Helical milling – gear trains | john f's workshop

If the gearing between the leadscrew and the drive to the dividing head is 1:1 then one turn of the lead screw will move the table by 5mm and 40 turns will move it by 200mm – the lead is 200mm. The workpiece will have turned once. In this situation we still need two gears, one on the leadscrew and one on the drive into the driving head.
