ABSTRACT:
A linear digital readout assembly for milling machines and the like and structure for mounting the same to the machine, comprising a preassembled, prealigned scale and reading head assembly, with the scale and reading head, respectively, carried by adjacent, relatively movable parts of the machine and operatively connected to a digital display unit to give a visual digital indication of relative movement between said movable parts of the machine, and unique mounting structure securing the scale to one of said movable parts and securing the reading head to the other of said movable parts, said mounting structure enabling said scale and reading head to be secured to the respective parts of the machine with a minimum amount of effort and in a minimum amount of time and resulting in a durable, accurate and economical digital indicator for relative movements between the parts of the machine.
