Abusing an industrial-DIY CNC

In this part1 video we experiment with and learn about the big DIY concrete CNC machine we built. It's powerful and fun.

Part 2 is here! https://youtu.be/O4sJTCd2mig

The 3D model of the cam-clamps is here (it’s in the shop but free): https://ko-fi.com/floweringelbow/
3D CAD model of the CNC machine itself: https://ko-fi.com/floweringelbow/shop

To see how this CNC is made watch this: https://youtu.be/cqYJS27aC4w
Veg oil – diesel conversion video: https://youtu.be/_dNTMqf5nYM
For the easy DIY aluminium heat treatment: https://youtu.be/z5ejhb1t8BY

In the MQL system I'm using a ratio of:
1 filtered waste veg oil : 1 water : a dash of eco dish soap

The spindle motor in the video is a 240V single phase Jianken JGL-100mm 3.2kw 24000rpm BT30 ATC. It has ceramic bearings and thus far seems very very nice. We chose a 4 pole one, which has somewhat more torque at lower rpm than the 2 pole, but requires an 800Hz VFD. You can find them here: https://jianken.en.alibaba.com/ and if you do buy from them, message them and mention 'Flowering Elbow' to get yourself a discount!

The endmills and tool holders used in this one were from DGNZNC, a seller on aliexpress you can see here: https://www.aliexpress.com/store/4650128?spm=a2g0o.detail.1000007.1.3613389fBalW0C they work, and are such exceptionally good value it's not a disaster if you accidentally break some (luckily for me!). If you mention 'FloweringElbow' they should give you a 5% discount.
