DRO - Digital ReadOuts on a Mini-lathe
What's the point?
DRO stands for Digital Read Out. In terms of mini-lathes and micro-mills, this means having a digital display of the displacement of one or more of the directional axis.
The usual cheap way of implementing DRO (digital read-outs) on a mini-lathe or micromill is to butcher a digital vernier caliper, and use the digital unit. This unit is then attached to the lathe so that the reading changes as you, for example, move the cross slide.
In my mind, DRO on a mini-lathe is about as useful as a digital RPM indicator on a mini-lathe. Utterly useless.
MY reasons behind this statement?
In summary, if you want to fit DRO to you mini-lathe or micro-mill then go ahead, but I don't think you will find them very useful.
If you are debating whether you should pay extra for having digital RPM and DRO fitted to your new mini-lathe then DON'T BOTHER - waste of money. Spend the money on something more useful.
