Rectangular spigot (CYCLE76)

Function
You can mill various rectangular spigots with the "Rectangular spigot" cycle.
You can select from the following shapes with or without a corner radius:
In addition to the required rectangular 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 by the cycle in a
central position on the finished spigot.
The spigot is machined using only one infeed. If you want to machine the spigot using
multiple infeeds, you must program the "Rectangular spigot" function several times, with a
continually decreasing finishing allowance.
Clamping the spindle
For ShopTurn, the "Clamp spindle" function can be set up by the machine manufacturer.
