Happy about Bar pullers...

Very happy today...
My boss said ok to getting the bar pullers...
FINALLY!!!
He game me the ok to just buy them...
We are going to get FIRST... The barpuller that has a shank , and goes into a boaring bar tool holder... Then it has threads on the end of the shank... And you screw on to it, these little tapered tubes, that have 4 fins made from some sort of steel that springs back... Maybe spring steel... And it comes with 6 different sizes... From 2 inches, down... In .125 incraments... So we will be getting 2.000 / 1.875 / 1.750 /1.625 / 1.500 / 1.375 ... But the only problem is, if we want more sizes, like lets say we need somthing on the 1/16th like 1.8125, we have to pay 43$ per additional size we want... But anyway... its 176$ as is... with 6 sizes that i stated above... not too shaby... Also, my boss said we can take another look at the coolent powered version bar puller... If you read my other post, i said that we tries to demo it, but we didnt make enough PSI to grip the stock... But my tool holder has 2 outlets, and it always goes to the path of least resistance... So we threaded the secondary (external) hole... and screwed in a plastic bolt... Its tight and does not leak at all... I turned on the coolent and put my hand on the face of the holder, exactly where the coolent will be comming out, and into the puller... I could not keep my hand on it... The pressure was too much for my hand to hold it back... I was at a strange angle, so i did not put 100% force on it... But i must have been AT LEAST putting 15-20 pounds and could not stop it... So to pull 64 pounds of steel, we need 8 PSI... I think we will have no problem... And if it works well, My boss said we can just get both...

I was talking to him alot, and i always talk about you guys... I tell him how knowledgable you are and how helpfull you are... And i told him about Automating some things... The other CNC guys we have are all older, and they think... One guy should Cut the material on the Automatic SAW outside... Another person should Face it to final length or just leave about .010 , and basicly rough the OD if its needs it... Then they think they should get the part all nice and ready, so they can just run the program without doing any of the dirty work... I say,,, HEY !!! thats 3 people doing the job of 1... WHY WHY WHY ???

I told him if he gets the correct tools, i will just get handed the RAW STOCK!!! and i will give him a finished part... AND FASTER then anyone else in our shop... He liked that part... I also started working on him a bit, for a 4 axes lath with a nice little drill in there... and i told him i could drill and tap as well... Then his face opened up to a big smile... So now he is looking around... Anyway... You guys have givin me such great information and its been so good to learn from you... i cant wait to try some of the things i learned... i just need the TOOLS!!!

Anyway...

Just wanted to share...

No need to repley if you dont feel it...

Take care... ciao ciao

As long as your talking to your boss about us, could you put in a good word for me about a raise?

I told him if he gets the correct tools, i will just get handed the RAW STOCK!!!

you mean a mazak integrex with a subspindle, right?

PI, I have a customer thar bought a Mazak Integrex a few months back. In there all the time and gotta be there in the morning to fix another machine. Those things are amazing, pass off the part to another spindle to finish the back side, mill, drill and tap either the end or the OD. The X axis slide arangement blew my mind, 2 slides built into one to mill all cordinated together. It's set up with a Link bar feeder, they have skids of material loaded with job tickets in the way. Another customer of mine just bought a Mazak, forget the model, it's awesome, boring mill, 7 axis I think, that turns , mills and just about anything you can think of. Has a pallet changer for were the chuck mounts to turn It pallet changes chucks with parts in it. Cost about a million. It's big, had to take the biggest doorway into the shop and bust it up to get it in. 4 week setup time for the Mazak guys. I don't know that I want to play on either of those toys when they are out of warrenty. But I'm hopeing I can, I want to see what makes them tick.
Bill

Yup...they will boost your productivity. Just watch the drops, they can cause havoc. (AKA crash)

I found the fingered puller too pricey and SLOW. Went with the Royal Spring loaded puller. Adjustable fingers, in 1/8 increments and tension has some adjustment.

Yeah they are pricey, but to make one or two you don't save much if any money, by the time you make all the individual parts, fit them together its cheaper to just but it and do what we do best, make parts.

Then again if you be a tinkerer and you can waste a day or two, sure you can make it. I have to account for 70/hr, a day playing on a puller is 560.00 minimum, the puller is 450.00 plus shipping.

thanks sim...
we were thinking of the coolent powered version and the tapered push on type... not the spring version... but who knows...

To pi...
I dont know about that machine you are talking about... i was talking about something for our shop that is in the 30-40k range... Maybe a used 4 axis lathe... So i can do some drilling...
Nothing too fancy because me boss is tight on money...

But if i could face / center / pullbar / machine / drill / tap / cut off / repeat ... it would save so much time...
and money...


PS : lets say i get a long 2 inch stock and its slipping for some reason... Maybe i can just touch the part with my cutoff tool and make a small .050 deep groove, and then have the 3 fingers go in there... and then pull... maybe that will work... who knows

mazak integrex is the only thing that makes working in manufacturing worthwhile.
it is a mill/lathe that does it all. it will make your lathe look like a drill press.

You say its the only thing that makes this biz worthwhile, to you!!!
I like my machine... And believe me, if i could convince my boss to spend HugE money on a machine Ultra nice like the one you describe, i would... But there is no chance...
HEY PI!!!
one more thing...
I have seem many 4 axes lathes with drills...
But the problem is, they can not drill at angles... (at leaste not the ones i have seen...)
They can drill in different possitions by rotating the part in the chucks... But not acctually at an angle... So let me ask you... We make this one part, that needs a through hole of .500 inches... +.003 -.000 tollerance... But it needs to be chamfered on both sides, and it must be at exactly 2 degrees... once the hole is drilled , we turn the part exactly 180 degrees, and do it again... this gives us a .500 hole only at the center, with a large hole at the ends... But only larger on one axis... This is what the part needs... Can this machine of your do things like that ? I mean its no problem for our mill... But i wanted to have it as part of my lathe, but most of those drills on a lathe can not be angled... Anyway... just wondering about that, and what the cost is on one of these machines you are talking about...

thanks again

yup.

btw a 4 axis lathe can drill angles. done it many times

I like my machine

your macine is junk!!! ya hear me? JUNK!!!

Put a 2 deg shim on on of the live tools, and move it in at an angle?

yup. or just get an angled live head

i have never seen an angles live tool...
is this a lathe ? like if we buy one, can i just say, we want a 4 axis lathe that does angled drilling ? or are you talking about a modification ?

Also, i dont like the idea of shims... Seems really cheesey... even though it may work perfectly... I would rather have a live drilling tool that i can program for 2 degrees... or are we talking about setting it up at 2 degrees and doing the work, then having to put it back ? because i would love for it to be programmable...

thanks you guys are very helpfull

PS : to pi... Hey man, my machine kicks ass... I love it... I even gave it a name... chucky the lathe!!!

hahaha

just kidding

And the bar feeder's going to be Bride of Chucky?

Sorry, couldn't resist...

A conventional lathe does not have programmable live tooling angles - actually, I've never seen a machine that does (although given my limited experience, I'm sure somebody else has).

hey thanks hammer...
so its not programmable...
so how is it set ?
it just pivots, and there are some numbers to show what angle its at, and when its all setup , you just turn a screw or something to lock it in place ? is it that simple ?

thanks again

Depending on how bling bling your lathe is you can drill and or mill +/- 60 degrees . We were looking at a Puma, until we heard about dae-boo-hoo service.

Ahh - HA! See, I told you somebody else here would know about ones that do!

damonfg - Which, besides the Daewoo, do you know of that do?

I believe Mazak does but I didn't get a lot of help on their website.

And here's the most incredibly jaw dropping tool porn I've seen in a while:
You just have to go through the whole site. Absolutely amazing. It's like a 5-axis VMC crossed with an amazing lathe.

I refuse to see one of these in person. May just have to drag it home.

(note the oil holes!)

I love it... I even gave it a name... chucky the lathe

does chucky have a nice long boring tool?


angled tool holders are made by several aftermarket tool companies. usually companies that make speeder heads also make lathes live heads.
some are adjustable for any angle. i did lotsa angled drilling/tapping on mazak multiplexes. i made an excel spreadsheet to calculate all of the peck/approach/depth points. very handy.
