I love this, I think your machine is a bit overkill for this project though. How about I give you my 3018 and take your machine off your hands. I am literally doing you a favour, LOL Thanks for sharing 👍
If you want to have proper feedrate with a 4th axis, have a look at G94 and G95. (some controllers have a special setting for a 4th axis to compensate this behaviour) The feedrate is wrong by default for rotational movement where the diameter of the moving bit is varying if this makes any sense.
Hi, Much appreciated for sharing this information. Yes we have looked into these settings in the past - this was a demonstration on a customers unit with our standard configuration and the g-code was outputted using a standard post processor from Vectric Aspire.
Would you ever develop a ATC for cnc's other than your own brand ? like a universal mach3/4 atc that came with some assembly required lol, your machines look amazing though :)
Hi, Thank you for the kind comment. We don't usually - we have retrofitted our ATC and control systems on milling machines(ZX45) in the past. Our early machines used mach 3 but we have since moved on.
Hi, Thank you for your comment. We normally use some cutting fluid through a misting system but have got away with just using air on the tool in the past. Cutting fluid or at least air on the cutter is definitely recommend for cutting aluminium and other soft metals.
You can achieve a surface finish that is as soft as silk and with minimal tool marks by: 1) using a cutting tool that has never been used to cut anything but plastic; and 2) using a light spray-mist of water-soluble cutting fluid or denatured alcohol.
Hi, thank you for your feedback. We use and are OEM distributers of Vectric Aspire, which has excellent nesting capabilities but did not feel the need to use in this application since we have alot of HDPE sheet offcuts and prefer all the parts to be in the same orientation.
Hi, This material is a high density fiber board. The part we were cutting was a surfboard fin which would normally be made from a G10 composite. The purpose of the video was mainly to demonstrate the 2-sided cutting capabilities of our machines.
@@kelbrandcamAll machines are capable of double sided milling if you flip your work piece around for the second side. Here are two videos of how I am working on all six sides of a work piece, not only two. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-p2BCw1ORcxQ.htmlsi=LBGR-XwC07OyrQDc ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SXpbHDGDVZw.htmlsi=We8790yXof-z2akH In those video I am drilling holes with several dimensions, milling with several cutting tools and also engraving fine text as well as very narrow tracks. Anyway, I would advise you to fix a better dust extraction system for that fine dust you are making. That dust is really nasty and your vac takes care of only a tiny fraction.
@@AdaptingCamera Hi, Thank you for your feedback. We do offer spindle dust brackets with a 100mm hose adapter for our units, however having the tool enclosed with bristles does not make for a very interesting video. We also put a portable filtered extraction unit behind the camera.
Hi, there are many variables in machining aluminium (Machine setup, tooling and aluminium grade). Every user scenario is different - we normally start with the slowest feed and lowest DOC and increase these values incrementally until our result is desirable. Air and cutting fluid on the cutting tool is highly recommended. Keep on testing and you will get better results, best of luck.
just started to do this 4th axle milling on my machine, same type as yours different brand, bought out of curiosity and turned out to be the love of my life. So amateur 100% here. i just wonder why you use flat endmill for roughing in this case? I only use flat end mills for flat bottom or profile cut. In this case i would definitely use jsut 1 ball head for roughing and finishing, but after have seen this i have the feeling i’m using wrong logic. I hope you can reply, would really appreciate. Thanks for the post.
Hi Thank you for the comment. We're no experts with rotary cutting strategies so the use of the endmill was mainly because we use this approach when flat milling HDPE and aluminium. The endmills we use are designed for material removal so they might be more effective for this application. We've seen that our ballnose cutters seem to rub more than cut when roughing. If the your ballnose cutter can handle the roughing process I see no reason why not.
@@kelbrandcam Thank you for your explanation. The fact is i never even used a flat end mill for this, i will definitely try it on my next project to see the difference.
Nice carve, thanks for putting the bit types with feeds and speeds. It helps a lot! I've been having a lot of trouble with plastic and acrylic, i only have 4flute bits. Gonna change that now.
Hi, I'm glad our videos are helpful. Many good results are from trial and error - We've found that lesser flutes don't clog up as much but using a double flute gives a better surface finish compared to a single flute if you are pocketing.
Thanks, my main issue has just been the plastic pieces melting... I end up with a blob of molten plastic swinging around the bottom of the bit, messing up the surface of the piece.@@kelbrandcam
@@kelbrandcam that's my thought too, im just afraid of overdriving the machine, its so flimsy... the 3018 is fun, but not strong... ive broken a couple bits so far testing feed speeds.
Hi, thank you for your feedback. Many of our enquiries come from customers either wanting an affordable milling machine but not quite ready to take the plunge into a full VMC setup or do not have the space for a large machine. This machine is priced for affordability and is more than capable of making accurate parts.
Hi, a 6mm single flute should be more than good enough, just make sure that the blade length is long enough for the thickness of the material you are cutting, otherwise the shank will rub against the material.
