Continuing the discussion from Toolmaker build from germany:
Today I made my first long parts on my oversized machine.
I made some videos, where you also can see my machine:
Worked quite good.
I got the cheapest set of 7 endmills (3-12mm) for 11€ on ebay from an chinese trader and expected not much !
The 6mm chiniseium endmill broke after 20cm (DOC 7mm).
Then I used the 8mm endmill with 2 straight carbide flutes, which survived all parts. The cutter is still good , no damage or significant wear.
Theoretical feed rate would be around 3000 (0,06mm per teeth), but I went down to 60%.
