Show"N"Tell ( Your Machines) / 4th Axis for CNC Router
« on: November 13, 2007, 04:29:34 AM »
Here's a 4th axis I built from a 6 inch rotary table and a high-torque NEMA 34. The rotary mount is fixed to and MDF bed and the tailstock slides to accommodate the workpiece. The whole unit bolts down to the table of my CNC Router. A Gecko G203V (Vampire) drive quick connects to the NEMA 34 and safely disconnects when not in use (don't try this with other drives... it'll burn them out!). A Perske 24k rpm spindle (on a VFD) holds the tool. I use either a laser or dial-indicator to true to gantry, that usually takes about 5 minutes.
This setup works great and I can cut using full numerical rotations or via indexing.
