T The B axis
The B axis makes it possible to drill, bore and mill in oblique planes.
To make programming easy, the coordinate system is tilted in such a
way that you can define the drilling patterns and milling contours in the
YZ plane. The actual drilling or milling operation is then performed in
the tilted plane.
During work on the tilted plane, the tool is perpendicular to the plane.
The tilting angle of the B axis and the angle of the tilted plane are
identical.
Another advantage of the B axis is the flexible use of tools during
turning operations. By tilting the B axis and rotating the tool you can
bring it into positions that enable you to use one and the same tool to
machine in the longitudinal and transverse (or radial and axial)
directions on the main and opposing spindles.
In this way, you need fewer tools and fewer tool changes.
The CNC PILOT supports part program creation with the B axis in
DIN PLUS.
The graphical simulation shows the machining operation in a tilted
working plane in the familiar lathe and front windows, as well as in the
“side view (YZ).”
User's Manual for the B and Y axes
The manual and automatic control functions a well as the
programming and testing of NC programs for the B and Y
axes are described in a separate User's Manual. Please
contact HEIDENHAIN if you require a copy of this User's
Manual.
