The Mikrosa KRONOS S 125 centerless grinder is the ideal system decision for economical precision processing of small parts. The special feature of the KRONOS S: It can be converted into a 15° inclined plunge cutting machine within 2 hours. In this way, applications which were only possible between centres can be processed alternately. If we look at it this way, the KRONOS S is really "two machines in one". It has been designed for universal use even with the smallest of batch sizes. 

The KRONOS S provides outstanding overall economy, above all in combination with the CBN high-speed technology.


 A further feature is the patented cross-slide system. The special cross-slide construction and the easily accessible arrangement of the dressing appliances have made easy adjustments possible. For plunge cut parts, a handling system which can be integrated with the machine is available. It can be combined with external workpiece stores without any problems.


Mechanical adjustments are no longer necessary for α' and B1 axis a sure touch is replaced by NC precision. This means: reproducible figures at the push of a button. The "µ hammer" is thus a thing of the past.



  • Unique: Settings for α' and B1 without mechanical movement elements thanks to Mikrosa know-how, resulting in a distinct reduction of the adjustment and set-up times plus an increase in reproducibility
  • Time benefit: 85% saving in the generation of the hyperbolic profile on the regulating wheel-75% saving in the cylinder correction on the workpiece
  • The Kronos system only uses 4 axis, where as conventional systems use 6 axis to achieve the same result
  • Highest dressing processing for grinding and regulating wheel by arrangement of the dressers in the centre of the workpiece level
  • Quick refitting into a 15° inclined plunge cut machine in less than 2 hours by a simple change of the grinding spindle unit.
