Hembrug Lathe Manuals

  1. Hard turning is the technique for making high precision workpieces with complex contours. It offers many advantages when compared to cylindrical grinding.
  2. Artillerie-Inrichtingen was a Dutch state-owned artillery, small arms, and munitions company which also produced machine tools and was founded in 1679 in Delft, Netherlands. The company was split in 1973 with its defense related businesses becoming Eurometaal and its civilian manufacturing becoming Hembrug Machine Tools.
  3. That famous little Dutch AI Hembrug lathes are about the biggest possible for hobby use into a non-industrial garage. If you live in a ex-farm, or ex-blacksmith shop or similar, yes in that case things change. Eeeeh with exeption of the transport problem ofcoarse. And the proper installing. And the handling.

I am not contributing to this great forum in the way I would really like to, but I hope you guys forgive me (for now). The things that some of you produce in your barn/shop/shed/garage, in my country we address to it as garage, is just stunning. I've collected many manual tools of all sorts over the years including quite rare ones and precision measuring tools. Not to mention all the blueprints and manuals I could find in the field of gunsmithing.
As of now I'm the proud owner of a long version AI Hembrug precision lathe I've taken it completely apart to examine and repair/replace the necessary parts.
The reason I chose this lathe is because it was made by Artillerie Inrichtingen (“artillery workshop”) hence the abbreviation AI, the same Dutch company responsible for all of Holland’s armoury and the AR-10 among other things.
Long story short, the precision-lathe I now have at home can be fairly easily adopted for all kind of gunsmith jobs. So restoring it to its former glory should be a great start in restoring my collection of firearms and gunsmithing jobs for friends.
One day I hope it would look similar to this one (mine has a longer bed)
I’ve got an independent 4-claw, a 3-claw, automatic collet attachment, steady rest and some tools with it.
The rear of the spindle has an hole for attaching the automatic collet or an indexer.
Mine is a 2000 RPM version with only automatic feed along the Z-axis.
The rear end of the spindle can be reached and the diameter thru it is about 1” or 25mm this should just be enough for my barrel work.
I would like to make a cat head that I can attach to the rear of the spindle for the purpose of reaming. But I’ve got a question about that.
I’ve read that some of you guys use some sort of reamer attached to, by lack of better words, hydraulic tube similar in principal to a gundrill. I have a hydraulic pump and could make closed type of cat head so that I push-ream through the barrel with cutting fluid being forced out of the hydraulic tube just rear of the reamer and by some pressure seal along the reamer thereby removing the chips.
A pull through reamer has of course other benefits. What do you guys think I should do accessory wise to my lathe. A taper attachment can be attached or made by example or should i opt for another motor and make it a 4000 RPM version. I will try to make an automatic X-axis feed, the arbor has all the work done but is missing some gears and axle's.
The jobs I want to do in the future are foremost for antique single barrrel shotguns;
Reaming and (re)chambering barrels;
Straigthening barrels;
Making missing and damaged parts such as firing pins, pistons etc.

That looks like a very nice machine, skiller. I hope yours can be made as nice.
For cutting chambers (chamber reaming) you really don't need any more than a can of oil and a reamer. High-pressure oil is just a convenience and probably only worth it if you're going to chamber many barrels.

I bought a hembrug lathe about 2 years ago, Haven't had a chance to work with it yet, but it cam fully equipped, lots of tooling, collet set and taper attachment. Let me know if you need any pictures or info to get yours set up.

Posted: Jul. 2 2013, 17:27 ET

Thanks Hawkeye2, I will certainly keep that in mind.
From this website you can download a shop manual which is also in English when Dutch or German isn't your mother tongue. The translations are a bit off but still a picture tells more than a thousand words. https://skydrive.live.com/?cid=54....33;1822 (search for Hembrug)
Currently I am working on modeling every part in 3D (I'm neurotic I know) so I can modify everything in 3D without a change of damaging the real deal until I'm fully confident it should work.
GeneT, I really value your opinion so if it was up to you, you would leave it as is I recon.

Thats a beautiful lathe. We need some starting pics of yours so that we can appreciate the end result!
As to your question about RPM, you probably won't need more RPM unless you're planning on using carbide tooling with small diameter stuff. HSS isn't very finicky about speed, and it runs at about half the speed of carbide.
For HSM HSS is probably a better choice anyway because it can be resharpened over and over again, but it's hard to beat the convenience of carbide inserts (especially if you're like me and just learning how to grind cutting tools).
Honestly, if it were me I'd just focus on getting what you already have up and running, and then decide from there what modifications you want to do.

wish we had an edit option...
Just saw the pics, you made out like a bandit! The tooling alone is probably worth what you paid!
Looks like a lot of fun to be had.

Posted: Jul. 3 2013, 04:29 ET

Wow, that truly is money well spend!
L stands for Links or 'Linksom' (Left, 'to the left' or counterclockwise) and R for Rechts 'Rechtsom' (Right, 'to the right' or clockwise), altough you've probably found this out yourself by now.
I've got the same collet attachment as shown on your lathe. I will post some pics tonight when I get home from work. Although I just realise I haven't shot enough before pics yet and already started to work on it.
Thanks for all the helpfull replies.

There were 2 old AI lathe's both of which I took apart with my students in class. The one on the foreground was rebuild with new bearings along with some better quick wearing (sacrificial and replaceable) parts and the motor from the one in the back. As my wife didn't allow me to take a lathe home I restored it to a very good usable condition, although left rough on the outside, and traded it with a local artist for Brass-casting lessons for my students. Got a pretty good deal for it and still had a reasonably fair and complete lathe plus my students had a good learning experience in maintenance so I forgot about the other one, but it kind of followed me home...
As I've got limited space in my shop and the big and bulky cast iron base weighs in around 1000lbs (500kg) and the bed and headstock are combined in a very solid casting I decided to leave the foot in the scrap yard. Sacrificing a bit of rigidity for a little more room, besides I couldn't get it placed not even with hoists. Still have to work around the shot motor, have to figure a solution for that and make an electrical 380V output in my shop.

Luckily I found a few additional old boxes with spare parts belonging to these lathe's just after the trade. So there were some extra goodies. Including a set of brand new primary reduction change-gears for reversing the rotational direction.
Along with a life-time supply of felt wipes and some other parts.
Although not exessively worn, the bottom gear has a slightly chipped corner on one tooth, still it was replaced.
The first series had Hard-fibre gears instead of these later nylon ones of which I've also got 1 spare.

Posted: Jul. 4 2013, 05:25 ET

Wow, beautiful lathe. It's a true shame you couldn't buy a lathe of that quality today.

Posted: Jul. 8 2013, 18:27 ET

beautiful machine!

Wrong pic. and can't seem to delete it. Mods feel free to delete the post above.
Thanks for all your kind comments, I sanded and then grounded all the surfaces which should have paint. As you can clearly tell in the picture I'm not that good of a painter... The side facing us is scraped by the way. All the bronze bearing bushes can be pressed out and are held in place with grub screws, really well designed.

Artillerie-Inrichtingen was a Dutch state-owned artillery, small arms, and munitions company which also produced machine tools and was founded in 1679 in Delft, Netherlands. The company was split in 1973 with its defense related businesses becoming Eurometaal and its civilian manufacturing becoming Hembrug Machine Tools. During its years of operation as Artillerie Inrichtingen, the company manufactured armaments and an array of other industrial outputs for the Dutch Army and the Royal Dutch East Indies Army (KNIL).

History[edit]

17th Century Delft, Netherlands
Pdf

The tribulations of the year 1672 emphasized the neglected state in which the army of the Republic of the Seven Provinces found itself. Therefore, in 1677, Willem III of Orange founded the corps artillery. In 1679 the State Prosecution Company in Delft was established. It was not the only one in the Netherlands. For example, the Grof Geschut Gieterijin in The Hague and the Geweerfabriek in Culemborg were also known. With the creation of United Kingdom of the Netherlands in 1815 following the Napoleonic Wars and the period of French Occupation, there was a need for a strong army in order to provide a buffer against France. The artillery was improved under the direction of Prince Frederik. Arms production was reorganized and came under military leadership.[1][2][3]

The Delft Company[edit]

Hembrug Lathe Manuals
The Battle of Waterloo, 1815

In the period of peace between Waterloo in 1815 and the Belgian Revolution of 1830, the Delft company developed rapidly. By 1813, the company was already utilizing steam power and producing artillery, field guns, small arms and military vehicles. Other products were manufactured in facilities located in Liège, but this ended after 1830 when the Belgian Revolution geographically split off these facilities, leaving the company's production entirely in Delft. Again, a reorganization was undertaken and non-core tasks such as woodworking were rejected. The company focused its efforts on metalworking under the leadership of Colonel Ultich Huguenin (1755-1833). The company began to manufacture small arms and ammunition as well, while continuing to produce machinery and precision instruments. Because it was also a miningplant, lathes were required for the machining of artillery munitions and the like. Their manufacture of precision instruments required custom machines and, by 1836, the company was producing lathes for their own use. By about 1850 there were 500 people in the company. The quality of production was high.

In 1860 a pyrotechnicplant was set up for the manufacture of explosives. About 1880, the company consisted of a logistics center, a pyrotechnic school, a foundry, a workshop, a saddlery, a woodworking center, a gun shop, and a patternfactory. In 1884, the company introduced a small foundry for cast steel, which was the first industrial scale steel production in the Netherlands. With this addition, the company began using cast steel for the production of war materiels which were previously manufactured from cast iron or wrought iron.[1][2][3]

The Hembrug Company[edit]

Artillerie Inrichtingen workers at the Hembrug plant use lathes to turn projectiles in the production of 75mm naval artillery shells Zaandam, Netherlands, 1912.
70MM Cannon Production, 1921.
Rifle stock production. Zaandam, Netherlands, 1912.

In 1887 the company was renamed Artillerie Inrichtingen (A.I.).[3] From this point, all production was no longer centered in Delft because the Hague Grove Geschut Gieterij was also included in the company. As the company's existing facilities had no space left to expand, a new site was sought. However, this search was limited to the territory within the defenses of The Stelling van Amsterdam.[3] The company chose a new base of operations near Zaandam, where there were already some naval pilots[translation from Dutch article needed].

In 1899, Artillerie Inrichtingen moved to the Hemelveld on the Noordzeekanaal near Zaandam. The Hague shuttles were closed in 1904 and the services moved to Zaandam. In 1907, a gangway bridge was opened over the canal called Hembrug. Eventually the name of the bridge would pass on the company.

In 1912, Artillerie Inrichtingen was re-designated as a state-owned company, and was thereby withdrawn from the direct military authority. At this time, the company employed some 1200 people, including many soldiers. Most of its production was then going to the Dutch East Indies to suppress rebellions of the indigenous peoples, such as those the Aceh Wars.

After the outbreak of the First World War, production and staff increased quickly, reaching a height of 8500 people in 1917. Arms production increased by the large orders for the Dutch army. After the end of the war, the country entered a period of disarmament with the establishment of the League of Nations. The number of employees fell to less than 2000 in 1921 and closure of the company was considered. As an alternative, automobiles were assembled and converted. The company also employed 200 drivers delivered mail, until this function was transferred to the 'Mailies' of the Dutch National Postal Service in 1930.

In 1928, the organizational form of the company was changed to that of a public limited company which allowed for greater freedom of business management. The largest customer was still the KNIL, and the number of employees slowly recovered, before later falling back to 1200 in 1932 during the Depression, despite an increasing demand for the company's civilian production, including lathes. The German re-armament of the 1930s also led to increases in production. In 1940, a plan was put in place to deny the NAZIs use of Artillerie Inrichtingen's facilities, but this plan was not implemented before The Invasion.[1][2][3]

World War II[edit]

Wartime DutchNSB Rally

During the German occupation of the Netherlands, Frans den Hollander remained Director of Artillerie Inrichtingen, but he had contact with the Dutch government in exile. The Nazi's demanded immediate reopening of the factories following the surrender of the Netherlands, but Den Hollander and his superiors, Dutch Commander-in-chiefHenri Winkelman and Secretary-GeneralCornelis Ringeling refused this initially, and succeeded in delaying the resumption of production for about a month. On June 20, 1940 production resumed. The Nazis kept the plants working during the war, but the workforce fell sharply. The company also tried to make as many civilian products as possible. This could be because the machine factory was sold in 1941. The Delft factory was also dismantled in secret in 1941. In 1944, when the Allies began to advance throughThe Low Countries and through the Hunger Winter the Artillerie-Inrichtingen factories were closed.[1][2][3]

Post War[edit]

After the Liberation in 1945, the company was restarted. The company, with the support of the Marshall Plan, produced agricultural tools such as seed and weeding machines and potato sorting machines for the post-war mechanization of Dutch agriculture. Thanks to the war in Dutch-India and The Cold War, there also remained a high demand for the company's ammunition and weapons production. It was during this time that the company became involved in the manufacture of AR-10Battle Rifles for the Dutch, Portuguese, and Sudanesearmies. This iconic rifle is the predecessor or the M16/M4/AR-15 series rifles, one of the world's most prolific assault rifle designs. The AR-10 was adopted by the Portuguese Paratroopers and came to be an iconic symbol of the Angolan War of Independence and the broader Portuguese Colonial Wars. The company also continued its long-standing production of lathes which led to numerous innovations. With the introduction of CNC Machining, the company's lathe making arm specialized in precision lathes from 1969 and went on to eventually become the Mikroturn division of Hembrug Machine Tools.

Eurometaal Headquarters

[1][2][3]

1973 Split[edit]

In 1973 the Dutch government divided the company into two independent parts: Eurometaal, and Hembrug Machine Tools. Eurometaal took the company's military production facilities including those for arms and armaments, while Hembrug took the precision tool manufacturing. In 1983, the privatization of Hembrug followed the company moving to the Figeeweg in the Waarderpolder in Haarlem. Hembrug went on to develop ultra-precision lathes. Eurometaal also sought to target the civil market and manufactured parts for cars, forklifts, milking robots, high-precision precision tools, light commercials, sailboats, and durable locks. It also developed a press for the production of coins for the Dutch Mint, which struck guilders and later euro coins. A unique technical event was the acquisition of a 3000-tonsoil pump, which was the largest in Europe in terms of capacity and stroke length.[1][2][3]

Acquisition and repatriation[edit]

Rheinmetall

Eurometaal was eventually taken over by the German Rheinmetall and stopped production in 2003. The Eurometaal subsidiary at Bergen op Zoom, called Franerex, was also closed in 2003. Companies in Eurometaal Holding including Intergas at Coevorden and the GermanHeidel, which worked for the automotive industry, were rejected for a social plan for the last 200 employees. In the old mansionworkshop at Zaandam, the Tetrix training center was established in the old Artillerie Inrichtingen masonrypatternfactory, founded in 1939. They left the site in 2012.[1][2][3]

Present[edit]

Production in the Hembrug area declined through the 1970s until the train stop serving it shut down in 1982.[4] The old Artillerie Inrichtingen Hembrug factories fell into disuse. In 1983, the Hembrug Bridge, for which the area was named, was made obsolete by the Hemtunnel, then torn down in 1985. The former munitions factories were replaced by Eurometaal, then Rhinemetall facilities. As of 2017, the Hembrug Machine Tools company still makes precision lathes including the Mikroturn line in Haarlem. There are still a large number of industrial manufacturing plants in the Hembrug area, and the area is considered as an important industrial monument. On the site of the old Artillerie Inrichtingen Hemburg factories, the Hembrug Museum is furnished to provide information about the past, present and future of its activities.

Association with the AR-10 battle rifle[edit]

Artillerie Inrichtingen produced Sudanese AR-10

Hembrug Lathe Manuals Free

On July 4, 1957, FairchildArmaLite sold a five-year manufacturing license for the AR-10 to Artillerie Inrichtingen. The AR-10 was invented by Eugene Stoner in 1955 as a late entrant to the United States Army's Light Rifle Trials to replace the M1 Garand in US service.[5] It was a revolutionary design in many ways, but lost the competition. It had however caught the interest of Foreign militaries which led to Armalite's deal with Artillerie Inrichtingen whose large factory and production facilities were felt could produce the ArmaLite rifle in the large quantities Fairchild anticipated would be needed to fulfill expected orders.

A.I. officials meanwhile discovered a number of manufacturing and production issues in the 'Hollywood' (Armalite) version of the AR-10, all of which had to be resolved before large-scale production could commence.[5][6] In addition to designing and building tooling for the rifle, the design had to be converted to metric dimensions and subcontractors had to be found to supply materials or manufacture component parts.[5][7] ArmaLite also continued to send A.I. product improvement requests.

AR-10 production was limited, though Guatemala,[5][8] Burma, Italy, Cuba, Sudan and Portugal all purchased AR-10 rifles for limited issue to their military forces[5][9][10][11] with examples eventually turning up in unofficial service with various African and colonial armies, police, and guerrilla forces.[5][12] The AR-10 remained in service with Sudanese Special Forces until 1985.

The final Artillerie Inrichtingen design is known as the Portuguese model AR-10. It is believed that approximately 4,000-5,000 Portuguese variants were produced; nearly all of them were sold to the Portuguese National Defense Ministry by the Brussels-based arms dealer SIDEM International in 1960.[5][11] The AR-10 was officially adopted by the Portuguese Paratrooper Battalions (Caçadores páraquedistas), and the rifle saw considerable combat service in Portugal's counter-insurgency campaigns in Angola and Mozambique.[13]

Additional sales of the AR-10 rifle were stymied after the Netherlands embargoed further shipments of the rifle to Portugal. The A.I. produced Portuguese AR-10s continued in service with a few Portuguese airborne units, and was in use as late as 1975 in the Portuguese Timor (East Timor) decolonization emergency.[13]

Fairchild-ArmaLite was dissatisfied with the delays in setting up the tooling and production at A.I. for the AR-10, and made it clear that they would not be renewing A.I.'s license to produce the rifle. By 1960, hampered by Dutch export restrictions and discouraged by the lack of arms sales to major national purchasers, Artillerie Inrichtingen decided to exit the small arms production business altogether, and ceased all production of the AR-10 under its license from Fairchild-ArmaLite. By that time, fewer than 10,000 AR-10s had been produced, mostly military select-fire rifles, with a few semi-automatic only rifles produced for civilian use. All A.I. AR-10 parts inventories, tooling, and prototypes were either sold or scrapped; the barrel tooling was sold to Israel sometime in the early 1960s. All AR-10 production records, design drawings, manuals, literature, and other publications then in inventory were discarded.[5][14]
