  • Method for the multi-stage grinding of workpieces, and vacuum table, storage container, stripping device and plant for carrying out the method
    Patent number: 10081089
    Abstract: The invention relates to a method for the multi-stage grinding of workpieces (20) made of hard mineral materials using a robot (10). To this end, the workpiece (20) is moved into a processing region (21) and measured and/or oriented there by the robot (10). The robot (10) comprises a grinding head (11) by way of which it then takes up a first abrasive (14) preferably from a storage container (30) and starts a first grinding process. After the first grinding process is complete, the robot (10) releases the first abrasive (14) again and then takes up a second abrasive (14), preferably from the same or some other storage container (30). Then the robot (10) starts a second grinding process, and after the latter is complete, releases the second abrasive (14) again. One or more further grinding processes may be provided, but the grinding method can also be finished after the second grinding process.
