BORING
This mode is used to remove material in the longitudinal direction, but from the inside. Starting
from the zero point, the lathe tool moves to -XP, then to -ZP, where the length corresponds to
the depth of the material removed.
ATTENTION: -X is ALWAYS in the removal direction, in this case -X is towards the oper-
ator! This is the other direction as with external turning! To zero the X axis, always ap-
proach the operator and then set it to 0. This is the only way to ensure that the backlash
is taken into account.
IMPORTANT: ALWAYS MAKE SURE THAT THE ZERO POINT IS SET CORRECTLY!
Moving axes and directions:
• X towards the operator (-X)
• Z towards the chuck (-Z)
Required data:
• Feed F in mm/U
• ZP: Machining length in Z direction, must be zero or negative
Optional data
• XP: Cutting depth in X-direction, must be zero or negative.
• If XP=0, the material is only fed in the Z direction, e.g. for manual feed in the X direction.
• If XP >0, the number of cutting passes can be selected before the start of the process.
Available parameters in the parameter menu:
• X Ap Finish - depth of the last nishing pass in mm
• Finish feed rate - Speed of the nishing pass, either as a percentage of the feed rate set, or if
it continues to exceed 100%, also in discrete values in mm/revolution. The roughing pass is
then carried out at the feed rate (F) set in the cycle, the last nishing pass at the speed set
here in the parameter menu. The setting allows fast roughing with F and subsequent slow
