Nice. Making deep cuts like that, though, you're really going to want some coolant / lubrication, a mist coolant setup is probably the best way to go I think. WD40 is OK for cutting aluminium but useless as a cutting fluid on steel. Pick up 5L of soluble cutting fluid and a mist setup, you'll be good for years. If you look at the deep endmill cut at 9:27, the chips started off relatively cool, but moved to straw coloured and by the end of the cut they were coming out blue, that's a pretty good way to kill an HSS endmill.
Thank you for advice! Yes I'm planning mounting a coolant system, now the table is ready for that, have the holes for coolant fluid. At the deep endmill cut i use carbide roughing endmill and is a mini beast :) hard to kill.. i have many many hours and still sharp as a razor blade. Carbide is an incredible material. The reason of coloured chips is due to endmill got very hot?
@@kvechannel The colouring is due to heat buildup in the workpiece and the chips coming off hotter and hotter, for them to come off blue they're at 300°C or so. I hadn't realised it was a carbide endmill, they're generally fine as long as the cutter itself doesn't end up glowing :) (slight exaggeration, don't do that)
Very nice. One of the higher quality mill builds that ive seen.
Thank you!
Carbide tooling cuts so well. Way sharper than my 15usd HSS endmill set.
El taladro más simple que e visto y muy padre con mucho precisión .👍
