What is the difference between a CNC mill and a CNC lathe?
A lathe usually only has 2 axis control, lathes are normally used to machine cylindrical parts, the workpiece is held in a chuck which is rotating, the tool is moved left/right (Y Axis) and towards/away from the workpiece (X Axis) , some lathes also have a revolver head with multiple tools. A mill has 3 axis sometimes 4 or 5 axis controls, in a mill the tool is rotating while the workpiecev is clamped on a table, the table can be moved left/right (Y) forward/reverse (X) and usually up/down (Z) a rotating or index table usually can be used as a 4th axis, mills also sometimes have Automatic tool changers !
