The Emco F3 has a removable table that is secured in two T slots that run along the face of the X Axis carriage. This allows the table to be removed and larger items fixed directly to the carriage for machining.
So I loosened the four bolts that hold the table to the X axis carriage and set that aside, this is approx 30kg. I then removed the existing X Axis drive motor and the glass scales for the DRO.
The handwheel at the right end of carriage has two cap screws holding the bearing so I removed these, removed the nut securing the handwheel and removed the assembly.
Because the existing screw and nut have to be replaced, I need to remove the X Axis carriage. I carefully moved this to the end of the travel and dismounted it. This is a large lump of cast iron, 660mm long and approx 50kg, and has a gib adjuster at each end. I made sure to catch the spring and follower for each gib.
With the table and carriage out of the way I could tap out the existing screw and nut assembly and takes some measurements to see what can be fitted.
Photos and options for automation to follow later.
