You will have to mill approximately 0.060" (~1.5mm) off the existing shaft key to make room for the new assembly. The shorter shaft key does not affect performance, as the bearing reduces the amount of torque required to move the axis. This mod should work with all Sieg X2 derived mini mills – Harbor Freight, Grizzly, Homier, etc.

The Harbor Freight Mill/Drill. Some people say not to buy one of these, but to save up and get a "real mill" with a knee. It is the mother of all drill presses, and an adequate mill.

(plus freight) While the Grizzly G0704 may still be considered a benchtop mill (it does come with its own stand) it is very different from the Sieg style machines. First of all, it has more travel.

If you look at my thread that was linked in post #2 it will give an idea of how I did it on my Harbor Freight mill which has similar mounting for the lead screws and nuts when compared to the Rong Fu. For the Z-axis, you have a choice to make.
May 11, 2017· Another issue is that ball screws have less friction, so the travel seed at which you can operate increases with ball screws. A ball screw can let you go roughly 3 to 4 times faster. For a taig, this may not be an issue and for your application may not be an issue, but it is what it is.
