ECS G87 Boring with Retraction Cycle

ECS G87 Boring with Retraction Cycle

This cycle differs from the “Boring with Spindle Stop” G86 because in this case, when tool reaches the ENT quote, the spindle is not only stopped, but oriented in a specific position (through the M19 Function), disengaged with a movement in X and Y and finally moved in Rapid to the RAL quote.

The cycle Data Entry is activated, in MDI and Edit modes, through this keys sequence:
