Lathes – Hembrug Machine Tools Mikroturn® Baseline (en translation)

Ultra precision. It all starts at the 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:

• Good damping properties
• High thermal stability
• High static and dynamic stiffness
• Free of stress
• Corrosion free

Hydrostatic slides and main spindle.

The main spindle bearings and slide guideways are the most important machine elements in a lathe, determining part accuracies of the workpieces and the lifetime of the machine.

The current Mikroturn® machines entail more than 40 years of engineering knowledge in hydrostatic bearing systems and guideways.

The hydrostatic system in the Mikroturn® Machine series is far superior to any other conventional system and offer many advantages.

• Excellent running accuracy
• Superb damping properties
• High stiffness, independent of speed
• Good thermal stability
• No wear and thus everlasting accuracy
• Longer tool life
