- Demo cut - Samurai 120 High efficiency milling aluminum
You asked for high efficiency milling, here is a steady cut in 6082 with a tool change demonstrating how the single ATC works. The machine can be pushed much further, however the current vise setup is holding the machine back.
Please note the wobble in the ATC arm is because it is 3D printed for testing. Production tool changers will feature titanium components.
Material : 6082T6
Tool : 12mm (1/2") 3fl Merlin
Metric
MRR = 64 cm3/min
Vc = 240 m/min
fz = 0.18 mm/t
ap = 20 mm
ae = 1 mm
Imperial
MRR = 4 in3/min
Vc = 787 sfm
fz = 0.007 ipt
ap = 0.79"
ae = 0.04"

Well, there ya go! Thanks, THAT was worth seeing. I am very intrigued.
As machinist that is used to work with a 39 ton CNC lathe for the most part: Those are some damn impressive cuts for something that you can "throw on your desk".
Tho i'd like to see an enclosure for the thing, especially the toolchanger. I hate divets and dirt in my toolholders or the spindle. Or cleaning up in general.
Also for the wobble in the toolholder i think aluminium should be sufficient, the thing isn't exactly cheap for what it is already.
Nontheless quite impressive!
Thanks! The ATC mechanism has been 3d printed for testing; to see when and how it fails. Real ATC will be made from titanium
Felt like i had to engage my safety squints just to watch this video 😅
Happy to see you finally make it
Oh man.. super beautiful design
Love the sound. Solid machine.
Far from solid, no cast iron used, tiny MGN linear rails with only one row of bearings. The fact that so many features and specs are not listed or shown, the unsupported rails and hidden features here are hugely concerning.
@@blizzardesigns when considering all factors it is a solid (as in well engineered) machine given it has no cast iron and the cuts it is making would make most similar size machines vibrate horribly. I want to give kudos where it is deserved. The team that designed this machine are no fools. I wouldn’t mind betting it has some FEA applied to assess resonant frequencies. Again, I love the sound.
YOU SAID VERY RIGID
Very impressive prototype! Are there plans for an enclosure/flood or mist coolant? It would be great to see a video showing a part run and the resulting dimensional inspection. I'm curious about the surface finish, parallelism, and squareness that this machine can achieve. Finally, does it have rigid tap capability?
Beautiful
Everybody put your hands in the air for the chip confetti
Would love to buy if its 4 or 5 axis.
A rotary axis is better. I need it to make piston and connecting rods for modeling.
What is with the exposed wiring block on X-axis?
Is fanuc control? If yes, would like to buy one to put in garage.
Awesome machine, 6300rpm and 3402mm/min with ap20mm and ae1mm that impressive as fu#k, these MGN12 are more tough then I thought.
Cheers! Have a look at this video, its the same material removal rate on a much larger machine with flood coolant. Listen to the sound compared with the Samurai

@@samuraimachinetools Cool, I saw that video, and just between us, KOR5 not really convince me, like 5 flue endmill for alu? for finish? ok maybe, but for roughing? mehh. Anyway your strategy looks and sound much better, in titan video we can evidently hear tormach induction?? motor struggling. funny enough I believe if they use some good 3 flue endmill they would get same MRR while putting less stress on motor, by generalizing: 5 flue make smaller chips what mean that material need to be cut more= more power needed.
BTW I don't have experience with Merlin brand, but let me tell you, I bet that with 3fl. Garant Master Alu you could go even faster for your demonstration purposes😉. I don't know what kind of vodo Garant put in this endmills buy they CRAZY stable , Like you could get at least 20% more MRR and with synthetic oil mist😉something like 30-40% more MRR, That just my wild guess by watching how your machine own stainless in your other video. Anyway good to know that someone who know his sh#t finally build some decent desktop?? cnc. Take care.
what type of servo motors are in this unit?
Hmmm...must be a work in progress still. Without some form of shielding, those tool holders will be covered in cut chips, which will make tool changes impossible. But it does still look like there is more to come.
Well I've seen an NC Bridgeport with just air cooling and chip vacuum.
@@billmorgan6110 That would never be sufficient. I run two haas mills with the tool turrets inside the milling chamber.. They have air blast, but it's not uncommon for the tool holder to get cut chips inside and then a fault in tool loading to occur. mills with the tool holder on the outside are much better.
I’m surprised the workpiece didn’t fly off device. It looks like he’s holding it only from two points and very small ones at that.
Nice machine. I see nozzles near the spindle nose. Air blast? Flood coolant? Mist? Any plans to add way covers? What kind of protection is in place for overtravel?
The machine has 3 coolant options including TSA, flood coolant and air. Full way cover protection is available as an option, so the machine is being tested with no Z cover. Just soft limits for over travel.
Wanting to buy, couldn’t find the machine page just a cnc kit, couldn’t find also a coolant options .
Thank you for your feedback. The machine is now available with electronics
Build legs for it so it can walk around the shop.
Why not cover the machine ways to protect the linear rails from chips?
The most important part, the y axis is protected. Protecting the lower part of the Z axis is not as crucial so we offer this as an option to keep costs low. If you look at some competitor machines they offer no way cover protection (not even as an option) and show coolant everywhere. That will certainly cause premature wear.
You know that the integrated motor case is not chip safe - chips might enter the housing and cause a short on the motor. Chips are nasty over time they will go everywhere. Vibration and the amount will take care about that.
How do I know - it happened to me.
I have also built my own CNC.
Our motors are sealed. The default ones have no protection on the encoder housing which would explain the issues you had.
I think he’s referring to the connectors that appear to not have any kind of seal.
I mean you have an open unpopulated connector that’s just begging to be shorted out by a chip. Do you have plans to seal these connectors on machines you ship to customers?
@@joshuahuman1 I wrapped thick plastic around the entire JMC motor (that's what they're using). It protects the entire thing of coolant and chips.
This machine can be considered as a "better quality" mini mill. But they seem to be new on the market I see flaws I ran into when I made my own mill.
No coolant setup is a strong no go for a CNC mill. Contour milling is easy since the chips will just fly around - and spread all over the room (who's going to clean that?) We add some thick transparent plastic around our mill that will catch the chips.
Demonstrate 4-8mm slot milling for 20-30 minutes with that machine, or deep pocket milling in aluminum with 5-10mm.
Those issues are solvable - but it seems they don't handle it properly yet. For >5000$ adding a few extra bucks for a coolant system that should really be included.
@@joshuahuman1 Yes, wire connections should be in a sealed box with rubber seals around cables into the box. Pretty standard stuff. I hope this is an early prototype.
@@benargee The Z axis should be covered. The linear rails / the screws aren't covered, if chips are stuck there they might end up inside the linear guide carriage (it should be fully covered).
Just a few more items to fix, all doable at least.
(correction it's not easy to see but there seems to be no slot around the ballscrew behind which could collect chips)
Put covers on the CLS / servos. Trust me. I killed the voltage regulator on one when a chip got in there and there are no replacement boards available...
Our servos are sealed to prevent the issue you experienced. There are also M3 mounting holes for an additional cover
No 3d machining? Do all three axes in one op for a helix!
Tool. Cover !!!!!!!!!!
It bothers me more than I prefer to admit, that the "t" in the channel name is lower-case.
Mill some plastics
could I have one for free my good sir
