4 Axis Spruce-up

I have found a good project for my 4 Axis CNC mill and also my Rhino 5 software. If you have read  recent posts I have mentioned I am pursuing carving some small bells from wax for lost wax casting. Here I am re-configuring my original Taig micro mill back into 4 axis operation.

I need the tailpost to be able to slide into any length position I need. The stock Taig slotted table is perfect for that. I don’t need the multi hole set-up table for 4-axis. I set the rotary table up so I can just slide the tailpost against the back of its slot and it is in perfect Y alignment. The height is taken care of by the shims and the small adjustment in the tailpost itself.  After this set up it will be a very quick reset for the tailpost.

You can see I have placed a Chuck adapter in the middle of the table. I will use that (with a chuck) to hold the wax cylinder as I mill out the center of the bell.

I have a few seconds of video I made of a dry run of the 4-axis profiling run. It makes some interesting sounds as the X axis is moving very slowly and sometimes “jiggling” a bit. Not sure why, but it is playing that CNC music. You will have to imagine all the missing parts. Hey! Just do it!  🙂
