MY CNC BAR FEEDER 6 TO 12 FOOT BARS HIGH RPM CHECK OUT VIDEO

PATENT PENDING

Very useful and an interesting design, but unless the bar is being fed in by the unit and not pulled in by the tooling, (not apparent either way from the video) it's not a bar feeder.

I hope you plan on putting some guards around it.

What is your idea of high rpm?

[hiiesalu]

It has been run at 3500 rpm and it should do 6000 rpm with roller every 4 inches it does not vibrate, I have run this one about 1000 hours and no wear
so we plan on making these for six foot bars

Thanks you for checking the Bar Feeder

Yes to be a bar feeder it needs a pusher and that can be added with a end of bar detector and feed hold or reset circut to stop the CNC at the end of
the stock

I would not like to be near it with a 12' bar running at 6000 rpm and the BARFEEDER supported by a single bracket to the machine.

How do you accommodate different size bars?

Yes to be a bar feeder it needs a pusher and that can be added...

A 12' bar sticks out about 9' from the end of the machine and a 12' pusher is needed to push this bar full length; therefore you need somewhere around 24' past the end of the machine to fit all this in. You cannot bring the pusher in until the machine has stopped and cannot restart the machine until it has been retracted so pushing is going to be very slow.

I will agree that this is an innovative approach but having had experience with barfeeders that could handle 12' bars on manual machines and smaller feeders on CNC machines that can advance the bar with the spindle running I am dubious about the practicality and potential market size.

How do you accommodate different size bars?

That's what I was thinking. The machines I've ran all have feed tubes, for the stock material.

Do you have a complete setup for each bar diam. ?
