The Mikroturn® Base Line is able to achieve micron accuracies in hardened steel due to superb static and dynamic stiffness and the thermal stability of the machine. The construction is unique due to the application of a fully hydrostatic and wear free main spindle and slides together with the use of a very stable natural granite machine base.
All Mikroturn® machines have a natural granite machine base with an integrated vibration damping system. Natural granite is the perfect machine base. It is completely stress free , has very good damping properties, is corrosion free and has a low thermal expansion coefficient improving thermal stiffness.
All these characteristics make natural granite the perfect base for an ultra precision machine. Natural granite base:

Hembrug Machine Tools designs, builds and sells worldwide for more than 50 years the most accurate hard turning machines under the name Mikroturn®. The Mikroturn® series enables manufacturers to produce workpieces with complex contours in the highest accuracy class up to a Ø 1,500 mm with hardness up to 70 HRC. The machines have oil bearings throughout ensuring that the high degree of accuracy can still be delivered after twenty or thirty years.
The Mikroturn® machines are widely used and can be found worldwide in various precision industries such as the bearing and automotive industry. Hembrug offers 5 horizontal and 5 vertical versions of its machines. The horizontal are meant for small to medium sized workpieces up to a diameter of 500 mm and 300 kg in weight. The Vertical are meant for large workpieces up to a diameter of 1,500 mm and 2,000 kg in weight. Hembrug also supplies its machines with turnkey automation and post-process measurement equipment. Or hybrid machines with grind or tape-finish capabilities.
The Hembrug headquarters with 65 workers is located in Haarlem, the Netherlands. Hembrug also has a sales office in North America and works together with a variety of agents around the world.
