It's time to present my latest find, a Köping S8C 1960. Swedish high quality heavy iron!

I've been wanting one for years but they were not made in large numbers so they are not common on the market. Because this was the most complex machine the Köping factory ever did and therefor expensive at the time, most customers bought the basic S8S model instead.
I was lucky to find this one sitting in a garage 700 km away, the price was right so i bought it without having seen or tested it. Arranged the transport from home and after a week it landed in my home workshop without drama.
The seller also found a steady rest he did't know he had in the last minute, i also got a lot of tooling with it :D
I have spent the last week cleaning and inspecting the lathe and beside the expected wear on a 53 year old lathe i've only found one damaged gear, it has 2 teeth missing ( large gear for metric threading ) luckily they can be bought new.

Here are some basic metric data.

Weight: 3400 kg
Height: 130 cm
Width: 130 cm
Lenght: 260 cm
Maximum workload 2200 kg !!!!!! :eek:
Power: 15 Kw/20 HP
Distance between centers: 1000 mm
Swing: 8 inches or 200 mm (max diameter: 430 mm over bed)
1500 Rpm

And some pictures.

Are there any places beside ebay that sells schaublin 70 accessories and parts ? I am looking for index plates and some other accessories, just wondering could there be other sites that I have missed out ? :confused:

I have a very nice Schaublin 125C. with older Heidenhain DRO. In May, the Y axis reader went south and on June 6th I shipped the scale to a forum member who previously had done a good job in repairing a Heidenhain scale for my Deckel FP1. Here I will cut a very long and sad story short. The upshot was that after begging him to respond to me via many emails and phone calls I finally heard on from him August 13th that the glass scale was broken. He will do nothing for me - other than to sell me a complete new Heidenhain system.

That is now in the past. I am able to get a service exchange unit from Germany but do not have a scale to exchange, so am looking for anyone who may have an old LS 803 scale lying around. Anything between 22 and 40 inches will do just fine. Many thanks in advance.

Specifically for the backgeared, open (for workbench mounted motor), square head machine.

In Passion-Usinage's 102N maintenance manual the procedure and drawings refer to the closed head model. The model with the motor in the base. That makes the procedure a little unclear because the part number call-outs in the text do not match the drawing, and the drawing is not quite correct for my headstock version. Part no. 105.26.000



The above drawing is for Part. no 105.27.000

The manual states that the bearings must be lubricated every five years with Kluber Isofix LDS 18 A. The lubrication procedure is given as:


So...

1) Exactly what is this oil of turpentine?
2) How does one lube the countershaft bearings? Is there a trick to non-destructively remove the pressed retainer, part no -26.078?
3) Must the M10x25 screw in the center step of the pulley cone be taken loose? For the backgeared head it is not mentioned in the documentation.
4) Are there any Gotchas with respect to trapped parts, or does the spindle just slide out the nose end once removing the end caps and the center piece (at the back side of the reduction gear housing)?

Have any members here done this procedure?

Thanx
<jbc>

I have a Harrison AA for which I'd like to acquire a taper attachment.
Long shot, I know.

I believe the M300 would be the same.

Thanks,

I put this together wrong so got around to fixing it today. When you had the long feed going it would intermittently kick the cross feed a smidgen. Irritating to say the least.

Basically planned how to do a controlled lift on carriage saddle and extract the little double ended cross feed transfer gear mounted in the saddle.

Held up apron with the old floor jack mounted wood contraption I made several years ago to remove apron.

Handy to have tee slots in saddle wings.:)

From little 'ol me. In surprisingly good condition considering how ugly it is... except for the classic drive oil leak and the unclassic non functioning drive motor. What kills me is I was running the lathe thru all the paces..spindle speeds, feeds, threading, etc in preparation for making a video of same when the damn motor ceased to turn. If it had run just one more time would have made a world of difference in folks confidence that it really does sound and run great.

I should think the tailstock alone is worth the opening bid. Certainly the tailstock and the steady rest anyway...plus a nearly pristine genuine Aloris tool post.

Hi
I'm considering buying one of these used for our shop. There isn't much info that I could find on PM. I know they are still around and seem to be common in Europe but very rare here in the US. I will get the model # and post photos soon. This seems to be a light ~17" lathe. Any known problems with these? What would be the chance of importing a used taper attachment for it?
Thanks for any info about these
Andy

]So I found a sag 12 on cl a few weeks back.I bought it without looking
at it thinking worst case I had a project for a few weeks.Showed up looking
very neglected but not beat to crap.Came with tooling, 3/4 jaw chucks , a 4 jaw scroll
and a pratt bernard collet set.I decided to strip down ,fix ,repaint.I found a crack in the
apron .This I ground out ,clamped back into shape and re-welded.Turned out better then I had anticipated.
Now it's all back together except for the micro switches in the control handle.Turned out to look not bad.
I powered it up and tested before the tear down and everything was fine but the switch.
The Graziano is a nicely designed machine.Very easy to work on .I'm a bit surprised that the apron
was cast aluminum but much easier to repair than cast iron.Closest thing for a date was on the transformer,
1985.

Hi All,

I wanted to share with you an unusual acquisition: a Weisser RO 75 turret lathe from 1957. It was made by J.G. Weisser Söhne of St. Georgen, Germany. I just picked it up at auction and although it is a bit of a monster, I think it could be a very valuable addition to my shop. The foot print is just a little bigger than a Hardinge chucker (maybe 25%) but it is definitely much beefier. The motor is a two speed 3.7/5.5 HP and the spindle speeds range from 61 to 2000 RPM. What amazes me is that hole in the spindle is 3 1/32" (77 mm) diameter. The largest of the collets I got is 3". The turret plate is about the same size as a Hardinge but the headstock is just much bigger and the power transmission is accomplished with a huge gear shift lever that switches between 4 predetermined speeds and a center spindle brake. The swing is 13" and the bed is 4' 4". It came with a full set of collets and some tooling although most of it looks shop-made. I have the literature and manual but they are rather sparse. Has anyone out there worked with one of these or seen them in operation? I have yet to clean it up but the condition looks pretty good, although it was repainted. It came from an auction in Belmont, CA, from the shop of Louie Lang. He had a wonderful collection of European tools and I would certainly appreciate it if someone could put me in touch with him. Here are some pictures and I welcome any thoughts.

Normally I wouldn't post about anything up for auction before it sells but the customer base for the below is nearly zero so I figure what the heck. The mystery is how on earth did that panel come to exist as a separate entity, now for sale ?

Good evening to you all!

I have a little problem that I haven't solved yet...
On my AI Hembrug is a handle that does not do what it's supposed to do.
Is there any body who can help me with explaining how it works??

When I push down the handle, or pull it up, nothing happens :confused:
I want to cut some inside threads in a steel bus.
It's over 30 years ago since i've done that :o so have to learn again.

The left handle is for automatic feed, the middle is for threadcutting. Correct me when i am wrong!
The problem is when the lath is turning and I push the handle down, or pull it up, nothing happens, the chisel stays at it's place.

I have pulled the whole handle out of the lathe, and I think it's a conical setting.
When you push the handle, the conical ring pushes again the inside of the sprocket and so you have a connection, at least I think that's what it should do.

Can someone explain to me what could go wrong, or what I am doing wrong?

I am talking about the handle with the black ball.



Thanks for helping!!

Best regards,

Kees

Not sure I am posting this question in the most effective place but here goes,

I just got a nice looking brute of a Takisawa gap bed lathe Model TES-8 or at least that is cast into the bed of the lathe. It looks like it was built in the 70's with the appropriate green import paint scheme but it is no light weight at around 8,000 lbs and 20 hp. It has a 30 inch four jaw chuck on it with an inch or two more capacity than that with the gap out and the steady rest that came with it has a 12 1/2 inch cenfer height so I guess it will swing about 25 inches or so with the gap back in.

It has a tag on the headstock that says it was made for CHORI Mfg. but Takisawa is cast into the bed. Anybody have any clues to help me figure out what I have here and maybe find some printed info?

All help is appreciated, thanks

Good evening.

Where to begin...well...at the beginning.

Sometime in 2012 I managed to get leads on a Weiler Condor no longer in use at the university workshop. They were willing to donate it to our museum and our chaiman was able to make the deal final. It was our machine, they were in no hurry to get rid of it. Perfect. We were doing major renovation and remodeling of our facilities, no time to mess around with machinery.

This whole ordeal was done by sping 2013 and in summer 13 our guys got the lathe and sold the old Colchester.
While that happened i was away, spending the entire spring and summer in another city, work related.

Turns out the machine looked ok from a distance but was real dirty inside and repainted several times.
Not the kind of "rustoleom repair" job, but bad enough to warrant complete stripping and rework.

We have a super motivated guy on our voluntary crew and he did a lot of work in no time. When i got back the machine was repainted, reassembled - with all non spindle bearings replaced. Almost ready to go. Terrific.


But we are still having some trouble with the spindle bearings.
Axial thrust is absorbed by axial ball bearing set to a preload. No trouble with those.
Radial force is absorbed by a big grease lubricated cylindrical roller bearing in the front. This bearing has a slight taper to the ID of the inner race, and is drawn onto a taper on the spindle. That expands the inner race and adjusts clearance.
There are two grooved nuts on the spindle. One draws the bearing tighter, one loosens it up. Both are secured via setscrews engaging small pressure pieces with a thread profile.

Our guy who did the restoration told me that he could not set play to 0 / preload because the bearing would run hot.
Allright. I was not happy with it, but i decided to wait a moment.

Soon we had the first bad workpiece on the machine. Big square block to be turned into a spare part. Lots of interrupted cut.
Next week the machine behaved like crap. Totally unusable.
I Measured spindle play as 0.0005. Bingo !
Obviously the bearing settled at the equilibrium of forces between the two nuts.

I reset at 0.0001, after a few workpieces it was back at 0.0002 and i set it again at 0.0001.
The front end of the headstock now reaches about 120°F perhaps 140°F at 2800 rpm max and machine behavior seems back to normal.

But i still dont like it. My hands are very sensitive to heat and it was a cold day. I think the 120 estimate is more likely to be the case. The spindle itself got warm too, but not that much. And it is a grease lubed spindle. No oil to carry away heat.

Conventional wisdom for tapered roller and angular contact spindles is preload. My guts tell me that this spindle should have 0 play too, it is a toolroom machine of fine make after all.
But i never read info on this weird arrangement of bearings.
This is our only non historic lathe and if we have to hog some big piece, toolroom lathe or not, it needs to hog.
In other words....i want that spindle as tight as possible without getting into thermal/mechanical trouble.

So, what do YOU think. What works for you ?

Thanks in advance.

Hi

I had the oppertunity to work for a machine trader as a organiser (clean and sort pallets after pallet of auction bought machine parts). The guy is 71yo, so he needs some help once in awhile, and I get paid in tools :willy_nilly:

However I saw that he had a schaublin 22 mill, with some tooling standing in a corner. So if anyone is interested I would gladly put you in contact with him. He does not use a computer, and do not really speak english.
I think the price was 7500euro.

PM me if you want to know more.

Simon
