Fitting DRO to a Sieg SX2.7 Milling Machine

Part 1 - me looking at the parts and thinking about what goes where....

Now me installing the z-axis:

and mounting the display....

Specifications and some additional images of the installation of the kit: Sieg SX2.7 DRO Installation

I will run some further tests on each axis and plot the comparisons.

Plus, you may have heard in the video me talking about increasing the column stiffness. I'm ordering some parts today and this will be my next modification to improving this mill.

Finally I have finished the installation, now I have a DRO that reads down to 0.005mm in X, Y and Z - and I can switch to imperial at the touch of a button

I now need to get back to making models, hopefully now with more accuracy on the milling machine :)

Whilst fitting the DRO you will have seen that I created a space between the column and the power supply case.

Enough space for a bracket.

And so I created a Sieg SX2.7 stiffening bracket

This has increased the static stiffness by 1.5x :lol:

and yet another video....

Mill Stiffness = Top Finish is definitely true, I made this end mill cut on 2 off 1/4" thick mild steel plates bolted together. I can feel that the vibration on the column is significantly reduced with the bracket fitted and when making this type of cut.
