It's possible but highly unlikely of achieving it under normal conditions.Is that possible? .0000000001cm?
You make a lapping sleeve or rod if inner, you size it just about the same size not exactly the same size. you spread your lapping compound, and run the lathe; running the sleeve back and forth. The sleeve is softer and holds the charged lap, and laps (polishes) the thing you are lapping. Very easy, very quick. your finished piece will look like a dowel pin, or polished whatever. It will also if done right make it consistent in size if you move it back and forth like you should. Hold it in one spot and you will have a step.How do you lap on a lathe?
I have a cast iron Lapping Plate and no it can't replace the surfice grinder .Does anyone use one?
Could you lap your parts in place of a surface grinder?
Tom is using an optical flat and a single frequency light source to calibrate the lapping plates. That shows the individual wavelengths on the workpiece, and visually shows any discrepancies. Like scraping, lapping is a fascinating way of making things incredibly flat while using imprecise methods that gradually achieve highly accurate results by averaging. There is a method to the madness and a madness to the method! Humans are clever animals, sometimes...Is that possible? .0000000001cm?
