Tool charge measurement

Furnishings in CNC-machining centres, to avoid mistakes during the feeding of the Werkzeugwechslers and to match the length of the tools with the internal data base.

mode of operation

The tool length measurement can be deployed for the tool in combined with a separate pick-up place. The operator doesn´t feed the tool changer directly, but puts a new tool on its place to take over. From this point the machine takes over and proceeds to a sensor before it gets changed into a tool changer. Here the length of the tool will be measured and compared to the measurements deposited at the tool database. With small differences, e.g. after the sharpening, only the appropriate value of the database can be corrected.In case of accidentally loading a wrong tool, the machine recognizes the mistake through the different measurements. See also: Weeke tool length control.

The tool changer will never be fed with a simpler version. For the measurement, the appropriate tool will be set up in the working spindle which goes to the sensor with the tool for the measurements.

The tool length measurement can prevent damage of the machine table or the working spindle by wrong feeding of the tool changer, e.g. with a longer tool. A refreshing of the tool database with small changes, e.g. after sharpening, is simple to execute as well.
