Dla unie¬ ruchomienia tulei 25 za pomoca sruby 52 ustawiamy 20 podzialke pierscienia 27 na „zero". Nastepnie zwal¬ niajac zacisk tulei 25 obracamy ja o kat 90° wraz z narzedziem. Wtedy plaszczyzna podstawowa „Pr" wiertla jest równolegla do plaszczyzny pola widze¬ nia. Po ustawieniu ostrosci obrazu mozna za pomo- 25 ca krzyza pomiarowego zmierzyc kat x dla Obu kra¬ wedzi skrawajacych ostrze wiertla. PL PLTo immobilize the sleeve 25 by means of the screw 52, set the scale of the ring 27 to "zero". Then, by releasing the clamp of the sleeve 25, rotate it through the angle of 90 ° together with the tool. Then the base plane "Pr" of the drill is parallel to the field plane I see ¬nia. After the image has been focused, the angle x can be measured with the help of the crosshair for both cutting edges of the drill bit. PL PL
