Lathe Bar feeder

[d0gFartz]

Anyone using one?.....if so whats your code look like to run it,doesnt have to be any particular make or model

Thanks

[MACHINEMASTERG]

what type of lathe are you using ????we use a bar puller its ok... from royal products

[Mike-T]

It really depends on what type of Bar feed your

talking about.

the barfeeder to cycle, You set up how far it

feeds the bar out on the barfeeder itself.

Hey dogFartz,

 

This is what I use on our mori sl200smc with a smw space saver 2000 bar feed. This cycle works flawlessly if the sensors are set correctly in the bar feed. We have the bar advance cycle at the start of the program.

We use an LNS Servo Quickload barfeed, works very nice without a stop; very repeatable. All we need in the program is:

 

M84 (chuck open)

M93 (bar push)

M83 (chuck clamp)

 

Works very nicely for us up to 3" diameter steel 48" long which is the biggest stock the machine will take.

I have a Mori SL15 and we do occasionally bar pull.

I actually make my own grabbers to pull the bar.

I use a piece of round, bore the end to the stock size for an inch or so. Then split the puller as far as necessary and it collapses slightly.

Works great.

 

I rewrote my post to allow me to input in misc integers and variables.

So, in the cutoff op say tool#5 the misc variables will call up the next tool, say tool #6 (Bar puller), and after the cutoff is done it goes to the puller and does the rest.

 

Integers:

MI9 Stock pull yes=1

MI10 Tool #

Reals:

MR8 Stock to Grab Z-

MR10 Pull Distance Z Incremental (W).

 

The post then looks at these entries and outputs the grab, chuck relase, pull, chuck tighten, and pull off.

 

Works flawlessly everytime. Unless Data entry (Me) screws up.

Hey PhilCott,

How does your machine know when you are out of stock?

[resjun]

lns servo bar feeder is good but i forgot to put a dwell time for the servo to pull back from the bar.she was a rocking

[Philcott]

Andy,

 

I have proximity switches that need to be set. When tripped (electronically) the machine will run the last part, then on the next bar feed operation, the program will go into the remnant eject sub routine to push the end piece into the chip tray. I have had this process going for a couple of years and it is flawless. The only draw back is it is a slower feeding process than some of the other methods. The advantage is continuous bar feeding. We are able to stack lots of bars at the end of the PMS (night shift) and the machine will still be happily running parts at 6:00 am when I come in.

Nice idea using your lathe to cold work the stock material... What did your jedi master think of that?

[d0gFartz]

Thanks guys for all the sample code

[resjun]

he wasn't there at the time but im sure he have it jumping down the shop floor i had to change pants after that one
