Converted my standard Taig mill's original lead screw,
bearing & nut assemblies to those needed for CNC NEMA 23 motor mounts.
The
Taig CNC conversion kit: lead
screws with bearings & bosses, adjustable bronze nuts, couplers &
NEMA 23 stepper-motor
mounts.
The nylon tubing is cut diagonally (45°) into ¾" long coupling pins.
There are 4
pins per coupler. The diagonal cuts can assist in assembly.
This conversion provided a
precision ground, ½-20 left-hand lead screw with bearing plate & matching bronze
nut
assemblies as spare parts that allowed me to perform a very useful
upgrade to my Jet 9x20 lathe
cross slide.
The NEMA 23 motor mount screws onto
the finely threaded boss & is clamped into place by a ring & set screw.
The bronze, zero-backlash nuts have two (outside) clamping
screws & one (center) locking set screw.
X-axis install. The bronze split-nuts work much better than
expected. White lithium grease is a good lubricant.
X-axis boss & coupler. Do not over tighten the lock nut
as it can bind (break) the bearings that are inside the boss.
Y-axis boss & coupler. Note the four holes for the ¾"
long nylon
coupling pins. A simple yet effective coupler.
Z-axis boss & coupler.
X, Y, & Z-axes lead screws now converted for CNC.
