i own a machine shop that primarily does turning work. we are getting more and more order in the 2000 pcs range. parts are about 1 5/8 and smaller for the most part. i would really like to learn about screw machines, why they are faster, what are the benefits, what are the draw backs.

also i found a hardinge made screw machine and they don't seem to be very popular compared to citizens or tsugamis, any particular reason?
