Remaining Risks and Dangers
Danger
In operating mode III - universal/hand mode the axis
drives remain
connected for all axes . This is
necessary to ensure the accuracy of the machine
also during working with the quill.
This however also means, that in this mode the
operator is exposed to exeptional dangers and
needs to be trained specifically.
Because of the fact that the axis drives are
connected, special care has to be taken, that the
operator does not reach between moving machine
parts and walls.
