Yesterday I recived a little package from banggood with some endmill for my mini cnc 🙂
I bought some one flute end mill and some 2 flue end mill.
I test the one flute end mill with wood and they work nice. Against aluminium they work really bad… maybe it’s my machine fault…
but the 3mm 2 flute carbide end mill work FINE 😀
3mm 2 flute carbide endmill
you can buy the from banggood
My mini cnc is verry litte and not so rigid… so I have to use very low speed and depth cut parameter.
Want to remember you that my mini cnc use wheel on estrusion profile (like openbuild style) and it use pulley-belt driven system for x and y axis.
You can see a little video collage here
Feed rate 400mm/min
Affondo 0.1mm
RPM: 12000
Cutting diameter=3mm
I have to much vibration… I have to improve the rigidity of the z axis.
But you know…. these are the first tests 😀
not soo clean…
This is only the beginning 😀
Second try… much better i think
Measuring size…
the hexagon have to be 14mm side to side
pretty close
pretty close
the circle anche the hole are the wrost
the cutting surface is pretty nice 😀
There is a uge difference between convetional milling and climb milling direction (like anti-clockwise or clockwise direction).
THERE IS A LOT OF THINGS TO LEARN 😀
