Anybody Ever Run an Oerlikon Engine Lathe?

A DA-U Oerlikon lathe is for sale on ebay, or maybe not for sale due to the price. Have any of you run one of these beauties?


Despite the outrageous price, it is a very interesting lathe. The seller doesn't appear to know much about it. Probably missing the now likely unobtainable operator's manual.

From this site it looks to be 20" swing x 60" about 8000# and 20HP.


The condition appears very good and the very nice paint job looks original. The bed is massive with integral chip tray and full length base. It must be geared head, not VS, but the headstock is curiously tiny, very thin. Not at all what you'd expect for a 20HP geared head lathe.

The carriage has some great features, some unusual.

Nice turret stop on longitudinal and transverse motion. Maybe both kick the feed out automatically? The cross feed stop sure looks complicated enough to do so. Zoom in and you can really see the nice paint job. The capstan handwheel on the right must be to select multiples of feed rate. I don't like the round handwheel handles. Lots of Euro lathes have funny handles. The low lever under the carriage handwheel is the manual lube for the carriage. The joystick is a welcome touch when you stand in front of the thing all day.

Here you can see the unusual compound rest, which incorporates a fixed slide at 90 degree to the normal compound slide. From another video some of these lathes had this 90* slide powered for cutting tapers. I'll post a link to that vid at the end. Is the compund t-nut groove in the cross slide open? If it is talk about a chip magnet! The scales for macro positioning on cross and compound feeds are nice touches for the pre-DRO age. The tool post looks pretty stout. What is the knurled knob at 5:30 in the second pic for?

Is the tailstock air over hydraulic? There is an air connection, pressure gauge, and a control lever at the left end that looks to be a pressure control. In this pic you can also see a bellowed stud coming out the right side of the carriage. I think this may hook to the tailstock to drag along and maybe even power feed drill a la Cazeneuve. The tailstock quill looks small for a 20" lathe.

Looks like inch, metric, DP, and Module pitches. No directly selectable 11.5, 13.5, or 27 pitches. I've seen this on other euro lathes, it's not uncommon, but it seems silly on a lathe with so many added features. I don't see any threading dial. How did threading work? I think it has leadscrew reverse so maybe engage half nuts once and use LSR thereafter with never a threading dial? That is great but might be inconvenient for some stuff.

Here is a video of maybe an earlier model, illustrating some of the features.


Imagine what a machine like this would cost new today. You can get this beauty for only 45K! I'll bet they will throw in shipping too if you ask nicely.

Price is very very high, like everything else from the seller.

Wonder if the X-Y table on the cross-slide is original or added on later, because that is a Fehlmann table. I would have expected a compount rest.

It may be original. The lathe in the video has the same thing but power feed. It seems to me the manual one might be in the way as often as not.
 
German machine or Swiss? Good stuff either way. I ran a Weipert with a similar compound setup. It had a power feed on the compound slide for cutting tapers, very handy.

It does look very like the Fehlmann tables. Good catch. Maybe that is why the cross slide t nut swivel groove is exposed. It would be handy for widening threads.

It's a swiss machine. I wish Tony had something about this lathe, but the only oerlikon machine on lathes.co.uk is an interesting drilling machine.
 
The thread about "Pictures of Huge Machinery" has a bunch of pictures from the Oerlikon factory from the 1930s&40s



Not that it has much to do with that Ebay posting.
 
My dad used an eirlikon anti aircraft gun during the war, he said it was Swedish or Norse in origin, gave Germans a bad day if you hit them he said, they also made lathes drills and my preferred welding rods, SSAB seem to own them or the other way round ( hardox 600 anyone)
The lathes are good, a fair bit like a Mauser ( also into weapons)

In which branch of the service did your dad serve?

This is from wikipedia. A battery of Oerlikon 20mm cannons on carrier USS Hornet. At somewhere around 300 rounds per minute they could lay down a curtain of lead.

But apparently not enough to stop large aircraft and Kamakaze attacks. It was superseded by Bofors 40mm and a 3" gun in the Pacific theater.

Wotol (used machine website) has the same model, and it has a compound. The Fehlmann looks out of place because an x-y table is not typically found on engine lathes, which is why I suspected it was added on later.

Yes it is out of the ordinary. I agree with you it's not original. I couldn't open the picture in your link but I found other DA-U lathes without the double cross slide.

Check out the video in post 1 at 2:28 and you can see the upper and lower cross slide on this different model Oerlikon lathe. Maybe the owner also had a lathe like the lathe in the video, liked it, and added the xy table to this lathe. Who knows?
 
The ad says the seller added the cross slide.

What I don't get is he also says the spindle does not reverse, rather, you reverse the lead screw. That seems unworkable...

I worked in a place with a Mauser years ago ... I'm sure they have different models but this one was a man-killer, a total brute. We had Monarchs too but this thing was where you went to rough stuff out, I'd put 1" square HSS in it and plunge into a face. 18" swing maybe, made the Monarchs look like pansies.

We only ran it when necessary :)
 
So is the ability to reverse the spindle.

Clutch spindle reverse is 1000x more useful than leadscrew reverse.


I guess I should have been more specific. The Ebay description does not say you cannot reverse the spindle, it Indicates that the machine has a lead screw reverse.

At least that is how I interpreted the text.



Oerlikon Swiss Schaublin lathe.
This is amazing machine hydraulic shifting 4 speed on the handle speed selection is amazing 31 RPM to 2800 RPM check online about this late or I can FaceTime you so you can see Machine running everything works great in beautiful condition. There is another interesting feature for trading. You don’t reverse Spindle. There is a lever that reverse lead screw let me know if you have any questions local pick up I can load on your flatbed truck for free
Machine is metric, and I have transformer, but compound cross slide on the top is inch I added this feature original compound top slide is available several study rest three jaw and 4 jaw raishauer chuck ……..
Rapid feed on the apron you can also connect tailstock to apron and use of power feed to put in position

I totally skipped over the bit about the added cross slide. Then I saw tge video if the other machine and that cemented my ommision. Thanks for pointing that out.

The seller is totally out of touch pricewise. Wonder if he'll ever lower the price enough to sell it? It's still good machine tool porn.
 
That’s a very nice machine. The price is off the scale I’m afraid. Not being able to reverse the spindle is a bit of a downer. How do you go on if you’re tapping with a fairly large tap ?
