How the BK MIKRO System Works

Uni- and bidirectional Scanning

Depending on the preset parameters in the control unit when a start signal is given from the machine control the wand rotates left or right until it reaches the test object. In this process it first approaches the monitoring range with maximum speed, then decelerates and scans the tool with the set intensity. Once the wand contacts the tool or goes past the point where the tool should be the wand returns to home  position at maximum speed and outputs either and OK or KO signal.

By means of a preset angle the wand can be assigned a freely definable home position between two objects to be monitored. After the wand has reached this position the two objects can be charged and then be scanned. The order of the scanning direction is also selectable.

Monitoring of Scanning Range

BK MIKRO is also designed for cost-effective monitoring of objects or free space, e.g. ejection of workpieces, loading and unloading.

The desired scanning range can be freely selected in steps of 22.5° by two setting switches (W1, W2).

• Object: Changing scanning points can be monitored in a defined zone without intermediate teach-in cycles.
• Free space: The W2 angle determines the point of return, which the wand must reach in the correct process flow. An error message is displayed if the wand stops before reaching this position.

Checking Shapes

BK MIKRO9 is also suitable for checking shapes and forms of workpieces or tools. e.g.

• boreholes (TK9LIN)
• shapes (pipes, profiles, edges)

Teach-in

During the learning cycle the wand rotates until it contacts an object. The angle measured is then stored in the tool data base under the selected tool number. The preset angle for the actual scanning is then defined by the stored position considering the preset tolerance value.
