If you work with milling machines or lathes, this TOAUTO 3-axis digital readout is about to make your life so much easier! The LCD screen gives you crystal-clear readings with 5um resolution (that's 0.005mm or 0.0002 inches for super precise work). It works with a wide voltage range from AC86V to 240V and comes with a US plug, so no special electrical setup needed. The display is seriously feature-packed - you get reset functions, preset data input, MM/inch switching, absolute/relative/user coordinate systems, automatic division by 2, screen saver, power-down memory, mechanical zero setting, non-linear and linear compensation, and a bunch of machining functions like circumferential holes, linear holes, smooth arcs, and bevel machining. The large display is easy to read from a distance, which is super handy when you're moving around your workspace. Just to be clear - this listing is for the DRO display unit only with mounting arm and screws, not including the linear scales. You'll need to get those separately based on your machine's requirements. Whether you're working on Bridgeport-style knee milling machines or various lathes, this DRO eliminates guesswork and measuring mistakes, saving you time and improving accuracy on every project. It's one of those upgrades that makes you wonder how you ever managed without digital readouts once you start using them!
