Introduction of the Mikroturn 100 with a tape finishing unit to meet the highest market demands on surface finish quality.



Introduction of the redesigned Mikroturn Twin Spindle. The redesign reduced price by a third while maintaining functionality and precision.


Introduction of the Mikroturn 500 XL for large and heavy workpieces up to 500 mm in diameter and 300 kg in weight.


Introduction of the Mikroturn® 200 L for long workpieces up to a diameter of 380 mm or 240×900 mm between centers.


Introduction of the Mikroturn Twin Spindle. A dual spindle machine for small workpieces up to 100 mm in diameter. The dual spindle design makes production increases up to 100% possible.


Introduction of the Mikroturn® 1000V. A 2-axis vertical turning machine for workpieces up to a diameter of 1,000 mm and 2,000 kg in weight.

History 12


Opening of new assembly hall. This temperature controlled hall is especially designed for the assembly of large machine tools.The new building also creates the space needed to expand other disciplines, such as engineering, R&D and production management.


Introduction of the Mikrogrind 1400 V4. A hybrid Vertical machine with hard turning and cylindrical grinding capabilities.

History 9


Start development 4-axis Vertical-Mikroturn® 950 CNC allowing to simultaneously machine inside and outside diameters of large ultra precision componants. This simultaneous way of machining allows a reduction of cycle-time up to 40% compared to a two axis way of machining.

History 8


Start development of the Vertical-Mikroturn series for large large componants up to a diameter of 1.000 mm.

History 7


Development of the Slantbed-Mikroturn 50 CNC for finish hard turning of small sized componants up to a diameter of 120 mm.

History 6


Development of the Slantbed Mikroturn® 100 CNC, specially designed for finish hard turning of medium sized components up to a diameter of 310 mm.

History 5


Start of research of finish hard turning within submicron (It 3-5) tolerances on the Mikroturn® series.

History 4


In 1973 the Dutch government separated A.I. in two different companies, EuroMetaal and Hembrug. In 1982 Hembrug was privatized and moved to Haarlem. Hembrug decided to focus completely on the development, assembly and marketing of precision and fully hydrostatic turning machines.

History 2


A.I. started selling machine tools to 3rd parties under the Hembrug brand name. More than 10.000 have been supplied worldwide since then.
