Hembrug

Hembrug, based in The Netherlands, is the benchmark for fully hydrostatic precision hard turning solutions

Since 1973

Leaders in hard turning. More than 50 years and 700 high-precision turning solutions developed for customers all around the world.

Ultraprecision

Hembrug machines are among the most accurate in the world.

Dim. tolerances of ≤ 0.000,08” (2 µm)
Roundness of ≤ 0.000,02” (0,5 µm)
Ra of 0.000003"-0.000015" (0,1–0,4 µm)

> 25 years

Accuracies last more than 25 years. Hembrug offers fully hydrostatic finish hard turning solutions.

Hydrostatic technology enables wear-free operation in the main spindle and slides.

Complete complex workpieces with sub-micron tolerances

Hembrug is ideal for machining complex and hardened workpieces in a single set-up and with sub-micron qualities.

You won’t need further post-processing and quality control will be less intensive, cutting your cost.

3 specialized hard turning machines

Hembrug has the right machine for every need:

Horizontal hard turning
Hybrid machines with hard turning and fine grinding
Vertical hard turning

Hembrug machines address a wide variety of workpieces and materials

Toolholders, dressing tools, machine tool spindle shafts, punches and dies, neck rings, rollers, gear pump shafts, pistons for radial and axial motors, ball screw nuts, and much more.

Our challenges

1679

Founded by the Dutch Government as Artillerie Inrichtingen (A.I.) for the production of ammunition.

Our challenges

1835

After the invention of the steam machine, A.I. started to develop and produce machine tools in-house, such as specific turning lathes, which they needed for ammunition manufacturing.

Our challenges

1940

A.I. started to sell machine tools to other companies for civil purposes.

Our challenges

1969

The first turning machine with a hydrostatic main spindle for the manufacturing of memory discs, which require a very smooth surface finish.

Our challenges

1982

Hembrug moved to Haarlem and focused only on the manufacturing of high precision, fully hydrostatic turning lathes under the name Mikroturn.

Our challenges

1999

Introduction of the Vertical-Mikroturn series for large workpieces up to a diameter of 39" (1000 mm). This would be the first model from the vertical product range.
