BK MIKRO system includes • A scanner • A control unit (with I/O extension module as option) • A connection cable The wand of the scanner inspects object positions or ranges potential-free according to the machine cycle. A micro-computer based control unit triggers the wand movement by an external signal or a signal from the PROFIBUS-Master (PLC). The scanning result is then compared to the nominal value in the control unit (by means of “teach-in” or programmed parameters) and passed on as “o.k.” or “k.o.” message via relay contacts (digital I/O) or via PROFIBUS to the machine control. Any deviation can trigger an instantaneous machine stop ensuring that the machine doesn‘t crash and also prevents bad parts from being manufactured. From simple tool breakage monitoring in a single head machine to the control of a wide range of different tool lengths in the magazine of a machining center (including their correct storage) to the inspection of profiles with the highest scanning precision, BK MIKRO® offers all functions for checking production processes: • Tool monitoring: breakage / presence / holding / detection • • All functions controlled by a one-chip microcomputer. • O.K. or K.O. indication by LEDs enabling direct control of the test station. • Intensity of wand is adjustable e.g. for sensitive drills with small diameters. • Easy mounting of insulating material housing on profile rails according to DIN. • USB, PROFIBUS as option.
