The maximum collet capacity was 0.75' (18 mm).ДЄ 3-speed, 1 h.p. 4 Morse taper, the spindle ran in a double-row cylindrical roller bearing at the front and a pair of single-row angular contact bearings at the rear as an option, a set of ultra-high precision bearings could be supplied that the makers guaranteed would allow a surface finish to be obtained on a 1-inch diameter brass bar - over a length of 1.25 inches and using a diamond tool - of better than 0.075 microns. With a D1-4' nose, 26 mm (just over 1 inch) bore and a No. A machine of superb quality, with headstock and V-way bed cast as one massive unit and mounted on a heavy cast-iron stand, the A1 is now sought after by knowledgeable enthusiasts and prized for its great attention to mechanical detail, handsome appearance, rigid construction, ease of operation and wide speed range. Over many years Hembrug has manufactured a wide range of ordinary and specialised machine tools including a very desirable precision toolroom lathe, the 'DR1', of 5.25 inch centre height by 18 or 30 inches between-centres (133 mm x 470/750 mm) that was manufactured in Hembrug-Zaandam. Today work continues, helped by an association with the Technical University of Delft, with recent Mikroturn developments including the integration of boring and honing and production of a complex 4-axis version with the ability to simultaneously turn inside and outside diameters. In 2000 a new building was erected on Figeeweg 5a together with an enlargement of the existing assembly area. The range was then steadily expanded with the introduction of various models for both small and large diameter work and vertical machines to handle even bigger jobs.

In 1990 a new research facility and production plant was built where development and production of ultra-precision hard-turning machines could be concentrated - and by 1994 small-scale series production of the Slantbed-Mikroturn 100 CNC. In 1973 (and still under state ownership) the machine-tool, general engineering and ordnance activities were split, with all but the latter designated as the 'Hembrug' company that became, in 1982, the privatised concern 'BV Gereedschaps-werktuigenindustrie HEMBRUG B.V.' Having moved to the city of Harlem the company dropped its miscellaneous activities (including the Figee crane department) and began to concentrate on an increasingly important sub-set of lathe production, ultra-precision, fine-finish hard-material turning machines, the origins of which can be traced back to 1969 and the company's first 'Ergomonic' and 'Mikroturn'models (these lathes are shown towards the bottom of the page). However, it was not until the 1930s that the company branched out into machine tools, at first specialised products for the manufacture of ammunition. Of their lathes, the writer would be delighted to hear from youД«eginning life in 1679 as 'Artillerie Inrichtingen' (the Dutch Government's ordnance works intended to make the state independent of outside suppliers) the Hembrug Company have long enjoyed a reputation for high-quality engineering with their diverse activities even including being one of the makers of propellers for the English Sopwith Camel fighter aircraft of WW1.

I hand cut/filed these discs from a piece of old copper water pipe (5mm diameter) but a simple 3D printed 5mm disc would probably suffice.Email: t Machine Tool Archive Machine-tools Sal e & Wanted There is a small 5mm copper disc (item 29 in the Hembrug parts diagram) between the end of the set-screw and the thread of the adjusting screw to prevent damaging this thread. The original set-screws that are used to lock the adjusting screws in place are M6 x 20 (item Q in the original Hembrug parts diagram). The original screws that tighten the blocks against the underside of the lathe bed are M8 x 30mm (item M in the original Hembrug parts diagram).

The LH guide block was made based on the RH item but slightly wider to fit the available space - I did not have the dimensions for the original LH guide but I assume that this one is wider than the original. The RH guide block was designed based on dimensions provided to me from an original Hembrug part. I originally made these guides as prototypes intending to make steel items once I was happy with the dimensions but they have worked so well (just over a year in service so far) I haven't replaced them. My Hembrug DR1 was missing both of the original carriage guide blocks.
