KOORDINATIONSMESSMASCHINE MIT VERTIKALEM FEINVORSCHUB UND ARRETIERUNGSMECHANISMUS.

摘要

A coordinate measuring machine having a vertically movable probe shaft in which a vertical fine feed and lock mechanism for the probe shaft is provided by a first knob coupled to a magnet movable between two positions, one of said positions operatively coupling a second knob to the probe shaft for driving said probe shaft in a vertical direction, the other of said positions being ineffective for moving the fine feed mechanism. The fine feed is accomplished through the rotation of a second knob which is in frictional engagement through a driven quasi "V" shaped flanged wheel with the probe shaft to be moved vertically.
