ATC module for ER20 spindles

Hello everyone,

I have developed an Automated Tool Changer module for ER20 spindles. It works on the impact driver principle and delivers 35Nm or more of nut-tightening torque, meeting the ER20 spec. Happy to chat and answer any questions. Let me know what you think.

Here is a video of its operating principle:

And here, when I used it to mill an aluminium vacuum holding plate, doing some decent cuts with an 11mm, 2 flute end mill.
