I am currently working on two new projects.
1. An automatic tool changer for my CNC lathe.
2. An injection molding machine to make plastic parts.
On the tool changer I bought a heavy duty tail stock turret attachment for
my JET 13X25 lathe. It has 6 posistions. I plan to drive it directly with a
nema 34 stepper motor rated at 150 oz inches.
The tool changer will be for those pesty jobs where you have to center
drill, step drill, step drill, ream and chamfer. The key was to find a 2
degree per step stepper motor . This makes dividing the 360/6 easy and it
comes out to be an even number.
I am figuring that with everything on center that there should be little
forces trying to make the turret rotate axiallly for the lined up posistion.
The radial forces are dealt with within the turret attachment.

Projects finished.

Adding a servo system to my mill drill
Solving the mill/drill quill backlash problem.

BTW the DRO boards are on order and the scheduled date is 6-24.
