FIELD: the invention refers to measuring technique particularly for measuring of the width and the deviation of a location of a veener groove relatively to the axis of an opening.
SUBSTANCE: the arrangement has a body with two centering fingers, a veener groove, installed in the body with possibility of forward movement and back-and-turning motions around its longitudinal axis, a measuring probe firmly fixed on the rod, a measuring unit installed on the body with possibility of interacting of its measuring tip with a key groove. At that centering fingers are fulfilled and located with possibility of centering along its working surfaces of the lateral surface of a measuring probe fulfilled ball-shaped. As for the veener groove it is located with possibility of forward movement in the direction of the parallel line connecting centers of transverse sections of the centering fingers.
EFFECT: increases accuracy, productivity and simplification of measuring.
