Processing device

A processing device comprising:

• a first positioning device and a processing head,
• the processing head comprising a processing unit designed as at least a tool or applicator unit, and a second positioning device,
• wherein the processing device is configured to selectively be operated in either a first state or a second state,
• wherein, in the first state, the first positioning device is configured to move the processing head in order to position the processing unit with a first accuracy at a specified processing position,
• wherein the processing device is configured to position, in the first state, the processing unit at the specified processing position with a second accuracy using the second positioning device, the second accuracy being higher than the first accuracy, so that the lower accuracy of the first positioning device is compensated for by the positioning with the second positioning device,
• wherein the processing head is removable from the first positioning device in the second state, and the processing head is configured as a hand-guided processing device, so that, in the second state, the processing head is manually positionable at the specified processing position, and the processing head is configured to position, in the second state, the processing unit with the second accuracy at the specified processing position using the second positioning device, so that a lower accuracy of the manual positioning is compensated for by the positioning with the second positioning device.
