- Here is my 6040 cutting aluminum. Please checkout my part 1 video for an overview of my setup.
6040 CNC machine review of my setup and some helpful upgrade options. I have upgraded my machine with a Gecko 540, limit/home switches, jog controller, bigger collet set for my ER11 spindle (up to 1/4 size), air nozzle.
You can watch part 1 to see a general overview of my setup along with some of my upgrades • 6040 CNC review of my ...
Info:
6040 CNC with 800 Watt spindle
feed rate = 300
plunge rate = 50
spindle speed = 400 (max for my VFD 24k RPM)
Note these speeds are what I am using in the video I have ran the machine faster and it works fine but I don't mind waiting longer and knowing the feed rate will be good. I am sure you can increase the feed if you wanted but I would start here if you are just learning
Jog controller is a XHC HB04
Controller is a Geko 540 with 48v power supply
I'd strongly suggest using an HDPE spoil board, it will reduce the harmonic vibrations dramatically. Just get a sheet of 1/2in or 3/4in, cut some slots to match your deck and skim the top so the surface is true to your machine rails...i did exactly that on my 3020 and it made a world of difference...Google 3020 mods and upgrades, you'll see mine on cnczone. Keep the videos coming, thanks for sharing :)
Ouch, that vertical feed really pained me, spiral your way down mate!
Set your RPM to 17K, your DOC to .005" and your feed to 75IPM. Plunge at .5IPM
See if you like your machine quieter, your cuts cleaner, and your endmills lasting longer.
Is that endmill a center-cutting one? I'm no expert but the plunges are chattering bad, try helical paths. The spindle speed is far too high, cut at 8-12k RPM or take the chance and feed faster. Any rotation of the tool that doesnt *bite* into the metal hardens it so it gets harder to cut the next pass. Eventually it does bite but your making aluminum powder not chips. I just got my Chinese spindle 2.2Kw so I will see how I get along. lol. Great videos overall, both parts 1 & 2. Cheers!
I was just about to say the same thing!
You shouldn't have surface burrs like that if you are CUTTING rather than rubbing the workpiece. I made a servo mounting plate for a model powerboat. It took me FOUR expensive attempts cutting the 8000 series Al I had before I go the settings right.
Next time I'll practice on scrap pieces instead of stupidly expensive aerospace grade material.
Aluminum does not work harden.
Not true. Most grades do, though some do not. www.totalmateria.com/page.aspx?ID=CheckArticle&site=ktn&NM=163
Yes when I made this video I was very new to building toolpaths. Since this video I have upgraded to a vertical mill and am very good at using Fusion 360. I need to make some update videos. This one was mostly just me learning the 6040.
@@codysinger8706 yeah fusion 360 is where it's at. I tried others including Solidworks with other CAM add in's but always came back to f360.
Wonderful video for us prospective 6040 owners to see what the capabilities of the machine are. After the design in Fusion 360 what is the procedure to get the design to the 6040... I assume there are some intermediate file conversion steps? You have a really nice looking shop... very well set up! Thanks for the great video...
Thank you for the comment. There is an included post processor included with Fusion 360 and it works perfect. I will work on a video of the full process of getting from Fusion to a real world cut.
Really looking forward to this video. Thumbs up
Hi, i have the same machine (same frame). Did you have meared the deflection (bending) of the X axis (40cm part of the frame). I have 2.2kw spindle and its hanging over like you described in the first video, but only in the center.
Sounds like you have bent guide rods, if its strait at the ends and tilts in the middle.
Where did you get your 6040? I'm in the same boat you were, but I have been unable to find anyone that sells used machines. I am not a woodworker, I'm just a disabled guy who wants a hobby!
What is precision of such 6040 CNC Routers from China? 0.05 mm would be great. The frames are from Alu or steel?
We’re can I buy the machine
Cody, could you disclose the vendor name if possible?
Sprayy sum wd40 while its cutting every now and again
Hia everybody my name is Patrick and i have a 6040 cnc cutter and im struggling with the set up its all connected to my dell computer and i have mac 3 loaded i am very new to this even though i have looked at video after video i cant move my axis with the key board with the arrows you could say i need help thanks
did you get it running yet? Need help?
what are these cnc like for making perfect circles say 70mm in dia
wonderful.
Thats a terrible edge finish, try single flute cutter, 24000rpm, 1500mm/min feed rate
Appreciate the advice. I was just trying to get familiar with the machine.
mach 3 on Windows 7 ???? HOW
probably with a smooth stepper. works fine that way.
I run mach3 in windows7 ans windows10 any problem
cody, each cut 4mm?
+Nurfat Rochman I am only cutting about 1.2 mm each pass. The way I had the piece clamped down vibrated too much going anymore than that and I was also in no rush.
+Nurfat Rochman here is a link to the g540 with power supply that I have. www.ebay.de/itm/Gecko-G540-Controller-current-version-with-48V-7-3A-power-supply-/161067796626?hash=item2580638892:g:HVEAAOxyaFtR5YM3
cody singer thanks cody, nice information
I have yet to see anyone machining aluminum correctly on a router. you are going to damage the spindle with all that chatter and down pressure.
ramping circular interpolation +.01 on the wall, the finishing 2d 0 on the wall. sho makes the bearings and endmill last.
Oh my god that sounds disgusting... You can literally see the huge vibrations. You are milling aluminium extrusions with an endmill > RPM down and Feed way more up. For those you can use Feedrates up to 1000 mm/min and RPM ~10000. That should eliminate that vibrations
Thank you for the advice. This was still in the stages of me learning and using BobCad was not as controllable as I hoped (it was an old version 22 though) I need to make some new videos of this cutting using Fusion 360 I now have spiral plungin and my feeds/speeds figured out. I ended up getting an older Novakon NM135 upright mill which is way more capable so I dont use this CNC much anymore.
WTF :D
the feed is way too slow creating a harden skin on the material
Slow down your rpm circle it and move down at the same time don't plunge a endmill this is painful to here. I do this for a living at least kick up the feeds. The endmill will come with recommended feeds and speeds just look on the packing it came in
max cox man, I am watching it after struggling with mine haha. I used 6mm 2 flute flat end mill, and it wasnt that bad actually. Lots of vibrations from shitty frame tho. I first spiraled 10mm inside a part with 0.3 spiral angle and then machined the whole depth in once but with 0.1mm at a time. And it wasnt too bad actually. Had to bump up rpm all the way up to 16000 almost tho. Probably wrong, but lower value didnt sound right at all. And feed was like 300mm/m or so. Have to play more with it. That aluminum extrusion floor is such shit tbh, it is a part of a problem for sure.
I feel as if my ears were just raped. You should be able to get some feeds and speeds from the tool manufacturer. Also there is tons of info to figure out the math and or you can get a calculator for determining them. Also use the shortest tool possible. The right feed and speed will help your wallet out too and not just your ears as it cuts down on tool wear.
Most of this noise was coming from a crappy fixture job but yes I had a lot to learn on this machine. I have gotten it cutting much smoother now.
Don't feel bad we all have been there. I can remember breaking 4 end mills in a row and at 25 a pop yeah that was a fun learning experience lol.
pprotory Yes, this is my new favorite comment on TH-cam
Can it run with higher feed rate?? Looks like the machine can run a little bit higher with that spec and frame. Yours is slow.
square tubing stock, Not bar stock
nice machine, wish i had one and the space for it
nice work.can you please please helo me with my 6040 setting it up.i got it working but i need some help with limit switches.thank you
hello greetings from Venezuela, which spindle recommend for aluminum engine, and if air-cooled or water hp? wat? Thank you
Amazing video and I hope you can answer this question.
Did you get it done with exact dimension? I mean, this machine reached or not the precision you were waiting for?
something is wrong with your camera.
are you running via usb or parallel ?? maybe I missed it..
Parallel on the Gecko 540's I would like to find a USB controller but I made it work.
can you share link where you bought this machine ?
Need lubrification..
