POWER FEED (Thread cutting operations)

For thread cutting, the saddle is driven by the threads on the 

leadscrew in combination with a half nut in the apron, Figure 

3-19.

Before engaging the half nut be sure there are no 

obstacles to saddle movement, and that the power 

feed lever is in its neutral, mid-position.

The  power  feed  doesn't  stop  by  itself! 

Other  than  intervention  by  the  operator, 

there is nothing to stop (for instance) the 

saddle running into the tailstock.
