4 axis DRO
T Axis installation
I attached the T axis scale to the right side of the mill.
This was a challenge in that the column on the
mill is not square. The bottom of the scale is bolted directly to the side of the mill. The top of the
scale had to be spaced out to match the reader head as it travels up and down.
Completed "T" axis scale!
I first attached the scale to the side of the mill. The reader head faces the rear of the mill.
I used a dial indicator to check alignment of the scale as I raised and lowered the knee.
You don't have to move the knee very far while watching the dial indicator (couple of inches).
Once I was satisfied with the vertical alignment of the scale I marked, drilled and tapped
the top attaching screw for the top of the scale.
I now had to do the same thing with the dial indicator to space out the top of the scale.
The scale is now aligned with the knee (not perfect but very close).
Spacer used to get proper spacing at the top of the scale.
I cut out a template from cardboard to get an idea what I needed for attaching the reader head
to the knee. (sorry for the blurry pic!)
I cut a bracket from 1/4" steel. I used my hydraulic press to make the bends.
I then drilled and tapped three 3/8" holes to attach the bracket to the knee.
I left enough space to allow for a coolant / chip cover to be installed.
A chip / coolant cover is really needed here.
Bracket painted and installed
Because of the top of the scale being spaced out from the mill the included chip / coolant
cover would not fit. I made my own cover from 1 1/2" thin angle iron.
I also used a thin piece of 1" angle iron welded to the side.
