Hi
I have a question regarding production rates in units threads per minute for thread rolling. NO cutting, only thread rolling!
For unknown reasons, I am a bit sceptical if the following numbers are approximately correct and I would like to ask if anyone can take a look at them and let me know if they are approximately correct or not. Also I have some questions near few numbers for production rates:
Movements of cylindrical die:
RADIAL:
90 threads per minute <----- but for which diameter of workpiece (mark *
for the same questions belows)
AXIAL:
between 20 and 280 threads per minute <----- *
between 20 and 450 threads per minute <----- *
between 25 and 300 threads per minute <----- *
TANGENCIAL:
??, please someone add the data (included time interval & *)
PLANETARY:
between 450 and 2000 threads per minute <----- *
between 250 and 1200 threads per minute <----- *
between 100 and 400 threads per minute <----- *
INTERNAL THREAD:
between 50 and 1000 threads per ??? <----- per what? minutes? + *
Another short question: Is the data that FLAT (!!) die can do thread rolling approximately 10000 to 36000 per hour (workpieces with diameter up to 9,4mm) and 3000 to 12000 per hour (workpieces with diameter between 9,5mm to 13mm) correct?
I think it would be the the fastest if someone just quote and edits my text. Thank you...
