Hi Everyone!
I've had a PM-1030 lathe that I've been very happy with but outgrown. I've had an order in with Matt for a Taiwan-built PM-1440TS thinking I would add a VFD to the 3 hp 3 phase spindle motor and change the controls to match the pre-VFD, etc. On the PM-1440TV model the lathe is supplied with a larger motor, 5 hp, and a Yaskawa V1000 VFD that will allow me to run the lathe on single phase. The fully gear head model has 12 speeds down to 50 rpm and the TV model has 2 geared ranges with the VFD supplying the speed ranges otherwise. I believe the speed ranges are 36-360 rpm and 220-2200 rpm. My question is, will I notice at lower speeds a distinct difference between the fully gear head lathe and the gear plus VFD model? Less gears usually translate to a smoother finish and less noise. Five hp would seem to be more than sufficient for a 14 inch lathe. It would be easier not to have to add the VFD and change all the control circuits. Any opinions (especially from Ray C!).
Thanks.
