Components of the Tool Monitoring System BK MIKRO

The complete 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
• Inspecting workpieces: feeding / ejection / position / alignment
• Checking shapes: drilling depths / cavities / profile / tolerance

The Scanner

BK MIKRO® offers several types of scanners adapted to different performance classes. Selector switches fulfil orthogonal moving functions (single- or bi-directional) or perform the axial scanning of tool tips. For stroke movements linear scanners are used. Scanning wands are available in different lengths and types.

Features:

• Absolutely resistant to coolants and chips.
• Extremely rugged construction with very strong scanner shaft.
• Easy assembly and access for maintenance work.
• Wand exchange without effort, no adjustment aids required.

The Control Unit

There is basically one control unit for all applications. In order to perfectly adapt the control units to the different uses, diversifications have been realized which only differ in terms of functional range and interface characteristics. The “Basic” model is designed for simple, low-cost solutions with just one monitoring function. The “Premium” version can monitor a number of objects, and by using the optional PROFIBUS-networking complete tool inspection can be directly administered by the CNC-software. In addition, an I/O extension module allows for other configuration options.

Features:

• 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.
