The protractor is machined with most possible precision. All machining steps of the ground plate and the guideway of the bar were performed in one set up on the CNC machine. This one set up process avoids any error caused by machine fixtures We first mount the black block on the base plate and then the spindle hole is drilled, the guideway for the bar, the reticule and it’s grid of lines are machined. During this process only the tools of the CNC machine are changed but the protractor is not taken from the machine until all is done. This results in a precision of better that a 0.01 mm.
