatter. I'm using a machine as pricey as yours. Thanks for the info but at the end you're right - bits are very different - which is why its actually good to know what you're using to make your examples actually relevant. The feeds and speeds can't be incredibly different on the same type of tool via different brands.
The methods we show in this video are using somewhat standard (inexpensive bits) that will do a good job of giving an acrylic edge that polished look. However, if super clear engraving is desired on the face surface, then you would have to consider investing in an actual Polishing Bit. Onsrud and Amana have them, but they are about 50 times the cost of the bits we are showing here. In other words, very expensive!!
So is the polished edge on the CNC the same as the laser edge.
The clearest, most concise and detailed video on CNC machining I have ever seen. Well done and thank-you.
Great instructional video. Glad you included the machine speeds and feed rate. Thanks

Fantastic instructional video. More like this please!!!
Glad you enjoyed it! You got it 😎
I have flame polished a lot.
which would be cheaper in this product cutting, a CNC or a Laser cutting?
How often do you replace the cutting bits when cutting acrylic?
This video is amazing. I'm new in cnc world and i dont have a cnc, but i will buy one. Is the 40W laser cnc ok for clear acrylic cut and engraving ?

Every CO2 laser cuts acrylic.
What laser were you using for those cuts? I have a MX with 100 watt tube.
Hey Mike. We are using the laser EX for these cuts, featuring a 150W tube.
How is the material being held on the CNC table? I don't see holes for vacuum underneath the plexiglass, is it temporarilly glued to a sublayer?

@@LagunaTools what bit would you recomment for fine polished edge (super clear - like glass)?
@@ErufenPL a diamond bit, like p106 i think, these bits goes for around $1000 and up..
What onsrud o-flute did you use?
Did you ever find out? I'm curious myself. I've been using Onsrud bits of all kinds and can't seem to get the finish they showed here. Always frosted.
I guess I found a post here where he said it was 63-530 (which is what I'm using and not getting the same or even close to his results).
how thick is that acrylic you were cutting?
Hi there! This is 3/8 inch cast acrylic.
@@LagunaTools
Amazing!!!
@@LagunaTools How strong is that laser?
@@hrodwulf172 This is a 150W laser.
@@LagunaTools Thanks for the reply! Do you think an 80w would be acceptable for acrylic work?
