Despite of the relative large count of dutch forum members there are but a few topics about dutch made machines. (mainly lathes)
Time for a dutch millingmachine. I think the dividingset is original but I'm not sure. It is very suitable to make smaller gears on this machine. There was also a version with hydraulic feed on the x-as.

The AI Hembrug FR1A.


It's a relatively small machine but it has accesoires for the basic needs:

Horizontal milling


Vertical milling


Slotting.


There's more information on the webpage AI Hembrug FR1A

I never liked them You could hardly call it a milling machine Sorry but I liked their lathes better
And their is just very little dutch machinery
At the moment we still have Hembrug (hard turning ) Style
(teach in lathes and milling machines) and Unisign (CNC milling machines)
That is all for as far as I know

An interesting machine, thanks for posting. Looks very rigid for its size. I think I'd prefer more surface area on the table, though (and more than one T slot!)

The edges can be used as table area as well. Your right about the one T-slot it would be easier to have more. I am considering converting the slits on the sides to T-slots.
I don't know the original market for these machines. Maybe clockmakers.
Hembrug had quite a wide range of products they made.
Originally they manufactured rifles, bajonets, helmets, grenades, canons and other stuff for the army.
Besides that they made this milling machines, drilling machines, vices, the famous toolroom lathes (and bigger versions) and also very good (tool)grinding machines (more about the latter will follow).

leave the t-slots alone
leave it like it is ...dont alter it in anyway ...
because it an interesting piece of machinery that should be kept just as it was designed .,

just use it as a second mill .when the other has a set up that cant be disturbed.

my fritz werner only has one t-slot ......and i cant see anyway that it will hinder anything to be done on it.

all the best.mark

Well...as a Dutchman I think I have to join in on this one... [img]smile.gif[/img]



As you can see, my mill has a separate table with three slots and is bolted on the main (x)table...

I think Hembrug made this mill in different specifications over the years. f.i. The pedestral of my mill is straight and has no casted chippan... I've allso seen these mills with a lever operated crosstable used as a horizontal grinder...

Yoyo, I see some drawings on your website...Do you have a manual.!!!! I'd love to have a copy !

Gerrit that's a nice solution regarding the T-slots, although it takes some of the limited available hight. I guess it can easily be screwed off to make place for a vice.
Your (nicely painted by the way) machine is indeed completely different from the ones I've seen. Only the dials look familiar to mine.
The motor mount looks somewhat complicated, is there a V-belt tensioning-system build in the mount ?
Since I got the drawings and lubricating scheme for free (Jan nog bedankt) . I'll be happy to shoot the pages (it can hardly be called a manual) through to you.
Your absolutely right Mark, deep inside I knew the answer to my doubts already but sometimes one needs to be remembered. I go for Gerrit's solution or I make a bolt-on flat plate with a 1" square tapped hole pattern. I'll sleep on that for some time.

Hi all,

I have looked at those for a while for my 'home shop' and had one offered to me but I declined as the capacity is relatively small and so is my shop. So I can't afford the luxury of a separate mill adn drill.

So I opted for a Arboga Mill/Drill instead.

My question is, does anyone know what purpose these fairly small but ridgid machines were build for? Was it just for schools?

I like there lathes as well but prices overhere are quite high for, mostly, worn machines.

Think I have found room for one of their equally small shapers though.

Regards,


Piet

Hello,

Someone sent me the manual of the A.I. Hembrug Mill, and maybe it's also interesting for you: Manual A.I. Hembrug mill

By the way, this is my small A.I. mill:

Feike thanks but I already have that scan (and the original) although I didn't send it to you.
Also I have a copy of a manual that only consists of the first part regarding the MK3 version of this mill.
Interesting here is the SK30 version as described in the second part. The old manual mentions 16 mm overarm as standard equipment and 13 mm as optional, where as the newer manual doesn't mention a standard overarm and has a 16 mm arbor as optional listed. And also a very different flatbelt driven vertical head is described.
Your mill looks great. Im curious to the code on top of the vertical slide of your mill, is it FR-1A or a FR-1D ? Did you repaint it this nice grey colour or was it originally grey ?.

Thanks for the manual Feike !. Yoyo sended me a scan of his version and he's right, the two manuals are differend.
A year ago someone mailed me a picture of his AI mill fitted with the interesting flatbeld SK30 head. Here's the picture:


Till now, It's the only one I've ever seen with the special SK30 shaft....

Regards,

Gerrit

Those are neat looking little machines, and well tooled. Nice to see so many overseas guys posting regularly as well.

That's a very nice picture indeed. I also own one with the Sk30 shaft. Its not only the Sk30 thats different, the bearings are much bigger with double rollers on each side.
I haven't got the vertical sk30 millinghead though.
I suppose the complicated power transmission is a result from the struggle for hight under the vertical head. Because of the much bulkier spindles there's not enough room to make a direct coupling with crowngears between the vertical and horizontal shaft.

hello there,

sorry for opening up an old thread ,but i recently acquired me one of these beauties and just set it up.

Although the most friendly supplier did even supply me with some documentation i would off-course love to own the óriginal' rather complete manual ,so if any enthusiasts still own a digital copy i would be most thankfull for an e-mail p-mail ......

Stay put for the gloat ! muhaha
