Digital readouts

Here is a low cost idea for a home milling machine. A Korean company called Rong Fu, developed several inexpensive Mill Drill machines a number of years ago. Those machines were cloned and/or sold under various brand names, but all looked and worked about the same. Today these type Mill Drill machines can be found in good used condition for under $500. Adding a lost cost digital readout (DRO) system greatly improves the productivity and accuracy of these machines. In this article I show one way of inexpensively adding DROs to a Rong Fu RF-31 rebranded Mill Drill machine. The type of DRO’s used in this article are not as accurate as systems normally used on Bridgeport style milling machines, but these DRO’s are able to work to within 1 thousandth of an inch (0.025mm) … which is a huge accuracy improvement over using just the knob dials, especially when considering the lead screw backlash and human errors that occur trying to use the knob dials. As a beginning machinist, I would never have tried to make an elaborate part without these DROs installed, they really provide a great deal of confidence.
