Making some shafts today out of C1144 Stressproof Steel in our 2014 Haas ST20 Cnc Lathe.
Small diameter is .312" +/-.00025", next is .3745" +/-.0005", then 1.00" +.0002"/-.0003".
Bar stock size is 2.250" Dia. x 6.5" lg.
With the thermal compensating ballscrews in this machine, it is a virtually, "set it and forget it" operation.
Love this ST20!
