Working with a B axis (only 840D sl)
With an additional B axis, you have the option of aligning milling machines and lathes.
The initial setting in which all tools must be measured is B=0.
When turning, you can align the tool for special machining operations using the B axis and C
axis of the tool spindle.
When milling, you can swivel the workpiece using the B and C axis of the main or
counterspindle so that you can mill and drill on inclined surfaces.
The B axis is also used for aligning tools for face and peripheral surface machining.
