Circular spigot (CYCLE77)

Function
You can mill various circular spigots with the "Circular spigot" function.
In addition to the required circular spigot, you must also define a blank spigot, i.e. the outer
limits of the material. The tool moves at rapid traverse outside this area. The blank spigot must
not overlap adjacent blank spigots and is automatically placed on the finished spigot in a
centered position.
The circular spigot is machined using only one infeed. If you want to machine the spigot using
multiple infeeds, you must program the "Circular spigot" function several times with a reducing
finishing allowance.
Clamping the spindle
For ShopTurn, the "Clamp spindle" function can be set up by the machine manufacturer.
