Подробно Product descriptions

Machine tool probe PO series applies 3-point trigger design which is the most stable structure. There is a trigger unit inside the probe. When the stylus is moved radially or axially by external force, the trigger unit is triggered. Then the circuit inside of probe sends a triggering signal to the receiver, and the receiver transmits it to the machine tool, consequently the present coordinates of each axis of the machine tool are recorded automatically. Finally measurement results are calculated according to the coordinate records of related points.
