I am looking into buying a Haas SL 20 and i am debating puller and feeder
I have roughly ten thousand 1" aluminum turned parts to make any insight
into this would be appreciated

It can be a wash but there are some differences:

A feeder can be faster than a puller but not by a great amount unless it can feed with the spindle running so you eliminate the time spent stopping and starting the spindle.

With a magazine feeder you do not have to spend time loading bars.

I have a question:

Why SL20 when the part is from 1" bar stock, why not SL10? Costs less and has a higher spindle speed.

I would like to add another difference. I am using a puller right now because I need to move another machine to get the feeder set up. With the puller I am limited to what fits inside the spindle, about 3 1/2 to 4 feet. Once the feeder is set up I can feed a 12 foot bar. That equals less handling and less scrap.

Ok that seems like good advise, my shop is geared twords prototyping and development, but this job would more than pay for half of the machine in one shot so I can't really say no.

I do have limited space and as much as I would love to have the bar feeder it sounds like I could get by with a puller for this time.

Do you have any thoughts on years I have heard that some of the older lathes have had turret problems ?

Thanks

I would say bar feed all the way.
i leave my machine running over night on simple jobs and without bar feed you couldnt do this.
Come in in the morning and its still machining

so simple answer to me

done this for last few years with no problems

Bar feed all the way.

this way you can run the machine all night with nobody there.
money for nothing

i do it all the time with no probs

this would soon pay for your bar feed and lots more

i decided to go with bar feed and never looked back

its a no brainer tbh
for me anyway

I have a barfeed on the 10. It is good to get it set and load up the bars and go. I do not use lights out since we have not had a long run job with smaller parts to do in some time. Plus we often do not have large runs on a monthly or by weekly basis just don't have them. We usually have a average of 12-14 parts per run. When I have more I use the barfeed or puller. The barfeeder (it could be just me) does not do well with smaller diameter material and even small material like 3/16 diameter. I use a barpuller on that. Plus a barpuller can take up space for a few jobs where I might just need that extra space for a tool though rarely. We have regretted not putting the bar feed on our 20 though on occasion. The barfeed does take up a lot of space though in a crowded shop.

Has anyone tried one of these?

A friend of mine just purchased one of these for his new HAAS GT10 Lathe.

It looks well made and is adjustable for different sized bars and combines 2 tools in one to save you one tool location on your turret.

It looks cool. I do tend to part off as close to the chuck or collet as possible and I think the puller would probably space me out a little. That is a smart concept and I could still use Iscar for partoffs.

I haven't actually seen the tool in action. My friend has it working and as soon as he gets everything sorted out he will invite me down for a little demo.

I will let you know how the demo goes.
