- Pushing the Samurai 120 past failure! Spindle Stall! 4000mm/min
Today we pushed the Samurai 120 into the unthinkable, and achieved 11MRR in aluminium without flood coolant. These cuts equate to 400% spindle load!
The spindle stalled due to lack of coolant, but the Samurai kept cutting regardless and didn't gouge the part. If it stalled during a continuous cut the spindle servo would exceed position error parameters and automatically e-stop the machine.
It is definitely not recommended to try these cuts on your machine. We crash the machine so you don't have to!

just bought this Spindle and same Servo, can't wait to see it on my Mill :D
where did you get the spindle and how much was it?
@@noone8074go to their website, 1700&
We all want to see in a video.... what control are you using? cause on your webpage mention the nk530m control can be purchase with the machine. so this demos are from match 4 or the nk530?
What is the travel in the X,Y,Z?
Interesting machine, will there be cooling, enclosure, 4th axis support? Such open design will make a mess in the long run!
What control system are you using?
What is the cut area of this machine?
can we use this machine for make bracelets?
amazing machine, fucking love it
Where does the flex happen? Is there a failure point to keep the machine safe from getting damaged?
It’s the tool pulling out from the spindle. The failure point is the axis servo motors. On this machine the safety limits have been increased for testing purposes
Is it better to climb cut? I always thought it was the other way around.
This is a climb cut, which leaves a better surface finish, but should only be used with ball bearing screw machines. Conventional milling is for conventional mills, thus the name.
Nice, but the machine definitely needs a metal bellows for the vertical linear guides and balls crew.
You ever see an older Haas TM? I think covers are a little overrated. Mostly needed for materials like cast iron.
Bellow? That thing needs an enclosure.
@@weltraumprasidentsuperstar5871it needs a bunch of bellows and also an enclosure.
The spindle definitely didn't stall "due to a lack of coolant". If the end mill had gummed up then maybe you could argue that but it looked perfectly fine. Coolant isn't going to reduce the power required for a given milling pass. That's just too big of a cut for your machine.
Josh, here's my question in response to your thoughts here. Why did the spindle only stall at that one position in the tool path? It seems like it takes the same cut on the opposite side of the part without much issue.
Coolant absolutely does promote better chip evacuation by lubricating the tool.
驚くべきことに、日本ではホビー用 CNC マシンの選択肢がほとんどありません。
あなた方の製品が金属を加工して物を作りたい人々の有力な選択肢になって欲しいと思っています。
Very interested to know why you did not choose to use HSK
Would save Z height needed for tool change but I would assume bt to be cheaper
Dangerous as hell, without an machine enclosure
show controller plz
