Can we DIY an Industrial grade CNC?

The next episode in the CNC adventure    • Testing the POWER of the Industrial-DIY CNC  

This video: Making a big 'industrial performance' CNC router, that will hopefully mill metals.

This CNC machine needs to earn its place in the workshop, so the plan is to make something that can cut 8 x 4 ft sheets and flatten big chainsaw milled slabs, as well as machine aluminum and steel parts.

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. We will do a whole video on the spindle in the future. 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!
