Re: Is 1/2 HP really enough?


 

Cuts like that are for roughing materials for production work. If you're doing production work it's good to have that capability. Maybe even if you're not doing production work, if your shop time is very limited. :) But that isn't appropriate for fine work. So you should set your depth of cut for the kind of work you need. As they say, it's harder to put material back on than it is to take it off. Only you can determine what's appropriate if you're in your own shop...

I have never done production, so my needs are going to be different from those of a guy who is doing production. And I piddle around trying to get the very best accuracy I can manage. Someday maybe I'll be good enough at it to take my ability for granted. Today ain't that day, though! My Heavy 10L is vintage 1941, and was shipped from the factory to a government armory toolroom with a 3/4hp single phase motor. I expect they wanted excellent accuracy and best productivity...

According to How To Run A Lathe, the maximum depth of cut of a SB9 is .125" in hot rolled carbon steel. the SB13 is .250", and the SB16 is .375".

I have never tried those depths on either my 9 or 13. ?
