So, I took a temporary detour while working on the 7 x 10 CNC project and decided to build a tool indexer.
I had to do something with the beautiful little NEMA 17 motor from the dead HF micro lathe fiasco. :violin:
This tool indexer will hold (4) 5/16" tools. Indexing will be controlled with a 3rd axis on the G540. The 4 center drill spots in the front of the tool block are not utilized. They were originally put in for another ratchet option, but changed my mind on that design.
Looking at the front of the tool block, it will index in a CW direction. A modified 3/8 ratchet will be mounted on the back of the motor, locking the tool block from rotating back CCW. I'm working on the assumption that the indexing program will rotate CW 52 steps, then CCW 2 steps to lock the rotation against the ratchet. Sounds good in my mind, anyway.
