An Improved Quill Feed for a Sieg X3 Mill

摘要

Having had a Sieg X3 Mill for a number of years the only down side was that there was not a fine quill feed so I decided to fit my own version (photo 1). You will see from photo 2 that one division equals one millimetre; the division itself is about 2 millimetres wide so there is not much chance of putting on a small cut. You could lower the head to put on a small amount of cut but I found three problems with doing that. First, over the years, when lowering the head of a machine it was normal practice to lower the head lower than that which was required and then wind it back up to take the backlash up. (I am not saying there is backlash in the head screw in the X3.) Secondly, you have to move back from the mill and bend over to operate and see the head graduation dial because it is lower than the table. Thirdly, sometimes the table can block the view of the head graduation dial.
