Hi all,
i was once again surfin' craigslist and found my newest addition to the arsenal
i'm into old and odd stuff, this one takes the cake!!!
she's going to need some work done to her. maybe a little(lot) more than a coat of paint and a clean up.
sometimes i'm too stupid or proud to back down

May i introduce you to Joy, my first universal milling machine.
She was manufactured in France for the USA market.
she's seen better days, looks like she got into a fight with an ugly stick and possibly got the ugly stick broken on her.
she doesn't feel sloppy but as all the equipment i seem to find , it needs a good cleaning. we'll start there....
her's a few pix for the interested

133.jpg
129.jpg

the mill has a vertical milling head as well as horizontal milling machine features.

the vertical and horizontal spindles are NMTB40 taper. the machine came with a pile of tool holders but no cutters.
the owner also threw in a static converter he wasn't sure how to hook up.
the machine came out working claimed the second owner, but it is a three phase machine
and was never run by the second owner.

131.jpg

this mill has a universal table that can be skewed 60* from center axis (30*+ and 30* - from 90*)

134.jpg

it has rapid traverse functions on the vertical and crossfeed axes.

she is still at her old home, i'm planning to pick her up next week.
until then i'm doing research and collecting literature on the old girl.

one source that already has been helpful is a French Machinist Forum

http://www.usinages.com/forum.html

i was able to download manual/ parts book after registering .

(Thanks Phil 916 for the information and link!!!!!)


thanks for looking and reading,
any resources or hints would be greatly appreciated

U Sir, Suck. I'm green with envy. I need one that comes with the skill to utilize all of it's capability. Have fun with it.:))

thanks:))

i'll be spending a considerable amount of time translating French to English to read and understand the basic manual i was able to get.
perhaps a few of the functions i may never use for practical purposes but one never knows what the future may bring.

i believe it is better to have capability rather than wishing i had the capability.

thanks guys for reading!!!

ho damn, that's an impressive machine! I'd definitely need to read a manual before trying out all those handles and levers :) Looks like it just needs a good clean and oil and it'll be good to go..

Thanks Tool-in the-box and mattthemuppet!!!

i haven't had a French class ever, i'm trying to learn French nomenclature on some old scanned images from a manual.
the manual was in pretty good shape but a little pixelazation occurred when printing out from the pdf file.
it's clear enough to read in most instances but some of the drawings aren't so good.
the manual looks like it was done by hand with the exception of a few stamps.
it's not what i would call a good manual , it lacks a lot of technical information.
but on the plus side the mechanical drawings are sufficient and detailed. they appear to be a copy of the draftsmen's work and show just about everything from the cut away view.

unfortunately, Joy is going to need a little more than cleaning.
there are some bearings that need to be replaced, i know this already.

i'll break my machine down and detail the operations i perform for those interested.

thanks to all for reading and commenting!!!

I think the AM/FM cassette player is a very unique option for a milling machine...

That Dufour follows the design lines of the Schaublin SV52:

http://www.lathes.co.uk/schaublinmiller/page6.html

I think you have scored a gem there.

Paul.

Thank you Paul!!!!




i have a worm gear that transmits power indirectly from the traversing motor that has seen better days.
it's not broken yet but it's pretty dang thin.
a couple pictures.



worm gear 1.jpg
the steel gear (above) is still serviceable, the bronze gear, well... not so serviceable.

worm gear 2.jpg
worm gear 3.jpg

i'm open to parts sources or other means of getting this gear replaced
thanks in advance for the help!!!

Have you tried Boston Gear? No personal experience with them, but a shop teacher suggested them for a metal version of the broken plastic gear that went on my previously owned Grizzly mill. I've heard their name bandied about a bit, too.

Nice find. Which list were you surfing and where'd you have to go to get it?

Thanks Ryan for the suggestion of going to boston gear, i'll do some research...

on Craigslist, i usually type in the name of the piece of machinery spelled correctly and then i check for misspelled machinery as well
you'd be surprised how many interesting things i find misspelled or mislabeled.
I check all but the most remote california listings.
I got the mill from a guy who lives in Daly City.
i can't wait to bring her home but i'll have to wait until next week for that...

That appears to be a double lead screw, making the worm gear a tad trickier to hob. The helix angle is steeper. If Boston can't help, look at Martin. If not them, let me know. I have some other sources.

Wow - what a great looking machine! Looking forward to seeing it develop.

I'm realising that I have met another milling machine obssessive!

Wish they fell into my lap like they do yours :)) .

Cheers,

Hi Daryl,
Thank you, she is just great isn't she!!!
Yes she had made some test cuts on some aluminum and steel.
the traversing gear system has been removed from the mill, so all table and knee movements are manual for the time being. i have an oil leak at the drive gear for the collapse-able driveshaft that drives the table feeds.
luckily the seals and bearings are standard metric and easily obtainable.
i have the replacement seal, but have not got into the project yet.
it's gonna be messy and i would like to devote more than an hour at a time to make things right.
kinda the story of my life, too many projects- not enough free time for the near future.

i'll be sure to post pictures of future operations
thanks for reading and commenting!!!

Great looking machine. :thumbzup3:

Do you plan to get it up & running or do a full frame up restoration?

Hi Mark,
thank you,
from my initial observations, i'm leaning towards putting her back to work for the time being.
i have run her for testing purposes and have not heard cause for alarm.
if accuracy or necessity dictates a full scrape job, then so be it.
if i have my choice, i'll get to have some fun playing with it before i rip it all apart.
if she can get a couple paying jobs to offset the costs before teardown, that would be great!!!

I also know a bit of French. Not fluent, but I get by. Technical French is doubly tricky, but am always willing to try (and I know a few people who are way better than I am).

Google translate might also be helpful...?

Cheers,

gary

Hi Gary,
i know your meaning with "Technical French", google translate has left a lot to be desired.
luckily, a couple members of the French Machine Forum- Usinages have been very helpful in translating colloquial greetings and phrases for me when google gives me a strange translation that i know is wrong for the context of the phrase.
It's challenging, but anything worth doing usually doesn't come easy for me :lmao:
thanks Gary!!

Hi Brian,
thanks for posting the pictures!
she's prettier than Joy,:drool:

i may hit you up to make a tracing of the O/A support, or maybe some dimensions.
i may need to make one, i'm not having luck finding parts for the old girl.

I'm going to need to learn more about these.
How often have you used the Universal feature?

I use it on a fairly regular basis. It is more rigid than my Bridgeport, plus it has power feed on all axis. I just need to do a little work on it. I have some oil leaks that are annoying. It is on my list to restore next winter.

Hello, my name is Brian and I'm a toolaholic

I just traded for one of these, dufour 51 with the high speed head. Don't have the horizontal attachments and I can't really find info on the high speed head.

hi fuzzywayne,
nice score on the Dufour!
welcome to the (small) club!
parts and info are like hen's teeth, but i have a little info on them.
if you email me at ulmadoc@gmail.com i can provide you with a PDF of the manual i was able to download.
the manual is in French, it is detailed and the parts exploded views are very accurate as well.
i hope it may be of service to you.
