For the purpose of automatic longitudinal turning there are two feed rates, being at your disposal:
0,085 mm and 0,16 mm/revolution. (Upon delivery, the gears producing a feed of 0,085
mm/revolution have been put on).
Putting on different combinations of gears enables you to cut metric thread ranging from 0,4 to 3,0
mm in pitch. The same applies to inch thread ranging from 10 threads/" to 32 threads/" in pitch.
