Contour machining, direct longitudinal – finishing
longitudinal with direct contour input unit
The unit finishes the contour defined by the parameters in one
pass. In EC you define whether you want to machine a normal or a
plunging contour.
In Machine Parameter 602322, you define whether the
control is to check the usable length of the cutting edge
during finishing. For recessing and button tools, the
length of the cutting edge is not checked.
Unit name: G890_G80_L / cycle: G890
