Boring (CYCLE86)

Function
With the "Boring" cycle, the tool approaches the programmed position in rapid traverse,
allowing for the retraction plane and safety clearance. It is then inserted into the workpiece at
the feedrate programmed under F until it reaches the programmed depth (Z1). There is an
oriented spindle stop with the SPOS command. After the dwell time has elapsed, the tool is
retracted either with or without lift of the tool.
Note
If, for example, swiveling of mirroring has been performed with CYCLE800 before machining,
the SPOS command must be adapted so that the spindle position acts synchronously with
DX and DY.
Clamping the spindle
For ShopTurn, the "Clamp spindle" function can be set up by the machine manufacturer.
