TSUGAMI SCREW MACHINE

[junior33]

running a "nut" 3/8 hex aluminum(T6 6061), 5-40 thread .310 turn dia, oal is .375, simple part, cycle time is 17 seconds, I want to increase the cycle time, these parts feed another operation and the screw machine isnt keeping up.

any formulas i can use to efficiently calculate feeds/speeds, specially for the threads? any tips......thankyou everyone(advance appreciation)

In order to DECREASE you cycle time (make parts faster) you can only really play with the RPM. The feed rates are calculated into the design of your cams. If you can't keep up with demand would it be possible to add a second machine?

I wish Neal, a second machine would be nice...no cams, CNC, and yes, DECREASE......thx

I work in a shop with six Tsugamis. Generally these machines are not run wide open. (Hmm). If you are using G97 first increase your RPMs by say 10%. Then increase your feeds a corresponding amount. (If your machine is programmed and running in G96 then you don't need to increase your feeds as they will automatically increase, but G96 risks your spindle motor. G97 and G96 constant surface feedrate require some sophistication and experience in programming.
