How to fit DRO to a lathe

Following on from the milling machine DRO images, if you’re looking for pointers for how to mount your glass optical digital readout scales to your lathe, here are some example images of where we’ve fitted them on this WM 250V. Also shown in these examples is a WM 290V.

And here’s another example of that same axis with the splash guard refitted – here on a WM 290V lathe. Note on this lathe there’s a milling attachment in place; the narrow section design of the scales means with that even with the milling column mounted, movement is still unrestricted.

Finally, there is the mounting of the counter. Positioning of this is less critical than the scales, so you are free to locate it wherever is most convenient. We’ve gone with the headstock end as it makes the most sense for readability, shown in this example on a WM 250. Supplied general purpose fitment bracket is intended for modification depending on your specific application.

DRO manual
Warco DRO systems come with the above installation manual, illustrated throughout with step by steps. 

With any luck, with the manual to hand alongside these example images, you should be well equipped for completing the satisfying job of your own installation. Anything we missed, or something you’re still not sure about? Let us know in the comments below!

  1. is the 100mm optical scale ( recommended ) for the 250v lathe crosslide the correct size ??

  2. Hello
    I’m looking to fit a DRO to my WM-180 and was interested in these pictures. How ever this set up seem to be able to indicate the location of the tool tip in the Y-axis but only the location of the saddle in the X-axis. Is there a way to show the position of the tool tip in the X-axis?
