Theoretically feasible thread pitch
that
The maximum thread pitch/can be attained in the individual case with the turning machine concerned depends on the maximum feedrate and on the minimum spindle speed :
max. feedrate (mm/min)
max. thread pitch (mm) =    -
min. spindle speed (r.p.m.)
Example :
The following is yielded for a turning machine with a maximum feedrate of 10 000 mm/min and a minimum spindle speed of 22 r.p.m. :
10 000
max. thread pitch
