Here you can see the first part of my building report for my BT30 tool change spindle. I am very curious how that will work in the end. If you still have important tips that can still be implement let me know! :)
I bought the plans of the spindle at bauanleitung24.de. The plan serves me only as a basis. I have changed a few things to make the production to easier and also make it feasible at Unit 1 (if you do not have free access to all machinery).
The material of the spindle shaft and inner parts is 1.2842 or 90MnCrV8.
